I. Introduction
The bipolar vacuum brick extruding machine is suitable for the production of various specifications of bricks such as shale, coal gangue and clay. The machine adopts the upper and lower level structure, which can be installed in one word according to the terrain. The upper and lower transmissions all use ZQ international reducer and axial start-up clutch, and the body is all welded with steel plates. The surface of the reamer uses a wear-resistant material spray welding process to extend the service life. Rugged and easy to operate. Can also produce various types of hollow bricks, a machine with more. The performance characteristics of the structure: Bipolar vacuum extruder consists of a bipolar stirring extrusion section (upper pole) and an extrusion molding section (lower pole), and is equipped with an air compression system and a vacuum pumping system. The machine adopts start clutch control. This article mainly introduces the field application plan of the easy-drive GT200 series inverter in the bipolar vacuum brick-squeezing machine.
Second, the bipolar vacuum brick working principle
After the raw materials are crushed, they are added with water, stirred, pressurized, vacuumed, extruded, and then coded and baked to form sintered solid bricks and hollow bricks with a certain strength, density and shape.
Third, the application program
At present, most brick-squeezing machines use the direct start of the power frequency or the auto-buck start-up mode. This kind of start-up inrush current is large, and the transformer capacity requirement at the front end of the equipment is increased a lot, and the frequent start-up impacts on the equipment. The wear is also great. At the same time, when the machine is not working properly, the machine is always in high-speed operation. The inverter is used to move the brick machine. When the machine start clutch is not closed, the empty motor runs at 30HZ and the machine is clutched. Together, the inverter quickly accelerated to 50HZ to meet the customer's energy saving requirements and reduce equipment wear and tear.
Fourth, easy to drive GT200 inverter features and advantages
Easy to drive GT200 series inverter is a universal high-performance open-loop vector inverter with advanced control performance such as large low-frequency torque, self-identification of motor parameters, optimal acceleration and deceleration control, and wave-by-wave current limiting; with powerful I/O expansion Function, support a variety of communication control card, can customize the process control card and other extended functions for the customer; have the function to meet different process requirements, such as the pendulum frequency control, multi-segment control, simple PLC control and some practical functions. It can be used in the drive of automation products such as machine tools, cables, textiles, foods, chemicals, etc. to meet the needs of different industrial equipments for performance and function.
V. Field application

Sixth, summary
Easy to drive GT200 series inverter, speed range, high speed accuracy, high operating efficiency, mechanical properties, hard, static stability, start, brake energy consumption is small, non-polar speed. Therefore, the use of frequency converter for AC three-phase asynchronous motor for speed control has been widely used.
