Engineering hydraulic cylinders, hydraulic power Lu (certified), Nanping hydraulic force provided by the Texas Lu hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is specialized in "jacks, electric pumps, hand pumps, cylinders," the business, the company adhering to the "honesty, hard service" concept, to provide you with the highest quality products and service. Welcome to inquire! Contact: Lu Jingli. If the fuel tank vent valve is set, you can look at pipe joints loose, and then do a few actions to exhaust. But pay attention to fuel injection, if the cylinder pressure joints, the selection pressure joints are more secure because it is easy to operate, in general, the best in the high exhaust standard hydraulic cylinders, this effect is better. If neither of the cylinder, exhaust operation can be performed, the specific operation is: let the piston rod moves to one direction, pause a few times, and then it moves to the other direction, then pause some time, so repeated non-standard hydraulic cylinders, you can drain the air in the cylinder. (4) before and after unloading unloading to try to create conditions to prevent the hydraulic cylinder parts are contaminated dust and impurities around. For example, as far as possible should be demolished in a clean environment; After disassembly all parts use plastic sheeting to cover, do not use cotton or other work with a cloth cover. (5) after the demolition of the hydraulic cylinder hydraulic cylinder to carefully check to determine which parts can continue to use, what parts can be repaired before use, which parts must be replaced. (6) must be carefully cleaned before assembly of the parts. (7) around the sealing device to be installed correctly. ① When installing the O-ring, do not pull its permanent deformation degree, do not side scrolling side suit hydraulic engineering, otherwise it may cause the formation of distorted shape and oil spills. ② When installing Y-shaped and V-ring, pay attention to the mounting direction, but avoid loading oil spill. Y-shaped ring, its lips coping with the oil pressure chamber; in addition, Yx-ring Note also distinguish shaft or hole, do not install the wrong. V-ring shape different from the support ring, sealing ring and pressure rings, when the pressure ring compression seal ring, seal ring bearing ring can be generated as shaped sky seal, the sealing ring should be installed facing opening pressure oil chamber; adjust the pressure ring should be limited so as not to leak, not too tight, to prevent seal resistance is too large. ③ sealing device such as a tie with the sliding surface, the assembly should be coated with an appropriate amount of hydraulic oil. O-ring seals and dust all the new ones should ④ disassembled.
