High-performance strong-corrosion-resistant self-sucking pump

Abstract

The invention discloses a high-performance strong-corrosion-resistant self-sucking pump. The self-sucking pump comprises a foundation which is fixedly connected with a pump body; the self-sucking pump is characterized in that: a trumpet-shaped suction pipe with a conical hole is arranged in the pump body; a jet flow nozzle is arranged in a pump front cover at the front end of the suction pipe, and a guide wheel and an impeller are arranged at the rear end of the suction pipe in a rotatable way; the rear end of the pump body is provided with a pump cover; the impeller is connected with a drive mechanism through a rotation shaft or in a magnetic transmission mode; the upper wall of the pump body is communicated with a pump body outlet; the jet flow nozzle is fixedly arranged in front of the front mouth of the suction pipe; the jet flow nozzle is communicated with a pressure chamber of the pump body through a channel in the pump body; and a check valve is fixedly arranged in the inlet of the pump body. Due to the creative design of a product, air and liquid separation is performed quickly, the self-sucking time is reduced obviously, the sucking travel is greatly improved, and the problem that a product cannot be conveyed under the working conditions of long sucking travel and high self-sucking frequency of the conventional corrosion-resistant self-sucking pump can be solved completely.

Description

technical field [0001] The invention relates to the field of self-priming pumps, in particular to a high-performance and strong corrosion-resistant self-priming pump. Background technique [0002] High-performance and strong corrosion-resistant self-priming pump is a new type of powerful self-priming pump that is carefully designed and manufactured by using the Venturi effect principle to perfectly combine jet flow and centrifugal self-priming pump. It integrates corrosion resistance, self-priming and conveying. Function in one, compact structure, high suction lift, short self-priming time, it is an ideal product for transporting various media such as strong acid, strong alkali and organic solvent in the new generation of chemical industry. [0003] At present, the existing corrosion-resistant self-priming pumps in China generally have defects such as small suction distance (generally within 3 meters), poor gas-liquid separation effect, and long self-priming time. When ...

Problems solved by technology

[0003] At present, the existing corrosion-resistant self-priming pumps in China generally have defects such as small suction distance (generally within 3 meters), poor gas-liquid separation effect, and long self-priming time. When using the self-priming function (that is, the pumping bucket), there are often phenomena such as difficulty in filling the liquid due to poor self-priming effect, failure of self-priming, and even damage to the pump. transported to the reactor
