The auxiliary oil tank and the main oil pump 11 are connected to each other through a connecting pipe 2 15, and one end of the connecting pipe 2 15 is connected to the auxiliary oil tank through a fluid ejector nozzle 16.
[0024] The main oil pump 11 supplies oil, the bracket 17 is used to install and fix the auxiliary oil tank, the connecting pipeline 14 connects the main oil tank and the auxiliary oil tank, and the connecting pipeline 2 15 connects the oil supply pump and the auxiliary oil tank.
[0025] It also includes an oil level sensor 18, which is connected and installed at the top of the auxiliary oil tank;
