This article mainly introduces:

Korea hydraulic cylinder,lifting column cylinder manufacturer,lifting column cylinder

(Korea lifting column cylinder,produced by Hengyu Group）

lifting column cylinder are widely used in Korea，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed lifting column cylinder for customers from Korea.

Introduction to lifting column cylinder:

The definition of the minimum stable speed refers to the minimum movement speed of the lifting column cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the lifting column cylinder that undertakes different work has different requirements for the minimum stable speed.

Factors that should be considered when selecting the oil seal in the lifting column cylinder: some specific factors should be taken into account when selecting the oil seal in the lifting column cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: lifting column cylinder diameter, piston rod diameter, piston rod and piston groove size, lifting column cylinder working pressure, lifting column cylinder movement speed, hydraulic system oil temperature and lifting column cylinder working environment.

If it is found that the lifting column cylinder lubrication is poor or the lifting column cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the lifting column cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the lifting column cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the lifting column cylinder center line. In this way, when the piston works in the lifting column cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the lifting column cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

lifting column cylinder buffer valve inspection and maintenance: For the valve buffer lifting column cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

Answers to some questions about lifting column cylinder:

Is a hydraulic cylinder and a jack the same thing?
Strictly speaking, no. Although the hydraulic principle is used, and even some of the longer jacks are similar to the cylinder, the internal structure of the two is different. There is a check valve inside the jack. After the top lift, the check valve locks the hydraulic oil circuit, and the hydraulic oil only enters and does not exit after the check valve locks, and can be lowered to complete a reciprocating movement. The cylinder is usually connected to the distribution tube to control the movement, and works with a wide variety of distribution valves and distribution systems according to different needs. The jack only needs a simple check valve.

How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.
