Before installing the pump station, it is necessary to properly prepare the base. When mining the soil in a mechanized way, with the help of an excavator, the pit should not be slightly modified to the design mark in order not to violate the natural integrity of the soil. The completion of the soil to the design mark must be carried out manually, avoiding digging, so that concrete base under the pump station it was mounted on the mainland soil.

Procedure

1. It is necessary to clean the surface of the bottom of the pit from foreign objects.
2. At the bottom of the pit, along the entire perimeter, a sand cushion 200 mm high is made with watering and tamping. According to the developed drawings, the formwork is assembled for reinforced concrete base... In the formwork, several layers of mesh are mounted, made of reinforcement of different diameters and different mesh spacing (as a rule, the mesh is made with a step of 100x100 mm from reinforcement Ø 10-12 mm, in 2-3 layers depending on the height of the concrete base and the size of this base). The dimensions of the bases for the sewage pumping station are developed by design organizations, depending on the size of the sewer pumping stations, soil composition at the site of installation of the pump station and the presence groundwater at the installation site. Next, the formwork is poured with concrete and allowed to settle. In various cases, use various brands concrete. In dry soils, M150 grades are used, and in moisture-saturated soils, moisture-resistant grades are hydraulic concrete M200, M 250 Concrete works must be carried out in accordance with all the rules of concrete work technology.
3. After the concrete gains strength, the installation of the pump station body begins. Before mounting the KNS body on the base, clean the surface from foreign objects.
4. When lowering the body into the pit, distribute the load from the body weight evenly over all mounting hinges.
5. The plastic case must be mounted strictly in the design position. After the body has been installed at the design level, you need to make sure that it is not damaged and is installed strictly along the design axes. Check the verticality of the cabinet. If the foundation is horizontal, the pump station will stand vertically.
6. After installing the pump station on a concrete base, holes (8-12 pieces, depending on the diameter of the station) with a diameter of 12-16 mm, 18-22 mm long) are drilled in the skirt of the pumping station along the entire perimeter for the installation of anchor bolts. After that, the bolts are inserted into the holes, hammered and tightened.
7. At high level groundwater, in addition to fixing the pump station with anchor bolts, to the concrete base, the lower part of the pump station must be poured with concrete about 0.5-0.8 m. The calculation of the weight of concrete is carried out in the scope of a working project or a project for the production of works.
8. After fixing the pump station to the concrete base, backfilling with sand is carried out, layer by layer with tamping and watering to the level of the supply and pressure collectors. Before backfilling, make sure that the SPS casing is not damaged. After installing the pump station on the base and checking its verticality, start backfilling. (Sandy backfill serves as a gasket between the pump station body and untouched soil and serves to protect the pump station from ground movements).

1. Then the pipes of the incoming manifold are connected and the pipes of the pressure branch are connected. The soil is compacted under the supply and pressure manifolds.
2. Then backfilling with sand is carried out in layers, up to the ground level with layer-by-layer compaction, evenly over the entire diameter of the pump station. Failure to comply with these conditions may result in deformation of the body or neck.
3. Then the pumps are installed in the pump station housing. Lowering the pumps along the guides in the pump station can be done manually (if the pumps are lightweight) or using lifting devices such as hoists or cranes (if the pumps are heavy).
4. Then it is mounted. The pump control cabinet, according to the project, can be placed on the pump station body in a special metal box (protection against vandals), near the pump station in a metal box or in any room located in the vicinity of the pump station. It is easier and cheaper for all to place the pump control panel on the pump station housing. At our production site, we have developed platforms with sealed inputs to the pump station, for the installation of metal boxes inside which there are pump control cabinets. Electric cables from the pumps in the standard have a length of 10 meters and if the pump control cabinet is located not near the pump station, then it is necessary to buy an imported, expensive cable for extension, which increases the cost of installing the pump station.
5. The next step is to connect the central cable to the pump control panel. The cable is selected depending on the power of the pumps and according to the project for the installation of the pump station.
6. Then, suspended floats are suspended inside the pump station for the operation of the pumps.

