Automatic control pneumatic diaphragm pump

Abstract

The invention discloses an automatic control pneumatic diaphragm pump, which comprises a pump shell, wherein a feeding pipeline, a discharge pipeline, a left flow channel and a right flow channel arearranged on the inner wall of the bottom of the pump shell; both ends of the left flow channel and right flow channel are communicated with the feeding pipeline and the discharge pipeline; a valve seat is respectively arranged at both ends of the left flow channel and the right flow channel, a valve ball is arranged at the inner wall of the bottom of the valve seat, a compression chamber, a control mechanism and an exhaust chamber are arranged on the inner wall of the bottom of the pump shell, between the opposite sides of the left flow channel and right flow channel, and the control mechanismis positioned between the compression chamber and the exhaust chamber. According to the invention, a magnetic rod is driven by a connecting rod and a moving rod, the moving rod moves to be connectedwith a Hall sensor signal, an exhaust pipe is connected on one side, prior moving rod linkage is replaced with the electrical signal, conducting fins are arranged in a whole inner cavity, a silencer is changed, a vibration ball cancels the noise and vibration generated when the compression gas is discharged, and abnormal sound is not generated when the gas is discharged.

Description

technical field [0001] The invention relates to the technical field of pneumatic diaphragm pumps, in particular to an automatically controlled pneumatic diaphragm pump. Background technique [0002] Pneumatic diaphragm pump is a new type of pneumatic double-diaphragm pump, which has the advantages of long service life and no pause. It can not only pump flowing liquid, but also transport some difficult-to-flow media. Many advantages of conveying machinery such as pumps, mud pumps and impurity pumps. Pneumatic diaphragm pumps use compressed air as the power source. For various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids, All can be exhausted, especially suitable for flammable and explosive fields. After searching, the Chinese patent publication number is CN205977625U, which discloses a pneumatic diaphragm pump for liquid transportation, including a pneumatic diaphragm pump, a first hard tube, a liquid inlet tube, a ...

AI Technical Summary

Problems solved by technology

[0003] The pneumatic diaphragm pump in the above-mentioned patents has the following disadvantages: the direction of the pneumatic diaphragm pump is controlled by the linkage plug on the movable rod, and there is a delay in changing the direction and entering and exiting the air, which will cause uneven stress on the diaphragm for a long time and rupture. The compression chamber and exhaust chamber on both sides, the gas in the compression chamber is compressed to generate heat, and the release of the exhaust chamber will absorb heat, resulting in uneven heat in the diaphragm pump as a whole, affecting the material flow in the flow channel, and the effect of the traditional muffler is poor , not conducive to the air-operated diaphragm pump to eliminate vibration and noise from the inside
