What are the common classifications and advantages of oil research vane pumps?

Page view:
The oil-grinding vane pump is a power component of the hydraulic system, which is driven by an engine or an electric motor, sucks oil from the hydraulic oil tank, forms a component that the pressure oil is discharged and sent to the actuator. The hydraulic pump is divided into a gear pump, a plunger pump, a vane pump and a screw pump according to the structure.
 
First, the type of hydraulic pump commonly used, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted as needed, called the variable pump, and the flow cannot be adjusted, called the fixed pump. According to the pump structure commonly used in hydraulic systems, it is divided into three types: gear pump, vane pump and plunger pump.
 
 
1. Gear pump: The volume is small, the structure is relatively simple, the cleanliness of the oil is not strict, and the price is relatively cheap; but the pump shaft is unbalanced, the wear is serious, and the leakage is large.
 
2. Vane pump: It is divided into double-acting vane pump and single-acting vane pump. The pump has uniform flow, stable operation, low noise, high pressure and volumetric efficiency compared to the gear pump, and the structure is more complicated than the gear pump.
 
3. Piston pump: high volumetric efficiency, small leakage, can work under high pressure, mostly used in high-power hydraulic systems; but the structure is complex, material and processing precision requirements are high, the price is expensive, and the cleanliness of oil is high.
 
Second, the advantages:
 
1. Aluminum alloy manufacturing, high strength, corrosion resistance, light weight, suitable for all kinds of environments.
 
2. The two-speed characteristic reduces the number of times of pressing, and is quickly in the low-voltage chamber in the state of load work, and immediately converts to high pressure, shortening each operation cycle.
 
3. It is equipped with a pressure regulating valve to adjust the control and set the working pressure.
