(Canada vehicle hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

vehicle hydraulic cylinder are widely used in Canada，because of no transmission clearance，simple structure and reliable operation，excellent temperature resistance.So our company has designed vehicle hydraulic cylinder for customers from Canada.

Introduction to vehicle hydraulic cylinder:

When the vehicle hydraulic cylinder is in use, ensure that the vehicle hydraulic cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

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

vehicle hydraulic cylinder body inspection: The inner surface of the vehicle hydraulic cylinder and the piston seal are the main factors causing the leakage in the vehicle hydraulic cylinder, if the vehicle hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the vehicle hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

The daily inspection of the vehicle hydraulic cylinder includes: checking the connection of the vehicle hydraulic cylinder and the pipe joint for leaks. Check the vehicle hydraulic cylinder rod for leaks. Check the vehicle hydraulic cylinder connection for leaks. When the vehicle hydraulic cylinder moves, the work is normal and smooth. Whether the vehicle hydraulic cylinder has internal leakage.

Answers to some questions about vehicle hydraulic cylinder:

The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.

Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.
