(Belarus limit position hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

limit position hydraulic cylinder are widely used in Belarus，because of excellent fatigue and impact resistance，long service life，simple structure and reliable operation.So our company has designed limit position hydraulic cylinder for customers from Belarus.

Introduction to limit position hydraulic cylinder:

When installing the limit position hydraulic cylinder, the axial ends of the limit position hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the limit position hydraulic cylinder, there is axial expansion. If the two ends of the limit position hydraulic cylinder are fixed, all parts of the limit position hydraulic cylinder will be deformed. When disassembling the limit position hydraulic cylinder, it is strictly forbidden to hammer the limit position hydraulic cylinder and the piston surface, such as the limit position hydraulic 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.

When the limit position hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The limit position hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the limit position hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil limit position hydraulic cylinder should not be in direct contact with water vapor for a long time. The limit position hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the limit position hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the limit position hydraulic cylinder Before working, the limit position hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the limit position hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

How to repair the limit position hydraulic cylinder body when it is damaged: When the limit position hydraulic cylinder has trace deformation and shallow tensile marks, the limit position hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair limit position hydraulic 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 limit position hydraulic cylinder can meet the technical requirements.

limit position hydraulic cylinder use should try to avoid sealing belt into the limit position hydraulic 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 limit position hydraulic 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 limit position hydraulic 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.

Answers to some questions about limit position hydraulic cylinder:

What is a mold core cylinder?
Simple plastic parts can be directly pushed out by the ejector rod after injection molding, complex plastic parts can not be directly pushed out by the ejector rod after injection molding, to make the interference part active, control its position through the cylinder (injection molding into the mold, so that the shape of the plastic parts meet the demand, exit after opening the mold, so that the plastic parts are smoothly pushed out), This kind of cylinder is the mold core cylinder.

What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.
