Assembly aspect. Front hydraulic system assembly, test pressure should push performance machine components repair shop, check whether the elements of each combination of surface leakage outside, if there is leakage, it should take appropriate action. Only when all the elements are not leaking does not leak before they can formally put into the system. Hydraulic components and hydraulic systems during assembly, to conduct rigorous cleaning, deburring, in addition to welding slag, and the necessary anti-corrosion treatment, assembly process in strict accordance with the requirements for assembly, to eliminate the gap caused by distortion due to assembly and burrs, welding slag and rust, etc gap formed abrasive. Power leakage on the sealing surface of the rotating shaft, if left spiral machining marks, when the shaft is rotated, the liquid under the action of the rotating shaft rotational force of the spiral flow along the groove marks. If the direction of rotation of the spiral marks the direction coincides with the axis of the push shop maintenance costs, since the coil traces "pumping" effect pushing repair shop Which is good, it will have power leakage. Leakage power is characterized by higher shaft speeds push shop machine repair factory, the greater the amount of leakage. Prevent power leakage, should avoid the presence of 'pumping' effect on the sealing surface of the shaft and seal lip machining marks or leakage power using the principle, the use of screw pump oil traces the role of the pump will leak back to prevent leakage.
