Novel anticorrosive pump

Abstract

The invention discloses a novel anticorrosive pump. The novel anticorrosive pump comprises a pump shell, a support and a motor, wherein an impeller is arranged in the pump shell, and comprises a bladeand a shaft sleeve arranged at the rear end of the blade; the support comprises a body, and a front end cover and a rear end cover are arranged at the front end and the rear end of the body separately; a cavity is formed in the body, a liquid inlet hole and an oil level hole are formed in the body, and are communicated with the cavity, a plug is arranged on the liquid inlet hole, and an oil levelgauge is installed in the oil level hole; and a first shaft hole connected with the cavity is formed in the centre of the front end cover, and an installation hole connected with the cavity is formedin the centre of the rear end cover. According to the novel anticorrosive pump disclosed by the invention, a cooling liquid is added in the cavity of the support, so that long-time running in the case of idle is guaranteed; parts are free from burn and deformation, so that the service life of the water pump is greatly prolonged, and the gaps of pump element fusion and liquid leakage after the idle of anticorrosive pumps at home and abroad are filled; and in addition, the pressurization capacity of the water pump is further improved.

Description

technical field [0001] The invention is a novel corrosion-resistant pump. Background technique [0002] Corrosion-resistant pump is a pump that can adapt to various working conditions, such as: transporting acid and lye; smelting industry, etc. This kind of pump needs to achieve corrosion resistance and wear resistance at the same time, which is very important for the corrosion-resistant pump itself The structure requirements are very high. [0003] Existing corrosion-resistant pumps usually include a pump body, an impeller, a bracket sleeve and a motor. The impeller is integrally formed with a shaft sleeve. The shaft sleeve passes through the bracket sleeve to connect with the motor shaft. The bracket sleeve connects the pump body and the motor. There is an oil seal on the shaft sleeve, and the oil seal is matched at the end of the bracket sleeve adjacent to the pump body to prevent the liquid in the pump body from entering the motor. Since the pumping conditions of the co...

Problems solved by technology

When working, the motor drives the impeller to run at high speed, and the shaft sleeve rotates at high speed relative to the bracket sleeve, which generates high temperature between the shaft sleeve and the bracket sleeve. During normal operation, there is liquid in the pump body, which can cool the shaft sleeve in time to ensure durability The normal operation of the anti-corrosion pump protects the shaft sleeve and bracket sleeve at the same time; however, if the liquid is delivered and the anti-corrosion pump is in an idling state, the high temperature generated between the high-speed rotating shaft sleeve and the bracket sleeve will slowly melt the shaft The contact part of the sleeve and the bracket sleeve will cause the corrosion-resistant pump to not work normally.
