Hydraulic oil cylinder is used in many industries. Once it fails, it will have a far-reaching impact and hinder the progress of all work. In fact, many customers said that the hydraulic cylinder could not operate, Zhanjiang Cylinder In order to solve this problem in time, we should first find out what causes the problem. Generally speaking, the problem that the hydraulic cylinder cannot act often occurs on the newly installed hydraulic cylinder, Zhanjiang Cylinder Price Generally, it is necessary to start from external reasons, such as whether the mechanism pulled by the hydraulic cylinder has excessive resistance, whether it is stuck, and whether it is against other parts; Whether the pressure at the oil inlet of the hydraulic cylinder is within the specified range.

Two way hydraulic cylinder, which is one of the hydraulic cylinders, is a common and commonly used type of hydraulic cylinder. Therefore, Zhanjiang Cylinder Price 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, Zhanjiang 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.

There are many hydraulic components on construction machinery, and sufficient hydraulic oil is required. When the hydraulic oil needs to be replaced due to its deterioration after a long time of use, some people mistakenly believe that it is only necessary to drain the oil in the hydraulic cylinder Zhanjiang Cylinder Top up with new hydraulic oil. However, there are still many old hydraulic oils left in the hydraulic oil pipe and hydraulic control valve at this time. When the equipment is used, the mixing of new and old oils will speed up the deterioration of new oils. The correct oil change procedure should first drain the hydraulic oil in the hydraulic cylinder, clean the hydraulic cylinder, and then add new hydraulic oil, Zhanjiang Cylinder Price Then remove the circuit header, start the engine and run at low speed to make the oil pump work and operate each mechanism separately.

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, Zhanjiang 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, Zhanjiang Cylinder Price Check again after cleaning, otherwise the main control valve needs to be repaired.
