Abstract

The invention belongs to the technical field of diaphragm pumps, and particularly relates to a self-priming non-clogging diaphragm pump. According to the scheme, the pump comprises a liquid pumping pipe, a diaphragm seat and a fixed pipe which are communicated in sequence, wherein a diaphragm is fixed to the middle of the diaphragm seat; a movable plunger is arranged in the fixed pipe and can move; a driving cavity is formed in the side, close to the movable plunger, of the diaphragm in the diaphragm seat; a liquid pumping cavity is formed in the side, close to the liquid pumping pipe, of the diaphragm in the diaphragm seat; a first piston mechanism is arranged at the position, corresponding to the liquid pumping cavity, of the outer wall of the liquid pumping pipe; a second piston mechanism is arranged at the end of the outer wall of the liquid pumping pipe; and a communicating pipe is connected between the first piston mechanism and the second piston mechanism. The air pressure change driven by the diaphragm is effectively utilized to dredge the liquid inlet end, so that the liquid inlet end is effectively prevented from being clogged to affect the whole liquid pumping operation, and excessive damage to the diaphragm due to suction of the diaphragm position is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of diaphragm pumps, in particular to a self-priming non-clogging diaphragm pump. Background technique [0002] The diaphragm pump is actually an embolism pump, which separates the infused liquid from the live column and the pump cylinder by means of a thin film, thereby protecting the live column and the pump cylinder. By receiving the control signal output by the adjustment control unit, the fluid flow is changed by means of power operation. It is often used to transport relatively viscous slurry. [0003] The self-priming diaphragm pump commonly used in the prior art is provided with a diaphragm on one side of the pump liquid pipeline, and the diaphragm is reciprocated to both sides from the other side of the diaphragm through electric, pneumatic or hydraulic power, so that the pump liquid The air pressure at the position of the diaphragm changes reciprocatingly from the pipe to the diaphragm, and the liq...
