Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1-3, a support for an oil transfer pump comprises a limiting ring 1, wherein the limiting ring 1 is of an annular structure, a mounting ring 2 is arranged on the inner side of the limiting ring 1, a plurality of side rods 3 distributed in an annular array are arranged between the mounting ring 2 and the limiting ring 1, the side rods 3 are distributed along the radial direction, one ends of the side rods 3 are fixedly connected with the limiting ring 1, the other ends of the side rods are fixedly connected with the mounting ring 2, fixing columns 4 are arranged on the inner side of the mounting ring 2, the fixing columns 4 are of cylindrical structures, the fixing columns 4 are coaxial with the mounting ring 2, and the mounting ring 2 is connected with the fixing columns 4 through mounting sleeves 5.
The scheme comprises the following working processes:
when the support is used, the fixed column 4 is fixedly connected with the oil delivery pump body 7 in a welding mode, then the whole formed by connecting the limiting ring 1, the mounting ring 2, the side rod 3, the mounting sleeve 5 and the like is fixed with the fixed column 4, the shell is used for installing the support, after the oil delivery pump body 7 and the high-pressure pump body are fixedly connected by the fastening bolts 8, the limiting ring 1 is fixed with the oil delivery pump body 7, when a certain fastening bolt 8 is loosened, the limiting ring 1 and the oil delivery pump body 7 are inevitably caused to synchronously deflect, however, the outer wall of the limiting ring 1 is attached to the outer walls of nuts of all the fastening bolts 8, the acting force exerted by the fastening bolts 8 acts on other fastening bolts 8 through the limiting ring 1, and under the limitation of the limiting ring 1, the fastening bolts 8 can keep a parallel spatial relationship, so that the probability of installation stability reduction caused by the loosening of part of the installation position of the oil delivery pump can be reduced.
