(Spain stroke adjustable cylinder,produced by Hengyu Hydraulic Co., Ltd）

stroke adjustable cylinder are widely used in Spain，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed stroke adjustable cylinder for customers from Spain.

Introduction to stroke adjustable cylinder:

When the stroke adjustable cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the stroke adjustable cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil stroke adjustable cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical stroke adjustable cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the stroke adjustable cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

The internal leakage of the stroke adjustable cylinder is an important indicator to measure the quality of the stroke adjustable cylinder: the internal leakage of the stroke adjustable cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the stroke adjustable cylinder, so that the stroke adjustable cylinder can not accurately and stably stop in a certain position of the stroke adjustable cylinder, so it is one of the main indicators of the stroke adjustable cylinder.

The stroke adjustable cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the stroke adjustable cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The stroke adjustable cylinder is basically composed of stroke adjustable cylinder and stroke adjustable cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

Regular maintenance of the stroke adjustable cylinder includes: regular tightening, stroke adjustable cylinder fastening screws and gland screws, stroke adjustable cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the stroke adjustable cylinder once a year. Clean regularly, the stroke adjustable cylinder is cleaned every other year, and the seals are replaced while cleaning.

Answers to some questions about stroke adjustable cylinder:

How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.

What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.
