How to determine whether hydraulic leak of hydraulic cylinders, the first thing you should consider using the relevant series of standard hydraulic cylinders, so do have a lot of benefits. First, can greatly shorten the design and manufacturing cycle fuel tanks, followed by convenient spare parts, and standard hydraulic cylinders have greater interchangeability and versatility. Also 630T cylinder, standard hydraulic cylinders in the design have conducted thorough analysis and calculation, carried out the work bench and field tests, plus there are a professional factory production equipment, steel and more perfect test conditions able to ensure the quality, so use more reliable. Hydraulic cylinders in use often leak, how to check the hydraulic cylinder for leaks it? Here we take a look at the analysis: If the cylinder oil continuously from the back end of the outflow pipe apart and large, indicating that the hydraulic cylinder vent serious. Run to the hydraulic cylinder piston rod has a top chamber, open the hydraulic cylinder return pipe, blocking the return pipe ends to prevent reverse flow total return pipe. Then start the engine, the boom has been placed in the hydraulic cylinder piston rod lever raised position. Piston hydraulic cylinder piston works only one-way movement, the movement in the opposite direction from the force required to complete. But its stroke hydraulic cylinder piston generally more big. Hydraulic cylinder piston rod can be divided into single and double rod two structures fixed by way of fixed and fixed two cylinder piston rod, according to the role of fluid pressure in the case of a single-acting and double-acting. In a single-acting hydraulic cylinder, the pressure oil chamber is for a hydraulic cylinder, by hydraulic pressure of the cylinder to achieve a single direction of movement, the movement in the opposite direction by an external force (e.g. spring force, its own weight or external loads, etc.) to achieve; and bis acting hydraulic cylinder piston movement in both directions through the two chambers alternately into the oil, by the action of hydraulic pressure to complete. Single-pole double-acting hydraulic cylinder piston. There is only one side of the piston rod, and thus the effective role of different areas of the two chambers. In the fuel supply amount is the same, different customized cylinder into the oil chamber, the piston velocity is different; different in supply pressure to overcome the force of the same load, different chamber into the oil, the desired, or after it is set in the system pressure , sanitation garbage truck hydraulic cylinder movement in both directions to overcome load force 630T different cylinders, Gannan Tibetan Autonomous Prefecture, cylinders, hydraulic speed quality offered by mass-velocity Dezhou City, hydraulic machinery factory.
