Double Acting Hydraulic Press Cylinder

The effective area of its two chambers is different, because it only has a piston rod on one side of the piston. When supplying oil to different chambers, the piston moves at different speeds with the same amount of oil. If the load force to be overcome is the same, the oil supply pressure required by different cavities of the hydraulic cylinder is different, or after setting the system pressure, the load pressure that the two directions of the hydraulic cylinder can overcome is different, which is the structure and working principle of the hydraulic cylinder.

Compared with mechanical and power transmission methods, the hydraulic system is not only small and light in size, light weight, but also the same power as large -scale mechanical transmission output, which means that the weight of its unit power is light, which makes the system layout and connection of connection and connection The installation flexibility is very large, so it can constitute a complex system that is difficult to form in other methods. The hydraulic system drives the pressure of mechanical energy into hydraulic oil by the engine to drive the hydraulic oil cylinder and motor.

 

All parameters can be customized

Parameters of the sample

1.Do not drive the load while working

The main performance is inaccurate stop of piston rod, insufficient thrust, speed drop, unstable work, etc. The reasons are as follows:

(1) Internal leakage of hydraulic cylinder. Internal leakage of hydraulic cylinder includes leakage caused by excessive wear of hydraulic cylinder seal, piston rod and seal cap seal and piston seal.

The reason for the seal leakage between the piston rod and the seal cap is that the seal is wrinkled, squeezed, torn, worn, aging, deteriorated, deformed, etc. At this time, the new seal should be replaced.

2.There are many cases of foreign bodies entering from pipelines.
a. Do not pay attention to cleaning. Pipeline installation after cleaning, should not be through the cylinder, must be installed in the cylinder in front of the oil port of the by-pass line. This is important. Otherwise, the foreign body in the pipeline will enter the cylinder, once entered, that is, it is difficult to exclude, but into the cylinder body to transport foreign bodies. Moreover, when cleaning, we should consider the removal method of foreign bodies in the installation pipeline operation. In addition, the corrosion in the pipe should be cleaned before the installation of the pipe, and the rust must be completely removed.
b. Chips formed during pipe processing. The pipe should not be left behind when it is deburring at both ends after the fixed size processing. Moreover, placing steel pipes near the site where welding pipes are performed is the cause of mixing welding foreign bodies. The pipes placed near the welding operation should be sealed. It is also important to note that pipe fitting materials should be prepared on a dust-free workbench.
c. Sealing belt into the cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing belt is often used in installation and inspection. If the winding method of linear and ribbon-shaped sealing materials is wrong, the sealing belt will be cut off and enter the cylinder. The wire belt seal on the sliding part of the winding will not cause what effect, but will cause the cylinder check valve action is not good or cause the buffer valve can not be adjusted to the end; For the circuit, may cause the reversing valve, relief valve and reducing valve action failure.
