Fluorine-plastic-lined self-priming pump cleaning method

Abstract

The invention relates to the technical field of pump valve preparation, in particular to a fluorine-plastic-lined self-priming pump cleaning method. The fluorine-plastic-lined self-priming pump cleaning method includes the following steps of arranging a water tank which is communicated with a pump valve, conducting high-pressure water washing, hot water softening, broken stone impact, acid liquorwashing and alkali liquor treatment, and then washing with clear water again. The fluorine-plastic-lined self-priming pump cleaning method has the beneficial effects that the cleaning technical process is simple and convenient, cleaning effect is remarkable, stains on fluorine plastic lining in a pump body can be thoroughly cleaned without detaching the pump body, cleaning efficiency is high, cleaning process rapid and safe, cleaning cost is low and therefore the fluorine-plastic-lined self-priming pump cleaning method is suitable for cleaning and processing various pump valves.

Description

technical field [0001] The invention relates to the technical field of pump and valve preparation, in particular to a cleaning method for a fluorine-lined self-priming pump. Background technique [0002] The working principle of the self-priming pump is to fill the pump casing with water before starting the pump. After starting, the impeller rotates at high speed to make the water in the impeller channel flow to the volute. The air in the tube enters the pump and travels through the impeller channel to the outer edge. The self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline. Just ensure that there is a quantitative suction liquid stored in the pump body before work.

Problems solved by technology

There is no need to install a bottom valve in the pipeline. Just ensure that there is a quantitative suction liquid stored in the pump body before work. Different liquids can use self-priming pumps of different materials. With the continuous improvement of technology, self-priming pumps are also used in various fields. Diverse, in some chemical companies, because a large amount of acid and alkali and highly corrosive liquids need to be transported, the traditional self-priming pump will have corrosion and aging problems when used, and the concentration of these problems will lead to self-priming The pump is aging and damaged

[0003] Fluorine-lined self-priming pumps have solved the corrosion problem of the above-mentioned self-priming pumps in the field of pump valves at the present stage. The process is made of metal casing tightly lined with fluoroplastics. The main flow-passing parts, impeller and pump cover, are made of metal inserts and outsourced with fluoroplastics at high temperature. The application of this method fully solves the aging problem of self-priming pumps. , but there will still be some disadvantages in actual use

[0004] Fluoroplastics are generally plastic materials. In practical applications, when they are used in some specific acid-base and sewage treatment fields, a large amount of dirt and oil will be formed inside. If they are not treated in time, they will damage the pump. The space of the cavity in the body is occupied to a certain extent, which affects the actual working efficiency of the pump body. The traditional cleaning method is to disassemble the pump body and then perform corresponding cleaning. This cleaning method is not only inefficient, but also the cleaning effect is not obvious.
