How to improve the self absorption time and ability of self

1 must open the discharge valve to start
The gas in the suction pipe of the suction pipe is to be drawn away from the suction pump, so that the gas can be started and the gas can be discharged from the discharge port.
2 self suction pump chamber to have a sufficient amount of liquid
If there is no liquid in the cavity of the suction centrifugal pump, it can not form a mixture of gas and liquid. Since the suction pump cavity is too small can also play a role in pumping gas.
The experiment of a self suction centrifugal pump shows that the pumping capacity is closely related to the number of liquid in the pump. When the pump is less than 1.5L when the liquid, the vacuum is very small, and the working condition of the pump is not stable, the air will leak into the pump, the cycle will be interrupted, can not be continuous pumping gas; pump germanium content is greater than 2.OL, the back of the tongue, the air will not leak,
At this time began to smoke. The vacuum degree increases with the increase of the amount of the liquid in the pump. When the self suction pump diamond fluid amounted to 3.5L, vacuum degree up to 9m; liquid storage amount greater than 3.5L, vacuum degree were increased with the increase of liquid reserves slowed down, as shown in Figure 2-15. From this view, the 3.5L of the reservoir is the most appropriate.
In order to guarantee the speed and reliability of the pumping gas, the liquid in the pump chamber should be poured into the pump chamber before starting.
Self suction pump at different rotational speed of the vacuum degree, the speed of the N on the vacuum degree of the impact is very big, until close to the limit of the speed of the impact will be weakened. Pump in the self absorption should be the original motive speed to the high-speed, in order to shorten the time of self absorption.
