Drawings
FIG. 1 is a schematic structural view of a flexible seawater pump for a marine engine according to the present invention;
fig. 2 is a schematic structural diagram between the impeller and the crescent scraper of the flexible sea water pump for the marine engine of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following drawings and detailed description:
referring to fig. 1 and 2, the present invention provides a flexible seawater pump for marine engine, which comprises a pump base 1 and a pump body 2, a rotating shaft 3 is arranged in the pump seat 1, one end of the rotating shaft 3 is connected with a gear 4, the other end is connected with an impeller 6 arranged in an impeller chamber 5 of the pump body 2, the pump body 2 is provided with a water inlet 7 and a water outlet 8, the water inlet 7 and the water outlet 8 are respectively communicated with the impeller chamber 5, a crescent scraper blade 9 is arranged in the impeller chamber 5, the impeller 6 is made of rubber and comprises a wheel body 10 and a plurality of blades 11 which are uniformly distributed on the periphery of the wheel body 10, the distance between the center of the wheel body 10 and the crescent-shaped scraper 9 is smaller than the outer diameter of the blade 11, therefore, when the blade 11 rotates to pass through the position of the crescent scraper 9, the blade 11 is bent and deformed, and the outer end of the blade 11 is tightly attached to the inner wall of the crescent scraper 9.
The outer end of the blade 11 is provided with a round raised head 12, and a neck 13 is formed between the round raised head 12 and the blade 11. The neck 13 makes the circular nose 12 more elastic with respect to the blade 11 and thus more capable of engaging with the crescent-shaped scraper 9.
A first bearing 14 and a second bearing 15 are axially sleeved on the rotating shaft 3, and a bushing 16 is arranged between the first bearing 14 and the second bearing 15; an oil seal 17 is arranged on the outer side of the rotating shaft 3, which is positioned at the first bearing 14, the pump base 1 and the pump body 2 are fixedly connected in a sealing manner, and a mechanical water seal 18 is arranged on the rotating shaft 3, which is positioned at the pump body 2.
The first bearing 14 and the second bearing 15 are both deep groove ball bearings.
A plurality of scraping teeth are arranged in the water inlet.
The utility model discloses flexible sea water pump, at the during operation, through outside power drive gear 4, thereby it is rotatory to drive pivot 3, drive 6 high-speed rotations of impeller then, at this in-process, impeller 6's blade and crescent scraper blade 9 take place the contact, receive blockking of crescent scraper blade 9, blade 11 is bent, thereby just can pass through crescent scraper blade 9 smoothly, because blade 11 is being bent the back, have the elastic potential energy of outside bullet division, and thus, crescent scraper blade 9's inner wall can be hugged closely all the time to blade 11's circular plush head 12, and thus, when impeller 6 is rotatory, reduce the clearance between impeller 6 and the impeller chamber 5 greatly, thereby improve the pressure boost effect greatly.
During operation, friction force between the blade 11 and the crescent scraper 9 always exists, in order to prolong the service life of the impeller 6, the circular raised head 12 is arranged at the end of the blade 11, the contact area between the circular raised head 12 and the crescent scraper 9 is smaller, the sealing performance is guaranteed, and meanwhile, the friction force can be reduced, so that the service life is prolonged.
The flexible sea water pump of the marine engine provided by the embodiment of the present invention is described in detail above, and the principle and the embodiment of the present invention are explained by applying a specific example, and the description of the above embodiment is only used to help understanding the technical solution disclosed by the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
