The booster pump has found its wide application in many areas today. It is designed to increase the level of pressure in the water supply systems of industrial and residential buildings, including high-rise buildings that are built on hills. This is due to the fact that in such buildings the pressure level is not always sufficient.
Description
The equipment mentioned above is steam-oil units used to produce vacuum in order to solve various problems, among them:
- irrigation;
- firefighting;
- water supply;
- irrigation;
- water preparation in the device of fountains ;
- technological processes.
The plants have a compact design, which provides the possibility of their use in the modernization and construction of industrial facilities. At the same time, it is possible to reduce capital costs, installation area of technical equipment and operating costs.
Feature Reviews
The booster pump has a sealed housing in which the submersible pump installation is located. Such devices do not require centering, which is ensured by their design. Buyers emphasize that such devices have the appearance of lightweight pumps, if we compare them with traditional counterparts. This allows you to install them on the water supply, and installation can be done horizontally or vertically.
Consumers emphasize that such installations do not provide for constant monitoring and maintenance, because the system does not have oil seals. The booster pump has a submersible motor for the drive, which is highly efficient.
As for the hydraulic part, consumers emphasize that it is made of stainless steel, which is made using powder metallurgy technology. The system cools the water, which is pumped by the pump. The use of a standard engine and the presence of the frequency adjustment option reduce the level of energy consumption and the volume of membrane tanks.
Benefit Reviews
The booster pump, according to consumers, has many advantages, this is true if compared with traditional counterparts. For example, the tightness of this equipment is high, so the device is able to work continuously in emergency situations, which can not be said about console units. Customers also like the compact design, which allows to reduce the area for installation and capital costs, because the pump does not imply the construction of a solid foundation.
Devices are delivered ready for use, they are fully equipped. The consumer, in his words, has the opportunity to save money when installing the pipeline. The vacuum booster pump works silently, there is no vibration in it, which can be called an important advantage when used in public buildings.
Technical Specifications of a Horizontal Centrifugal Single Stage Booster Pump
Water booster pumps of the aforementioned type have a capacity of 450 m 3 / h. The cavitation reserve is 4 m, while the head reaches 53 m. The power consumption of this equipment option is 90 kW. The drive with the engine is carried out through an elastic coupling. The rotation speed reaches 1480 rpm. Power is 132 kW.
Principle of operation
The booster pump for high-rise buildings is a device that is ancillary equipment. It is used to increase the speed or strength of the main mechanism or machine. These settings can be steam or mechanical. The latter variety is a twin-rotor pump, in which there are rotating curly rotors. In the process, they enter each other and create a directed gas movement.
As for jet pumps, the principle of their operation is expressed in the fact that a directed jet of matter carries away gas molecules coming from the pumped volume. This equipment is used in systems to create a vacuum.
Among the main parameters, one can distinguish the limiting pressure; it can be achieved by equipment. Additional features are pumping speed, discharge pressure and allowable pressure, which is the greatest. The booster pump, the principle of which was described above, provides a vacuum in the range from 10.4 to 10.5 mm Hg. The pumping speed is 15 m 3 / s.
Description and characteristics of the pump Aquapro PMAP 6689
The Aquapro PMAP 6689 booster pump is an equipment whose price is 4200 rubles. This unit is necessary to increase pressure in domestic reverse osmosis systems. Suitable equipment for household systems that can be manufactured by different manufacturers. The kit comes with a power supply.
You can use this unit for installation in homes where the pressure in the water supply network is below 2.5 bar. Instruments are used for installation in a system that until this moment has not been supplemented with a boost pump. In addition, in order to re-equip the reverse osmosis system , it is recommended to stock up high pressure switches and low pressure switches.
The performance of this device is 2.5 l / min. Supply voltage is 220 V. Equipment is being manufactured in Taiwan. This pump can increase the inlet pressure in front of the diaphragm when an insufficient pressure level is noted in the water supply system. Among household reverse osmosis systems where this equipment can be installed, it should be noted those that are manufactured by the following manufacturers:
- "New water".
- "Geyser".
- Aquaphor.
- "Barrier".
What else you need to know about the principle of operation of the two-rotor booster pump
The gear transmission allows for the synchronization of routers with each other in booster pumps. If the gear ratio is constant, then large gas loads will cause the engine to work in overload mode, this will sooner or later lead to its failure. The gap then disappears over time, which is due to overheating of the rotors.
The rotors begin to touch the stator or each other, as a result of seizing or seizure. Therefore, in mechanical pumps, the speed will depend on the inlet pressure. For this, a rigid mechanical connection between the motor shaft and the rotor should be excluded. If we are talking about Japanese pumps, then this role is played by the magnetic coupling. The rotor levitates inside the chamber, and there is no mechanical connection between the rotor and the motor.
