Abstract

The utility model discloses a lubricating oil auxiliary system used in diesel bench tests. The lubricating oil auxiliary system comprises an oil supply oil tank. A lubricating oil return line is formed by the oil supply oil tank and a diesel through an oil pumping pipeline and an oil return pipeline. A valve, an auxiliary pump and a temperature-sensing valve which are close to the oil outlet of the oil supply oil tank are arranged on the oil pumping pipeline successively. The temperature-sensing valve is connected with a heat exchanger for providing refrigerant for the temperature-sensing valve. The auxiliary pump is connected in parallel with a pre-supply pump. A pressure regulating branch provided with a pressure regulating valve is further arranged on the oil pumping pipeline. The pressure regulating valve is used to return oil to the oil supply oil tank through the pipelines. The pressure tapping end of the pressure regulating branch is arranged between the auxiliary pump and the temperature-sensing valve. According to the utility model, not only test requirements of a diesel which is provided with a lubricating oil pump can be satisfied, and but also test requirements of a diesel which is not provided with a lubricating oil pump can be satisfied, so that the functions of test bench lubricating oil auxiliary system can be increased, and the production cost is reduced.
