Electric hydraulic pump classification composition

The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. Hydraulic system commonly used in the pump gear pump, vane pump and plunger pump 3.
Gear pump: small size, simple structure, lax requirements for oil cleanliness, and cheaper price; but the pump shaft is subject to unbalanced force, serious wear and large leakage.
Vane pump: divided into double acting vane pump and single acting vane pump. This kind of pump has uniform flow, stable operation, low noise, higher working pressure and volumetric efficiency than gear pumps, and more complicated structure than gear pumps. Plunger pump: high volumetric efficiency, small leakage, can work under high pressure, mostly used in high-power hydraulic systems; but the structure is complex, the material and processing accuracy requirements are high, the price is expensive, and the oil cleanliness requirements are high. Generally, the piston pump is used when the gear pump and the vane pump cannot meet the requirements. There are some other forms of hydraulic pumps, such as screw pumps, but the application is not as common as the above three.
Plunger pump: Domestic plunger pump can also meet the needs of domestic customers. The pressure can reach 80MPA, but the price is cheaper than imported ones, and there is no problem with quality and performance.
Hydraulic pump composition:
The components of the hydraulic system should be composed of the following five main parts:
1. Energy device It is a device that supplies pressure oil to the hydraulic system and converts mechanical energy into hydraulic energy. **The common form is a hydraulic pump.
2. Actuator It is a device that converts hydraulic energy into mechanical energy. Its form has a linear motion of the hydraulic cylinder, a rotary motion of the hydraulic motor, they are also known as the implementation of the hydraulic system components.
3. Control and adjustment device It is a device that controls or adjusts the pressure, flow or flow direction in the system. Such as overflow valve, throttle valve, reversing valve, open-stop valve, etc.
4. Auxiliary device Other devices other than the above three parts, such as fuel tank, oil filter, oil pipe, etc. They are essential to ensure that the system works properly.
5. The working medium is a fluid that transfers energy, namely hydraulic oil, etc.
