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, Tibet Hydraulic equipment 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, Tibet Hydraulic equipment 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.
The failure of the hydraulic cylinder due to improper design and manufacture is because the oil pressure cannot act on the effective working area of the piston when the piston travels to the end point and returns, or the effective working area is too small when starting, which causes problems. When the transverse load of the hydraulic cylinder is too large, the force is not strong or the cylinder is bitten, the same consequences will occur. Tibet Hydraulic equipment Therefore, when installing the hydraulic cylinder, the axis position of the cylinder must be consistent with the movement direction; Tibet Hydraulic equipment Manufacturer And ensure that the load borne by the hydraulic cylinder passes through the cylinder axis as far as possible without eccentricity, so that the problem can be solved.
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 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, Tibet Hydraulic equipment 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.
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 equipment 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 equipment 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.
The oil cylinder shall be assembled in a special workshop or assembly area, and the temperature shall be kept at 20~250C, Tibet Hydraulic equipment Manufacturer It shall be far away from the tuyere, dust and cutting area, with fresh air, no dust and no noise; Avoid direct glare. The assembly room shall be equipped with installation platform, sufficient working position apparatus, assembly turnover vehicle Tibet Hydraulic equipment Lifting and hoisting equipment and the following special basic equipment. a: Cylinder loader; b: Another cylinder cleaning machine is used to heat and clean another part; c: Pressure test equipment, used for pressure test of oil cylinder; d: The air duct is used to clean and dry the other parts after cleaning.
Because the hydraulic cylinder has to bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is an important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system, Tibet Hydraulic equipment It is difficult to repair the heart problem, so the maintenance of the hydraulic cylinder should be careful. First, rust prevention. Because the piston part of the hydraulic cylinder will extend the cylinder in the working state, Tibet Hydraulic equipment Manufacturer Naturally, it will be corroded by oxide and acid gas, which requires us to coat it with proper grease for protection.
