Description

Technical Field

[0001] The utility model relates to the technical field of oil injectors, and in particular to a pressure-resistant sealed oil injector nozzle. Background Art

[0002] The oiler is one of the main equipment of the centrifugal oil pump oil supply system, mainly composed of a nozzle, a mixing chamber and a diffuser. The pressure is accelerated in the nozzle through the main oil pump, thereby forming a negative pressure in the mixing chamber of the nozzle. Due to the negative pressure and the entrainment of the free jet, the oil in the mixing chamber in the oil tank is continuously brought into the diffuser. The mixed oil flow is decelerated and pressurized in the diffuser, and then sent to the main oil pump or the bearing lubrication oil.

[0003] Most of the oilers on the market today directly absorb the existing oil in the oil pot into the oil nozzle through the piston, and then spray the absorbed oil through the oil nozzle. However, the form of most oils used on the market will change with the seasons. When the temperature is low in winter, most oils may solidify into a solid state, causing the solid oil to be extracted when the oiler is used, resulting in partial blockage of the oil nozzle, thereby weakening the sealing performance of the nozzle part, and then causing the oil nozzle part to be unusable. The article proposes that "therefore, it is necessary to design a pressure-resistant sealed oiler nozzle. Utility Model Content
