Nepal hydraulic cylinder,yg series hydraulic cylinder manufacturer,yg series hydraulic cylinder
(Nepal yg series hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
yg series hydraulic cylinder are widely used in Nepal，because of long service life，smooth movement，high work efficiency.So our company has designed yg series hydraulic cylinder for customers from Nepal.
The definition of the minimum starting pressure of the yg series hydraulic cylinder refers to the minimum working pressure of the yg series hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the yg series hydraulic cylinder parts and the size of the sealing friction.
The yg series hydraulic cylinder is not the same as the yg series hydraulic cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the yg series hydraulic cylinder can not be used as a high-power power component, but the yg series hydraulic cylinder can be used as a relatively large power component, or the yg series hydraulic cylinder system can be used.
The scar on the sliding surface of the yg series hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the yg series hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.
If the yg series hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the yg series hydraulic cylinder. The internal parts of the yg series 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 yg series 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 yg series 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 yg series hydraulic cylinder bore processing is out of whack. Because the piston and yg series hydraulic cylinder, guide rail and piston rod are relative If the yg series 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 yg series hydraulic cylinder weight composition and calculation. The weight of the yg series hydraulic cylinder is composed of the yg series hydraulic cylinder diameter, the outer diameter and weight of the yg series 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 superimposed hydraulic control valve is added to the bottom of a solenoid valve and a double directional throttle valve, why does the cylinder shock on the return trip?
The stack hydraulic control check valve must be added above the stack one-way throttle valve.
How many tons is the oil cylinder 16mpa?
It depends on the cross-sectional area of the cylinder A(mm2)F=16mpa×A unit is (tons).
