Delta's VFD-VJ series of servo drive has been highly favored by the market since its launch, with the advantages of power saving, precision, and high response, and has been rapidly developed in the application of multi-pump splitting and confluence in large injection molding machines. Recently, Delta successfully provided a four-pump converging oil-electric servo drive solution based on the VFD-VJ series of servo drives for a customer's two large injection molding machines. It fully meets the needs of customers and is highly recognized as a customer. Exploring the international market provides powerful support. The two large-scale horizontal injection molding machines produced by the customer meet the needs of different flow rates and pressures in the production process by means of four-pump split-confluence. At the same time, in order to meet the high-end use requirements of customers in the international market, the hydraulic system is also energy-saving through the oil and electricity servo system. The specific requirements are: the equipment system pressure is 175Kgf, the system flow rate is 900L/min, and the electric servo drive has the function of combining and splitting. In order to realize the pre-molding, mold opening, ejection and other actions in the same move, the drive is required to have multiple sets of PID functions. In order to meet customer requirements, Delta's application engineers used four VFD-VJ series servo drive units as the four-pump converging electric servo drive scheme for each device. Together with the existing motor and oil pump of the customer, each unit formed Four-pump confluence system for equipment. Through the confluence operation, the injection molding machine can meet the large flow requirement of the rubber injection operation and the pressure at the time of pressure maintenance; through the shunt operation, the linkage between the mold opening, the mold holding and the melt movement can be realized. The structure diagram of the four-pump sub-convergence system of Delta's electric servo drive scheme is as follows: (Note: A, B, C, and D represent workstations formed by VFD-VJ series servo motors and corresponding motors and oil pumps, respectively. P1, P2, and P3 are pressure commands issued by the upper controller. Q1, Q2, Q3 is the flow command issued by the upper controller. PO1, PO2, and PO3 are pressure feedback, SON is the enable signal, and MI3 is the shunt signal. After on-site commissioning, Delta's four-pump converging oil-electric servo drive scheme fully meets the requirements of customer system pressure, flow, and multi-action synchronous operation, and the pressure relief speed problem proposed by customers also reduces slump parameters by adjusting the deceleration time and flow command. The perfect solution, while providing accurate pressure and flow control, not only greatly reduce energy consumption, and save operating time, shorten the entire process cycle, increase production, maximize customer benefits. As the core of Delta's four-pump converging oil-electric servo drive scheme, the VFD-VJ series of servo drive has become an important driving force for high-end injection molding machines to open up the international market with excellent and stable performance. It also expects to work together with customers to achieve common goals. For the international market to create high-quality injection molding machine products.
