Roadside Assistance needs wrecker, tells you how to exclude leakage of hydraulic system

Hubei Changjie Special Purpose Vehicle Co., Ltd. to introduce you wrecker hydraulic system: is fragmented wrecker energy transmission piecemeal, is the way wrecker body blood vessels. Wrecker hydraulic pressure piecemeal tasks and device status are different, but the same utterly optional hydraulic assembly, followed by the fuel tank, hydraulic oil, roller pump, all kinds of hydraulic motors, multi-valve, hydraulic cylinders, hydraulic tubing, offset valve, hydraulic lock. Forming a hydraulic leak scene often piecemeal from joints, joints, skin and other dense books range results, but there are also multi-range coupling means quality hydraulic components, hydraulic oil quality of their own performance, pipeline, hydraulic fragmented vision, use and protection of results.
      Years of production experience, wrecker truck hydraulic oil spills often fragmented scene can judge from the following ten aspects:
    1, from the hydraulic envisaged, the guide sleeve, the cylinder, the piston rod of one mind often emerge officers without proper; state under tension load moment pressure is too high, lower thrust form the back pressure is too high, beyond the tasks envisaged cylinder power;
      2, the guide sleeve O-ring mold is suppressed parts, there is a parting line for the positioning device, but the emergence of the scene when the device is misplaced;
      3, the hydraulic cylinder surface not to force, radial force have chosen to load acts between the piston rod and guide, the late oil seal wear operation;
      4, there is no accurate seal selection, poor quality, there is no accurate means, the amount of ambient conditions in which the piston rod is high, heat radiation so slow aging seals;
      5, the hydraulic hose assembly is withhold joints, buckle pressure is too large, the inner layer hose damage;
      6, hydraulic hose assembly is withhold joints, not withholding enough strength to form oil leakage, oil spills and pull off;
       7, was under repeated pressure pulses, coat bounce, withhold efforts to reduce the formation permeability, oil spills and pull off;
    8, there is no standard connector precision machining, forming the interface oil spills, oil leakage;
      9, there is no accurate way to use, the use of shock after the formation of tubing increased life expectancy;
    10, is serving a fragmented set of hydraulic pipe inferior, poor quality rubber, wire tension more than layers, woven wall thickness are not carrying more than the power, the power of low pressure, the use of short life expectancy, are under pressure oil strikes, easy to form a wrecker pipeline leakage protection.
