Piston oil spill following main reasons: (1) the spindle shaft seal is damaged or defective scratch; (2) internal leakage is too large, resulting in increased pressure oil seal, and the seal damaged or out; 3) discharge Tubing too small for too long, so that the seal leakage; (4) external pump tubing loose electric radial piston pumps, fittings injury, the gasket aging or cracks; (5) variable adjustment mechanism bolts loose, broken seals; (6 iron pump) cast housing has bad blisters or welding. Troubleshooting insufficient pump flow problems (1) inhalation volume. The reason is that the suction piping resistance is too large or if less than oil. The pump's speed is too large, Texas radial piston pump, tank liquid level is too low, into the pipeline leak, Weifang radial piston pump, filter blockage. (2) excessive leakage. The reason is that the gap is too large pumps, seals caused by poor. As with the oil pan is metal fragments, iron and other scratches, face oil spills; variable mechanism in a one-way valve sealing surface with the bad, the bearing surface pump and oil pan or grind marks and other trachoma. Can determine the site of the pump is damaged by checking the hydraulic oil in the pump body mixed foreign matter. (3) inclined plate angle is too small, a small displacement of the pump, which need to adjust the variable piston, swash plate angle increases. rk-type radial piston pump | Weifang radial piston pump | hydraulic force provided by the Texas Lu Lu hydraulic equipment factory.
