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

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

Introduction to stroke adjustable cylinder:

Protection of the stroke adjustable cylinder surface: During the dismantling process, safety protection should be carried out on the stroke adjustable cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the stroke adjustable cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the stroke adjustable cylinder should be cleaned up in time.

The piston rod of the stroke adjustable cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

If air enters the hydraulic system, the stroke adjustable cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

When the initial action of the stroke adjustable cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the stroke adjustable cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

Answers to some questions about stroke adjustable cylinder:

How to store hydraulic cylinder?
After cleaning the hydraulic cylinder with diesel or kerosene, apply lubricating oil and wrap it in oil paper, preferably in a wooden box, and store it in a dry and non-corrosive environment. The outer surface and inner surface of the hydraulic cylinder are sprayed with diesel oil, and the inner layer is covered with cloth and the outer coating of anti-rust oil is good. Put it in a dry place, clean it with diesel oil, and then apply a layer of anti-rust inside and outside the butter.

The difference between the overall cylinder and the separate cylinder of the truck?
The whole cylinder is cast in one piece, and such a cylinder generally does not leak oil. Split cylinder refers to two welded, easy to leak oil in the welding place, resulting in damage to the cylinder, or its body can not get up, many people do not use this kind of cylinder now.
