AI Technical Summary
Existing grease plunger lubrication pumps are prone to air mixing during the oil suction process, which prevents sufficient pressure from being generated, affecting the lubrication and maintenance of the equipment bearings and thus shortening the equipment's lifespan.
A device for improving the grease plunger lubrication pump was designed. By installing a system pressure relief and drain copper pipe in the oil suction hole, pressure relief oil is introduced into the oil injection hole to expel air, ensuring that the grease can be smoothly sucked in and output with high pressure.
This ensures stable output from the grease plunger pump, guarantees lubrication and maintenance of the equipment bearings, and extends the service life of the equipment.

[0002] The slab continuous casting machine sector roller bearing lubrication is supplied with butter grease to the bearing by a double-line type centralized lubrication system, mainly comprises a grease supplement pump, a lubrication pump, a reversing valve and two oil supply pipes switching pressure regulating valves (when the oil pump output pressure reaches the set value 20MPa, the valve core is lifted to work the reversing valve, the oil supply pipe is switched from the first pipeline to the second pipeline, the first oil supply pipe is depressurized and oil is discharged (the pressure is from 20MPa to zero), and the lubricating grease output by the lubrication pump is alternately delivered to the two oil supply pipes through the reversing valve and then delivered to the double-line distributor for quantitative distribution and sent to each lubrication point (the roller bearing seat), however, since the butter has high viscosity and poor flowability, air is sucked in when the oil in the oil tank is supplemented to the plunger lubrication pump by the grease supplement pump, the air is sucked into the plunger pump oil suction port, the air has high compressibility, cannot form 20Mpa pressure under small compression ratio, and the compressed air expands the whole cavity when the main piston retreats, so that the main oil cavity cannot form a vacuum to suck oil, the plunger pump cannot suck in air to output pressure oil, and therefore the lubrication maintenance of the equipment bearing cannot be guaranteed, and the equipment service life is affected.
