Abstract

The invention discloses a mini-sized high-speed cooling-water machine pump which comprises a pump shell, a pump head, an outer shell, a rotor and a stator. The pump head is arranged on one end face of the pump shell and forms a pump cavity with the pump shell. A ceramic central spindle is fixed in the pump cavity. The rotor is arranged on the ceramic central spindle in a rotating mode through matched utilization of a graphite bearing and a ceramic gasket. A spiral guide groove is formed between the inner wall face of the graphite bearing and the outer wall face of the ceramic central spindle. Thus, in the working process, water flows in the spiral guide groove ceaselessly so as to conduct out heat generated by high-speed friction between the ceramic central spindle and the graphite bearing and effectively prevent temperature from being high to cause abrasion of the graphite bearing. Meanwhile, flowing water can achieve a natural lubricating effect on the graphite bearing, reduce friction resistance between the ceramic central spindle and the graphite bearing, and greatly improve service life of the graphite bearing, thereby improving overall service life of the water pump.
