Pumping station for a private house: characteristics and instructions - Setafi

In this article, you will learn what a pumping station for a private house is, its purpose, device and principle of operation of a pumping station in a private house. And at the end of the article there will be top pumping stations for a private house.

Pumping station - what is it, its purpose. Water supply methods at home

Residents of private houses and summer cottages suffer from insufficient water supply. An autonomous system is not enough to provide a residential building, a vegetable garden, a garden. There are three ways to provide water to a room:

1. The pump is connected to the consumer
2. Storage tank and pump
3. Pumping station with hydraulic accumulator

In the first case, the pump pumps water from a source, but its power is often not enough, so such a system usually has low pressure.

In the second case, the pump pumps water from the source into a separate container, from where it is used by the consumer under pressure. The disadvantage of such systems is long-term operation.

We will analyze the third method in detail.

A pumping station is a complex of devices, a system for water supply to a room. The pumping station increases the pressure in the pipeline.

The design and principle of operation of the pumping station

A classic pumping station with a hydraulic accumulator consists of 5 parts:

• Hydraulic accumulator
• Centrifugal pump
• electric motor
• pressure gauge
• Pressure switch

In some models, an additional filter is installed to protect the device from sand, silt, rust and other contaminants.

The electric motor is connected directly to the pump by a shaft. The pump is connected by a pipeline to a water supply pipe, a water outlet pipe and a hydraulic accumulator. A manometer is also connected to the pipes to measure the pressure inside the pipes and a pressure switch.

How the pumping station works

The electric motor drives the pump. The pump pumps water from a source. Water fills the entire volume of the system - the internal volume of the pump, the pipes between the pump and the consumer, the internal volume of the accumulator. The hydraulic accumulator consists of a housing, an air area membrane and a water area. The liquid fills the internal volume of the accumulator by a third and begins to put pressure on the membrane, compressing the gas inside. The gas is pumped in at the plant. The gas itself presses on the water and tries to push it out. The pump pumps water all this time. To turn off the pump, a relay is installed in the station, it is installed near the motor and a water outlet pipe is led to it. The device consists of two springs / pistons, contacts, a membrane and a flange. The liquid fills the flange with the membrane and presses on the latter. When it presses hard enough on the membrane, the latter presses on the piston, which opens the contacts - electricity does not go to the motor, the pump stops pumping water.

You opened the tap - the accumulator membrane pushes water out, its amount in the system decreases, the pressure decreases. The liquid does not press enough on the relay membrane, the piston descends, and the contacts close - electricity is supplied to the motor, the pump turns on. It draws water from the source into the system until the pressure rises again to open the contacts.

Rating of the best pumping stations for the home with characteristics

1. Karcher BP5 Home

The first place is occupied by a model from the global German manufacturer - KARCHER. The device is distinguished by build quality, ease of use and ease of installation.
