Taking the injection molding machine as an example, the process of the injection molding machine is generally divided into several stages such as clamping, injection, melting, pressure holding, cooling, and mold opening. Each stage requires different pressure and flow.
For the oil pump motor, the injection molding process is in a changing load state. In the hydraulic system of the quantitative pump, the oil pump motor provides a constant flow at a constant speed, and the excess hydraulic oil returns through the relief valve. This process is called a high pressure section. flow, this backflow causes energy loss. The use of frequency converters can solve this problem. By adjusting the speed of the oil pump, the oil pump can provide appropriate oil pressure at various stages of injection molding machine production, minimizing energy loss.
Some end users were the first to use frequency converters on eps foam building block equipment. System integrators provided them with frequency conversion and energy-saving transformation solutions for eps foam building block equipment, and the results were remarkable. Therefore, more and more eps foam building block equipment were introduced. Users of eps foam building block equipment have transformed their equipment with frequency converters.
