1、 If the groove is too deep, two situations will occur: A. If the gap between the seal root and the groove becomes larger, the seal root will become unstable. B. The interference between the sealing lip and the sealing surface becomes smaller, Guangzhou Hydraulic equipment The rebound force of the seal becomes smaller, and the failure rate of low-pressure oil leakage will increase when the piston rod jumps. 2、 If the groove is too shallow, two situations will also occur: A. The interference between the sealing lip and the sealing surface will increase, and the contact area will increase, which will lead to greater friction, Guangzhou Hydraulic equipment Price The increased heat accelerates the damage of the seal lip. B. As a result, the clearance at the seal root becomes smaller, and the probability of the seal root being squeezed out when the oil cylinder is under high pressure increases.

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. Guangzhou Hydraulic equipment Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Guangzhou Hydraulic equipment Price 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.

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, Guangzhou Hydraulic equipment 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 Guangzhou Hydraulic equipment Price The piston and piston rod, sealing device, buffer device and exhaust device are composed.

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, Guangzhou Hydraulic equipment 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, Guangzhou Hydraulic equipment Price 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.

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

For the same hydraulic cylinder on the Internet, some manufacturers quote more than 1200, some more than 1600, some about 1800, and even some about 3000. This situation makes the purchasing manufacturers feel puzzled and very difficult. Most manufacturers have limited procurement funds, Guangzhou Hydraulic equipment Therefore, if you want to achieve the predetermined purchase goal, you need to choose the hydraulic cylinder with high cost performance ratio, good quality and low price. However, the price gap of hydraulic cylinders in the market is staggering, Guangzhou Hydraulic equipment Price If you choose cheap oil cylinder rashly, the quality cannot be guaranteed, which will lead to endless troubles.
