A heat engine supplementary oil enthalpy-increasing circulation device with an ejector

Abstract

The invention discloses an oil replenishing enthalpy increasing circulation device for a heat engine with an ejector, which comprises a main body, an intermediate tank is fixed on one side of the main body by welding, and a check valve is provided on the inner wall of the top of the intermediate tank. The top of the one-way valve is connected with a regulating valve assembly through a pipeline, one side of the intermediate tank is connected with a vacuum pump, and the inside of the main body is provided with two upper and lower inner chambers with different diameters. The inside of the main body is provided with a piston assembly, and an oil outlet passage is connected between the main body and the intermediate tank. In the present invention, the piston assembly includes a piston body and a piston rod, and the piston body is slidably connected to the inner wall of the upper inner cavity. The piston rod is slidably connected to the inner wall of the lower inner cavity, the top of the main body is connected with an air supply plug through a thread, and the inside of the piston rod is movably connected with an adjustment rod through a bearing, which has strong practicability and can be adjusted according to the amount of oil shortage. Adjustment features.

Description

technical field [0001] The invention relates to the technical field of heat engines, in particular to a heat engine supplementary oil enthalpy increasing circulation device with an injector. Background technique [0002] A heat engine is any kind of machine that uses internal energy to do work. It is a type of machine power machinery that converts the chemical energy of fuel into internal energy and then into mechanical energy, such as steam engines, steam turbines, gas turbines, internal combustion engines, and jet engines. [0003] However, the existing heat engine supplementary oil enthalpy-increasing circulation device needs to refuel the oil tank once every few days. The oil supply method adopted is to directly pump oil to the wheel hub oil tank by starting the oil leakage pump, and the overflow oil of the wheel hub oil tank is discharged to Oil collection tank, this method cannot be automatically adjusted according to the oil shortage, and the practicability is poor. ...

[0003] However, the existing heat engine supplementary oil enthalpy-increasing circulation device needs to refuel the oil tank once every few days. The oil supply method adopted is to directly pump oil to the wheel hub oil tank by starting the oil leakage pump, and the overflow oil of the wheel hub oil tank is discharged to Oil collection tank, this method cannot be automatically adjusted according to the oil shortage, and the practicability is poor. Most of the existing oil return tank oil pressure display devices are electronic. Although they can respond to normal oil pressure, they are prone to failure after long-term immersion in high-temperature oil
