A high-pressure water pump will become an alternative source of water supply in homes or in dachas where there is no centralized water supply or pressure problems, which makes water entry difficult.
Types of water pumps
Depending on the purpose of the water pumps are:
- water-lifting - they are used to supply water to the water supply system;
- circulation - designed to circulate water through an autonomous heating system.
- drainage - will help to pump out liquid after a rain, to clear sewage drains.
Water-lifting water pumps are divided into the following types:
- Centrifugal water pumps of high pressure. In these devices, the water head and its movement arise due to the formation of a centrifugal force when the impeller blades rotate. The blades push the liquid against the walls of the hull, water under pressure is pushed into the pipeline. Such types of pumps are best installed in enclosed spaces, it is important that they are protected from rain. Centrifugal devices have a number of advantages, namely: the implementation of a continuous supply of water under pressure, reliability, low cost, easy operation. The disadvantages include the need to fill the housing with water when the pump is started.
- High-pressure vortex water pumps. The principle of operation of the devices is the rotation of the vortex wheel, during which water penetrates into the cavity inside the housing, and then is pushed out of it. The advantages of the pump include a high capacity for absorption. It should be borne in mind that care should be taken when pumping water from contaminated sources.
- Electromagnetic high pressure pumps. Their work is based on the action of an electromagnet, which is the main element. It attracts the anchor when the AC voltage is applied to the windings. During the change of polarity, the anchor assumes its former position. Because of vibrations, water fluctuations start with the expulsion of excess water through the valve into the discharge nozzle.
Depending on the power source, the pumps are:
- high-pressure liquid water pumps - contain an internal combustion engine, so that the pumps can operate autonomously. As a fuel, use gasoline or diesel fuel;
- electric high-pressure water pumps - operate only from the mains. They can be two-phase or three-phase.
Orienting in the characteristics and principles of the devices, you can select a high-pressure water pump for the house.
