The sewer pumping station applies in cases where it is necessary to raise the sewage drain from the depth and send them to the main sewer. In this situation, the task was forced with the help of the KNS pumping the estates coming from the bath to central sewer. Initially, the customer wanted to put, but I had to dissuade him, because Topa will not work if there is no sufficient food for bacteria.

Real sewer pumping stations cost from 100 thousand rubles, we offered the customer a variant similar to the standard KNS and made non-standard. In the standard sewer pump station, 3 and more drainage fecal pumps with cutting mechanisms are installed. We installed one drainage pump with a knife inside the tube. Collector Well Alta Plast Tuba a good option For the organization of the CNS with their own hands. This tube is a model Alta Plast Tuba - 2.400, 2 meters high, in fact 210 cm with hermetic bottom and with a closing lid.

How to choose the sewer pumping station

So that the pumping station for your sewer is as efficient as possible, it is necessary to pick it up with it, guided by the criteria that we put out just below.

Choosing a station for your home, remember that the point of buying excessively powerful and, therefore, significantly more expensive equipment whose capabilities will be used by a third or even a quarter, is completely absent. The selected unit must be optimal and fully comply with the needs of your home. To this end, it is necessary to take into account the following parameters:

1. The distance to which the drains remains.
2. Maximum amount of processed wastewater.
3. The level of pollution of wastewater and their structural-quality composition. Thus, if there are large fractions in them, it makes sense to acquire such a KNS, which contains a grinder, which practically eliminating the probability of blockage.
4. The high-altitude difference is available between the station inlet and the place where the drains are served.
5. Dimensions of equipment.
6. Required cleaning level of wastewater.

Universal formulas used when calculating the performance of equipment, no. For this reason, the calculation algorithm should be used, which, as a rule, is presented in the instructions attached to a specific CNF.

The calculation of the necessary performance of the station is performed in the following sequence:

• the daily flow consumption of water in the house and the volume of waste genera are determined;
• it is based on an estimated flow of flow income on the daily period;
• the maximum and minimum sewage stream values \u200b\u200bare calculated;
• the necessary productivity of the pumping station is determined, taking into account pollution of the effluent.

Correctly determining the parameters listed above, you can unmistakably choose the optimal equipment that will fully satisfy the needs of your home.

We have already spoken somewhat higher about the size of prices for sewer pumping stations. Now we want to clarify that the price is quite an eloquent indicator:

• brand popularity;
• maintainability of the product;
• capabilities service equipment.

Preferred cheap aggregates should not if the operation will be daily and if there is no additional pump equipment For evacuation and drain and no backup containers are provided.

How to install the KNS.

To begin with, we deliver the necessary materials for installation and tools to the installation site. We start digging the pit under the CNS and ...

In parallel, install the rosette inside the tube to supply the power pump. The hole is drilled by the hole and the cable in the corrugation is done. The cable is mounted to the outlet, and the socket screws on the screws to the walls of the tube.

The discharge tube is already in the trench and launched into the central sewer, it remained to connect it with the station. Copper kitty for installation of the sewer pumping sone.

When dripped up to the necessary depth, in our case it is 225 cm, we make a sandy pillow and equalize the bottom of the pit. We lay guides to lower the ZBB plate.

By this time we are brought reinforced concrete slabWith the help of which we will yield our asthgregat. Since the crane-board courtyard could not physically come in physically, we were transported by a manually to the meters for 3.

The reinforced concrete slab on the spot, you can begin to lower the tuba in the pit.

A good tube is even the fact that it is light as it consists only of plastic, we easily lowered it and installed in place. Next, using a rope tube was securely fixed to the ZhB plate. Now you can start the discharge pipe (PND 32) and start to bury.

A tube is buried, of course sand, so that the backfall was dense. The electric cable in the trench is stacked.

For inserting underwear sewer pipe It took the station to drill the hole under the blade of the jigsaw and himself. A circle was carved and started with a rubber seal.

It remains only to bury ...

honestaying the incoming drains.

