Uzbekistan hydraulic cylinder,plunger type cylinder manufacturer,plunger type cylinder(Uzbekistan plunger type cylinder,produced by Hengyu Group)
plunger type cylinder are widely used in Uzbekistan,because of clever hydraulic energy conversion,no transmission clearance,powerful torque.So our company has designed plunger type cylinder for customers from Uzbekistan.
When the plunger type cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the plunger type cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the plunger type cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the plunger type cylinder can meet the requirements by grinding. However, the life and reliability of this repair plunger type cylinder are not high.
1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.
The plunger type cylinder should be vented: when the plunger type cylinder is installed or parked for a long time to work again, the air will penetrate into the plunger type cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the plunger type cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the plunger type cylinder, the oil is best entered and discharged from the highest point of the plunger type cylinder. plunger type cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.
plunger type cylinder can not drive the load troubleshooting: oil pressure is too low. plunger type cylinder selection specifications are too small. Leakage in plunger type cylinder or associated hydraulic system element.
How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
How to determine the rated working pressure of the hydraulic cylinder?
Under normal circumstances, the working pressure is determined according to the size of the load and the installation space (the allowable diameter of the cylinder). In some special occasions, the smaller the cylinder, the better, the pressure level must be increased. The cylinder pressure is related to the estimated cost. The higher the pressure, the thicker the wall, the higher the cost, but conversely, the lower the pressure, the larger the diameter of the cylinder (when the same thrust) is required, the same high cost. Therefore, the rated pressure of the cylinder is concentrated in about 35 mpa, taking into account the cylinder diameter and wall thickness.
