(Costa Rica stroke adjustable cylinder,produced by Hengyu Group）

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

Introduction to stroke adjustable cylinder:

stroke adjustable cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

The difference between the integral stroke adjustable cylinder and the split stroke adjustable cylinder: The integral stroke adjustable cylinder and the split stroke adjustable cylinder in the stroke adjustable cylinder are two different stroke adjustable cylinders, and they are very different. The whole stroke adjustable cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split stroke adjustable cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and stroke adjustable cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

stroke adjustable cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

When producing oil stroke adjustable cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

Answers to some questions about stroke adjustable cylinder:

What's the use of three oil pipes on the cylinder?
The cylinder usually has an upper and lower oil chamber, one is connected to the upper oil chamber, one is connected to the lower oil chamber, sometimes a hydraulic lock will be added, that is, a hydraulic control check valve to prevent accidents when the oil pipe breaks, so the third pipe should be the control oil pipe of the hydraulic control check valve.

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.
