Detailed Description

The present invention will be further described with reference to the following examples.

Example 1

As shown in fig. 1-3, a submersible pump comprises a pump shell 25, a motor 9, a motor shaft 10, a base 22, an impeller 19, a grinding fling wheel 5 and a pump head 1; the pump shell 25 is sleeved outside the motor 9 in a matching way; the pump head 1 is fixedly arranged at the left end of the pump shell 25, and the base 22 is fixedly arranged at the right end; the right end of the motor shaft 10 is fixedly provided with an impeller 19, and the left end is fixedly provided with a fling grinding wheel 5. Through getting rid of the setting of emery wheel 5, can avoid the grit to gather in pump head 1 department, reduced the trouble. Through the setting of motor shaft 10, can drive impeller 19 simultaneously and get rid of the rotation of emery wheel 5, make full use of the space, guaranteed the use in narrow and small space. The left end of the motor shaft 10 is connected with the impeller in the pump head 1 through the coupler 3, and therefore liquid can be further extracted and discharged.
