Booster pump today found its wideapplication in many areas. It is designed to increase the level of pressure in the water supply systems of industrial and residential buildings, including high-rise buildings, which are built on the hills. This is due to the fact that in such buildings not always the level of pressure is sufficient.
Description
The equipment mentioned above is a steam-oil unit used for obtaining vacuum for the purpose of solving various problems, among them:
- irrigation;
- firefighting;
- water supply;
- irrigation;
- preparation of water in the device of fountains;
- technological processes.
The units have a compact design thatprovides 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 areas for technical equipment and operating costs.
Reviews about features
The booster pump has a sealed housing, inwhich is a submersible electropump. Such devices do not require the need for alignment, which is ensured by their design. Buyers emphasize that such devices are kind of lightweight pumps, if you compare them with traditional counterparts. This allows them to be installed on the water pipe, and the installation can be done horizontally or vertically.
Consumers emphasize that such installations do notprovide for constant monitoring and maintenance, because the system does not have oil seals. The booster pump has a submersible motor for a drive that is highly efficient.
As for the hydraulic part, the consumersemphasize that it is made of stainless steel, which is made using the technology of powder metallurgy. Cools the system with water, which pumps the pump. The use of a standard motor and the presence of a frequency adjustment option reduces the level of power consumption and the volume of the membrane tanks.
Feedback on benefits
Booster pump, according to consumers, hasmany advantages, this is true if we compare with traditional analogues. 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. Buyers also like the compactness of the design, which allows you to reduce the area for installation and capital costs, because the pump does not involve the erection of a solid foundation.
The devices are supplied ready for use, they arefully staffed. The consumer, from his words, it becomes possible to save money when installing the pipeline. The vacuum booster pump works noiselessly, it lacks vibration, which can be called an important advantage when used in public premises.
Technical characteristics of horizontal centrifugal single-stage booster pump
Booster pumps of water of the above type have a capacity of 450 m3/ h.The cavity stock is 4 m, while the head reaches 53 m. The power consumption for this variant of the equipment is 90 kW. The drive with the motor is carried out through an elastic clutch. The speed of rotation reaches 1480 rpm. The power is 132 kW.
Principle of operation
A booster pump for a multi-storey building representsa device that is an auxiliary equipment. It is used to increase the speed or strength of the action of the main mechanism or machine. These units can be steam or mechanical. The latter is a two-rotor pump, in which there are rotating curly rotors. In the process of work, they enter into each other and create a directed movement of gas.
As for jet pumps, the principle of theirof the work is expressed in the fact that a directed jet of matter entrains the molecules of gas coming from the pumped volume. This equipment is used in vacuum systems.
Among the main parameters can be identifiedlimit pressure, it can be reached by equipment. Additional features are pumping speed, outlet pressure and permissible pressure, which is the greatest. The booster pump, the principle of operation of which has been described above, provides a vacuum in the range of 10.4 to 10.5 mm Hg. Pumping speed is 15 m3/from.
Description and characteristics of the Aquapro PMAP 6689 pump
Booster pump Aquapro PMAP 6689 representsequipment, the price of which is 4200 rubles. This unit is necessary to increase the pressure in domestic reverse osmosis systems. Suitable equipment for household systems, which can be manufactured by different manufacturers. A power supply is supplied.
Use this unit for installation inhouses where the pressure in the water supply system is below 2.5 bar. Devices are used for installation in the system, which until this point has not been supplemented by a boost pump. In addition, in order to re-equip the reverse osmosis system, it is recommended to stock up the high and low pressure switch.
The performance of this device is2.5 l / min. The supply voltage is 220 V. Equipment is manufactured in Taiwan. Increase the inlet pressure, this pump can be in front of the membrane, when there is insufficient pressure in the water system. Among the domestic reverse osmosis systems where this equipment can be installed, it is worth noting those manufactured by the following manufacturers:
- "New water".
- "Geyser".
- "Aquaphor".
- "Barrier".
What else is necessary to know about the principle of operation of a two-rotor booster pump
Gear transmission allowssynchronization of routers among themselves in booster pumps. If the gear ratio is constant, then large gas loads will cause the engine to operate in overload mode, this will sooner or later lead to its failure. The gap in this case eventually disappears, which is due to overheating of the rotors.
Rotors start to touch the stator or each other,as a consequence, jamming or bullying. Therefore, in mechanical pumps, the speed of rotation will depend on the inlet pressure. For this, a rigid mechanical connection between the motor shaft and the rotor should be eliminated. If we are talking about Japanese pumps, then this role in them performs a magnetic coupling. The rotor levitates inside the chamber, and there is no mechanical connection between the rotor and the motor.
