Jordan hydraulic cylinder,unidirectional cylinder manufacturer,unidirectional cylinder

(Jordan unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in Jordan，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed unidirectional cylinder for customers from Jordan.

Introduction to unidirectional cylinder:

When the unidirectional cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the unidirectional cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

unidirectional cylinder use should try to avoid sealing belt into the unidirectional cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the unidirectional cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the unidirectional cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

The pressure of the sliding surface of the unidirectional cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the unidirectional cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

When purchasing the unidirectional cylinder, try to clarify the following parameters of the unidirectional cylinder: A. unidirectional cylinder diameter, rod diameter, stroke; B. Working pressure or unidirectional cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right unidirectional cylinder type can be found accurately and quickly.

Answers to some questions about unidirectional cylinder:

There are four cylinders in the front top of the dump truck. When the second cylinder is lifted to half the height, it suddenly falls back more than 30 cm or so, and the cylinder continues to lift.
The problem is the cylinder, the second section of the different strength of the heart. When the oil supply resistance is small, the first out, when the power is not moving, the cylinder needs to be strong, because the second section needs to pop it out after a while when the pressure is large, the oil can not keep up, so it falls back, and the oil continues to keep up.

How to deal with the surface degreasing process before spraying paint after cylinder assembly, and what degreasing agent is used?
Cylinder painting, generally using the following process (note: the cylinder is best painted, do not spray powder coating, because the powder coating curing temperature is high, will lead to sealing defects and oil leakage) : Pre-degreasing - degreasing - washing - washing - pickling - washing - washing - table adjustment - phosphating - washing - washing - drying - polishing - spray primer - spray paint degreasing agent generally use neutral or weak alkaline degreasing agent, phosphating liquid generally use zinc phosphating liquid.
