Abstract

The invention provides a non-symmetrical type diaphragm pump. The non-symmetrical type diaphragm pump comprises a power assembly, a compressing portion and a conveying portion connected in sequence; the power assembly comprises a motor and a rotor; the rotor is provided with an eccentric hole; the compressing portion comprises a steel shaft, a diaphragm driver and a diaphragm; a driving connectionhole is formed in the diaphragm driver; one end of the steel shaft is inserted into the connection hole; the other end of the steel shaft is inserted into the eccentric hole of the rotor; the diaphragm driver is provided with at least two diaphragm connection holes, and the distances between the at least two diaphragm connection holes and the driving connection hole are different; the diaphragm is provided with at least two air bags; and the conveying portion is arranged to input or discharge gas and / or liquid. The non-symmetrical type diaphragm pump is simple in structure, can achieve the purpose of mixing liquid and / or gas in various proportions, is good in mixing effect and wide in application range and has great market popularization value.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to an asymmetric diaphragm pump. Background technique [0002] At present, as a new type of fluid conveying machinery, the diaphragm pump is being gradually promoted and applied in China. Existing diaphragm pumps are mostly used to transport a single gas or liquid, and adopt a symmetrical structure to realize the mixing of gas and liquid through the communication between the diaphragm and the atmosphere. However, due to the limitations of its driving structure and diaphragm structure, the degree of freedom in setting the proportion of liquid and / or gas is low, and the mixing effect is poor, especially because it cannot mix a higher proportion of liquid and / or gas, which makes the diaphragm pump There are great limitations in practical applications. [0003] Chinese patent CN 02235834.X discloses an improved micro-pump gas diversion structure, which is composed of a motor a...
