In recent years, with the development of informatization of electronic equipment, there has been an increasing demand for processing various heat-sensitive polymers as physical transmission media. Such as PVC cable, PE silane, peroxide cross-linked cable, PE cross-linked shielded cable, etc. The key to the production of these polymers is the extruder. The extruder is constantly evolving with the increasingly high time-sensitive production requirements, from the previous DC motor to the inverter with the asynchronous motor, and then to the rare earth permanent magnet synchronization
Extrusion equipment is usually composed of the main machine, an auxiliary machine, and a control system. The extrusion system is mainly composed of screw and barrel, which is the key part of the extruder. The function of the transmission system is to drive the screw, which must ensure that the screw has the required torque and speed during the working process; the heating and cooling system mainly ensures the temperature control of the material and the extrusion system in the molding process. The composition of the auxiliary machinery of the extrusion equipment depends on the type of product. The main function of the control system is to control the speed of the main drive device, display its speed and current, and control the temperature.
DC motor and asynchronous motor drive screw have the following shortcomings:
The emergence and development of synchronous motors have made a considerable contribution to the abundance of power resources in our country. Compared with asynchronous motors, they have obvious technical and economic benefits and have the following advantages:
The AC310 series inverter is a product continuously developed on the latest high-performance vector technology platform of VEICHI. It not only adopts the international leading field-oriented vector control technology to be compatible with synchronous and asynchronous motor control but also has the advantages of under the premise, rationally arrange the parts and realize the book-style narrow body design.
Set according to the parameters in the table, the motor parameter self-learning must be carried out, and it is recommended to disconnect the motor shaft for rotating self-learning.
