In the injection molding workshop with injection molding machine equipment, circulating cooling water plays a very important role in the injection molding machine. It mainly supplies the injection molding oil cooler and peripheral auxiliary equipment, such as mold temperature machine, chiller, barrel cooler and other devices for replacement. heat to meet the temperature control requirements of the injection molding process and ensure the normal operation of the hydraulic system of the injection molding machine. In order to reduce the energy consumption of the system, it is very important to rationally design the cooling water circulation system of the injection molding workshop. At present, most injection molding machine production workshops supply cooling circulating water to each injection molding machine in the injection molding workshop by using one water supply pump or two or several water supply pumps in parallel, which often occurs because the power of the water supply pump is too small, or the pipeline The deviation of resistance results in insufficient cooling water flow of the injection molding machine far from the water supply pump, so that the hydraulic oil of the hydraulic system of the injection molding machine cannot be cooled in time, resulting in machine failure, or when the oil temperature of the hydraulic oil exceeds 55 degrees Celsius, The electrical control system of the injection molding machine with temperature protection enters the protection state and stops.

In addition, if the injection mold is not cooled by the circulating cooling water in time, the cooling time of the production process will be prolonged, the production efficiency will be reduced, and the plastic products produced will be defective or even scrapped. If a high-power, large-flow water supply pump is used in actual production, the energy consumption will be too large, and the production cost will increase, especially when there is only one or several injection molding machines in the workshop, it is also necessary to run a high-power water supply pump, resulting in energy consumption. waste. As for the frequency conversion control circulating water supply system, due to the high price of the frequency conversion system, the high technical requirements for the maintenance of the electrical control system, and the heavy burden of small and medium-sized enterprises, it is rarely used at present.
