A kind of automatic liquid filling centrifugal pump

Abstract

The invention belongs to the field of centrifugal pumps and particularly relates to an automatic liquid filling centrifugal pump. A pump body is included, and the left side wall of the pump body communicates with a water pumping pipe; a driving shaft is arranged on the right side wall of the pump body in a penetrating manner, and the portion, located in the pump body, of the driving shaft is sleeved with an impeller; the driving shaft can be made to rotate in a manner that belt transmission is adopted for the driving shaft or in a manner that the driving shaft is directly fixedly connected with an output shaft of a motor, and then the impeller is driven; due to the effect of the centrifugal force, liquid is pumped in from the water pumping pipe and then is conveyed out for filling; and thedriving shaft is sleeved with an adjusting spring. According to the automatic liquid filling centrifugal pump, by adding fan blades, a driven shaft and the adjusting spring, when the pump body just starts to work, the driving shaft and the driven shaft can be fixed, the fan blades are driven to rotate, the pump body is fast filled with the liquid due to the negative pressure generated by the fanblades, work procedures are simplified, and the labor amount is reduced.

Description

technical field [0001] The invention belongs to the field of centrifugal pumps, in particular to an automatic liquid filling centrifugal pump. Background technique [0002] Centrifugal pumps work by rotating the impeller to cause the water to move centrifugally. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pump casing. The pressure water pipeline flowing into the water pump. [0003] When the centrifugal pump is used to fill milk, etc., when the centrifugal pump starts to work, the filled dairy products tend to have air inside, and during transportation, the dairy products are prone to foam, which affects the taste of the dairy products. The above-mentioned problems of the pump require workers to fill the centrifugal pump ...

Problems solved by technology

[0003] When the centrifugal pump is used to fill milk, etc., when the centrifugal pump starts to work, the filled dairy products tend to have air inside, and during transportation, the dairy products are prone to foam, which affects the taste of the dairy products. The above-mentioned problems of the pump require workers to fill the centrifugal pump with liquid before carrying out the filling process, which not only complicates the process, but also increases the amount of labor. In view of this, the present invention provides an automatic liquid filling centrifugal pump, which has the following benefits Effect:
