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

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

Introduction to stroke adjustable cylinder:

How to repair the stroke adjustable cylinder body when it is damaged: When the stroke adjustable cylinder has trace deformation and shallow tensile marks, the stroke adjustable cylinder is repaired by strong honing process. The heavy honing process can repair stroke adjustable cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the stroke adjustable cylinder can meet the technical requirements.

At the rated pressure, the thrust of the stroke adjustable cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the stroke adjustable cylinder is related to the diameter of the stroke adjustable cylinder, but not to the stroke of the stroke adjustable cylinder. Moreover, the larger the stroke adjustable cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the stroke adjustable cylinder.

The wear of the hard chromium plating layer of the stroke adjustable cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

Causes and countermeasures of oil stroke adjustable cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the stroke adjustable cylinder will lead to premature wear of the piston seal, replace the piston seal; If the stroke adjustable cylinder is visibly scarred, the stroke adjustable cylinder must be replaced. It can be pressurized at one end of the stroke adjustable cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most stroke adjustable cylinder piston drift may not come from the stroke adjustable cylinder, the above method to determine the stroke adjustable cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

Answers to some questions about stroke adjustable cylinder:

How to design the guide sleeve of cylinder diameter 400?
The purpose of the guide sleeve is to guide and seal. Therefore, it is necessary to look at the speed of the piston rod, working pressure and radial force. High speed, medium pressure, no (or very little) radial force, with a Steseal. Low speed and heavy load, medium radial force, combined seal. High speed and heavy load, large radial force, sealed with DU sleeve + copper ring + combination. The combination seal must have a lubricating oil passage, and a seal must be added to the outside of the oil passage.

How does the clamping cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, The executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, The control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, The auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.
