The valve core of the flow valve in the hydraulic cylinder is blocked, which is easy to cause the action failure of the hydraulic cylinder. We need to check whether there are pollutants in the oil in the hydraulic cylinder and whether the valve body is worn. It is necessary to check whether the piston rod seal is too tight, Tibet Hydraulic system Whether there are pollutants entering, whether the axis line is aligned, and whether the easily damaged components fail. If the pressure controlled by the hydraulic system is too low, the action of the hydraulic cylinder will also fail, Tibet Hydraulic system Manufacturer At this time, it is necessary to check the control pressure source to ensure that the pressure value is consistent with the specified value of the system.
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, Tibet Hydraulic system 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, Tibet Hydraulic system 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.
Because the hydraulic cylinder must bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is the most important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system. It is difficult to repair a heart problem, so the maintenance of the hydraulic cylinder should be careful. first, Tibet Hydraulic system Rust prevention is required. Because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally suffer from oxidation Tibet Hydraulic system Manufacturer The erosion of acid gas requires us to apply proper amount of grease to protect it.
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 Tibet Hydraulic system 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, Tibet Hydraulic system 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.
There are many hydraulic components on construction machinery, and sufficient hydraulic oil is required. When the hydraulic oil needs to be replaced due to its deterioration after a long time of use, some people mistakenly believe that it is only necessary to drain the oil in the hydraulic cylinder Tibet Hydraulic system Top up with new hydraulic oil. However, there are still many old hydraulic oils left in the hydraulic oil pipe and hydraulic control valve at this time. When the equipment is used, the mixing of new and old oils will speed up the deterioration of new oils. The correct oil change procedure should first drain the hydraulic oil in the hydraulic cylinder, clean the hydraulic cylinder, and then add new hydraulic oil, Tibet Hydraulic system Manufacturer Then remove the circuit header, start the engine and run at low speed to make the oil pump work and operate each mechanism separately.
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, Tibet Hydraulic system 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, Tibet Hydraulic system Manufacturer 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.
