[CN 201620038368.1] Process water cooling system of hydraulic press and spot welding machine


[CN 201620038368.1] Title of Process Water Cooling System for Hydraulic Press and Spot Welding Machine: Application Number of Process Water Cooling System for Hydraulic Press and Spot Welding Machine: CN 201620038368.1 Applicant: Shandong Gred Group Co., Ltd. Application Date: 2016-1-16 Patent Type: Utility Model The utility model relates to a process water cooling system for hydraulic press and spot welding machine, including a hydraulic press and a process water cooling system for circulating and cooling process water, the process water cooling system of hydraulic press and spot welding machine includes chiller, cooling tower and plate heat exchanger. The process production line of hydraulic press and spot welding machine is connected with chiller through plate heat exchanger to cool the process water. The chiller is connected with cooling tower to circulate the cooling water of chiller. The cooling tower is also connected in series with hydraulic press and spot welding machine process production line to cool the process water, when the ambient temperature is low in the transition season, the chiller needs to be started to cool when the cooling tower cannot reach the process temperature. At this time, the cooling water temperature of the chiller is low and the chiller cannot be started normally. Auxiliary electric heating measures are adopted to make the unit work normally.
