Cylinder piston (piston) rod with oil maintenance repair program (fāng à n): for the dump truck lift cylinder piston rod; with oil; problem (Emerson), proposed corresponding improvement measures (pointer to the solution to the problem) And has been effectively applied in the production (Produce); after investigation, it is found that there are a lot of oil rods in the piston rod of the dump truck with the dump truck, that is, when the piston rod of the cylinder is extended, sometimes it is obvious I saw a very thin layer of oil attached to the piston rod; when the piston rod retracted, it was found that oil accumulated at the cylinder head dust ring, and more oil accumulated from the cylinder head after multiple lifting Dropped down. The 45# piston rod connects the piston and the crosshead to transmit the force acting on the piston and drive the piston to move. When the hollow piston rods have the same material and the cross-sectional area is equal, the hollow piston rod has stronger torsion resistance and can withstand large external moments. The 45# piston rod supports the connecting parts of the piston work. Most of them are used in the cylinder and cylinder movement executing parts. It is a moving part with frequent movement and high technical requirements. The hydraulic piston rod cylinder, the piston rod (cylinder rod), the piston and the end cover are composed of several parts. The cylinder piston rod wear ring can improve the guiding of the cylinder, reduce the wear of the piston seal and reduce the frictional resistance. This phenomenon occurs, although it is different from the general hydraulic cylinder oil leakage; through (tōng guò) the cylinder (compressed air) piston rod for many years of overhaul data analysis (Analyse) and found (cause) The position of the piston rod seal failure generally appears on the sealing fit of the piston-piston, the top cover-hydraulic cylinder, etc., and the main fault points occur concentrated between the hydraulic cylinder and the live column, and the cylinder piston rod works. The reliability of the performance is highly dependent on the ability of the seal to work. The hydraulic cylinder is a very easily damaged component of the piston rod of the single cylinder. The cylinder cavity is mainly rusted and leaked, and the working condition and the wear during transportation (a basic type of component failure), bumping (by talking Caused by conflict) will also increase the size of the inner cavity, deform the cylinder, resulting in seal failure, so the reasonable choice of its repair method (xuanze) has special significance.
