The outlet pipe of the U-shaped pipe is connected to a water outlet. A sewage outlet is installed at the bottom of one side side wall of the cooling oil tank. A sewage valve is provided on the sewage outlet. The inside of the cooling oil tank is connected to the inlet pipes of an oil pump and a standby oil pump. The outlet pipes of the oil pump and the standby oil pump are connected to the inlet of a filter. The filtered pipe of the filter is connected to the oil inlet of a plate cooler. The oil inlet is connected to an oil outlet. The oil outlet is connected to an oil supply port through an oil supply pipe.

[0006] A cleaning pipe is also provided at the front end of the filter inlet. The outlet of the cleaning pipe is connected to the rear end of the oil outlet. A cleaning valve is provided on the cleaning pipe.

[0007] An electric control box is also installed on the upper side wall of the cooling oil tank. The electric control box provides data lines to connect the oil pump and the standby oil pump. The electric control box is connected to a temperature sensor, a liquid level sensor and a pressure sensor through data lines.

[0008] The cooling oil tank is also equipped with a temperature sensor.

[0014] The oil supply port is connected to the inlet of the lubricating or cooling equipment.

[0015] Preferably, the coolant inlet of the plate cooler and the water inlet of the U-shaped pipe are connected to the output end of the water pump.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. The beneficial effect of the present utility model is that a U-shaped pipe is added in the oil tank to directly take away the heat of the oil in the oil tank, achieving a preliminary cooling effect.

[0018] 2. The plate cooler is used to replace the traditional pipe-type cooling device outside the oil tank. The plate channel of the plate cooler is designed in a corrugated shape, increasing the heat exchange surface area between the plates and improving the heat exchange efficiency.

[0019] 3. By setting a U-shaped pipe and a temperature sensor in the cooling oil tank, it is possible to prevent the cooling oil tank from being damaged due to excessive temperature, and by setting a liquid level sensor to monitor the oil level in real time, it is possible to prevent the U-shaped pipe from being exposed outside the oil, increasing the heat exchange efficiency and at the same time preventing the oil pump from idling. By setting a pressure sensor to monitor whether there is leakage or blockage in the pipeline.
