3.5L/M flow mini water pump/pressure washer pump with self-priming function

Judging the working condition of exhaust end of miniature pump

The above problem is to discuss the suction end resistance of the pump. According to these conditions, the range of selection has been reduced, but the problem of exhaust end resistance must be considered. In this way, the optional range can be determined.

In practical application, the exhaust condition of the micro vacuum pump is different: one is that the exhaust is very smooth and goes straight to the atmosphere; the other is the high exhaust resistance, such as valves, small bends, and large damping sensors on the exhaust pipe road, Non-specific silencers, exhaust below liquid level, gas to airtight or semi-closed containers, etc. In modern design and manufacture, the micro vacuum pump with different exhaust conditions is treated differently. " The parameter of the maximum resistance Por value "is to calibrate the exhaust capacity of the pump, so we can use strict technical means to determine whether the type selection is appropriate or not."

Working principle:The rotary motion of the motor makes the driving gear to rotate and the driving gear makes the driven gear to rotate.When the meshing teeth gradually separate on one side of the suction chamber; suction chamber volume is increased; pressure is reduced, the liquid in suction pipe will be sucked into pump. Sucked liquid was divided into two road in gear teeth groove and was pushed to the discharge chamber. After liquid entering into the discharge chamber, because of the two gear tooth meshing unceasingly, the liquid from the discharge chamber into the discharge pipe by extrusion.
