If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. Jinhua Hydraulic cylinder Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Jinhua Hydraulic cylinder manufactor The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.
Fluid cleanliness. The cleanliness of the system oil will have a very important impact on the hydraulic cylinder. Hydraulic shock and vibration hydraulic cylinders will be affected by the performance of components, pipeline and medium characteristics, etc., which will be accompanied by hydraulic shock and vibration. Generally speaking, if the oil temperature is too high or too low, Jinhua Hydraulic cylinder manufactor Will have a great impact on the working efficiency of the hydraulic cylinder. If the oil temperature of the hydraulic cylinder is too high or too low, the physical and chemical properties of the medium will change, Jinhua Hydraulic cylinder As a result, the viscosity of the working medium decreases or the possibility of leakage increases.
Items to be checked when the speed of hydraulic cylinder slows down. 1. Where and what type of oil cylinder has been used for several years, Jinhua Hydraulic cylinder What is the working pressure. You don't have any of these. How can I troubleshoot them for you. Check the lower seal if there is internal leakage. 2. It is likely that the internal working pressure of the oil cylinder has decreased. 3. Check whether the system is blocked, Jinhua Hydraulic cylinder manufactor In addition, check whether the oil cylinder seal ring is damaged, and then check whether the piston rod is damaged. Basically, these aspects can identify the problem.
The failure of the hydraulic cylinder due to improper design and manufacture is because the oil pressure cannot act on the effective working area of the piston when the piston travels to the end point and returns, or the effective working area is too small when starting, which causes problems. When the transverse load of the hydraulic cylinder is too large, the force is not strong or the cylinder is bitten, the same consequences will occur. Jinhua Hydraulic cylinder Therefore, when installing the hydraulic cylinder, the axis position of the cylinder must be consistent with the movement direction; Jinhua Hydraulic cylinder manufactor And ensure that the load borne by the hydraulic cylinder passes through the cylinder axis as far as possible without eccentricity, so that the problem can be solved.
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, Jinhua Hydraulic cylinder It permeates all fields of the national economy, including agricultural machinery, automobiles, light textile, shipbuilding, petroleum, aviation and machine tool industries, Jinhua Hydraulic cylinder manufactor Hydraulic technology lists some application examples of hydraulic and pneumatic transmission.
