In the design and processing sectors should take full account of the important factors affecting the leaking seals in the design and processing. American Association of Automotive Engineers (SAE) recommended the following two ports to prevent leakage of solution. ①SAE straight thread "O" ring ports: sealed by "O" rings, connected by straight thread; ②SAE4 bolted flange: for larger port. In addition, the choice of the seal is also very important, roughness usually static seal the sealing surface of the table Ra3.2 ~ Ra1.6 Road mixing machine hydraulic maintenance, dynamic sealing surface Ra0.8 ~ Ra0.4. If the factors are not fully taken into account the initial leak, will bring incalculable loss to the future production of porous leaking hydraulic components in a variety of cover, due to the effect of surface roughness, can not completely contact between the two surfaces Road mixing machine hydraulic repair factory, the two surfaces are not in contact microscopic depressions road mix hydraulic maintenance Which is good, the formation of many cross-sectional shape and diverse, ranging from the size of the gap, cross-sectional dimensions and surface roughness of voids. Multi gap leak, the liquid flows through the bending required numerous voids road mix hydraulic maintenance fees, doing sealing performance test, subject to certain dwell time, the leakage can be revealed.
