Thailand shearing machine cylinder

(Thailand shearing machine cylinder,produced by Hengyu Hydraulic Co., Ltd)

shearing machine cylinder are widely used in Thailand,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed shearing machine cylinder for customers from Thailand.

Introduction to shearing machine cylinder:

If the shearing machine cylinder slips or crawls, please check whether there is astringency inside the shearing machine cylinder, because the internal parts of the shearing machine cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the shearing machine cylinder changes with the different stroke position, and the slip or crawl occurs. 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.

The shearing machine cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the shearing machine cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

When the long-stroke shearing machine cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in shearing machine cylinder head seal damage, oil leakage, and piston sleep in the shearing machine cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the shearing machine cylinder; The piston and the piston rod are connected with a spherical joint.

Answers to some questions about shearing machine cylinder:

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.
