Kawasaki K3V Series Hydraulic Piston Pump

Kawasaki K3V series hydraulic piston pump, because the inner parts of the pump adopts modern advanced surface wear-resistant coating technology, the service life of the pump has been greatly improved. The features of advanced performance, reliable work and convenient maintenance are widely used in various construction machinery. Now the Japanese "Kobelco", "Sumitomo" and "Kato" brand excavators all use this series of pumps. The designed service life of the pump variable mechanism is 10,000 hours. However, when the metal particles in the hydraulic fluid exceed the standard seriously, the oil erosion and wear in the gap of the internal components of the pump variable machine will cause the cooperation gap between the variable piston and the stem and the hole The servo pressure oil leaks into the pump casing from the gap between the valve stem and the hole. When the leakage in the variable mechanism is serious, the variable fork lever cannot be pushed to the fixed position without reaching the standard servo pressure oil, so that the total output of the pump The power is reduced, and when repairing the pump, only focus on repairing the inner liner of the pump or replacing the inner liner, and not paying attention to checking the internal leakage of the variable mechanism of the pump, so the repaired pump is often more efficient. To the ideal school results.
