Pumping unit for raising water pressure for the home: installation

With the onset of spring depending on the localitywater pressure in the water supply system of residential buildings is significantly reduced. This common problem always requires a solution. You can demand the necessary pressure from the municipal service, but for many reasons it is almost always impossible. Often in such situations, a conventional pressure boosting plant is used. The purchase of these devices can be paid individually or by all residents of the apartment building. It is always possible to install pressure boosters on your own.

Pump functions

Special installations that increase pressure,serve to stabilize the work of plumbing. The list of pump functions includes water supply for irrigation facilities, pumping of liquids, circulation in a variety of technological processes. Also tasks are being carried out to increase pressure in fire fighting systems, engineering structures for cold and hot water supply.

In some cases, low head pressure does not givePossibility to use household appliances in a private house, office or apartment. In such a situation, the installation of pressure increase in the water supply system will be simply irreplaceable.

Available Models

The widest range of imported anddomestic up-grading pumps can be classified according to a number of main features. Devices can have an automatic or manual trigger mode. By type of construction, centrifugal and "in-line" pumps are distinguished. Such devices differ in the horizontal or vertical direction of rotation of the axis in the working system.

Pumps of the brand Grundfos

In many countries, these pumps are veryhigh demand. The products of the famous Danish concert with a flow sensor and wet rotor are cast iron UPA 15-90, as well as UPA 15-90N with anti-corrosion coating. The settings have always been compact in size. The power of such pumps is small, they almost do not create noise and are made only from high-quality materials. The installation of water pressure increase due to such characteristics occupies leading positions among existing manufacturers of similar equipment. The housing has a special switch that allows the pump to be switched from manual to automatic operation.

WILO products

Manufacturer specializes in pumpsa variety of applications and produces such installations with wet rotors and flow sensors such as PB400EA, PBH089EA, PB201EA and PB088EA in a cast iron housing. Several advantages of the units can be distinguished: high corrosion resistance, noiseless operation, relatively low power consumption, low weight and compactness, thermal protection system, easy mounting with nuts for fastening.

Pressure Waste Pumping Unit Wester

Most often used in the design of systemswater supply for cottages, houses, individual apartments, small offices. Installed anywhere on the pipeline. These pumps can operate in different modes. A special switch is installed on the terminal block.

After selecting a certain position, the installationIncrease the water pressure will work in one of several modes. This can be a permanent action, which does not provide protection against dry running. The pump can be switched off, but the water will still flow through it to the consumer. The device can automatically turn off when there is no liquid and operate at a flow rate of more than 0.033 liters per second.

Recommendations for choosing a pump

When choosing the right unit,attention to the maximum flow, head and power, the operating temperature range in which the pressure boosting unit functions normally, as well as the noise level. The price of pumps can depend on the brand, the performance, materials and technologies used in the manufacture. You can buy high-quality and compact units at an affordable price at special trading floors where construction materials are sold, in online stores with a fairly wide range of similar devices, as well as in stores selling sanitaryware. On the sites you can get acquainted with the technical characteristics of such pumps, see attached photos, and compare prices for a particular model, as well as get advice from a qualified manager.

Possibilities of using pumping stations

Often pumps are used to assemble a systemglaze. In the simplest mechanisms, where only the supply of water is needed, there is no need for additional devices. Automatic control of the pressure increase in such cases is not required.

In some buildings, water supply systems are installed from wells. Such pumping stations always maintain the necessary pressure, shutting down and turning on automatically.

A multi-pump pressurization unit canUse with insufficient pressure of water in the main pipelines. In combination with such devices, intermediate storage tanks are often installed. Pumping stations are not recommended to be connected to main water pipes directly because there is a risk of idle mechanisms due to lack of guarantees of continuous water supply or exceeding of permissible pressure values.

Basic components in water supply systems

A pressure boosting device for a home canconsist of a pressure switch, a hydraulic accumulator, as well as control and connecting equipment. Pumping stations are functionally characterized by the ability to constantly maintain the necessary pressure in water supply systems and automatically regulate their own work, depending on the use of water in the building.

Hydroaccumulators are reservoirsof metal with a special inner rubber membrane and air pumped pre-pressurized through a nipple located under a plastic lid.

The pressure switches areelectromechanical devices that react to internal pressure in water supply systems, and the opening or closing circuits, depending on the head. The settings of this device can be adjusted.

The principle of operation of pumping stations

When the pump station starts working, the installationIncrease of pressure is automatically activated and starts pumping water to consumers. After the valve is closed, the accumulator is filled, expanding the membrane and increasing the pressure in the water supply system. After reaching the preset pressure level, the relay switches off the pump. When the crane opens, the accumulator supplies the user with water under pressure. The pressure in the system will decrease and the pump will not be activated until a certain time. The relay turns on the pump again as soon as the head drops to a certain level.

Causes of pressure loss

With the change of the season there are not onlychanges in the temperature of the medium, but also pressure in the water supply networks. This phenomenon is caused by several reasons: the first is an illiterate miscalculation of water supply systems in the design process, determination of the required diameter of the water pipe, the required capacity of the pumping stations, the average daily and average hourly water flow. For this, it is necessary to take into account the terrain, number and population growth for the year, the length of the networks and other factors.

Installation of the pumping station

For normal operation of each installation,the correct selection of the required diameter of the suction pipe is important. The most suitable for this are flexible, non-reinforced reinforced hoses, as well as plastic or rigid metal products. When installing the suction pipe, sharp expansions, constrictions and turns must be avoided.

A permanentslope of the pipe from the installation to the source of water intake to avoid the formation of air congestion or the accumulation of bubbles. To facilitate the filling of the suction line and the pump before starting, as well as to prevent leakage from the system when the mechanism is shut off, check valves with a special screen filter are usually installed on the suction pipes. The instructions for dismantling the pressurization unit require the preliminary evacuation of water from the system and the subsequent disconnection of all components.

Pressure line

To pressure mechanisms such strict requirements are notare presented. Naturally, the diameter of the pipes without need not better not to narrow, so as not to create an additional loss of productivity and pressure when supplying water to consumers.

Conclusion

Technique makes life much easier for a person. The operation of many devices in the farm is connected with the supply of water. Pumping unit pressure increase is the most optimal choice in the matter of ensuring the normal functioning of household appliances. These devices are widely used today in agriculture, in the design of domestic water supply systems or in extinguishing fires. To select such equipment correctly, it is necessary to determine its intended purpose and the necessary technical characteristics.
