The difference between hydraulic cylinders and pneumatic cylinders
A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). According to the structural form of commonly used hydraulic cylinders, they can be divided into four types: piston type, plunger type, telescopic type, and swing type. Cylinder is the air pressure that converts air pressure energy into mechanical energy System components. The difference between hydraulic cylinder and cylinder is mainly reflected in the following four aspects:
1. The first difference between a hydraulic cylinder and a pneumatic cylinder is that their respective working principles are different. This is the essential difference: the air pressure of the pneumatic cylinderThe operating pressure of the system is generally in the range of 0.2-1.0Mpa, so the pneumatic cylinder cannot be used as a high-power power component. Hydraulic cylinders are different. Hydraulic cylinders can be used as relatively high-power components using a hydraulic system.
2. In terms of scarcity of resources, there is a second difference between hydraulic cylinders and pneumatic cylinders: the normal operation of hydraulic cylinders depends on hydraulic pressureOil, oil is a non-renewable resource and cannot be recycled, and the used hydraulic oil will have an impact on the environment;The pneumatic cylinder is different. It uses air to complete its operation. The air is inexhaustible and there is no cost or supply.The used gas is discharged directly into the atmosphere. It is easy to handle, reusable and does not produce any pollution!
3. From the hydraulic cylinder and In terms of the working resistance of the cylinder, the third difference between the hydraulic cylinder and the pneumatic cylinder: the air viscosity is small, the resistance is small span>In hydraulic oil.
4. In terms of resource usage efficiency, the fourth difference between hydraulic cylinders and pneumatic cylinders: the compression rate of air is much greater than that of hydraulic oil, soIts work stability and response are much worse.
What is the reason for hydraulic cylinder rebound
1. Hydraulic cylinder leakage;
2. The reason is the control valve. Check whether there are two directional valves in series in the circuit. One of the two valves is fast and the other is slow;
3. The reason for the external load is that the external load is too large when it is in the middle position.
