Pumping station for a private house

Water supply problems are faced by many private households. Many houses are built or are being built in places where there is no centralized water supply. These are holiday villages, cottage towns, small towns and villages.

If the house is in such a place, then the solution to the water supply problem lies entirely with the owner. One of the solutions to this problem will be the installation of a pumping station. It will ensure stable water pressure in the water supply system, and its supply to all points of water intake.

More recently, the main way to supply water to the house was to use a submerged pump. It was installed in a well or well. He began to work at the moment when the tap opened in the house. Such a system was notable for its instability in operation. Stability was affected by voltage drops, a decrease in the water level in a well or well.

This caused a widespread transition to pumping stations. In the pumping station, a special reservoir is added to the pump, which plays the role of a hydraulic accumulator. It stores a reserve supply of water, which makes it possible to use water at a time when it is impossible to draw water from the well.

A surface pump is used in pumping wells, which makes it possible to use small diameter wells. For a full supply of the average house, it is enough to use a pipe or a hose of an inch diameter.

Components

At first glance, the pumping station is not a complicated mechanism. It consists of an electric motor, a surface pump, a hydraulic accumulator, an automatic control system.

Hydraulic accumulators are divided into two types: the first is a tank, and the second is a battery. In their coordinated work, they provide an uninterrupted supply of water to the inhabitants of the house. The pump pumps water from the source, and delivers it to the water supply system of the house.

The hydraulic accumulator helps maintain a constant water pressure in the system, and the automatic control system allows you to do all this in automatic mode.

Using a tank as a hygro-drive, this is an obsolete design. The principle of its operation is based on pumping water from a source into a container located on the upper floors, or in the attic. Water pumped into the tank flows by gravity to the daughters of water distribution. In the tank there is a float control system for the pump engine.

When the water level drops, a float signal is triggered, including the pump motor. The pump turns on, filling the water level in the tank until the upper float signal is turned on.

Such a system has good energy efficiency. It does not turn on the engine every time the crane is opened. Suitable for low flow wells. The biggest drawback is the possibility of a flood. The tank is located on the top floor or attic, in case of leakage it can flood the entire house.

Relay, controls the air pressure in the accumulator. When a certain value is reached, it turns off the pump. Then it turns on when the pressure reaches a certain level. When the water flow is small, then the pump is turned on less times.

Advantages and disadvantages

The main advantage of the pumping station - in the absence of the need to dig a well, or an artesian well. The surface pump is capable of pumping water from a depth of up to 8 meters with a small diameter hose. If the groundwater depth is below 8 meters, then you can use a pump station with an ejector. It works on the principle of discharged air. And it can get water from 30 meter depth.

The disadvantages include the fact that there are limitations in depth, stations with an ejector have a high cost, they are very noisy during operation. They must be installed in a separate room. The temperature in the room where the equipment is installed must be above zero degrees. It is necessary to constantly check the operation of automation.

Criterias of choice

Having decided to install a pumping station in their home, many do not know how to make the right choice. Such mechanisms have a large number of characteristics, and they must be considered with one complex.

Power

This parameter affects how much water you can get at the same time for all consumers in the house. How far can the well be from home? At what depth is the water-bearing layer located?

Also, when choosing power, one must take into account the productivity of the well.

The pump will pump out water faster than it will come. All these data are indicated in the passport of the well, and the pumping station. An average private house will be able to serve a pumping station with a capacity of 1000-1500 watts. It will provide a capacity of 4000-6000 liters / hour.

Storage tank

The storage tank is designed to receive a supply of water in the event of a power outage, or a drop in the water level in the well. Here the choice is influenced by the water needs of the family for a certain period of time. The tank should satisfy all your needs in terms of volume. The material used is plastic, steel, cast iron.

Many have bias against plastic. This is the cheapest material, it is considered the most unreliable. In the event of a crack, there is a chance to fill the entire house with water.

Steel tanks are reliable but corrosion resistant. Cast iron is the most reliable, but heavy. In good circumstances, they will last a long time. The hydraulic accumulator comes complete with a pump; it usually has a small volume not exceeding 50 liters.

Installation Protection

Pumping station - This is a mechanical product that needs some kind of protection. First of all, it is overheating. During prolonged operation, overheating of the motor may occur, which may damage it.

Secondly, it is protection against dry running. If there is no water in the supply, the pump must shut off. Otherwise, there will be excess air pressure in the system, which can lead to breakdown of the pump, and violation of the sealing of some components. Such protection can greatly affect the cost of the pumping station, but it's worth it.

Control system

Two control systems are applied - manual and automatic. All the difference is that the automatic system itself pumps water into the tank when it is empty. In manual mode, this will need to be done independently. Manual, optimally set in the place where they come very rarely. In a normal residential building, it is better to set the automation.

If your area often loses electricity, or a water level drops in the well, then you will need to take appropriate measures. To buy an electric generator for electricity, and a storage tank for water.

Installation and operation

Connection diagram of the pumping station:

It all starts with the selection of a pumping unit with the necessary parameters. Next, the installation of the necessary pipe structures takes place. When everything is connected, a test run is carried out, and, if necessary, regulation and adjustment of automation. Further, everything is transferred to operation.

All these works are best trusted by specialists. During operation, it is important to remember to periodically inspect and operate. In particular, the deposition of salts on the pump parts and the sensors used may depend on the quality of the water, which can lead to malfunctions.

Not all problems with water supply caused by a malfunction of the pumping station. Some of the problems can be hidden in pipes, or in a well. As for the problems of the station itself, it is better to contact specialists. If this is not possible, then it should be remembered that the main problems are related to mechanics and sensors.

Price and manufacturers

There are many different pump station offers on the market. Economy options start at an average of 6,000 rubles. It is worth noting that for carrying water into the house, the cost of pipes, hoses, and other necessary parts must be added to this amount. The cost, first of all, is influenced by the capacity of the installation, and the size of the capacity of the accumulator. A significant role in the price can have a manufacturer’s brand.

In the Russian market, preference is given to manufacturers from Italy and Germany. They are distinguished by their high quality and service. Recently, foreign companies are slowly pushing back domestic manufacturers.

Upon final selection, find out about after-sales service. Pumping stations sometimes break down. Therefore, it is better to have the company's products that will help eliminate the malfunction.
