Technical Field

The application relates to the technical field of valve grease injection, in particular to a grease injection machine.

Background

After a device used in the conventional well site exploitation, fracturing, drilling, well cementation and flowback processes is operated for a period of time, high-pressure fluid flowing at high speed in the device can cause partial grease loss, and the device is required to be subjected to grease supplementing, so that the grease supplementing is beneficial to sealing, lubrication, sand accumulation prevention and the like of the device; at present, the fracturing operation tends to a platform with high sand ratio, large discharge capacity, high pressure, modularization and factory layout, on one hand, the large flow rate requires the drift diameter size and pressure of a wellhead fracturing valve to be larger and larger, and meanwhile, grease is accelerated to run off; on the other hand, the high sand ratio puts higher requirements on sand accumulation prevention;
