Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a sump oil pump with a machine seal protection structure comprises a fixed platform 1 and a pipeline 6, the pump body 15, fixedly connected with pneumatic cylinder 4 on the fixed station 1, the flexible end fixedly connected with movable plate 11 of pneumatic cylinder 4, the cover is equipped with sliding sleeve 18 on the movable plate 11, sliding sleeve 18 one end has fixed block 2 through connecting rod 3 swing joint, connecting rod 3 one end is articulated with sliding sleeve 18, the connecting rod 3 other end is articulated with fixed block 2, the sliding sleeve 18 other end has briquetting 5 through two 10 swing joints of connecting rod, briquetting 5 runs through fixed block 2, two 10 one ends of connecting rod are articulated with sliding sleeve 18, the two 10 other ends of connecting rod are articulated with briquetting 5, 5 tip fixedly connected with connectors 13 of briquetting, be equipped with stop collar 7 on the connector 13, be equipped with support 12 on the fixed station 1, it has rotor plate 17 to articulate on the support 12, be equipped with stopper 8 and filter screen 14 on the rotor plate 17,
