Where Is The Application Of The Hydraulic Pump?

Common categories of hydraulic pump:

1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump.

Output flow can be adjusted according to the need to be called variable pump, flow can not be regulated by a quantitative pump.

2, according to the hydraulic system commonly used in the pump structure is divided into: gear pump, vane pump and piston pump 3 kinds.

Gear Pump: Small size, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper, but the pump shaft is unbalanced, serious wear, leakage.

Vane pump: It is divided into double action vane pump and single acting vane pump. This pump flow uniformity, smooth operation, low noise, pressure and volumetric efficiency than gear pump high, the structure of the gear pump complex.

Plunger pump: High volumetric efficiency, small leakage, can work under high pressure, mostly used in high-power hydraulic system, but the structure of complex, material and processing precision requirements, high price, high oil cleanliness requirements.


The hydraulic pump is usually made of aluminum alloy, high strength, corrosion resistance, light weight, suitable for various environments.

Two-speed characteristics reduce the number of times, in the low-pressure chamber quickly in a load-hard state, immediately converted to high pressure, shorten each operating cycle.

Equipped with pressure regulating valve, adjustable control and set working pressure.

Where is the application of the hydraulic pump, the flash steamer, condenser, turbine, and other parts of the air pump first pumped into a certain vacuum system, then start the warm water pump to the surface of the flash device, because the system has maintained a certain degree of vacuum, so zoned in the air vapor spraying ice, Jiang ice warm water in the flash steamer evaporation into steam. Steam flow through the pipeline, driving power generation open cycle power system from the nozzle to promote turbine power generation. From the turbine discharged from the low steam cooling water cooled, fresh seawater, from the pump inhalation evaporation to promote the turbine is called the operating mode of the open system.
