How does a hydraulic pump work?
1. The function of engine hydraulic pump
The main function of the engine hydraulic pump is to convert the mechanical energy of the engine into hydraulic energy to provide power to the entire hydraulic system. The hydraulic system can provide more reliable and effective power output for the engine, and can also provide power support for other hydraulic equipment in the vehicle.
2. Principle of engine hydraulic pump
The working principle of the engine hydraulic pump is to rely on the power generated by the rotation of the engine to drive the rotor of the hydraulic pump, causing the rotor to rotate along the pump chamber. The hydraulic pump converts mechanical energy into hydraulic energy, draws liquid in from the low-pressure area (suction end), and uses the high-pressure area (discharge end) to discharge the liquid out of the pump chamber to provide power to other equipment in the hydraulic system.
3. Types of engine hydraulic pumps
Engine hydraulic pumps can be divided into many types according to their structures and types. Common hydraulic pump types include:
1. Gear pump: The rotation of the gear enables the pump to draw liquid in, compress and discharge it.
2. Piston pump: It consists of a device with a piston and a cam or plunger that drives the device. It is widely used in ball bearings, lubricating oil systems, etc.
3. Screw pump: Through the rotation of two or more screws, liquid is extracted from a lower pressure area, and the liquid is compressed into high-pressure hydraulic pressure in the pump chamber and discharged.
4. Maintenance of engine hydraulic pump
The engine hydraulic pump is the core component of the automobile engine hydraulic system, and routine maintenance is particularly important. mainly include:
1. Regularly check the working status of the hydraulic pump and hydraulic system to ensure that the hydraulic system is working properly.
2. Regularly replace the oil seals, sealing rings and other wearing parts of the hydraulic pump to ensure the sealing performance of the hydraulic pump.
3. Clean the filter in the hydraulic pump and hydraulic system regularly to avoid filter clogging and affecting the working efficiency of the hydraulic pump.
In short, the engine hydraulic pump is an indispensable component of the car engine, and its normal operation is crucial to ensuring the normal operation of various car functions.
