Problems solved by technology

The structure is not simple enough, the damage rate is high after being immersed in water for a long time, and the service life is short. In order to prevent sundries from entering the pump, the existing water pump will install a water filter cover at the input end of the pump, but the water filter cover will be damaged after a period of use. , the round hole on the water filter cover will be blocked, which will reduce the filtration efficiency of the water filter cover, and the water flow will become smaller and affect the pumping efficiency of the water pump. Based on the above-mentioned problems, we provide a carbon-graphite bearing and Water pumps with ceramic bearings

Embodiment 1

[0032] see Figure 1-4 , in an embodiment of the present invention, a water pump based on carbon-graphite bearings and ceramic bearings includes a base plate 1, a pump casing 19 is installed on the upper end surface of the bottom plate 1, and a pump chamber 16 is provided in the middle of the pump casing 19. The pump The right side of the casing 19 is provided with an installation chamber 23, and the side of the pump casing 19 far away from the installation chamber 23 is connected with a water inlet cylinder 26 communicating with the inside of the pump chamber 16. A water filter assembly for filtering water;

[0033] The water filtering assembly includes a mounting frame 14, which is fixedly connected to the end of the water inlet cylinder 26 away from the pump casing 19, and the middle position of the mounting frame 14 is provided with a rotating sleeve 7, and the rotating sleeve 7 is rotationally connected with The rotating shaft 11 is fixedly connected with the blade 8, an...

Embodiment 2

[0042] see Figure 5-6 The difference from Embodiment 1 is that the anti-blocking assembly also includes a mounting hole block 29, and the two mounting hole blocks 29 are fixedly connected to the positions of the upper end and the lower end of the water inlet cylinder 26 respectively, and the two mounting hole blocks 29 are fixed Connected with a V-shaped brush frame 31, the V-shaped brush frame 31 is provided with bristles 30 on one side close to the water filter cover 10; the bristles arranged on the V-shaped brush frame 31 can make cleaning easier It is clean and effectively prevents sundries from clogging the water hole 9 .

[0043] The working principle of the present invention is: when the present invention is in use, the driving motor 22 drives the impeller 5 to rotate, so that the water inlet cylinder 26 and the water outlet 17 generate a pressure difference, and the water is sucked from the water hole 9 on the water filter cover 10 and passed through the water inlet. ...

Abstract

The invention discloses a water pump based on a carbon graphite bearing and a ceramic bearing. The water pump comprises a bottom plate, a pump shell is mounted on the upper end face of the bottom plate, a pump cavity is formed in the middle of the pump shell, a mounting cavity is formed at the right side of the pump shell, and a water inlet cylinder communicating with the interior of the pump cavity is connected to the side, away from the mounting cavity, of the pump shell; and a water filtering assembly used for filtering water entering the pump cavity is installed on the water inlet cylinder. An anti-blocking assembly is further arranged on the water inlet cylinder and used for preventing the water filtering assembly from being blocked. The carbon graphite bearing and the ceramic bearing are adopted as stress parts, the characteristic of a small friction coefficient is achieved, the frictional resistance moment is reduced, and the overall operation efficiency of the water pump is improved. Meanwhile, the carbon-graphite bearing and the ceramic bearing are suitable for running in a water lubrication state, grease is not needed for lubrication, grease leakage is avoided from polluting the environment, and the device is suitable for the working environment of the water pump.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a water pump based on carbon graphite bearings and ceramic bearings. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures and liquids containing suspended solids can also be transported. [0003] At present, the existing water pump inner bearing system still uses grease lubricated rolling bearings to bear the axial force and radial force. In order to prevent the bearing from being soaked in water and fail, it is necessary to install a mechanical seal at the front end of the bearing. The structure is not simple enough, the damage rate is high after being immersed in wat...