KNS closed with a lid.

The discharge pipe of the PND 32 in the house is started in 50 sewer gray pipe through a transitional gum providing reliable fastening and tightness.

In general, the customer was pleased with the work done, and promised to recommend us to his friends.

This instruction is suitable for all CNS housings (polyethylene, fiberglass) underground

See typical projects and CNS schemes

Before installing the CNS, it is necessary to properly prepare the basis. When developing a soil with a mechanized manner, with the help of an excavator, the drill must be a bit not finalized to the project mark, in order not to violate the natural integrity of the soil. The refinement of the soil to the project mark must be done manually, not allowing perk concrete base Under the KNS 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, throughout the perimeter, is done sand pillow 200 mm height with watering with water and rubbing. On the developed drawings is going to formwork for reinforced concrete base. The formwork is mounted several layers of grid made from the reinforcement of various diameters and a different grid step (as a rule, the grid is made in increments of 100x100 mm from the reinforcement Ø 10-12 mm, 2-3 layers depending on the height of the concrete base and the size of this base). The sizes of base under the CNS are developed by project organizations, depending on the size of sewage pumping stations, the composition of the soil at the installation site of the KNS and the presence groundwater At the installation site. Next, the formwork is poured with concrete and give it to settle. In various cases use various brands concrete. In dry soils, M150 brands are used, and in the implanted soils, moisture-proof brands of hydraulic concrete M200, M 250 Concrete works It is necessary to follow all the rules of concrete work technology.
3. After the concrete gains strength, the installation of the CNS body begins. Before mounting the CNS housing on the base, clean the surface from foreign objects.
4. When the housing is lowered into the housing, the load from the mass of the housing is uniformly in all mounting hinges.
5. The plastic housing must be mounted strictly in the project position. After the case was installed on the project mark, it is necessary to make sure that it has no damage and is installed strictly according to the project axes. Check the vertical of the housing. When the horizontal foundation of the KNS will stand vertically.
6. After installing the KNS on the concrete base, in the pump station skirt, the holes (8-12 pieces are 8-12, depending on the station diameter) with a diameter of 12-16 mm, long 18-22 mm) for the installation of anchor bolts. After that, the bolts are inserted into the holes, clogged and delay.
7. For high level Groundwater in addition to the attachment of the KNS anchor bolts, to a concrete base, the lower part of the KNS is needed, approximately 0.5-0.8 m to fill with concrete. Calculation of the weight of concrete is made in the scope of a working draft or project production project.
8. After attaching the KNS to the concrete base, the backfill is made of sand, layerly with a tuckling and watering water to the level of the supply and pressure collectors. Before the backfill, make sure that the CNS body has no damage. After installing the KNS on the basis and check of its verticality, start the back of the back. (Sand backflow serves as a gasket between the CNS housing and untouched ground and serves as the KNS protection from the soil movement).

1. Then there is a connection of the pipes of the incoming manifold and the addition of pipes of the pressure branch. Soil under the underwater and pressure collector tamper.
2. Then the inverse flow of sand is made in the layer, to the ground level with layer-by-layer rambling, evenly throughout the diameter of the KNS. In case of non-compliance with these conditions, the hull or neck is possible.
3. Then the pumps are installed in the CNS housing. The lowering of the pumps on the CHS guides can be done manually (if the pumps have a small mass) or with lifting devices Type tale or cranes (if the pumps have a large mass).
4. Then mounted. The pump control cabinet, according to the project, can be placed on the CNS housing in a special metal box (protection against vandals), near the KNS in a metal box or in any room that are close to the CNS. All are easier and cheaper to place the pump control panel on the CNS housing. On our production, we have developed areas with hermetic inputs in the KNS, to install metal boxes within which pump control cabinets are located. Electrical cables The pumps in the standard have a length of 10 meters and if the pump control cabinet is not located near the KNS, then it is necessary to buy an imported, expensive cable for increasing, which increases the cost of installation of the KNS.
5. The next step is made by the central cable to the pump control panel. The cable is selected depending on the power of the pumps and according to the installation of the KNS.
6. Then inside the KNS hosted suspended floats for pump operation.

