Hydraulic cylinders, hydraulic power Lu, Xi'an 200 tons 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. Single-acting hydraulic cylinder to pay attention to its reverse movement speed and magnitude of the force can not be controlled. Driven piston or plunger rod return since gravity movement, load force, the spring force must be greater than the back pressure and hydraulic cylinders and various parts of the frictional resistance of. Spring return hydraulic cylinders, springs have a certain role in space, its volume increases. Double-acting hydraulic cylinder to pay attention to its control system more complex than single-acting hydraulic cylinder. Single rod double acting hydraulic cylinder than double rod double acting hydraulic cylinder applications should generally some. Single rod hydraulic cylinders to be able to have a greater attention due to thrust piston rod, velocity returned there faster, so it is suitable to withstand loads in one direction while the load quickly returned to the occasion. Thicker rod, push and pull, the greater the difference between slow and fast. Double rod hydraulic cylinders work to pay attention to this range occupy a large space when its pump power range is equal to about three times the effective stroke length. Plunger hydraulic cylinder piston cylinder to pay attention to the size, weight was relatively large, horizontal installation, post cold pressed to one side, is likely to cause the seal and guide sleeve unilateral wear, so that the most suitable vertical piston-cylinder vertical installation use. (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, 200 tons of hydraulic cylinders, should be demolished as possible 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 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 their degree of permanent deformation of 200 tons of high quality hydraulic cylinders, do not scroll side edge suite 200 tons of hydraulic cylinders, or 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 200 t hydraulic cylinder manufacturers, to avoid oil spills installed instead. 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.
