Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, ynz Hydraulic press cylinder The high-pressure oil in the circuit will be ejected rapidly. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, and then cut off the power supply or power source to stop the hydraulic device. During unloading, prevent damage to the thread at the top of the piston rod, the thread at the oil port, the surface of the piston rod, the inner wall of the cylinder liner, etc. ynz Hydraulic press cylinder Manufacturer In order to prevent the piston rod and other slender parts from bending or deformation, the skid shall be used to support and balance during placement.
The hydraulic cylinder is the actuating element that converts hydraulic energy into mechanical energy in the hydraulic system. The faults can be basically summarized as hydraulic cylinder misoperation ynz Hydraulic press cylinder Manufacturer It is unable to push the load and the piston slips or crawls. It is not uncommon for hydraulic cylinder failure to cause equipment shutdown. Therefore, ynz Hydraulic press cylinder Attention should be paid to the fault diagnosis, use and maintenance of hydraulic cylinder. The main reason for excessive wear of piston seals is that the speed control valve is improperly adjusted, resulting in excessive back pressure, improper installation of seals or contamination of hydraulic oil. Secondly, foreign matters enter during assembly and the quality of sealing materials is poor.
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, ynz 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, ynz Hydraulic press cylinder Manufacturer 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.
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, ynz 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 ynz Hydraulic press cylinder Manufacturer The piston and piston rod, sealing device, buffer device and exhaust device are composed.
The connection between the oil cylinder and the actuator and the connection between the oil cylinder and the oil pipe cannot be the same, because there must be some differences between the connection between the oil cylinder and different products. In addition, during the use of the oil cylinder, it is necessary to avoid scratches, ynz Hydraulic press cylinder Because if this problem occurs, it will affect the normal use of the oil cylinder. At present, there is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders, and it is necessary to design hydraulic cylinders according to these standards. So far, ynz Hydraulic press cylinder Manufacturer There is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders.
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, ynz Hydraulic press cylinder 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, ynz Hydraulic press cylinder Manufacturer 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.
