(New Zealand boarding axle cylinder,produced by Hengyu Group）

boarding axle cylinder are widely used in New Zealand，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed boarding axle cylinder for customers from New Zealand.

Introduction to boarding axle cylinder:

The definition of the minimum starting pressure of the boarding axle cylinder refers to the minimum working pressure of the boarding axle cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the boarding axle cylinder parts and the size of the sealing friction.

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

If the boarding axle cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the boarding axle cylinder. The internal parts of the boarding axle 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 boarding axle 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 boarding axle 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 boarding axle cylinder bore processing is out of whack. Because the piston and boarding axle cylinder, guide rail and piston rod are relative If the boarding axle 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 boarding axle cylinder weight composition and calculation. The weight of the boarding axle cylinder is composed of the boarding axle cylinder diameter, the outer diameter and weight of the boarding axle 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.

At the rated pressure, the thrust of the boarding axle cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the boarding axle cylinder is related to the diameter of the boarding axle cylinder, but not to the stroke of the boarding axle cylinder. Moreover, the larger the boarding axle cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the boarding axle cylinder.

Answers to some questions about boarding axle cylinder:

How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.

What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.
