Multi-medium conveying pump

Abstract

The invention provides a multi-medium conveying pump. The multi-medium conveying pump comprises a pump shell, a stator, a rotor and a pump blade, wherein the pump shell comprises a first pump port, asecond pump port, a first outer half shell and a second outer half shell; and the stator comprises a soft magnet core, a pump inner shell and a coil assembly, wherein the pump blade is fixed on the inner periphery of the rotor, a first sealing ring and a bearing are installed at the two ends of the rotor, the rotor is installed in the pump inner shell through the first sealing ring and the bearing, the soft magnet core is arranged on the periphery of the pump inner shell, and the coil assembly is installed on the periphery of the soft magnet core. According to the multi-medium conveying pump,the overall sealing performance of the conveying pump is remarkably improved, the purposes of leakage prevention and explosion prevention are achieved, the conveyed medium can be wider, and the high safety is achieved as well even if dangerous gas or liquid medium is conveyed.

Description

technical field [0001] The invention belongs to the technical field of conveying pumps, and more specifically relates to a multi-media conveying pump capable of conveying different media. Background technique [0002] As an important equipment for transporting fluid or pressurization, the pump is mainly used to transport water, oil, acid and lye, etc., and can also transport gas, liquid-gas mixture and liquid containing suspended solids. The existing conveying pump is mainly composed of three parts: motor, pump blade and casing. However, since the motor shaft is directly or indirectly connected to the pump blade, the rotation of the motor makes the shaft unable to be absolutely sealed, and the wire part needs to be protected from contact with the conveying medium. Therefore, the existing delivery pumps can generally transport leakable safe media, but for some special media, it is impossible to complete safe transfer, especially dangerous gas media, liquid media with a certai...

Problems solved by technology

In the prior art, the hydrogen fuel cell system is equipped with an electric diaphragm pump. However, due to reasons such as small flow rate, large and heavy pump volume, high cost, and difficulty in ensuring sealing, most manufacturers have to cancel this accessory, resulting in hydrogen pulses. Reduced exhaust cycle, increased hydrogen emissions, insufficient hydrogen reaction, and reduced efficiency of fuel cell system power generation, etc.
