Hydraulic oil cylinder is used in many industries. Once it fails, it will have a far-reaching impact and hinder the progress of all work. In fact, many customers said that the hydraulic cylinder could not operate, Handan Hydraulic machinery In order to solve this problem in time, we should first find out what causes the problem. Generally speaking, the problem that the hydraulic cylinder cannot act often occurs on the newly installed hydraulic cylinder, Handan Hydraulic machinery Price Generally, it is necessary to start from external reasons, such as whether the mechanism pulled by the hydraulic cylinder has excessive resistance, whether it is stuck, and whether it is against other parts; Whether the pressure at the oil inlet of the hydraulic cylinder is within the specified range.

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, Handan Hydraulic machinery 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, Handan Hydraulic machinery Price If you choose cheap oil cylinder rashly, the quality cannot be guaranteed, which will lead to endless troubles.

1. There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system in the pressure holding state is consistent with the initial setting. Check the hydraulic oil and suction oil filter before measuring the pressure, Handan Hydraulic machinery Replace or clean it. Secondly, check the main overflow valve of the reversing control multi way valve to see if it is damaged or blocked by foreign matters, Handan Hydraulic machinery Price Clean it. If your pump is a gear pump, the problem should be minor in general. 2. Next, let's look at the traffic problem.

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, Handan Hydraulic machinery 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, Handan Hydraulic machinery 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.

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