Embodiment 1

[0042] Such as figure 1 , Extrusion type eccentric rotor water pump is composed of rotor 7, side wall 5, front cover 13 and rear cover 1, 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 front end cover through the double row angular contact ball bearing and the front small end cover, and the front end cover 11 It is fixed with the front cover 13 by fastening bolts; the other end of the input shaft 3 is assembled with the rear end cover 2 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 end cover by fastening bolts. Cover 1 is fixed. The reliability of the seal makes...

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 extruded eccentric rotor water pump and a using method thereof, comprising: a pump casing, the pump casing is provided with a cavity, and the pump casing is provided with an inlet and an outlet; a triangular rotor is arranged in the cavity, and the rotor is sleeved on an input shaft. The eccentric block rotates to realize the increase or decrease of the working chamber; the rotor and the crankshaft are in clearance fit, the fixed gear is fixed in the pump casing, and the ring gear matching the fixed gear is installed in the middle of the rotor, and the ring gear is fixedly connected to the rotor . The beneficial effects of the present invention are: due to the small number of parts, convenient disassembly and high processing precision, the high-speed operation is stable and the noise is small; in the mass production process, the cost is low due to the simple processing procedure and small volume. It is easy to process; the advanced structure ensures the large displacement and high efficiency of the water pump; the rotor water pump in the present invention is high in efficiency, relatively light and easy to maintain, and is widely used in urban water supply, sewage treatment, civil engineering and construction systems, and agricultural water conservancy systems , Power station system, etc.

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...
