Analysis of the reasons: there is air in the pump body or inlet gas, or the bottom valve is not strict irrigation water is not satisfied with the vacuum pump filling a serious leak, gate valve or beat the door closed lax. Solution: First water pressure, and then filled with water pump, and then boot. At the same time check the check valve is tight, piping, fittings leaks, such as found leakage, remove the joint at the joints coated with oil or paint, and tighten the screws. Check the pump shaft seal ring, such as serious wear and tear should be replaced with new pieces. Piping leaks or leaks. Nuts may not be tightened during installation. If the leakage is not serious, can be smeared in the place of leakage or leakage of cement, or coated with asphalt mixture of cement slurry. Temporary repair can be painted wet mud or soft soap. If the joint leaks, you can use a wrench to tighten the nut, such as serious leakage must be re-disassembly, replacement of cracked pipe; reduce the head, the pump nozzle into the water pressure above the pump caused the common cause of the failure, Not all reasons, in practice to deal with failure, due to the actual analysis, should follow the principle of first outside, should not blindly operate or contact professionals.
The main features of the dust seal is sealed outside dust, in addition, the use of dustproof seals and Piston Rod Seals , seal ring ring combination punching system can also
prevent the oil film blowing, because these two characteristics (remove dust and oil scraping) is contradictory each other, because of this choice before the dust seal is important
to distinguish the characteristics of each kind of application is a priority, special performance is not the same, as the dust seal type, so if we keep the cylinder of the oil film is
more important,
It has excellent sliding properties, deformation compensation piston rod or piston, scraping the lateral pollutant effect is very good, even the cohesive soil, the hydraulic medium
very good compatibility, no viscosity, no creeping, compact structure, saving installation space, from the inner side of scraping attachment residual oil film the surface of the
piston rod of the effect is very good.Used in hydraulic cylinder, general machinery hydraulic cylinder of exposed dust proof
