[CN 201721641776.7] Hydraulic oil cooling device of hydraulic press
[CN 201721641776.7] Title of Hydraulic Oil Cooling Device for Hydraulic Press: Application Number of Hydraulic Oil Cooling Device for Hydraulic Press: CN 201721641776.7 Applicant: Baoji Jinshengyuan Titanium Industry Co., Ltd. Application Date: 2017-11-30 Patent Type: Utility Model The utility model discloses a hydraulic oil cooling device for hydraulic press. A filter is arranged between the oil return pipe and the oil inlet pipe, and multiple heat exchange oil pipes are installed in parallel in the cooling water tank, the left end of each heat exchange oil pipe is connected with the oil inlet pipe through a vertical pipe, and the right end of each heat exchange oil pipe is connected with the oil outlet pipe through a vertical pipe. The end of the oil outlet pipe extending out of the cooling water tank is connected with the three-way pipe. One port of the three-way pipe is connected with the oil station through a pipeline, and the other port of the three-way pipe is connected with the oil inlet pipe through a return pipe, the temperature sensor is electrically connected to the solenoid valve through the microcontroller, the return pipe is provided with a return pump, and the temperature sensor is electrically connected to the switch of the return pump through the oil pump switch controller; the utility model has a simple structure and prolongs the residence of cold water in the cooling water tank Time, increase the contact area between the heat exchange oil pipe and the cold water, and improve the cooling efficiency.
