The reasons and solutions of high pressure gear pump's oil can't keep up
High pressure gear pump with engine's oil can't keep up's reason in the following aspects:
1. The high pressure pump fuel tank cap air valve, steam valve blocked;
2. Gasoline filter plugging;
3. Gasoline pump damage: (1). Into or out of the oil valve failure, (2). Diaphragm rupture, (3). The rocker arm and in arm with large clearance between;
4. Leak oil system, oil spill, oil pipe touch concave or blocked;
5. Tubing in water;
6. High pressure pump started with faint and resistance;
7. High pressure pump carburetor inlet; Screen plugging; Oil passage blockage or feed needle valve card dead.
High pressure gear pump with engine's oil can't keep up's solutions shown below:1. The high pressure gear pump connection gasoline filter into tubing joint dismounting, with mouth oil absorption, if the suction out or very arduous, the gasoline tank, fuel tank cap, the tubing have a problem;
2. Would connect gasoline pump oil inlet joint dismounting, with mouth oil absorption, if the suction out or very arduous, the oil tank, gasoline filter has a problem;
3. Check the tubing whether have burst, concave flat, tubing joint is loose or pump leaks oil or not;
4. Let carburetor connecting tubing dismounting use starter or hand the rotation engine to observe whether there is oil from oil pipe extrusion or not, if not, the fuel tank and gas oil pump is faulty, if there is, the carburetor have fault;
5. High pressure gear pump as the above test procedure test from forepart to back end, eliminate it from the back end to forepart;
6. At present for the summer, the temperature is higher, the gasoline in the oil evaporation produce gas can lead to tubing in a period of oil supply does not follow to go up, at this time, as long as the stop to rest, to stay after cooling air resistance disappear, or unscrewing tubing gas can;
