Abstract
The utility model relates to a packingless and leakingless pump which is self-controlled and self-sucked. The packingless and leakingless pump comprises a motor, a pump body, a pump shaft, an electromagnetic valve and a self-sucking valve. The packingless and leakingless pump is characterized in that the pump shaft in the pump body is connected with the main shaft of the motor; the lower part of the pump shaft is provided with an impeller, and the upper part is provided with an auxiliary impeller which is provided with a sealing filling piece; the right side of the pump body is provided with the electromagnetic valve, and the left side is provided with the self-sucking valve. The packingless and leakingless pump adopts the motor which drives the pump shaft to rotate at a high speed, so the pump body forms an interlinked multidimensional centrifugal seal to overcome the defects of running, emitting, dripping and leaking of the pump body. The utility model has the advantages of heat resistance, pressure resistance, abrasion resistance and long service life. Because the self-sucking pump and the electromagnetic valve are arranged, the packingless and leakingless pump has reliable self-sucking ability and realizes once conduction and always self-sucking function. The utility model has reasonable design, simple structure, reliable operation, convenient disassembly and easy installation.
Description
Technical field
The utility model relates to a kind of pump, exactly is that a kind of nothing sealing does not have the automatic control of leakage self-priming pump.
Technical background
Used traditional water pump is provided with packing seal, packing_seal, mechanical seal, therefore very easily produces " run, drip, leak ", and easy to wear in the running, thus working life is short.
The utility model content
The purpose of this utility model is at existing problem, providing a kind of to people does not only have " run, drip, leak " defective, and has heatproof, withstand voltage, wear-resisting, long service life, simultaneously reliable, convenient disassembly, the nothing sealing that is easy to advantages such as installing does not have the automatic control of leakage self-priming pump.
The utility model comprises motor, the pump housing, impeller, sub-propeller, pump shaft, solenoid valve and self-priming valve, it is characterized in that: the pump shaft in the pump housing connects with electric machine main shaft, impeller is equipped with in the pump shaft bottom, sub-propeller is equipped with on top, gasket seal is housed on the sub-propeller, solenoid valve is equipped with on pump housing the right, and self-priming valve is equipped with on the left side.
Described self-priming valve comprises valve body, valve pocket, and the flap that valve body lower end portion is equipped with, rubber plate, pressing plate are fixed by nut, and valve body is equipped with valve pocket outward, and the outer dress of valve pocket is by the gasket seal of bolt.
Effect of the present utility model
1, the utility model is owing to adopt driven by motor pump shaft high speed rotating to make the pump housing form a chain of formula " the multiaspect centrifugal seal, thus " run, drip, leak " defective of not only having subdued the pump housing, and have the advantage of heatproof, withstand voltage, wear-resisting, long service life.
2, the utility model is because the self-priming valve and the solenoid valve of dress, thereby self-priming performance is reliable, and realized the function of " drainage, lifelong self-priming ".
3, the utility model is reasonable in design, and is simple in structure, reliable, and convenient disassembly is easy to install.
