Embodiment Construction
[0031] In order to clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation modes and in conjunction with the accompanying drawings.
[0032] Such as Figure 1-6As shown, an anti-corrosion and explosion-proof vortex type hydrogen circulating pump includes a connected motor housing 1, impeller housing 2 and bearing housing 3, and a motor cavity is formed between the motor housing 1 and the impeller housing 2, and the motor cavity It is equipped with a potting stator 4, an anti-corrosion rotor 5 and a motor shaft 6. The two ends of the motor shaft 6 are supported by the bearings 7 installed on the motor housing 1 and the bearing seat 3. The motor shaft 6 and the impeller There is a gap fit between the shells 2, and the gap between the motor shaft and the impeller shell is used to maintain the pressure balance between the motor cavity and the booster cavity; a booster cavity is formed betwe...
