What is the reason for the steering oil leakage in the sprinkler truck?
1 The spillage of the bottom cover of the sprinkler is mostly caused by the casting, so that the cover plane is uneven or the hole of the conduit is not perpendicular to the two planes, resulting in rigorous riveting or deflection of the conduit. For this type of oil leakage, the plane and holes or conduits should be reworked.
The two bottom holes of the worm gear box and the inside of the box are unobstructed, and the screw holes leak oil. Because the screw hole of the original machine is drilled through, or the screw hole is topped or top cracked by the longer screw during the warranty, the oil in the box penetrates outward along the thread. When this happens, it should be sealed by adding a fiber or pad to the root of the bolt.
3 gasket leakage is often due to the use of yellow paper. The strong adsorption of oil on the yellow paper, coupled with uneven bolt torque, the side cover, bottom cover deformation, the number of gaskets will be leaked if not adjusted. For this leakage, the gasket should be replaced with a immersed linerboard.
4 Oil leakage at the oil seal is generally caused by low quality of the oil seal, or the outer diameter of the oil seal and the looseness of the seat hole fail to reach an interference fit. The concentricity of the steering arm bearing hole and the oil seal bearing hole of the steering worm gear box is very poor, and the steering arm shaft seal Leaks. Or because the steering shaft is loose, the shaft diameter is out of round or conical and leaks. For this type of oil leakage, the method of updating the oil seal, renewing the bearing, grinding the shaft diameter, or updating the housing should be adopted.
Leakage in other parts of the 5 direction machine is due to metal cracks in the shell cracks, blisters, air holes, or screw holes, which is a drawback of accessories. For this type of oil leakage, conditions can be repaired, unconditional replacement parts should be.
