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, Changsha 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, Changsha Hydraulic press cylinder 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.

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. Changsha Hydraulic press cylinder Therefore, when installing the hydraulic cylinder, the axis position of the cylinder must be consistent with the movement direction; Changsha Hydraulic press cylinder Price 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.

As the structure and size of various hydraulic cylinders are different, the disassembly sequence is slightly different. Generally, drain the oil in the two chambers of the oil cylinder, remove the cylinder head, and finally remove the piston and piston rod. Changsha Hydraulic press cylinder When disassembling the cylinder head of the hydraulic cylinder, special tools shall be used for the key or snap ring of the internal key type connection, and flat shovel is prohibited; Flange end caps must be pushed out with screws, and hammering or hard prying is not allowed. When it is difficult to draw out the piston and piston rod, do not force them out, Changsha Hydraulic press cylinder Price The reason shall be found out before disassembly. Before and after unloading, try to create conditions to prevent the parts of the hydraulic cylinder from being polluted by the surrounding dust and impurities.

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, Changsha 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, Changsha Hydraulic press cylinder Price 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.
