Problems solved by technology

[0003] When the existing diaphragm pump converts the rotational kinetic energy of the power source into the kinetic energy of the back and forth movement of the pull rod, the crank slider structure is often used, but there is an inflection point in the crank slider structure. When the crank slider structure is at the inflection point, the kinetic energy of the slider is the smallest and Close to zero, causing the power of the diaphragm pump to drop sharply

Abstract

The invention discloses a diaphragm pump driven by a non-circular gear, which belongs to the technical field of pumps and solves the problems of leakage in conventional pumps and inflection point effects in existing diaphragm pumps using the crank slider structure by utilizing the structural characteristics of the diaphragm pump without dynamic sealing , can transport all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. In volatile and corrosive media, it will not cause environmental pollution and endanger personal safety. The use of non-circular gear fit eliminates the inflection point effect of the crank slider structure. The diaphragm has no rotating parts and has good passing performance, allowing the passage of particles with a maximum diameter of 10mm. And the liquid to be transported has no shear flow, the parts of the diaphragm pump itself wear less, and the damage to the transported material is small, and it can transport sludge and living organisms such as small fish fry.

Description

technical field [0001] The invention belongs to the technical field of pumps, and relates to a displacement pump, in particular to a diaphragm pump driven by a non-circular gear. Background technique [0002] Existing ordinary water pumps mostly use propellers to drive liquid or use atmospheric pressure. Ordinary water pumps must have dynamic seals, and the sealing types include packing seals and mechanical seals. Both seals inevitably have leakage, but the leakage of packing seal is larger, and the leakage of mechanical seal is smaller. However, the diaphragm pump is a new type of conveying machine, which can convey the medium completely without leakage, from the medium entering the pump inlet to the outlet being discharged from the pump. The structural design of the pump has no dynamic seal, and the medium and the atmosphere are separated by a diaphragm. [0003] When the existing diaphragm pump converts the rotational kinetic energy of the power source into the kinetic e...
