Oil well pump

The invention relates to the technical field of oil pumps, in particular to an oil well pump which comprises a pump shell, a dust cover, a motor, a power line, a sealing cover, an oil stirring piece and an oil outlet. The oil pumping device can solve the following problems in the process of pumping oil into an automobile oil tank in the prior art: a gap between the output end of the motor and the motor protection shell is easy to cause oil infiltration and short circuit of the motor, the service life is influenced, and safety accidents are easy to cause; the annular cavity is formed between the inlet and the oil outlet of the pump body, suction force generated by rotation of the impeller is easily dispersed by the annular cavity, and therefore the situation that large suction force is generated in the oil suction process, and then the oil pumping efficiency is affected is avoided. The annular cavity between the pump shell and the sealing cover can be divided into a plurality of oil pumping channels for reduci