At the final stage of installation of the pump station, cables from pumps, from floats, from overflow sensors, etc. are connected. to the pump control panel and commissioning of the pump station is done.

floor, but if this equipment is average in size, then a pit is being dug for it or it will be necessary to place it in a special room of the SPS.

Today we will focus on the arrangement of the pit, including all regulatory components, namely:

Sanitary protection zone of the sewage pumping station, which must be observed within the established standards (about 15 m).

The requirements for the fencing of the sewage pumping station, if it is buried, can be observed, cleanly, due to safety measures or the safety of equipment, and so they put a lock on the cabinet and hatch, and that's it.

Observe the safety rules, and therefore, during the construction of the pipeline and the pit, in order to avoid traumatic situations, it is necessary to build barriers for the working area.

For the installation of a pump station, the estimate should include all the estimated costs:

• for renting special equipment for digging a pit and installing equipment;
• for the purchase and delivery of sand with concrete for the foundation of the sewage pumping station;
• for related tools and parts for fastening the tank;
• to pay a team of workers, if you do not plan to carry out the installation of a sewage pumping station with your own hands, etc.

And so, you have taken into account all of the above and are ready to proceed with the installation itself:

• A pit is being dug, in size exceeding the dimensions of the SPS structure. This is necessary for convenient connection of the rest of the pipeline and power supply.
• In order not to dig up the soil, the very bottom of the hole is dug manually.
• According to the drawing, the formwork is being built: a cushion of sand (10-15 cm) is made, reinforcement is installed and concrete is poured in several layers, using a level in order to make the foundation as horizontal as possible.
• Only after the reinforced concrete structure has completely hardened, the body is attached to it, taking into account that when installing the KNS, the deviation from verticality is permissible within 5 mm.
• Make sure there is no debris or water inside the tank.

The water must be pumped out, not poured out, overturning the body.

• With the possible appearance of groundwater, the structure is fastened with anchor bolts, or even poured from above with ready-mixed concrete so that the top of the concrete plane exceeds the lower stiffening rib of the equipment by 200 mm.
• After all the manipulations, backfilling is performed up to two collectors: pressure and gravity.
• Then the power supply and the pipeline are brought in.

Backfilling is carried out evenly along the circumference of the pump station, sifting out stones and tamping layers of 50 cm, at a positive temperature, by pouring water. V winter time keep in mind that the soil must not freeze through.

Attach the cover, ventilation, etc. with the supplied parts.

Sewage pumping station (SPS) is a set of equipment and tanks for pumping waste water. The need to install such a station arises in cases where the transportation of wastewater by gravity is impossible for some reason. This is where she becomes irreplaceable assistant... In this article, we will cover the main design features SPS, their types, as well as features of installation work and service rules.

Design and internal structure of the pump station

When choosing a sewage pumping station, the estimated volumes of wastewater, the size of the device, the degree of pollution of the wastewater and the type of pollution are taken into account. The choice is also influenced by the features of the relief of the land plot on which the station is installed, and the depth at which the conducting pipeline is laid.

SPS device for different purposes may vary significantly, but the main parts of the design - sealed containers and pumps - are present in all models. Usually, water is drained into the reservoir by gravity, after which it is pumped out by pumps and transported to the disposal site or to the treatment plant. There are mini-KNS that are connected directly to the toilet bowls. These are aesthetically pleasing sealed tanks of small volume, equipped with pumps with a grinder. Such models of KNS are usually installed in the bathroom.

As a rule, the SPS tank is a polymer tank buried in the ground. The neck of the tank is brought to the surface to facilitate routine inspection, repair and maintenance of the station. It is closed with a polymer or steel cover. Inside the tank there is a pipeline connected through branch pipes in the walls. The uniformity of water inflow is ensured by the baffle, and the absence of flow eddies is ensured by the water wall.

