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, Guizhou Hydraulic 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, Guizhou Hydraulic cylinder Manufacturer Check again after cleaning, otherwise the main control valve needs to be repaired.
Two way hydraulic cylinder, which is one of the hydraulic cylinders, is a common and commonly used type of hydraulic cylinder. Therefore, Guizhou Hydraulic 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, Guizhou Hydraulic 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 only drain the oil in the hydraulic cylinder and fill it with new hydraulic oil. However, there are still many old hydraulic oils left in the hydraulic oil pipe and hydraulic control valve, Guizhou Hydraulic cylinder When the equipment is used, the mixing of new and old oil will speed up the deterioration of new oil. The correct oil change procedure should first drain the hydraulic oil in the hydraulic cylinder, Guizhou Hydraulic cylinder Manufacturer After cleaning the hydraulic cylinder, add new hydraulic oil, remove the circuit header, start the engine and run at low speed to make the oil pump work.
Compared with mechanical transmission, hydraulic cylinder transmission is a new transmission form. Hydraulic transmission has a history of more than 200 years since the birth of hydraulic press, but hydraulic transmission has been going on for many years. Especially after the 1960s, with the development of atomic energy science, space and hydraulic technology, Guizhou Hydraulic cylinder It permeates all fields of the national economy, including agricultural machinery, automobiles, light textile, shipbuilding, petroleum, aviation and machine tool industries, Guizhou Hydraulic cylinder Manufacturer Hydraulic technology lists some application examples of hydraulic and pneumatic transmission.
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, Guizhou Hydraulic 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 Guizhou Hydraulic cylinder Manufacturer The piston and piston rod, sealing device, buffer device and exhaust device are composed.
