Hydraulic machine manufacturers to analyze the depth of the secret cylinder

In order to prevent the piston rod and other elongated pieces of bending or deformation, the application of iron trapped suspended placement, the use of cushioning cylinder block balanced. Hydraulic machine manufacturers and technical personnel should be in accordance with the requirements and order to dismantle the cylinder, can not be arbitrarily changed. When disassembling, should prevent the damage piston rod top thread, the oil mouth thread and the piston rod surface, the cylinder liner inner wall and so on. In order to prevent the piston rod and other elongated pieces of bending or deformation, the application of iron trapped suspended placement, the use of cushioning cylinder block balanced. If any obstacles are encountered during the disassembly, it shall not be forcibly carried out. The cause shall be ascertained and the problems shall be solved before dismantling.

Before and after disassembly, the components in the cylinder should be avoided by the environment or man-made pollution, the demolition environment should be clean. Before and after unloading, try to create conditions to prevent parts of the cylinder from being contaminated by dirt and contaminants. For example, the disassembly should be carried out in a clean environment; after disassembly all parts covered with plastic sheeting, do not use cotton cloth or other work with the cloth cover. After the cylinder is disassembled, the parts are carefully inspected to determine what needs to be repaired or replaced. After assembly of the cylinder, the piston assembly should be moved to check for jamming. But also a number of reciprocating motion, in the case of low pressure in order to discharge the gas cylinder. Seal to be properly installed, the connection must use a wrench to tighten.

The use of hydraulic cylinders in the process of its malfunction or action failure, the reason for that? How to solve? For this problem, the following Xiaobian to give its specific answers.

1. Spool or valve hole is stuck or blocked, may be its internal dirt, colloidal sediment, etc., resulting. At this time, we should check the oil contamination, as well as the degree of wear of the valve body, the need to replace the oil or body, whether the fuel tank cleaning.

2. Piston rod and cylinder stuck, the reason may be too tight on the piston and piston rod seal, parts failure, the load is too large, there is a debris, these are possible, to one by one Investigation and resolution.
