Efficient centrifugal chemical pump

Abstract

The invention discloses an efficient centrifugal chemical pump which comprises an installation plate. The upper surface of the installation plate is provided with four telescopic rods. The four telescopic rods are evenly distributed on the periphery of the upper surface of the installation plate. The upper ends of the outer side faces of the telescopic rods are provided with second positioning rings, the lower ends of the outer side faces of the telescopic rods are provided with first positioning rings, damping springs are arranged between the upper surfaces of the first positioning rings andthe lower surfaces of the second positioning rings, the upper end faces of the telescopic rods are provided with a supporting plate, and rear side of the upper surface of the installation plate is provided with an air pump. According to the efficient centrifugal chemical pump, the structure is compact, installation is convenient, operation is easy, liquid chemical raw materials can be acceleratedto high-speed jet, the transportation efficiency of the chemical raw materials is improved, meanwhile, an electric pump body is cooled, the electric pump can work efficiently continuously, a movable rod and a sealing rubber block are combined so as to absorb vibration produced by the electric pump body during working, and installation and fixing of the pump are facilitated by forming an installation hole.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a high-efficiency centrifugal chemical pump. Background technique [0002] The working principle of the self-priming pump is: before the pump is started, the pump casing is filled with water (or there is water in the pump casing itself). After starting, the impeller rotates at high speed to make the water in the impeller channel flow to the volute. At this time, the inlet forms a vacuum, which makes the water inlet check door open, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel. 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, and it is only necessary to ensure that there is a quant...

Problems solved by technology

Although this type of electric pump body is effective in use, it is found during use that because the electric pump will generate a large amount of heat after working for a long time, it needs to be shut down to dissipate heat, which reduces the work efficiency; on the other hand, the existing centrifugal chemical pump works Vibration will be generated during the process, if these vibrations are not dealt with, it is very likely to cause leakage of chemical raw materials

At the same time, the jet pressure of existing chemical pumps is extremely small, which is not conducive to long-distance pipeline transportation of chemical raw materials
