(Belarus stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to stroke adjustable cylinder:

Disassembly stroke adjustable cylinder: When disassembly stroke adjustable cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the stroke adjustable cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the stroke adjustable cylinder.

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.

stroke adjustable cylinder use should try to avoid sealing belt into the stroke adjustable cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the stroke adjustable cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the stroke adjustable cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

The piston seal of the stroke adjustable cylinder is the main element to prevent leakage in the stroke adjustable cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

Answers to some questions about stroke adjustable cylinder:

How to change the seal ring of lift oil cylinder of forklift truck?
Remove the cylinder, put it on the vise, first screw off the big nut plug on the head, and then pull out the guide sleeve, you can directly pull out the core of the cylinder, if it is to change the seal of the cylinder head, the core does not need to be pulled out, if it is to change the seal inside, pull it out and see the oil seal, remove it and replace it, there are three seals of the cylinder head, the inner seal, The outer seal, dustproof, it is best to replace them all together, and be sure to keep them clean when changing, and you can lubricate them with clean hydraulic oil.

What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.
