Exploring the principle of hydraulic system of crusher

1. The working principle of the crusher
A crusher is a kind of machinery and equipment that crushes large pieces of material into small pieces. It is usually used in mines, construction sites and other fields.The working principle of the crusher is mainly to drive the pulley through the motor, so that the upper and lower jaw plates move relatively, and the large pieces of material can be crushed into the required small pieces of material through the extrusion, friction and shear in the crushing chamber.The hydraulic system plays a vital role in the work of the crusher.
2. The composition of the hydraulic system
The hydraulic system consists of a high-pressure oil pipe, a pressure valve, a direction control valve, a working cylinder, a fuel tank and other parts.Among them, the high-pressure oil pipe is connected to the fuel tank, and the high-pressure oil pump sends the hydraulic oil to the pressure valve through the high-pressure oil pipe. The setting of the pressure valve presets the maximum working pressure of the system. When the system pressure reaches this value, the pressure valve will act, so that the differential pressure is reduced, thereby protecting the normal operation of the hydraulic system.The direction control valve determines the direction of hydraulic flow in the hydraulic system and is also an important part in the work of the crusher.
Three, the working principle of the hydraulic system
In the work of the crusher, the hydraulic system provides sufficient hydraulic energy through the high-pressure oil pipe and the high-pressure oil pump to enable the crusher to operate.The working principle of the hydraulic system is to use liquid to transfer pressure in a closed pipeline. Under the action of a high-pressure oil pump, the hydraulic oil continues to flow in the high-pressure oil pipeline, providing sufficient hydraulic energy to the working cylinder, direction control valve, pressure valve and other components to promote the rise and fall of the upper and lower jaw plates, thereby completing the crushing of materials.
4. Maintenance and maintenance of hydraulic system
In order to ensure the normal operation of the hydraulic system of the crusher, the system should be maintained and maintained regularly.First of all, check whether the oil quality is clean. If the oil quality is abnormally turbid or there are impurities, a new hydraulic oil should be replaced; secondly, check whether there is oil leakage in the hydraulic pipeline. If so, the seals should be replaced immediately and repaired; At the same time, pay attention to the pressure setting of the hydraulic system to ensure that the working pressure of the system is within a safe range.
