A FIXING STRUCTURE FOR LUBE OIL PUMP OF WATER INJECTION PUMP

摘要

A structure is provided to fix a lubricant pump which supplies lubricant to a bearing of a water injection pump so as to reduce nitrogen oxide from gas burned in a gas turbine. In a structure of fixing a lubricant pump(2) of a water injection pump, which includes a shaft(1) and an embedded spring(3) and supplies lubricant to the shaft and a ball bearing(4), to a low-speed shaft(5) with fixing pins(11a,11b), the fixing pins face each other to fix the lubricant pump to two opposite sides of the low-speed shaft. The fixing pins are welded to the inner walls of holes formed around the lubricant pump so that the fixing pins are prevented from being separated.
