Abstract

The invention provides an automatic lubricating fluid injection device for a centrifugal pump in an oil field, which includes a support base and a protection base. A drive structure is rotatably connected to the two support bases, and an extrusion structure is installed on the drive structure; an oil gun is installed on the support base. , and the grease gun is equipped with a connector structure; the connector structure includes a connector body, a protective seat and a limit block, the protective seat is sleeved on the connector body, and a limit block is set on the connector body; the head end of the protective seat is opened There is a disassembly slot, and the protective seat also includes a snap-in slot. There is a snap-in slot on the protective seat, and the snap-in slot matches the limit block, and both the snap-in slot and the limit block are hexagonal structures; when the clip The protective seat and the main body of the connecting head are in an axially locked state when the connecting groove is engaged with the limit block. The invention solves the problem that the oil liquid can only be automatically diffused in the pump body by the pressure of the oil injection pump when injecting liquid into the centrifugal pump, 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...
