Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

The present invention discloses an oil transfer pump, referring to fig. 2 to 6, comprising: oil storage barrel 2, oil outlet pipe 3, filter 4 and pump body 5. Each component will be described separately below.

The filter 4 comprises a casing 41 and a base 42, wherein an annular filter cavity is formed in the casing 41, a filter core 44 is arranged in the filter cavity, and an inlet 411 and an outlet 412 which are communicated with the filter cavity are formed on the casing 41; an oil outlet of the pump body 5 is communicated with the inlet 411; the oil outlet pipe 3 is communicated with the outlet 412; the filter 4 and the pump body 5 are sleeved in the oil storage barrel 2.

The flange plate 1 is fixedly arranged above the oil storage barrel 2, the flange plate 1 is provided with an oil nozzle, and the oil nozzle is communicated with the oil outlet pipe 3. In some of the two types, the flange 1 can directly serve as a top cover of the oil storage barrel 2, and the flange 1 and the oil storage barrel 2 can be detachably designed for facilitating the installation, the disassembly and the replacement of the filter 4 and the pump body 5.