At the final installation of the KNS - connected cables from pumps, from floats, from overflow sensors, etc. To the pump control panel and the commissioning of the KNS is made.

The overall concept of the sewer pumping station

The main purpose of the sewer pumping station is to dismiss the sewer water of stock or commercial destination. By design, sewer pumping stations are distinguished, medium and complex.

The sewer pumping station consists of a hermetic capacity to which a fecal pump is connected. The main function of the pump is the pumping of sewage waste into another sewer station or to the recycling places.

Sewage pumping station Photo:

The sewer station consists of:

• polypropylene tank;
• submersible pumps;
• pipelines;
• pressure and discharge nozzles;
• automation systems;
• ventilation systems.

Additionally, installation is possible:

• double reinforced bottom;
• thermal insulation;
• check valves;
• valves;
• service platforms;
• control shield;
• locking hatch;
• control sensor;
• selection of case material.

To maintain the KNS, set the staircase and equip the platform inside the tank. Hatches are designed to close the stacks of the station to protect external environment From smell.

The principle of operation of the KNS is that the sewage waters come to the KNS through the pipeline and fall to pumps. In the pipes installed check valves that prevent the return of wastewater into the system. Through the pumps are pumped for processing.

The main functions and varieties of the CNS

The main function sewage station is a forced pumping of stock and sewer water.

If complex embossed areas do not allow to equip the sample drain, so as not to install deep collectors, it is better to purchase a sewer pumping station.

In accordance with the pumped liquid allocate:

• sewage pumping stations of productive drains;
• sewer pumping stations of household flow;
• CNS storm flow;
• CNS sedimental runoff.

In accordance with the scope of application allocate:

• sewer pumping stations for home;
• sewage stations of industrial type.

In accordance with the power, sewer pumping stations share:

1. Mini-sewer stations are a small hermetic container connected to the toilet, right in the toilet or in the bathroom. Such sewer pumping stations are produced in various forms, color I. designer decisions. The package of a mini-sewer pumping station includes a fecal-submersible type pump, which is equipped with cutting mechanisms. The pump power is not more than 400 W.

2. Average sewage pumping stations that differ are very popular. wide spectrum models. Such a station includes a polymer tank, which is installed in the ground, and the pump. The scope of application of medium sewer stations both household and industrial. In the household sphere, one or two pumps are used, and in industrial - only two. Pumps are used diverse: from models with elements that carry out multichannel cutting operations for the processing of wastewater, up to closed single-channel operating wheels. In industrial sewer pumping stations, the first type of pumps are not installed, because the cutting models have instability to stones or other strong objects. If the hardware falls on the knives of the cutting mechanism - the pump will break immediately. This is a significant disadvantage of this type of pump.

3. Large sewer pumping stations are used in urban sewage and drain systems. IN large systems Set the powerful pumps from a multichannel type with the presence of working wheels. Pumps with the presence of a cutting mechanism in large stations are not used.

When choosing a sewer pumping station, take into account:

• depth of the underwear system;
• type and amount of fluid that should be accepted;
• varieties of pumps;
• method of managing the CNS;
• materials from which the CNS is made;
• diameter of the body of the sewer pumping station;
• power of the CNS.

Sewer pumping stations are made of polypropylene, reinforced fiberglass and polyethylene. These materials ensure the protection of the station from corrosion and other external influences.

Pay attention to the internal parts of the KNS, better if they are made of stainless steel. In seismic areas, you need to install sewer pumping stations with a superproof case. In the northern regions it is necessary to conduct additional insulation KNS.

Take care of the installation of vibration and leakage sensors on the pump.

The presence of an automatic control system will allow you to regulate the operation of the pump and organizes uninterrupted work Stations.

