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. Additionally Road mixing machine hydraulic maintenance, seals choice is very important, roughness usually static seal the sealing surface of the table Ra3.2 ~ Ra1.6, dynamic sealing surface Ra0.8 ~ Ra0.4. If you do not take full account of the initial leak of factors will bring incalculable damage to future production in the foot stationary central axis of the load should move cylinder concentric neutral force, in order to avoid lateral forces road mixing machine hydraulic maintenance production, lateral force tends to seal wear and piston damage. Of the cylinder and the cylinder when moving object moving objects installed parallel road mix hydraulic maintenance Which is good in the direction of movement of the rail surface, which is parallel to the degree usually not more than 0.05mm / m. Installation of hydraulic cylinder gland screws, tighten them level to ensure the full stroke of the piston can move freely, without arrest and the severity of the phenomenon of uneven appropriate. Screws too tight, it will increase the resistance Road mixing machine hydraulic maintenance fees, accelerated wear; too loose can cause leakage. Exhaust valve or exhaust Prather hydraulic cylinder or exhaust vent must be installed at the highest point Prather, so as to exclude air.