Sewage stations used for domestic purposes are equipped with 1-2 pumps. If the equipment is intended for the drainage of wastewater from utilities, there must be at least two pumps. Pumps are installed at the pump station for various purposes different types... For domestic stations it is better to use pumps with a cutting mechanism, for communal stations it is not recommended, since solid waste, falling into the sewer, can cause damage to the cutting mechanism.

The main structural elements of the pump station are a sealed tank and pumps

Requirements for the sewage pumping station, features of the installation and arrangement of the sanitary zone, required amount pipelines are regulated by SNiP 2.04.01-85 " Internal water supply and sewerage of buildings ”.

The principle of operation of the sewer station

Regardless of the type of SPS, the principle of operation of all systems is the same. The drains are discharged into the receiving part, which, due to the dense laying of water, do not seep into the ground, and under pressure are forcibly pumped by pumps into the pressure pipeline. Further wastewater enter the distribution chamber and are transported through pipes to sewage treatment plant... To prevent the drains from returning back to the pump pipeline, a check valve... If the volume of wastewater rises significantly, an additional pump is switched on. If the pumps cannot cope with the volume of waste water, an alarm is triggered.

The work of the pump station is controlled automatically. Control over the level of incoming waste is carried out using float sensors located at different levels, due to which the station operates in the following mode:

1. The first level sensors indicate a small volume of waste water, the pumps are not working.
2. The second-level sensors turn on the pump for pumping the accumulated waste. The volume of effluent is within normal limits.
3. Sensors of the third level are triggered with an increased volume of water and turn on a reserve pump to pump out excess wastewater.
4. Level 4 sensors trigger an alarm because the sewage pumping devices cannot cope with their volume. In this case, the maintenance team must take measures to normalize the operation of the pump station, since the alarm can turn on as a result of a breakdown of one of the pumps. To simplify maintenance, the sewage pumping stations are equipped with a hatch and a ladder.

When the pumping of waste is completed, the level of the effluent falls below the first sensor, the system shuts down. The next time it is turned on, another pump is activated, which previously performed the function of an additional one. Such a system of work prevents premature wear of the mechanisms of one pump.

Additional equipment that can be completed with a sewage pumping station:

• Backup power supply;
• Pressure sensors, manometers, valves;
• A metal pavilion that ensures the safety of the system and the safety of equipment;
• Equipment for cleaning pumps, connecting pipes.

The work of the station is fully automated, however, if necessary, it can be switched to manual control mode. Such a need usually arises during repairs, the need to clean the tank, or when a new SPS is put into operation.

Wastewater is pumped into the pressure pipeline, after which it enters the distribution chamber and is sent to the treatment plant

Types of sewage pumps and their features

Pumping equipment is the main part of the pump station. It pumps domestic waste water, industrial waste, sludge, storm water... There are these types of sewage pumps:

• submersible;
• console;
• self-priming.

A submersible sewage pump is a pressure-acting device that is constantly submerged. Materials for the manufacture of such a pump are selected to be resistant to aggressive media.

Most often, submersible fecal pumps are used in the sewage pumping station. They are efficient, easy to operate

The device is convenient and takes up relatively little space, since it is constantly immersed; there is no need to prepare a separate site for it and additional pipe junction. The advantages of this type of pump:

• reliability;
• ease of use;
• rare maintenance;
• the ability to work effectively at low temperatures;
• cooling by the surrounding and flowing liquid;
• versatility: pumps are also used for dry installation.

A cantilever dry-installed sewage pump is a device most often used in large industrial sewage pumping stations. These pumps are not installed in modular stations. When installing them, it is necessary to prepare a separate foundation and correctly bring the pipes.

Cantilever dry-installed sewage pumps require separate foundation, used in large industrial pumping stations

It is better to entrust the commissioning of such a pump to specialists. Cantilever pumps stand open, easy access to them, which greatly simplifies renovation work... Advantages of cantilever pumping devices:

• reliability;
• easy access to the impeller, engine;
• ease of maintenance;
• the ability to change performance due to correct selection electric motor and other structural elements.

