(Vietnam stroke adjustable cylinder,produced by Hebei Hengyu company)

stroke adjustable cylinder are widely used in Vietnam,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed stroke adjustable cylinder for customers from Vietnam.

Introduction to stroke adjustable cylinder:

When the stroke adjustable cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the stroke adjustable cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the stroke adjustable cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

The material of the sliding part of the stroke adjustable cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

When the stroke adjustable cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the stroke adjustable 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.

When installing the stroke adjustable cylinder pipe, the pipe should be cleaned after installation, and should not pass through the stroke adjustable cylinder block, and the by-pass pipe must be installed in front of the oil port of the stroke adjustable cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the stroke adjustable cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the stroke adjustable cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

Answers to some questions about stroke adjustable cylinder:

By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.

How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.
