Abstract

The invention discloses a pneumatic magnetic pump and belongs to the technical field of magnetic driving and pneumatics. A conveying impeller shaft is positioned between a left pump body and a shielding sleeve; a conveying component is sleeved on the conveying impeller shaft; a driving impeller shaft is positioned between the shielding sleeve and a right pump body and is connected with a driving component through a deep groove ball bearing; the driving component is formed by sequentially connecting an outer magnetic ring, a driving impeller left baffle, a driving impeller framework, a driving vane and a driving impeller right baffle; the conveying component is formed by sequentially connecting a conveying impeller left baffle, a conveying vane, a conveying impeller framework, an inner magnetic ring and a conveying impeller right baffle; and the left pump body, the shielding sleeve and the right pump body are connected through bolts, and are sealed by O-shaped rubber sealing rings, with high tightness. The pneumatic magnetic pump has superior performance to a pneumatic diaphragm pump, has the significant advantages of no leakage, continuous and uniform liquid conveying, energy conservation, environment friendliness, safety, reliability, convenience for use and the like, and is wide in application.

Description

technical field [0001] The invention belongs to the field of magnetic drive and pneumatic technology, and specifically relates to a new type of pneumatic magnetic pump, which can replace the widely used pneumatic diaphragm pump in some aspects, and has the advantages of no leakage, continuous and uniform liquid delivery, energy saving, environmental protection, safety and reliability, and convenient use. And other outstanding advantages, can be widely used in painting, ceramics, environmental protection, wastewater treatment, construction, sewage, coal mines, fine chemicals and other industries. Background technique [0002] With the continuous improvement of production, life and technological level, the continuous expansion of application scope and the continuous increase of the complexity of working conditions, users have higher and higher requirements for pump performance. The design of the pump has changed from the simplest structural types to a wide variety of structure...
