[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0014] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a novel electric grease pump includes an upper bracket 1, a lower bracket 6, an integrated pump barrel assembly 3 and a base 7, the upper bracket 1 and the integrated pump barrel assembly 3 are bolted, the upper part of the adapter base 4 is connected to the integrated pump barrel assembly 3, the lower part of the adapter base 4 is connected to the base 7, the lower bracket 6 is bolted to the base 7, the integrated pump barrel assembly 3 includes a single pump barrel 2 and a lip seal 5, the adapter base 4 is manufactured by aluminum casting technology, and the single pump barrel 2 is manufactured by centrifugal casting of acrylic material.

[0015] Grease is pumped into the integrated pump barrel assembly 3 through the oiling nozzle of the base 7 by the grease pump. As the grease is gradually squeezed in, the internal air is discharged through the gap formed by the fishing line and the pressure plate lip seal 5. When the grease completely fills the pump barrel cavity, the fishing line can be quickly pulled out to complete the sealing of the pump barrel cavity. At the same time, the grease pushes the pressure plate to gradually rise. When the bottom of the pressure plate lip seal 5 is close to the exhaust hole, the grease filling is stopped, and the maximum liquid level is reached at this time. After the grease pump is installed at the specified position of the wind turbine through the upper bracket 1 and the lower bracket 2 and connected with the distributor, pipeline, controller, etc., the motor rotates to drive the cam structure to push the pump core to discharge grease, and the key gear lubrication is completed in a timely and quantitative manner according to the established program of the controller. After the electric grease pump has been running for a period of time, when the bottom of the pressure plate lip seal 5 moves close to the low liquid level, the proximity sensor in the base 7 triggers the switch and sends a low liquid level signal alarm, notifying the maintenance personnel to add grease again.

[0016] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
