Diaphragm water pump

Abstract

The invention belongs to the technical field of diaphragm water pumps, in particular to a diaphragm water pump. The diaphragm water pump comprises a pump body and a moving mechanism. Compression boxesare fixedly connected to the left and right end surfaces of the moving mechanism, and the compression boxes are designed in cone shapes; air slots are formed in the inner wall of the moving mechanismand communicate to high pressure gas; a first gas spray holes which are uniformly arranged are formed in the inner wall of the moving mechanism on the left side of the air holes, and the first gas spray holes communicate to the compression box on the left side; second gas spray holes which are uniformly arranged are formed in the right side of the air holes, and the second gas spray holes communicate to the compression box on the right side. The diaphragm water pump is primarily used for solving the problem that the service range of the water pump is limited as the working cost is improved because it is further need to replace water pump with diaphragms of different materials when extracting other types of liquids as the diaphragm in the diaphragm water pump in the prior art is made froma special material and each diaphragm is only suitable for one liquid.

Description

technical field [0001] The invention belongs to the technical field of diaphragm water pumps, in particular to a diaphragm water pump. Background technique [0002] The diaphragm pump is actually an embolism pump, which uses a membrane to separate the infused liquid from the live column and the pump cylinder, thereby protecting the live column and the pump cylinder. The parts on the left side of the diaphragm that are in contact with the liquid are made of corrosion-resistant materials or coated with a layer of corrosion-resistant substances. The right side of the diaphragm is filled with water or oil. The flow characteristics of the diaphragm pump refer to the relative flow and displacement of the medium flowing through the valve (the relative flow of the valve) The relationship between the ideal flow characteristics mainly includes straight line, equal percentage (logarithmic), parabolic and quick opening. The commonly used ideal flow characteristics are linear, equal per...

AI Technical Summary

Problems solved by technology

[0003] The diaphragm in the diaphragm water pump in the prior art is made of specific materials, and each diaphragm is only suitable for one type of liquid. When pumping other types of liquid, it is necessary to replace the pump with a diaphragm of different materials, which will increase the working cost. The scope of use of the water pump is limited. When a matching water pump cannot be found, it is necessary to purchase a new water pump or replace the diaphragm, which increases the problem of work cost and labor intensity

[0004] There are also some schemes about diaphragm water pumps in the prior art, such as patent No. 201710645862.3, the patent name is a patent for a diaphragm pump. The diaphragm water pump made by various mechanisms in this technical scheme has a certain degree of water tightness, which can eliminate or reduce the The effect of vibration, but the sealing of the diaphragm cannot be guaranteed, and at the same time, it is more troublesome to replace the diaphragm
