Easy drive CV3100 series inverter 280KW in the foaming machine equipment application

I. Introduction:

 EPE Pearl Cotton Foaming Machine is a special equipment used to produce EPE Pearl Cotton Sheet.It melts DPE resin and mixes it with butane, talcum powder, anti-shrinkage agent and other additives, extrudes it through extruding mechanism, and foams it in the part of die head and die lip, and finally cools and extends it into fixed size pearl cotton sheet through wind ring and shaping ring, and the final product is rolled up by charging roller.

 Second, the company introduces: Chongqing Jiecheng Plastic Equipment Factory has long been committed to the research and production of sponge series products, the main types of products and characteristics of polyester sponge, polyether sponge, closed-cell sponge, open-cell sponge, packaging shockproof sponge, super-soft hardened sponge, high-density sponges, sound insulation sponge, composite adhesive sponges, conductive and anti-static sponges, colours and colours of the class of sponges, the shape of the deep processing categorySponge, rubber-plastic foam sponge and a large number of production of mechanised continuous assembly line foam sponge materials, high-quality sponge products and their products, to provide high-quality flat foam, round foam, net foam, high elasticity, high load-bearing and other high-quality sponge and its rubber-plastic foam products.

 Third, the use of easy drive frequency converter in the foam machine on the advantage of analysis

 1, frequency conversion technology can effectively control the motor speed, with a wide range of speed control, high precision speed control, fast dynamic response and other advantages;

 ●Running speed adjustable: frequency conversion technology in adjusting the output frequency at the same time in proportion to adjust the output voltage, so as to change the motor speed, to achieve stepless speed regulation;

 ●Controllable acceleration: the frequency conversion speed control can be started at zero speed and accelerated according to the demand, and the acceleration curve can be selected according to the design demand;

 Adopting microcomputer control technology to control the frequency converter can realise a variety of transmission speed regulation functions: various frequency setting and execution, starting, operation mode selection, torque control setting and operation, acceleration and deceleration design and operation, braking mode setting and execution, so that the frequency conversion technology is more intelligent, and the field of application is broader.

 2. The protection function of frequency conversion technology is more perfect, and it can effectively control the protection and monitoring of motor, the life of mechanical parts, and the current and voltage fluctuation of the power grid; in terms of the loss of mechanical parts, the selection of motor stopping mode (deceleration stopping, free stopping, deceleration stopping with DC braking, etc.) by frequency conversion can reduce the impact of the motor and its linkage of mechanical parts; and dynamic adjustment of the torque limit can avoid the mechanical noReduce damage. 3, frequency conversion technology has significant advantages in energy saving and maintenance.

 Firstly, frequency conversion technology realises soft start and small starting current.Motor power is proportional to the product of current and voltage, and the power consumed by the motor started directly by industrial frequency will be much higher than the power needed for frequency conversion start;

Secondly, the frequency conversion speed control motor operates at a low turnover rate, reducing the motor's own loss and high efficiency.At the same time, with the changes in application requirements, frequency conversion speed control system can quickly and dynamically adjust the speed to the lowest power consumption.

 Fourth, easy drive CV3100 frequency converter features

 1、V/F control mode (can achieve one tow more) A. Advanced vector control algorithm, optimised SVPWM output, low output harmonics, small motor temperature rise. B. Optimum energy-saving operation is achieved through motor parameter detection.

 2、Open loop vector control (SVC) mode A. Adopting TI high-speed motor control special DSP processor, it can complete the complex vector calculation with high speed and accuracy, and realise the complete decoupling of the motor. B. Adopting advanced motor modelling algorithm, it can output 150﹪ rated torque at 0.5Hz, with 0.5﹪ accuracy of speed regulation and 1:100 speed regulation range.

 3、Standard RS485 interface, support MODBUS communication protocol, and the upper computer such as touch screen, PLC and other network communication.

 4, perfect protection measures can be achieved over-voltage, under-voltage, input phase loss, output phase loss, overload, overheating, overcurrent, external terminal failure, communication failures, current detection errors, motor tuning faults, such as nearly 20 kinds of fault protection, higher reliability. Fourth, easy drive CV3100 series frequency converter used in foaming machinery on the scene picture

 Six, easy drive CV3100 series frequency converter used in foaming machinery and equipment, so that the system reduces energy consumption, save operating costs, energy saving and environmental protection.
