Dominica shearing machine cylinder

(Dominica shearing machine cylinder,produced by Hengyu Group)

shearing machine cylinder are widely used in Dominica,because of excellent fatigue and impact resistance,smooth movement,powerful torque.So our company has designed shearing machine cylinder for customers from Dominica.

Introduction to shearing machine cylinder:

If the shearing machine cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the shearing machine cylinder. The internal parts of the shearing machine cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the shearing machine cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the shearing machine cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the shearing machine cylinder bore processing is out of whack. Because the piston and shearing machine cylinder, guide rail and piston rod are relative If the shearing machine cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling shearing machine cylinder weight composition and calculation. The weight of the shearing machine cylinder is composed of the shearing machine cylinder diameter, the outer diameter and weight of the shearing machine cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

We can not just consider the price and ignore the quality when we purchase the shearing machine cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the shearing machine cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the shearing machine cylinder is not required.

The viscosity of the working oil used in the shearing machine cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

When the shearing machine cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the shearing machine cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

Answers to some questions about shearing machine cylinder:

How to use a solenoid valve to control the expansion of a cylinder? Doesn't the solenoid valve only control on/off?
Use the solenoid valve P into A-B (generally equipped with oil circuit board) to connect the oil inlet interface at both ends of the cylinder, and the solenoid valve can be realized by power off (refer to the solenoid valve 2B2L, different solenoid valve actions are different).

What causes hydraulic cylinder oil leakage?
1. Internal leakage (1) The wear ring on the piston is seriously worn, leading to friction between the piston and the cylinder liner, and finally strain the cylinder liner, piston and seal; 2) Seal long-term use failure, piston seal (mostly U, V, Y ring, etc.) aging; 3) The hydraulic oil is dirty, and a large number of impurities enter the cylinder and wear the piston seal to bad; 2. External leakage 1) cylinder inlet and outlet tubing joint cracking; (This I see in the actual work is still more) 2) The piston rod extension end with the piston rod seal damage, mostly due to the piston cylinder is caused by hair, but also caused by aging; 3) The seal between the extended end of the piston rod and the liner is damaged.
