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, Dongguan Hydraulic press cylinder 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 Dongguan Hydraulic press cylinder manufactor The piston and piston rod, sealing device, buffer device and exhaust device are composed.

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, Dongguan Hydraulic press cylinder 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, Dongguan Hydraulic press cylinder manufactor 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.

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, Dongguan Hydraulic press cylinder 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, Dongguan Hydraulic press cylinder manufactor 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.

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, Dongguan Hydraulic press 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, Dongguan Hydraulic press 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.

Two way hydraulic cylinder, which is one of the hydraulic cylinders, is a common and commonly used type of hydraulic cylinder. Therefore, Dongguan Hydraulic press cylinder 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, Dongguan Hydraulic press cylinder 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.

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, Dongguan Hydraulic press cylinder 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, Dongguan Hydraulic press cylinder manufactor If you choose cheap oil cylinder rashly, the quality cannot be guaranteed, which will lead to endless troubles.
