(Finland supporting cylinder,produced by Hengyu Hydraulic Cylinder Factory）

supporting cylinder are widely used in Finland，because of high work efficiency，long service life，smooth movement.So our company has designed supporting cylinder for customers from Finland.

Introduction to supporting cylinder:

The main role of the supporting cylinder: the supporting cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the supporting cylinder realizes reciprocating motion. The structure of the supporting cylinder has three categories: piston supporting cylinder, plunger supporting cylinder, swing supporting cylinder, piston supporting cylinder and plunger supporting cylinder to achieve reciprocating linear motion, output speed and thrust, swing supporting cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the supporting cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The supporting cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

The wear of the hard chromium plating layer of the supporting 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.

The repair method of supporting cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.

supporting cylinder buffer valve inspection and maintenance: For the valve buffer supporting 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 supporting cylinder:

How to calculate the speed of cylinder weight decline?
To reduce the weight of the cylinder, the necessary condition is that the weight of the piston rod + external load is greater than the friction between the seal ring and the cylinder. There are many reasons for this, first of all, consider the reasons of the cylinder itself, the piston in the cylinder and the sealing ring on the piston rod will play a reaction force on the weight of the cylinder (because of friction), which depends on the tightness of the sealing ring and the cylinder. Secondly, what is connected under the piston rod of the cylinder and how much weight there is. And the way the cylinders are arranged, is it completely vertical. Anyway, in fact, the most important thing is to see how much the bore of the oil hole of the piston rod cavity of your cylinder is. For example, if the hole in the lower chamber of the cylinder is small, as thin as a needle, then its descent rate will be slow.

How many kilograms can the 63 cylinder hold?
The force of the cylinder is related to the cylinder diameter and pressure. 63 cylinder diameter (cylinder inner circle diameter), 21MPA pressure, thrust 6 tons.
