The pump valve of the internal gear pump causes the engine oil supply to be poor and the solution

June 25, 2023

First of all, the oil supply of Botaibang pump industry can not keep up with the following aspects.

A. The fuel tank cap air valve and steam valve are blocked;

B. The fuel filter is clogged;

C. Gasoline pump damage: 1. Incoming and outgoing oil valve failure, 2. Diaphragm rupture, 3. The gap between the outer rocker arm and the inner rocker arm is too large;

D. The oil circuit system has air leakage, oil leakage, and the oil pipe is concave or blocked;

E. There is oil in the tubing;

F. Have air resistance;

G. The carburetor inlet or filter is blocked;

H. The carburetor oil passage is blocked or the oil inlet needle is stuck.

Internal gear pump solution:

A. Check if the tubing is cracked, if it is loose, if the tubing joint is loose or if the oil pump leaks oil;

B. Remove the carburetor connection tubing. Use the starter or hand crank to turn the engine to see if oil is ejected from the tubing. If not, the fuel tank and the gas pump are faulty. If so, the carburetor is faulty.

C. Remove the oil inlet pipe joint connected to the gasoline pump, and use the mouth to suck the oil. If it cannot be sucked out or it is very laborious, there is a problem with the fuel tank and the fuel filter;

D. Remove the oil inlet pipe joint connected to the fuel filter, and suck the oil with the mouth. If the suction is not strong or laborious, the fuel tank, the fuel tank cap and the oil outlet pipe have problems;

E. According to the inspection method of AD, it is inspected from the front to the back, and is excluded from the back to the front;

F. At present, in summer, the temperature is higher, and the gas generated by the evaporation of gasoline in the oil circuit will cause a certain oil supply in the oil pipe to fail to catch up. At this time, as long as the parking is closed, the air resistance disappears after cooling, the internal gear pump or the loose oil pipe Release the gas;

G. If it is caused by the cause G, H or the main hole in the float chamber and each nozzle hole, it is enough to spray with the carburetor cleaner.

The above are the common reasons and solutions for the lack of acceleration, oil supply can not keep up, I hope to help you.