Installation of the submersible fecal pump

Kit for installing a submersible fecal pump in the KNS

1. Automatic system The compounds of the fecal pump - is a pipe clutch, one part of which is mounted for the bottom of the tank of the sewer pumping station, and the second part to the fecal Naos, allowing you to remove the fecal pump from the well.
2. Guide pipes are the rails on which the fecal pump is mounted and dismantled in the sewer pumping station.
3. The drain chain is necessary to raise the fecal pump from the bottom of the well.
4. The connection of the pressure manifold is selected depending on the selected material of the fecal pump strapping ( metal pipes, polymer pipes).
5. Threaded or flange compound with check valve fecal pump.
6. Check valve, which cuts off the inverse flow of fecal drains into the sewer pumping station.
7. The catch - will help to overlap the pressure pipeline, in the case of dismantling the fecal pump from the sewer pumping station.
8. The insertion in the pressure collector is selected depending on the type of pipe.

Installation of a fecal pump in the sewer pump station KNS

Gently mount the automatic connection system at the bottom of the sewer pumping station. To the opposite part we attach the fecal pump. We set the guides along the walls of the team well. Now from the automatic clutch, we send a pressure collector to which fastened check valve and valve.

We proceed to the installation of the electrical part of the sewer pumping station. Exhibit float sensors inside the sewer pumping station tank to provide automatic work Fecal pump, and plug them to the control cabinet. We connect the fecal pump to the control cabinet and the control cabinet itself of the sewer pumping station to the power line, it is desirable to secure faecal pumps from voltage jumps using a voltage stabilizer and special filters.

We dress the flow chain on the fecal pump, and omit it on the guides at the bottom of the sewer pumping station. Automatic connection system will provide sealed connectionDue to the mass of the fecal pump that gives pressure on the pressure sewer.

It remains only to press the start on the control of the sewer pumping station and run the fecal pumps into operation.

the floor, but if it is the average, size, the equipment, then it will make a pick-up or it will be necessary to post in a special room of the KNS.

Today we will sharpen attention to the arrangement of the pit, including all regulatory components, namely:

Sanitary - protective zone of the KNS, which should be respected within the established standards (about 15 m).

Requirements for the fencing of the CNS, if it is bueled, can be observed, clean, due to the safety or safety of equipment, and so put the lock on the closet and the hatch, and that's it.

Comply with the safety regulations, and therefore, during the construction of the pipeline and the pit, in order to avoid traumatic situations, it is necessary to build the barriers of the working part.

At the installation of the CNS, the estimate should include all alleged expenses:

• for rent special equipment for digging and equipment installation;
• on the purchase and delivery of sand with concrete for the foundation of the CNS;
• on concomitant tools and parts for fasteners of the tank;
• to pay for the work of a team of workers, if you do not plan to install the sewer pumping station with your own hands, etc.

And so, you took into account all the above and ready to start the installation itself:

• Harvested, in its size, superior dimensions of the KNS design. This is necessary for conveniently connecting the rest of the pipeline and power supply.
• In order not to make the soil sink, the lowest part of the pit is digging into the manual.
• According to the drawing, the formwork is built: a sand pillow is made (10 - 15 cm), the fittings are installed and is filled with concrete into several layers, using the level, in order to make the foundation as much as possible.
• Only after complete hardening of construction, the housing is attached to it, given that when installing the KNS, the deviation values \u200b\u200bfrom the verticality are permissible in the range of 5 mm.
• It should be verified that inside the tank there is no garbage and water.

Water should be pump out, and not pour, tipping the case.

• With the possible appearance of groundwater, the design is fixed with anchor bolts, and then they are poured over the top of the commodity concrete so that the top of the concrete plane exceeds the lower edge of the equipment.
• After all manipulations, the backstage is performed up to two collectors: pressure and self-reading.
• Then the power supply and pipeline are fed.

The inverse backfill is carried out evenly around the circumference of the KNS, selecting the stones and the tamping layers of 50 cm, with a plus temperature, by pouring water. IN winter time Note that it is impossible to freeze the soil.

The cover, ventilation, etc., attached to the items available in a set.
