(El Salvador stroke adjustable cylinder,produced by Hengyu Group）

stroke adjustable cylinder are widely used in El Salvador，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed stroke adjustable cylinder for customers from El Salvador.

Introduction to stroke adjustable cylinder:

The stroke adjustable cylinder should be vented: when the stroke adjustable cylinder is installed or parked for a long time to work again, the air will penetrate into the stroke adjustable cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the stroke adjustable cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the stroke adjustable cylinder, the oil is best entered and discharged from the highest point of the stroke adjustable cylinder. stroke adjustable cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

When installing the stroke adjustable cylinder, the axial ends of the stroke adjustable cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the stroke adjustable cylinder, there is axial expansion. If the two ends of the stroke adjustable cylinder are fixed, all parts of the stroke adjustable cylinder will be deformed. When disassembling the stroke adjustable cylinder, it is strictly forbidden to hammer the stroke adjustable cylinder and the piston surface, such as the stroke adjustable cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Before purchasing the stroke adjustable cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

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.

Answers to some questions about stroke adjustable cylinder:

What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.

What is a two-way hydraulic cylinder?
Bidirectional hydraulic cylinder definition: The bidirectional hydraulic cylinder uses the oil as the working medium, transmits the movement through the change of the sealing volume, and transmits the power through the pressure inside the oil. The two-way cylinder has at least two oil ports, which are used to connect the hydraulic tubing, and control the extension and retraction of the cylinder by pressing.
