Multi-medium transfer pump

Abstract

The present invention provides a multi-medium conveying pump, which includes a pump casing, a stator, a rotor, and pump vanes. The pump casing includes a first pump port and a second pump port, a first outer half-shell and a second outer half-shell. The stator includes a soft magnetic core group, a pump inner casing, and a coil group, wherein the pump blades are fixed on the inner circumference of the rotor, and first sealing rings and bearings are installed at both ends of the rotor, and the rotor passes through the The first sealing ring and the bearing are installed in the pump inner casing, the soft magnetic core group is arranged on the outer periphery of the pump inner casing, and the coil group is installed on the outer periphery of the soft magnetic core group. The present invention significantly improves the overall sealing performance of the delivery pump, achieves the purpose of leak-proof and explosion-proof, and makes the medium that can be transported more extensive, and has extremely high safety even when transporting dangerous gas or liquid medium.

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.
