Embodiment 1

[0042] like figure 1 , Extrusion type eccentric rotor water pump is composed of rotor 7, side wall 5, front cover 1 and rear cover 13, input shaft 3, inner ring gear 8, fixed gear 9, spring seal 6, wear-resistant seal ring 12, It is composed of mechanical seal 4, double row angular contact bearing 10 and so on. The rotor 7 of the extruded eccentric rotor water pump cooperates with the eccentric block of the input shaft 3 through the shaft sleeve; the input end of the input shaft 3 is assembled with the end cover through the double row angular contact ball bearing and the small end cover, and the front end cover 11 is passed through The fastening bolt is fixed with the front cover 13; the other end of the input shaft 3 is assembled with the rear end cover 11 through the double row angular contact ball bearing 10 and the rear small end cover 14, and the rear end cover 2 is connected with the rear cover through the fastening bolt. Cover 1 is fixed. The reliability of the seal ...

Embodiment 2

[0052] The difference between this embodiment and implementation 1 is:

[0053] Inside the rotor there are teeth that cooperate with the fixed gear.

Abstract

The invention discloses an extrusion type eccentric rotor pump and a use method thereof. The extrusion type eccentric rotor pump comprises a pump case, wherein a cavity is formed in the pump case, and an inlet and an outlet are formed in the pump case; a triangular rotor is arranged in the cavity, and the rotor sleeves an eccentric block of an input shaft to rotate, so that a working cavity is expanded or narrowed; the rotor is in clearance fit with a crankshaft, a fixed gear is fixedly arranged in the pump case, a gear ring which is matched with the fixed gear is arranged in the middle of the rotor, and the gear ring is fixedly connected with the rotor. The extrusion type eccentric rotor pump has the beneficial effects that the number of parts is small, so that the removal is convenient, the processing accuracy is high, the operation at high speed is stable during working, and noise is small; the manufacturing procedure is simple, and the size is small in a quantity production process, so that the cost is low, and the processing is convenient; large displacement and high efficiency of the pump are guaranteed by virtue of an advanced structure; the rotor pump has the advantages of high efficiency, portability and easiness in maintenance and is widely used for urban water supply, sewage treatment, civil and building systems, agricultural water conservancy systems, power station systems and the like.

Description

technical field [0001] The invention relates to a water pump, in particular to an extrusion type eccentric rotor water pump and a using method thereof. Background technique [0002] Existing water pumps can be divided into types such as positive displacement pumps and vane pumps according to their working principles. Positive displacement pump refers to the pump that uses the change in the volume of the pump cylinder to transport liquid, mainly including: piston pump, plunger pump, diaphragm pump, gear pump, sliding vane pump, screw pump, etc. Positive displacement pumps such as reciprocating pumps have strong self-priming ability, and the theoretical flow rate has nothing to do with the working pressure, but only depends on the speed, the size of the pump cylinder and the number of actions. However, the flow rate is not uniform, the speed should not be too fast, it is not very sensitive to the degree of liquid pollution, the structure is more complicated, there are many we...
