Title:
CONTINUOUS FEEDING PRECISE MICRO-LUBRICATING PUMP WHICH SUPPORTS DIFFERENT LUBRICATION WORKING CONDITIONS
Document Type and Number:
WIPO Patent Application WO/2019/075960
Kind Code:
A1
Abstract:
A continuous feeding precise micro-lubricating pump which supports different lubrication working conditions, comprising a pump system (1), a gas source treatment device (3), a driving system (5), an oil cup (8), a water pump (9), a two-position three-way solenoid valve (10), a water tank (11) and an emulsifying liquid storage box (12). The gas source treatment device is connected to the pump system by means of a bidirectional joint (2); the oil cup is connected to the pump system by means of an oil cup joint (1-12); the water pump is mounted in a driving box body (5-1) of the driving system and is connected to the pump system by means of a hose; the water tank and the emulsifying liquid storage box are connected to the two-position three-way solenoid valve, and the two-position three-way solenoid valve is connected to the driving system; and the driving system and the water pump are driven by a stepping motor I (5-8) and a stepping motor II (9-13) respectively. By being driven by the stepping motors, the described pump achieves functions such as: intelligent switching between various lubrication working conditions; intelligent adjustment of oil, water and gas flow mixing ratio and flow rate; and precise and continuous feeding of a lubricant to a processing region, so that the cooling and lubricating effect in the processing region is increased, the processing surface quality of a workpiece is enhanced, and equipment support is provided for intelligent feeding of micro-lubricating oil.
