The reason of oil spilling for road sweeper Facing the forty or fifty degrees high temperature weather outdoor, road sweeper oil seal is generally bacause road sweeping car oil seal damaged and sealing spring relaxation, exactly named the large amount of axial movement, is so-called shift pump oil. The way to solve the seal of road sweeper is generally with a sweeping car oil seal spring, such as road sweeper oil seal cup without damage. spring relaxation oil seal of road sweeper, loss of contractility. Spring then can be the road sweeper seal off, the spring "break apart, remove the appropriate length of Jin" in the spring at the end (about 3~5mm). Then the spring to loose screw and screw strength, the small end is screwed into the big end, and then used to rush rush jin. Trimmed, the spring return into the road sweeping car oil seal, can solve the oil leakage caused by spring relaxation. A large quantity of oil leakage caused by the axial movement. This will move back and forth. Have a look at whether the axial clearance is too large. If the amount of axial movement of the shaft. The end of an adjusting shim, shim thickness properly removed. If the end of the shaft is fixed screw loose screw, will be tightened. Such as seals the shaft end cover too thick, moderate thinning. If there are other reasons too much wear should be overhauled judgment should be excluded.
