Description

Saving type self priming tank

Technical Field

The utility model belongs to the technical field of the chemical industry, especially, relate to a saving type self priming jar.

Background

Centrifugal pumps are the most commonly used liquid delivery machines in chemical production. Before using the centrifugal pump, for avoiding taking place the gas and tie up the phenomenon, must use liquid earlier to irritate the pump, the effect of suction line bottom valve prevents just to irritate liquid before the start and flow out from the pump, but, to having the strong liquid of corrosivity, not only to pouring liquid in the pump very inconvenient, the one-way bottom valve is also corroded badly often moreover, takes place the bottom leakage phenomenon easily, consequently generally all uses the self priming jar at present to replace single-phase bottom valve. Fill with liquid in inhaling the jar certainly, after the starting pump, liquid is the suction in the self-priming jar, and gas phase space increases, and the pump starts the gas phase space ratio around, makes and produces the negative pressure in inhaling the jar certainly to through the pipette with the liquid in the storage tank inhale to the self-priming jar, get into the centrifugal pump by the liquid outlet again. But when the lowest liquid level of the liquid to be pumped is far lower than the center of the centrifugal pump or the density of the liquid is higher, the diameter and the height of the self-priming tank need to be increased; in addition to this, can increase the degree of difficulty of imbibition when increasing self priming jar height, need further increase self priming jar diameter.
