The sliding sleeve 50 is internally provided with an oil storage channel 51, and the sliding sleeve 50 is provided with an oil inlet port 52, and the oil storage channel 51 is in communication with the oil inlet channel 12 through the oil inlet port 52. The oil outlet channel 13 is in communication with the one-way valve 60. The power supply 20 is electrically connected with the driving device 30, the output end of the driving device 30 is connected with the plunger 40, the driving device 30 drives the plunger 40 to slide left and right in the oil storage channel 51, and when the driving device 30 drives the plunger 40 to move rightward beyond the oil inlet port 52, the oil in the oil storage channel 51 is pressed towards the one-way valve 60, so that the oil pushes open the one-way valve 60 and flows into the oil outlet channel 13.
[0026] The single point lubrication pump 100 can be independently mounted at a specific position requiring oil lubrication. Since the power supply 20 is internally arranged to supply power to the driving device 30, the pump can normally output oil in the absence of power and gas, thereby ensuring normal oil supply to the position requiring lubrication. This can simplify the lubrication system and avoid the situation of insufficient lubricating oil supply caused by pipeline damage and pressure relief.
[0027] Specifically, after the driving device 30 drives the plunger 40 to slide rightward and beyond the oil inlet port 52, the plunger 40 pushes the oil to move rightward, so that the pressure in the oil storage channel 51 increases, the oil pushes open the one-way valve 60, and the oil flows into the oil outlet channel 13, and the oil flows into the lubricating position. At this time, the state is as shown in Figure 7 .
