Abstract

The invention provides an automatic injection device for lubricating liquid of an oil field centrifugal pump. The device comprises supporting seats and a protective seat, wherein driving structures are rotatably connected to the two supporting seats, and extruding structures are mounted on the driving structures; an oil injection gun is arranged on the supporting seats, and the oil injection gun is provided with a connector structure; the connector structure comprises a connector body, the protective seat and a limiting block, wherein the protective seat is arranged on the connector body in asleeve mode, and the limiting block is arranged on the connector body; the head end of the protective seat is provided with an assembly and disassembly groove, the protective seat further comprises aclamping groove, the protective seat is provided with the clamping groove, the clamping groove is matched with the limiting block, and the clamping groove and the limiting block are of a hexagonal structure; and when the clamping groove and the limiting block are in clamped connection, the protective seat and the connector body are in an axial locking state. According to the device, the problems that automatic diffusion of an oil liquid in a pump body can be achieved only through a pressure of an oil filling pump when the centrifugal pump is subjected to liquid injection, and the diffusion effect is poor.

Description

technical field [0001] The invention belongs to the technical field of liquid injection devices for centrifugal pumps, and more specifically relates to an automatic lubricating liquid injection device for centrifugal pumps in oil fields. Background technique [0002] Lubricant is a lubricating medium used to reduce the friction resistance of the friction pair and slow down its wear. Lubricants can also play a role in cooling, cleaning and preventing pollution on friction. In order to improve the lubricating performance, suitable additives can be added to some lubricants. When selecting a lubricant, it is generally necessary to consider many factors such as the movement of the friction pair, the material, the surface roughness, the working environment and working conditions, and the performance of the lubricant. In mechanical equipment, lubricants are mostly delivered to the parts that need to be lubricated through the lubrication system. [0003] For example, patent CN201...
