Description:
Statistics show that residents of private and apartment buildings have to deal with such problems as low pressure in the network of cold water. Lowering the water pressure in domestic water systems affects not only the comfort of shelter, but also fraught with failures washers, dishwashers, shower, electric and gas water heaters and miscellaneous equipment. How to solve this problem? Let's try to answer in order ... In this situation, the best and sometimes the only option is the use of domestic pump pressure increase. These compact devices are designed for a small increase in pressure in the existing water supply system, for example, in front of the instantaneous water heaters, washing or dishwasher.
In most cases, for these purposes are used pumps GRUNDFOS series UPA. Units have small dimensions and low weight. Design inlets "in line" makes it possible to assemble them directly on the pipeline.
Just pumps Kiev have several modes, which are selected by switches. In this case, the toggle switch has three positions - "Off", "MANUAL" and "Automatic". Manual mode of work awaits the functioning of the pump only when it made vosstrebovannost. If you choose this option, you need to be sure that water flows smoothly into the pump and open valve at water pumping. Failure to comply with these conditions may cause the output device failure.
More optimal mode of operation of the pump, requiring no control over his work from the owner, there is an automatic mode. With its built-in instrument design sensors pump is switched on auto-matically as soon as the open valve at water pumping or valve feeding water into household appliance (if the water consumption will be more 90-120 l / h). The pump is also automatically turned off with decreasing flow below these values (the crane at water pumping covered or closed entirely), and as if the flow of water in the pump inlet will be terminated. That is, provided another important function - protecting the pump from the "dry run".
If you need the pump is no longer the switch set to "OFF". In this situation, the presence of liquid water indiscriminately freely flows through the pump. The design of these pumps is quite simple and hence reliable. It consists of a body, which houses the rotor mounted on its rotor. At the time, too, so called "wet-rotor" is separated from the stator protective sleeve made of stainless steel. Such a design provides cooling working pump pumping water, and also protection of its electrical parts from moisture. The devices consume little power and virtually silent (noise level - 35 dB), which allows for their installation in any room of the house.
To increase the pressure in the water supply system can be another way, though this requires considerable cost and time. But the reliability of such a system will be higher. For these purposes in an apartment set the desired level of capacity, which will meet drinking water. Capacity will be filled automatically by the float valve. Next to the capacity of the pump is installed (with other pumps - here). The water from the reservoir, the pipeline, the post-Paeth in pump suction branch, then under the pressure created by pump all points water pumping.
