Novel sanitary self-priming pump

Abstract

The invention discloses a novel sanitary self-priming pump, which belongs to the field of light industrial machinery, and comprises a motor, a centrifugal pump and a circulating reflux pipeline. The circulating reflux pipeline is formed by a water-sealing bend pipe, a water-sealing ball, a gas-liquid separation chamber and the like; two ends of the circulating reflux pipeline communicate with a water inlet pipe and a water outlet pipe of the pump; and the circulating reflux pipeline has functions on automatically opening and closing, separating gas and liquid, and sealing water, so that a common sanitary centrifugal pump becomes the novel sanitary self-priming pump with a self-priming function. On the premise that the pump meets the requirement of a sanitary property, the defects of low efficiency and big noise of a traditional self-priming pump are overcome, the efficiency is improved by more than 20 percent, the noise is reduced by more than 12 decibel, and the novel sanitary self-priming pump has a performance feature of the centrifugal pump, can meet different working condition requirements through changing the rotation speed or changing an outer diameter of an impeller, has the functions which cannot be realized by the traditional vortex sanitary self-priming pump, and is a substitute product of the traditional self-priming pump. The novel sanitary self-priming pump provided by the invention is simple in manufacturing process, has no quick-wear part, and is reliable to use, stable in performance, high in practicability, high-efficient, energy-saving and noise-reducing.

Description

technical field [0001] The invention relates to a sanitary fluid conveying device suitable for high gas content or self-priming working conditions, in particular to a new type of sanitary self-priming pump, which belongs to the field of light industry (food, dairy, beverage, pharmaceutical, etc.) machinery. Background technique [0002] At present, the sanitary self-priming pump used in the CIP cleaning system of the food (beer, beverage, dairy products, etc.) and pharmaceutical processing industries is the traditional vortex type sanitary self-priming pump. The biggest disadvantage of the vortex type sanitary self-priming pump is low efficiency and high noise. It cannot meet the current green environmental protection requirements of energy saving, consumption reduction and noise reduction, and corresponding new high-efficiency energy-saving products are urgently needed. Contents of the invention [0003] In order to solve the above technical problems, the present inventio...
