The working principle is as follows:

the first step is as follows: through the design of spring 107 and reinforcing sleeve 3, because the front side mouth 104 is in for the front end of impeller pump, compare in the one end that motor 206 exists, because there is not control between the power, thereby the range of vibrations is bigger than the one end that motor 206 exists, consequently spring 107 has been designed to the inside of front side mouth 104, make spring 107 can absorb partly because the vibrations problem that impeller pump during operation brought, the reinforcing sleeve 3 has been set up in the outside simultaneously, carry out reinforcement processing to the outside of front side mouth 104, the influence of working vibrations to the front end of impeller pump has been alleviated to a certain extent like this, the holistic anti-seismic performance of device has been improved.

The second step is that: through the design of the blade 204, most of the blades 204 on the market are still rectangular, and the blade 204 is designed to be L-shaped, so that the blade 204 can be in contact with the L-shaped inner wall of the blade 204 in the process of entering oil from the inlet 102, and compared with the original rectangular blade 204, the contact area of the blade 204 colliding with the oil is increased, so that the blade 204 can be driven to rotate by entering the oil, especially for a blade pump completely in a running state, the oil can continuously enter and exit, and extra power can be brought to the rotation of the blade 204, so that certain power resources are saved.

The third step: through adding in the outside at blade 204 and establishing cleaning sheet 205, because the inner wall of stator 207 is in inside for a long time and oil and contacts, after a period, can leave remaining dirt on the inner wall of stator 207 always, long-term not clear up then can cause the flow of vane pump to be littleer and smaller, can influence the work efficiency of vane pump, no matter can play certain scrubbing effect to the inner wall of stator 207 in the course of the work or in the course of clearing up through cleaning sheet 205, avoided the remaining dirt of stator 207 inner wall to cause the influence to the work of vane pump, the life of device has been improved.

The fourth step: through the design of flow controller 4, set up apron 408 in the right side of entry 102, in the in-process of going out oil through entry 102, if the oil in the too big pump case 101 of flow can be followed the entry 102 mouth and erupted, so apron 408 can move to the right side, thereby drive two 406 rotations of gear, the meshing of rethread two 406 and gear 404, thereby drive the rotation of pointer 405, in the instruction process of following pointer 405, can follow observation groove 402 and read the data on scale plate 403, thereby obtain the data of flow, be convenient for observe the data of impeller pump.

The fifth step: through the design of the speed reducer 5, in the process that the cover plate 408 moves to the right due to the fact that oil is sprayed out of the inlet 102, through the linkage effect of the left connecting rod I410, the fixing rod I411 and the speed reducer 5, the cover plate 408 drives the speed reducing column II 502 to move towards the direction along the lantern ring 503 in the process of moving to the right, so that the circular plate 506 is pushed to move towards the left, then the speed reducing rod 507 is pushed to move towards the right, the end, far away from the circular plate 506, of the speed reducing rod 507 moves towards the direction close to the rotating shaft of the motor, the friction plug, far away from the circular plate 506, of the speed reducing rod 507 can reduce the rotation of the motor, the flow of an oil outlet is controlled, and.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
