Problems solved by technology

Chinese patent application No. 96244274.7 discloses a motor water-filled vertical submersible pump. Because the motor chamber is immersed in water and the water does not flow, there are the usual shortcomings of the aforementioned wet submersible pumps.
Chinese Patent Application No. 91214552.8 discloses a high-efficiency self-priming centrifugal pump with a gas-liquid separation chamber that can be switched on and off. The disclosed technical structure is complex, the volume is large, and it cannot be integrated with the pump. Off, very inconvenient to use

Embodiment Construction

[0014] The structure of the amphibious high-efficiency self-priming centrifugal pump is that the motor stator 15 and the rotor 16 are installed in the motor casing 9, the motor shaft is supported by the bearing 11, and the two ends of the motor shaft are respectively equipped with an impeller gap adjustment device 5 and an axial adjuster 12. The motor casing 9 is a double-layer hollow casing. The hollow layer of the motor casing 9 is a water channel 14. The motor casing 9 has a water inlet pipe 13 and communicates with the water channel 14. The other end of the motor casing 9 is connected to the impeller seat plate 7 through the motor end cover 8. The impeller 4 is contained on the motor shaft, and the impeller 4 is covered in the inner cavity of the impeller cover 6 and the impeller seat plate 7, and the impeller 4 has an impeller water inlet end cavity 23 and an impeller inner cavity 24 that are connected. The impeller 4 is equipped with three-stage blades, the first-stage bl...

Abstract

The present invention relates to an amphibious high-effective self-sucking centrifugal pump, belonging to the field of centrifugal pump technology. The motor outer shell is made into the form of hollow thin shell, on the volute casing of blade wheel is cut an air self-purging channel, and on the volute casing of blade wheel a gas-water separator is mounted. Said blade wheel possesses three-stage blade, and in the gas-water separator an automatic valve is mounted, said automatic valve has a valve cover with plunger type valve core and a valve seat with conical surface. Said invention also provides the working principle of the invented amphibious high-effective self-sucking centrifugal pump and its operation method.

Description

technical field [0001] The invention relates to centrifugal pump technology, in particular to an amphibious high-efficiency self-priming centrifugal pump. Background technique [0002] At present, the traditional submersible pumps are divided into three types: wet type, dry type and oil immersed type. For wet submersible pumps, in order to prevent leakage, the motor must be wound with plastic sealed wires. Although there is water in the machine chamber, because the water does not flow, the temperature rises quickly and the heat dissipation is poor. , not only the winding power becomes smaller, the magnetic field strength also becomes smaller, and the power consumption is high. For dry submersible pumps, the motor is filled with air. Although it is immersed in water, the heat dissipation conditions are poor because the water does not flow. Because the air in the motor body expands due to heating when the motor is working, some air escapes, so that water will flow to the pump...
