Model Description GY-A6V1-2 variable pump series - Technical Data Model Description GY-A6V1 -2 variable pump series - Technical data hydraulic pump overheating excessive heat pump maintenance for two reasons, one is mechanical friction and heat. Since moving surfaces in dry or semi-dry friction state friction, friction between the moving parts of the heat. The second is a liquid friction and heat. High pressure oil leak to the low pressure chamber through a variety of gap, a large number of hydraulic energy into heat energy loss. Therefore, the correct choice of the gap between moving parts, fuel tank capacity and cooler domestic pump, the pump can prevent excessive heat and high oil temperature phenomenon. Also, back to the oil filter blockage caused by excessive back pressure back to the oil, the oil temperature is too high and can cause the pump to overheat. 7. Piston oil spill 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) too small and too long pump drain line sales, so that the seal leakage; (4) external pump tubing loose fittings injury, the gasket aging or cracks; (5) variable adjustment mechanism bolts loose, broken seals; ( 6) Cast iron pump casing adverse trachoma or welding.