The dry-installed self-priming sewage pump is a unit used in municipal and industrial sewage pumping stations for pumping highly contaminated wastewater.

Self-priming pumps are not subject to clogging, effective in negative temperatures... The only negative is the high price

These devices are service-friendly due to their flange-mounted motor design, and they do not clog due to the spacious passage in the nozzle and impeller. Device advantages:

• easy to maintain due to the retractable design;
• little prone to clogging;
• works at negative temperatures when installing a special heating element;
• pumps sewage drains with solid elements, sediment;
• maximum tightness due to double mechanical seal;

It should also be noted that, if necessary, such a pump can be easily dismantled.

Installation and maintenance of equipment

To install the SPS, a pit is dug, the depth of which is calculated in such a way that the tank lid protrudes 1 m above the earth's surface. sand pillow 1.5 m. Next, a reservoir is installed in the pit, pipelines are connected, after which the pit is filled with sand and compacted layer by layer. The density of the soil must correspond to 90% natural.

Then the pumps are installed in the tanks, the floats are regulated. The floats of the first level should be 0.15-0.3 m above the bottom of the tank. The next floats are set 1.5 m higher than the previous ones. Next, they mount electrical cables, connect the power supply, equip grounding. When checking the operation of the system and pump performance, use clean water from the water supply or cistern.

Installation and connection of power supply, grounding is carried out in accordance with SP 31-110-2003 "Design and installation of electrical installations in residential and public buildings".

To ensure the safety of the sewage pumping station, pavilions can be equipped - metal, concrete, brick

Service of the sewage pumping station is carried out in the following order:

• Visual inspection of the condition shut-off valves, pumps, check indicators of the control panel. If there are indications of abnormal pump operation, extraneous noise or vibration, the unit is removed from the container, inspected, washed and checked.
• Cleaning of the pumps and the station body is carried out clean water from a hose using brushes without using detergents... When cleaning, it is important not to allow water under pressure to enter the control panel, pressure gauges.
• Dismantling of pumps for inspection, subsequent installation. When installing the units, ensure that they are attached to the automatic pipe coupling.
• Maintenance includes checking the condition and cleaning the coarse debris trap.
• Routine repairs include replacing worn parts, tightening fasteners with wrenches.

When repairing the sewage pumping station, the maintenance personnel must adhere to safety rules and use protective measures. Dismantling of the pumps should be carried out only after the unit has completely cooled down; disconnect it from the system and relieve pressure.

The topic of sewage can only seem unpleasant to an inexperienced homeowner and only at first glance. As soon as problems arise with the sewerage system, their elimination becomes the most important task.

If troubles with stocks are of a regular nature, it makes sense to revise the original project for errors. To eliminate them, you may need a pumping sewer station. We will show you how to install, operate and maintain it.

SPS or sewage station is a device for the forced removal of solid and liquid effluents. Such devices are most often used for industrial purposes.

But there is whole line SPS specially designed for domestic use. They are usually installed in private households with or where it is necessary to ensure the transportation of waste to the riser of a centralized sewer system.

There are compact models of sewage pumping stations that can be installed under the kitchen sink. But connect a washing or dishwasher it is forbidden

Should be considered allowable temperature drains set by the manufacturer for each specific model. So, sewage pumping stations, into which warm, but not too hot, wastewater can be drained, are suitable for connecting to a shower cabin, bath, toilet bowl, bidet, kitchen sink etc.

However, if there is an automatic Washer, you should choose a model of a sewage pumping station for your home, into which you can drain wastewater with a temperature of 90 degrees or higher. It should be borne in mind that the mode of operation of such a technique usually involves boiling.

All this also applies to the dishwasher, from which an almost boiling liquid can flow into the drain. In addition to the current needs of the house, you should evaluate your plans so that you do not have to buy and install a new sewer station.

