What is the problem so that operational errors caused by hydraulic cylinders 2013-5-25

Hydraulic cylinder wants to play everyone is familiar with many of my friends in the use of hydraulic cylinders, it tends to encounter such problems, Xiao Bian special trip to visit a few friends about the problems they are summarized below specific problems and solutions method is still to let our old friend Jiang Yi hydraulic machinery to give you described.

1 hydraulic oil does not reach the hydraulic cylinder
For this problem we can look at pipes and oil in particular, joint positions have not been blocked. Look at how the situation like relief valve seal. Need to look at the solenoid valve has not burned his spring.
(2) the oil pressure is too low, less than the requirements
We can carry out checks on the oil system to see if there is a leak to put this issue is resolved. Then check the piston rod seal damage and see if there are old loose. Hydraulic pump and the pressure in the valve view.
3 too much pressure on the piston rod
To ensure that the axis of the cylinder and the cylinder position is the same. Jiang Yi hydraulic machinery hydraulic cylinder to withstand the load to go through the cylinder axis, so you can prevent eccentric problems.
4 parts too close to the hydraulic cylinder, resulting in excessive friction
Between the piston rod and the guide sleeve for use H8/f8 used interchangeably. To seal the size and tightness control. Should seal friction lining to a suitable size.

Of course, the fact that we use in the process of hydraulic cylinders, the question always in the generation and change, we can only say a few common questions to help you to solve, if not solve the problem we have to welcome everyone to Jiang Yi hydraulic machinery for consultation
