Pakistan hydraulic cylinder,tailplate hydraulic cylinder manufacturer,tailplate hydraulic cylinder(Pakistan tailplate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
tailplate hydraulic cylinder are widely used in Pakistan,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed tailplate hydraulic cylinder for customers from Pakistan.
The wear of the hard chromium plating layer of the tailplate hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
Regular maintenance of the tailplate hydraulic cylinder includes: regular tightening, tailplate hydraulic cylinder fastening screws and gland screws, tailplate 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 tailplate hydraulic cylinder once a year. Clean regularly, the tailplate hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.
If the tailplate hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the tailplate hydraulic cylinder. The internal parts of the tailplate 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 tailplate 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 tailplate 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 tailplate hydraulic cylinder bore processing is out of whack. Because the piston and tailplate hydraulic cylinder, guide rail and piston rod are relative If the tailplate 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 tailplate hydraulic cylinder weight composition and calculation. The weight of the tailplate hydraulic cylinder is composed of the tailplate hydraulic cylinder diameter, the outer diameter and weight of the tailplate 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.
If the tailplate hydraulic cylinder slips or crawls, please check whether there is astringency inside the tailplate hydraulic cylinder, because the internal parts of the tailplate hydraulic 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 tailplate hydraulic cylinder changes with the different stroke position, and the slip or crawl occurs.

For example, the piston is different from the piston rod or the piston rod is bent, the tailplate 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.
Do the collecting cylinder, distributing cylinder and distributing cylinder on the organic heat carrier boiler need to be notified separately as the pressure vessel for construction?
Do not need to be installed as a separate pressure vessel to inform, according to the organic heat carrier boiler can be informed. Write a "special equipment installation, renovation and maintenance notice" issued on it.
Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.
