Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It is simple in structure and reliable in operation. When it is used to realize reciprocating movement, the reducer can be avoided, Taiyuan Oil cylinder And there is no transmission clearance, smooth movement, so it is widely used in various mechanical hydraulic systems. Output force of the hydraulic cylinder is proportional to effective area of the piston and pressure difference on both sides; The hydraulic cylinder basically consists of cylinder barrel, cylinder head Taiyuan Oil cylinder Manufacturer The piston and piston rod, sealing device, buffer device and exhaust device are composed.

Because the hydraulic cylinder must bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is the most important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system. It is difficult to repair a heart problem, so the maintenance of the hydraulic cylinder should be careful. first, Taiyuan Oil cylinder Rust prevention is required. Because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally suffer from oxidation Taiyuan Oil cylinder Manufacturer The erosion of acid gas requires us to apply proper amount of grease to protect it.

Two way hydraulic cylinder, which is one of the hydraulic cylinders, is a common and commonly used type of hydraulic cylinder. Therefore, Taiyuan Oil cylinder Manufacturer It is necessary to have a correct understanding of this kind of hydraulic cylinder and have a certain understanding, so that we can know how to use it reasonably and make full use of it. This kind of hydraulic cylinder has corresponding operation regulations and maintenance regulations, because it is in the hydraulic cylinder category. In addition, Taiyuan Oil cylinder It is necessary to have a clear and comprehensive understanding of its operation and maintenance procedures. The symptom of strain and wear is that the lifting speed of the equipment is relatively slow, accompanied by self subsidence.

1. Internal leakage of oil cylinder; 2. Internal leakage at control valve hole and valve rod; 3. Overload overflow valve is poor; 4. The valve rod is not in the middle position; 5. PPC valve is not in the middle position. Hydraulic cylinder maintenance process: 1. Whether the hydraulic lock becomes normal when it is in the determined position, if so, check the PPC valve first; 2. Conduct oil cylinder plugging oil port test, Taiyuan Oil cylinder Check whether the oil cylinder is defective, and repair the oil cylinder if it is; 3. Replace the overload overflow valve and check whether it is the fault of the overload overflow valve; 4. Whether the valve rod is jammed, Taiyuan Oil cylinder Manufacturer Check again after cleaning, otherwise the main control valve needs to be repaired.

For the same hydraulic cylinder on the Internet, some manufacturers quote more than 1200, some more than 1600, some about 1800, and even some about 3000. This situation makes the purchasing manufacturers feel puzzled and very difficult. Most manufacturers have limited procurement funds, Taiyuan Oil cylinder Therefore, if you want to achieve the predetermined purchase goal, you need to choose the hydraulic cylinder with high cost performance ratio, good quality and low price. However, the price gap of hydraulic cylinders in the market is staggering, Taiyuan Oil cylinder Manufacturer If you choose cheap oil cylinder rashly, the quality cannot be guaranteed, which will lead to endless troubles.
