Hydraulic pump is a kind of hydraulic component which provides pressurized liquid for hydraulic transmission, and it is also a kind of pump. Its function is to convert the mechanical energy of power engines (such as motors and internal combustion engines) into the pressure energy of liquids. The working principle of the single plunger pump is that the cam is driven by the motor to rotate. When the cam pushes the plunger upward, the sealing volume formed by the plunger and the cylinder block decreases, and the oil is extruded from the sealing volume and is discharged through the one-way valve to the desired place. When the cam rotates to the downward part of the curve, the spring forces the plunger downward to form a certain degree of vacuum, and the oil in the tank enters the sealing volume under the action of atmospheric pressure. The cam makes the plunger rise and fall continuously, the sealing volume decreases and increases periodically, and the pump sucks and discharges oil continuously.
Hydraulic system consists of the following five main parts:
1. Energy device is a device that supplies pressure oil of hydraulic system and converts mechanical energy into hydraulic energy. The most common form is hydraulic pumps.
2. The actuator is a device that converts hydraulic energy into mechanical energy. Its forms are hydraulic cylinders with linear motion and hydraulic motors with rotary motion. They are also called actuators of hydraulic systems.
3. The control and regulation device is a device that controls or regulates the pressure, flow rate or flow direction in the system. Such as relief valve, throttle valve, reversing valve, open-stop valve, etc.
4. Auxiliary devices other than the above three parts, such as fuel tank, oil filter, tubing, etc. They are essential to ensure the normal operation of the system.
5. Hydraulic oils, which transmit energy in working media.
