How to improve self-absorption time and capacity of combustion engine oil pump

1. The discharge valve must be opened and activated

Burner oil pump suction tube gas, relying on the combustion pump started pumping away, it must open the valve to start, so that gas can be discharged from the discharge port.

2. Burner oil pump cavity to have sufficient liquid

ZYB burner pump chamber if there is no liquid, you can not form a gas-liquid foam mixture, it can not be aspirated. Burning too little pump cavity also can not play the role of suction.

Experiments on a ZYB burner oil pump show that its pumping capacity is closely related to the amount of liquid in the pump. When the combustion oil pump liquid less than 1.5L, the vacuum is very small, and the pump instability, the air will leak into the pump, the cycle will be interrupted, can not be continuously extracted; pump germanium water is greater than 2.OL Back to block the tongue under the tongue, the air will not leak into the pump,

At this time began to smoke continuously. The degree of vacuum increases as the amount of fluid in the pump increases. When the burning oil pump liquid volume up to 3.5L, the vacuum up to 9m; when the liquid volume is greater than 3.5L, the degree of vacuum increases with the increase in the amount of liquid storage slowed down, it seems its stock solution The most appropriate amount of 3.5L.

In order to ensure the speed and reliability of extraction, a sufficient amount of liquid should be filled in the pump chamber before starting.

Burning pump at different speeds of self-suction vacuum degree, the speed n of self-suction vacuum greatly affected until it reaches the limit of the vacuum when the speed of the influence was weakened. The pump should self-priming the prime mover speed to high speed, in order to shorten the self-priming time.
