Pumping station for the well: selection, installation and connection

The use of a pumping station in taking water from wells significantly increases the level of comfort of suburban life. The very process of filling containers for cooking and hygiene takes a few minutes and does not require the owners effortlessly. Do not you think that saving and power, and it is extremely useful?

All who strive for the effective portion of the arrangement, we offer thoroughly glean information. Here you will find information about what kind of a pumping station for the well will be the ideal solution. We'll show you how to perform the installation of the equipment and carry out the connection.

The article describes in detail the installation of water system, made on the basis of the pumping station. Thoroughly understand the nuances of the connection of the water supply and electrical parts. The proposal to review the information perfectly complement photo-collections, charts and video.

Pros and cons of the pumping station

In pumping station It has its advantages and disadvantages. First of all, it is very convenient - all the basic mechanisms are arranged in a single unit, and therefore easy to purchase, adjustment, installation, maintenance.

It requires a minimum of additional costs. The system has inherent immunity to liquid slugging - pressure spikes during opening and closing flow valve.

Only two cons, and both minor. Installing get noisy. Second relative negative - impossibility without additional water lifting mechanisms depths above 8-10 meters.

Noise is neutralized by the terms of installation and deployment. Lifting depth can be increased by introducing an additional device - ejector.

They are of two types. Built-in and external remote. Built-in offers more performance, but it increases the noise level of the whole structure. As already mentioned, this deficiency is treated by attention to the installation and placement.

The choice of power and models

Even a small and low-power installation is able to provide solid performance, sufficient to supply water to several consumers. To argue about the merits of one or another brand altogether useless - it's like to discuss cars. Each has its fans.

The main factor affecting performance is the amount of storage - the pump operates intermittently. Its task is to pump water into the hydraulic accumulatorAs soon as the pressure falls below a predetermined level.

But the water flow and pressure in the network already supports accumulator. Consequently, it is more than the volume, the less is triggered automatic, the lower the engine load launcher.

There still should be noted that half of the volume of the storage tank holds compressed air, which provides the system pressure and water displacement. Consequently, water is filled only a part of the tank volume. And, the pump switched off, the user can rely on it.

Required amount depends on many factors: the number of residents, the equipment installed and so on.

But schematically it looks like this:

• one or two people or cottage, where only one sink and a primitive shower - the volume of the accumulator 24 liters;
• three or four already have to look closely to the rate of 50 liters or more;
• More than 5 people - the minimum volume of 100 liters tank.

In addition to the performance features that are sure to be taken into account, there is an optional option. For example, the presence of dry run relay. It is not necessary to design, but is fully capable of under certain conditions, to extend the life of the station, or to prevent its damage. Unfortunately, it slightly increases the cost and complexity of the system.

Determination of the place of installation

Best lifting station positioned as close as possible to the point of collection. In this case the reduced inertia of the system. It reacts more quickly to the water flow, and quickly fills it.

That is the whole system works more smoothly, without pressure surges, more stable. So in an ideal world, the best solution is to install a pumping station in the well. It is not always possible.

Option # 1 - installation directly in the well

at Installation in a well It solved the problem of the removal of the source station. Noise mechanisms, too, does not affect the comfortable operation - the engine runs out of the living area.

There are also disadvantages. First of all improve the working conditions of mechanisms - primarily humidity. Measures for waterproofing and sealing units do not give the desired effect - due to condensation.

Mounting station within the well shaft can be performed in two ways:

• removable attachment with fastening of the upper surface of the well casing;
• wall bracket in the well bore.

Both methods are approximately equivalent. First a little easier, a second compact. Both of them interfere with other methods of lifting water - a bucket, for example, already manipulate inconvenient, but inevitable in this dripping water does not add to the life of the station.

In addition, the well will require insulation of the ground. Of course, the temperature of the water and the soil at a depth consistently above zero, but possibly superficial, local freezing and ice water - even for the pumping unit is completely contraindicated.

Option # 2 - caisson or a separate room

Yet there is the option to install a pumping station in the special service pit, dug in the ground, serving for water supply - this is called setting the caisson. The alternative is the installation of equipment in the ground premises.

Coffered mounting method has the same advantages as the plant directly into the well. Quiet, close to the point of abstraction, it is convenient. Most often, the caisson is mounted close to the maximum pit rings - at much less than the depth, of course.

Of the negative points worth noting the possibility of condensation. And the need for serious warming, With the most careful. And, if possible, the struggle with the condensate. It's all at the highest quality waterproofing - ground moisture in the caisson is not completely necessary.

Immediately mandatory measures to prevent falling into the caisson snow or rain - in most cases they solved hatch design. With the rest will have to tinker.

Construction ground utility room especially for pump station with very simple technology positions. But here we need insulation. And, since the location of the ground, you need to add insulation worries about heating. Freezing temperatures are not allowed in the room where the pumping station is mounted.

Option # 3 - inside the house

The third version of location - inside the house, which organized the water supply. Because of the noise of equipment is best to set it apart - usually used for this purpose the boiler room or cellar. But, in a space shortage, the installation can be carried out in the bathroom or laundry room, basement or under the stairs.

In any case, you should take care to soundproof. Otherwise, live in this house will be, to put it mildly, not very comfortable. And if you select a station setup in the basement, it is necessary to monitor the need for additional waterproofing. If the basement is wet.

When the pumping station is installed in the house, always remember about the removal from the supply well. This factor can also adjust the mount point has the inner geography of the house.

Requirements for installation of the main unit

Directly to the station itself, too, should be installed according to certain rules. She bolted to the ground. The base concrete is desirable. Allowed rigid steel frame from rolled sections. Its construction welded or bolted joints.

