Bangladesh hydraulic cylinder,cargo elevator hydraulic cylinder manufacturer,cargo elevator hydraulic cylinder(Bangladesh cargo elevator hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
cargo elevator hydraulic cylinder are widely used in Bangladesh,because of long service life,smooth movement,high work efficiency.So our company has designed cargo elevator hydraulic cylinder for customers from Bangladesh.
Regular maintenance of the cargo elevator hydraulic cylinder includes: regular tightening, cargo elevator hydraulic cylinder fastening screws and gland screws, cargo elevator hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the cargo elevator hydraulic cylinder once a year. Clean regularly, the cargo elevator hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.
When the piston speed of the cargo elevator hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the cargo elevator hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
If the cargo elevator hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the cargo elevator hydraulic cylinder. The internal parts of the cargo elevator 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 cargo elevator 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 cargo elevator 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 cargo elevator hydraulic cylinder bore processing is out of whack. Because the piston and cargo elevator hydraulic cylinder, guide rail and piston rod are relative If the cargo elevator 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 cargo elevator hydraulic cylinder weight composition and calculation. The weight of the cargo elevator hydraulic cylinder is composed of the cargo elevator hydraulic cylinder diameter, the outer diameter and weight of the cargo elevator 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.
When the cargo elevator hydraulic cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the cargo elevator hydraulic cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.
Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.
What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.
