The bipolar vacuum brick extruder is suitable for producing various specifications of bricks with raw materials such as shale, coal gangue and clay. The machine adopts the upper and lower structure, which can be installed in one word according to the terrain. The upper and lower transmissions adopt ZQ type international reducer and axial start clutch, and the body is all welded by steel plates. The surface of the reamer is spray-welded with wear-resistant materials to extend the service life. Rugged and easy to operate. It can also produce various types of hollow bricks with one machine for multiple purposes. The performance characteristics of this structure: The bipolar vacuum extruder is composed of a bipolar stirring extrusion part (upper pole) and an extrusion molding part (lower pole), and is equipped with an air compression system and a vacuum system. The machine adopts starting clutch control. This article mainly introduces the on-site application scheme of Yidrive GT200 series inverter in the bipolar vacuum extruder.
2. Advantages of Yidrive GT200 series frequency converter in brick extrusion machine application equipment
At present, most brick squeezing machines adopt power frequency direct start or auto-coupling step-down start method. This kind of start-up inrush current is large, and the requirement for the transformer capacity at the front of the equipment has increased a lot, and frequent start-up has an impact on the equipment. The wear is also great. At the same time, when the machine is not working normally, the machine is always in high-speed operation. Use the frequency converter to drive the brick squeezing machine. When the machine is started and the clutch is not closed, the empty motor runs at 30HZ, and the machine is clutched. Together, the inverter quickly accelerates to 50HZ, which meets the customer's energy-saving requirements and reduces equipment wear.
