The oil supply and lubrication oil injectors are completely identical in structure, mainly composed of orifice nozzles, diffusion tubes, sleeves, filters, etc.

The function of the oil injector of Lianyungang Lingdong Electromechanical Equipment Co., Ltd. is to use a small amount of lubricating oil as power, suck in a large amount of oil, and supply lubricating system and main oil pump with oil at a certain pressure.

The oil injector is composed of a nozzle, a filter screen, an expansion pipe, and an inlet pipe. In addition to supplying the inlet oil of the centrifugal main oil pump, it also supplies lubricating oil system and sealing oil system oil.

The working status of the oil injector and main oil pump, the analysis of the reasons for the drop in the inlet oil pressure test of the main oil pump of a 200MW steam turbine, and the composition of the oil supply system of the 200MW steam turbine generally adopt a centrifugal main oil pump oil supply system with dual injectors.

The oil injectors produced by Lianyungang Lingdong Electromechanical Equipment Co., Ltd. generally consist of nozzle filters, expansion pipes, inlet pipes, etc., and are installed on the main oil pump.

The oil injector of Lianyungang Lingdong Electromechanical Equipment Co., Ltd. is a device used for supplying lubricating oil to internal steam turbines using an oil injector system. Its power oil comes from an independent oil pump (starting from an AC high-pressure oil pump),