Very useful set for the laying of hard rubber plate - this will reduce the shock when the shock and reduce noise operation.

Much less frequently used for this purpose steel spring shock absorbers placed under the base of the type of fastening of the eccentric exciter vibration table.

But such an attachment, the slightest weakening or infringement of adjustment, is able to break the mounting socket on the basis station and create unnecessary burden on plumbing fittings - too large amplitude vibrations. So that the best option would be a hard rubber sheet having a thickness of up to 3 centimeters. The rigidity is about the same as that of a car tire tread year.

It is important to pay due attention to the electrical part. Be sure to connect the station to the body contour of the ground - regardless of the choice of the place of installation. Very useful RCD application (Tripping device - a second name of this mechanism "differential current device") - in particular if selected from the caisson installation or produced directly in the well.

In any case, the station should have a unique protective electric circuit - a minimum-automatic circuit breaker with a current response slightly above the nominal starting current setting.

In addition, the service life of electrical parts plant has a positive effect the presence of stabilizers, power strips, and uninterruptible power supplies. Maybe they are in the engine itself and not be able to have a significant impact, but such an addition will be very useful for electronics as part of automatic assembly station.

Construction of the water supply network

Technically, the connection to the well pumping station can be divided into two portions. Before and after the station. There is an important difference between them. Figuratively speaking the station - the sphere of influence of the pump directly.

After the station - already area of ​​concern accumulator tank, since it is responsible for the water flow and pressure build-up in the water system. Therefore, it is easier to consider separately. Especially because a variety of pipe can be used in them.

Fence of the water supply system

This part of the general scheme is between the pumping station and the well. That was happening to her water intake and power systems. The device is its simple, but there are a few important points.

Most often fence is HDPE pipe with a diameter of 32 mm. submission of such pipe section will not create extra loads on the pump. Plastic pipe is easier to tolerate freezing hammering. Not afraid of corrosion. Therefore preferable in this role. One end thereof is lowered into the water, connected to the second station.

From the water pipe is mounted on the clutch casing. It is screwed check valve that prevents flow of water to move back into the well. Thus, the valve prevents the emptying of the system - it is always packed.

On the valve must be screwed special tip-grid. The grid acts as a coarse filter to retain sand slurry, and the coarse fractions that can occur in water.

In most cases the inverse filter has a landing thread per inch. So this site will be required coupling with the transition 32 - 1RN.

Output pipe from the well is better on a level below the depth of soil freezing. It is possible to insulate the pipe and pass through the top, but it's better to put it to the house at depth. If this is not possible, then a heat-insulated shell is well supplemented by special electric heater pipe - it will prevent the water from freezing.

Lead pipe underground, at a depth below the freezing of the settlement. Most often it is the value of 1.4 - 1.8 meters. It may vary by region. Entering the house is better to produce at the same depth. If not, then it is sure to enter insulated, and very, very carefully. Insulation must begin again below the freezing depth.

When the lead pipe the trench, then before its fill soil, would be nice to fill it with sand. Sand layer does not give any serious advantages for drainage or things like that, but can later serve as a good indicator - the sand while digging will signal the proximity of the pipe.

supply pipe ends with crimp sleeve with the transition to inch thread to connect to the station. In this region a good idea to put one additional mesh filter (optional), and a collapsible fitting "an American". Longer necessary - it is necessary in the event of prevention or repair station. Valves and other water treatment systems in this area is not necessary.

Water pumping station after

Yield pumping station typically has a 1 inch thread. However, this diameter is not so important when installing the system - it can be easily shortened to half an inch. On the expenditure lines running longer pump and accumulator. Therefore, a possible increase in workload due to the smaller cross-section of the pipeline is not important.

So many Mounting give Threaded adapter with half inch - thus saving money for the further assembly of the system, since the smaller diameter pipe and fittings are cheaper.

In Fittings screwed shut-off ball valve in the event of maintenance and repair work on the system. Ball cock through collapsible "American woman" are already making out in the home water supply system. Its features already depend on which pipes are used in the building - polypropylene, or traditional metal-base metal pipes.

Immediately behind the shut-off ball cock incised and the flask with the water purification filter. To the station to put it impractical. He works better with a uniform stream of water, which is only possible after pumping station - on the supply line to the water station is moving too impulsive, with greater peak power. After the accumulator its motion more predictable and stable.

The filter must also be isolated from the crane system - in case of replacement. And then a good idea to provide a bypass pipe - in case this change for some reason delayed. Naturally, this bypass must also overlap. Otherwise, the water flow will always go through it - according to the rule of least resistance.

After the filter is already possible backbone branching - on cold and hot water, on the supply branch to the heating system and so on. Before removal filter can be made to the needs of irrigation area - the plants are not so demanding on the quality of water as a human being. For the other purposes it is better to let the prepared water.

filter characteristics depend on the characteristics of water in the well. They can be defined after the conclusion of the composition of water. Sometimes even more filters may be required - for example, anti-lime inclusions and ferrous compounds. Generic type does not exist in nature.

If only planned seasonal maintenance of water supply system (for example, in a country house), it is necessary to put the valve to drain the system. Usually it is a simple tap in the lowest point of it.

Start the station into operation and testing

Initial start up after installation or recovery of the system after a long "dry" simple, although it requires a specific manipulation. Its purpose - to fill the system with water before the first inclusion in the network.

It is a simple procedure that does not require special skills. The pump has a cork, which must be loosened. The hole is inserted a simple funnel and through which the fill system - it is important to fill the feed pipe and a pump with a pressure accumulator. At this stage, it takes a bit of patience - it is important not to leave air bubbles.

Pour the water to plug the neck, which is then rolled up again. Then a simple road manometer check the air pressure in the accumulator. The system is ready for launch.
