How is the hydraulic system of the fully automatic hydraulic block machine better than the pneumatic system:
The hydraulic system of the fully automatic hydraulic block machine is better than the pneumatic system. Whether it is pneumatic or hydraulic transmission, the working principles and basic circuits of the two are the same, but their media are different, and there are certain differences in nature.
1. The medium used in pneumatic transmission is air, the medium used in hydraulic transmission of automatic hydraulic block machine is hydraulic oil, and hydraulic control oil is used as the working medium, so the heat generated due to power loss can be transferred from the place where it occurs Take it elsewhere, so that under a certain power condition, the size of the fully automatic hydraulic block machine components can be greatly reduced;
2. The hydraulic pressure is higher than the pneumatic pressure, the power is large, and the hydraulic pressure must be used for heavy loads.
3. The hydraulic system of the automatic hydraulic block machine has higher precision than the pneumatic transmission. The cylinder generally has two actions: extending and retracting. The actions of the hydraulic system can be varied. After adding a proportional valve or a servo valve, the acceleration and speed of the action can be realized. deceleration action.
4. There is a pause during the action. If the oil cylinder is required to have a pause in the middle position, the oil cylinder must be used. The cylinder can also stop, but the position deviation is too large.
5. The volume change rate is too large when the gas is compressed, and the volume change rate is very small when the hydraulic system of the automatic hydraulic block machine is compressed.