If you intend to purchase a dishwasher in the future, it is better to immediately choose a sewage pumping station designed for drains with a high temperature.

Pay attention to the number and location of the pipes. For every new household appliance that needs to be connected to, which may appear in the future, there must be a corresponding branch pipe. V otherwise it will simply have nowhere to connect.

Conclusions and useful video on the topic

An overview of the compact toilet waste station is presented here:

This video schematically shows the installation process of a large SPS:

A sewer station can dramatically improve your home's life. It is important to choose correct model SPS and install it correctly. Correct operation and regular maintenance will ensure that there are no problems with this useful device for many years.

Cities are developing rapidly industrial enterprises are equipped with new equipment, but problems persist. Therefore, it is necessary to design and install sewage pumping stations. The requirements for them are high, because a breakdown will provoke flooding of the nearest territories. It is necessary to accurately calculate the level of water supply, the type of pumps, as well as their number.

KNS level sensor controls. The flow should be determined based on the flow of water to the station.

b) Sewage pumping station 250 sanivort. Removes waste water from sinks below the sewer manifold. It is convenient to install it where there is no way to make the drainage system by gravity.

Complied with. The case material is safe, because it is plastic that is easy to clean. The pumping is controlled by a sensor. The station is equipped with ventilation.

c) Sewage pumping station sanivort 600 - pumps waste water containing faeces. Thanks to it, it is possible to organize the pumping of water in remote places. Nothing but feces and toilet paper must not be. Liquid temperature up to + 40C. The pumping of sewer stations is carried out quickly, because the power of the system is high - 600W. Up to 80 liters are pumped per minute.

The station is suitable for toilets, the outlet of which is horizontal, with a cask volume of at least 6 liters.

d) Sewer pumping grundfos stations easy to operate and do not require additional maintenance. Station pumps are well suited for high-pressure sewers. Additional control systems will ensure reliability and efficiency.

A modular pumping station is a complete factory readiness product. It includes fully assembled and finished equipment. Installation of a sewage pumping station depends on its purpose. The number of pumps is set on the basis of the same. A block-box is being constructed for the station in which it will be located. The design of pumping stations is carried out at the plant. They contain automatic system control. In the event of an accident or power outage, it will work in automatic mode for a long time.

Not suitable for domestic wastewater, its main purpose is to work with drinking water supply.

E) Fecal pumping stations - equipment that allows you to pump domestic wastewater, both in private houses and in microdistricts. When ordering, it is important to consider specifications... Stores often offer to choose on their own necessary equipment... You can get advice on it from the manager, This is a big plus for those who do not understand this.

The main factors affecting cost and performance are:

• collector depth
• length and diameter of the discharge manifold
• waste volume

The fecal station differs from the others in that the effluent liquid entering the system is not uniform in volume and time. Therefore, such reservoirs act as “sedimentation tanks”. They accumulate precipitation, emit bad smell... But the dangerous thing is that harmful gases accumulate. The main task of each tank is to create an environment for the normal operation of the pumps.

Modern pumping stations can be installed on new and old sewer systems.

Superficial sewer installation it is more powerful. After all, it is not limited in size, it can pump liquid in large volumes. These pumps are of two types - diesel and electric.

Is it possible to service the devices yourself

Many are worried about whether it is possible to carry out preventive work on their own. The answer is unequivocal no. Service of the KNS is carried out exclusively by specialists. Working mode. V service a number of planned mandatory activities are provided. So, for example, for use, baskets are installed to retain garbage. They need to be cleaned periodically. This can only be done by experienced people.

Modern diversion stations are now being produced. They are produced in modular version and are made of plastic. The plant is engaged in their manufacture.

WATCH THE VIDEO

Due to the plastic case, the weight of the station is small. Thereby assembly work are easier, and the service life of the products does not change. In complex stations, the equipment is housed inside. The construction of ground structures is no longer necessary.
