What are the faults of hydraulic cylinder of portable self-loading forklift?
As the name implies, the hydraulic system is very important for the portable self-loading forklift, and the failure of the hydraulic system will result in the failure of the whole forklift to complete normal operation. The hydraulic cylinder is an important part of the hydraulic system, no matter what the forklift price is. It can convert hydraulic energy into mechanical energy and perform rectilinear reciprocating motion, with simple structure and more stable motion. Although it has many advantages, some minor failures are unavoidable. Today, the forklift manufacturer will tell you what are the common faults of the portable self-loading forklift and how to deal with them.
What if the thrust of the portable self-loading forklift hydraulic cylinder is insufficient and the speed is slow? It may be caused by the following reasons: First, the clearance between the piston and the inner diameter of the cylinder block is too large, causing serious internal leakage; Second, the piston rod bends and the resistance increases; Third, the piston seal ring is damaged, the leakage increases or the friction increases; Fourth, the inner surface of the oil cylinder is deformed, causing oil to pass through both ends. No matter what the forklift price is, in this case, first check whether the seal ring is damaged, and if it is damaged, replace it in time. Then check whether the piston rod is bent, and rectify it if bent. Next, check the clearance between the piston and the inner diameter of the cylinder block. If it is too large, replace the piston.
What if the hydraulic cylinder of the portable self-loading forklift leaks hydraulic oil? There may be several reasons as follows: First, the piston rod seal ring is damaged; Second, the pipe joint is poorly sealed; Third, the cylinder head is poorly sealed. In this case, first check whether there is leakage at the pipe joint. If there is, check whether it is caused by the damage of the seal ring or the scar on the contact surface. Find out the cause and then repair or replace it. If there is no problem with the pipe joint, check whether the piston rod is strained. If this problem exists, repair the piston rod. If it does not exist, replace the seal ring. Finally, no matter what the forklift price is, check the sealing condition of the cylinder head, and repair or replace the cylinder head as appropriate.
Don't worry if the hydraulic cylinder of the portable self-loading forklift has problems. There are only a few common faults. No matter what the forklift price is, check according to the forklift manufacturer's instructions, and then repair or replace the parts to quickly solve the problem.
