PURPOSE:To supply lubricant capable of establishing excellent wear-resistance to those objects requiring lubricant supply by supplying flushing oil in a circulating process circuit so as to clean residual particles in a pump and filtering them by a filter. CONSTITUTION:A pump 4 for a lubricant supply device in an oil supply system which supplies lubricant containing fine particles such as lead, copper, zinc etc. to rig etc. and a circulating process circuit including a filter 7 are formed. Flushing oil is supplied into the process circuit and residual fine particles in the pump 4 are cleaned by flushing oil and filtered by the filter 7. By this construction, lubricant capable of establishing excellent wear-resistance such as grease can be supplied to an object 13 to be supplied with lubricant regardless of length of interval between operation and standstill of the oil supply pump. |
