Two way hydraulic cylinder, which is one of the hydraulic cylinders, is a common and commonly used type of hydraulic cylinder. Therefore, Guizhou Hydraulic equipment manufactor 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 equipment 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 Guizhou Hydraulic equipment 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, Guizhou Hydraulic equipment manufactor Then remove the circuit header, start the engine and run at low speed to make the oil pump work and operate each mechanism separately.

The connection between the oil cylinder and the actuator and the connection between the oil cylinder and the oil pipe cannot be the same, because there must be some differences between the connection between the oil cylinder and different products. In addition, during the use of the oil cylinder, it is necessary to avoid scratches, Guizhou Hydraulic equipment Because if this problem occurs, it will affect the normal use of the oil cylinder. At present, there is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders, and it is necessary to design hydraulic cylinders according to these standards. So far, Guizhou Hydraulic equipment manufactor There is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders.

The hydraulic system is composed of various hydraulic components. All hydraulic components are organically connected into a complete hydraulic system by pipes, joints, integrated valve blocks and other parts. Therefore, whether the hydraulic pipeline is installed correctly Guizhou Hydraulic equipment Firm, reliable and neat will have an important impact on the working performance of the hydraulic system. Check the quality of pipes. Find out the pipe material Guizhou Hydraulic equipment manufactor Whether the size and quality meet the design requirements; Check whether there is serious flattening or bending on the appearance of the pipe, whether there is corrosion on the surface of the inner and outer walls of the pipe, whether there is crack on the outer wall and other defects.

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 equipment It permeates all fields of the national economy, including agricultural machinery, automobiles, light textile, shipbuilding, petroleum, aviation and machine tool industries, Guizhou Hydraulic equipment manufactor Hydraulic technology lists some application examples of hydraulic and pneumatic transmission.

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 equipment 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 equipment manufactor Check again after cleaning, otherwise the main control valve needs to be repaired.
