product description
    Nowadays, the Dele large-circle knitting machine that is more frequently used in the textile industry, the Struckmeier Gmbh frequency converter, which is equipped with it, often breaks down due to a long time of use. This brand frequency converter does not have an agent in China, and there is no maintenance service department. Machine maintenance, maintenance, spare parts supply, repair and other aspects have brought many inconveniences. In order to ensure the smooth progress of the user's production, we have tried our best to meet the user's maintenance requirements, but still cannot be repaired due to the supply of parts and the aging of the machine. In order to facilitate the user's choice and consider the user's cost, our company independently developed a new electrical control system with Danfoss inverter as the main component. The system uses the original control mode and only replaces the frequency conversion part. The SX-YJBP-4 large circular knitting machine frequency conversion system has been tried out by Lima (Suzhou) Chemical Fiber Textile Industry Co., Ltd. and Shanghai Three Gun Knitting Co., Ltd., and its performance has completely copied the original functions. In actual operation, the operator does not need to be retrained. , Fully follow the original operating habits, and the maintenance work is also quite convenient for installation and commissioning.
    The frequency conversion system of SX-YJBP-4 large circular knitting machine selects Danfoss VLT2800 series frequency converter, which has the characteristics of compactness, light weight, convenient use and precise control. This product is a general-purpose series produced by Danfoss, Denmark. It has strong motor dynamic and static performance, excellent low-frequency performance, and excellent self-stability. According to the actual load condition of the motor, the speed of the motor can be appropriately controlled, and the speed of the motor can be controlled efficiently. Danfoss VLT frequency converter is a significant feature. Danfoss inverters have now become synonymous with precision, reliability and smooth operation. Like other inverters, Danfoss inverters are specially designed for three-phase AC motors that are widely used in all modern factories. Danfoss VLT frequency converters are also widely used in the textile, heating, heating, ventilation and air conditioning (HVAC) industries.
   The main features of SX-YJBP-4:
1. Flexible operation, by programming the parameters, it can meet the setting requirements of different applications of the large circle knitting machine, and it can also be set quickly through the "QuickMenu" button
   Menu, simple setting of no more than 9 parameters, can be suitable for most applications. Plug-in control terminals can be easily and quickly disassembled and frequency conversion.
2. Durable, built-in braking unit, DC reactor, cooling fan, fully meet the application requirements of various types of large circular knitting machines.
3. The built-in RFI radio interference filter will not cause interference to other electronic equipment (relatively), and can resist the interference of other electronic equipment to VLT.
   Comply with EN55011 class 1A, radiation and conduction standards.
