DSPC170 ABB 数据输入模块 利用直线电机所产生的电磁力

DSPC170

This device mainly uses the electromagnetic force generated by the linear motor to push the tin liquid in the tin tank to flow slowly along the prescribed direction in advance and balance the stirring temperature of the tin liquid in the tin tank; Thus, the temperature of the tin liquid in the high temperature area of the tin tank and the tin liquid in the low temperature area is uniform, reducing the temperature difference in the tin liquid, eliminating the uneven thickness of the glass and warping phenomenon; Make the glass after forming evenness, so as to improve the glass forming quality. Skimming machine is under the action of specially designed ash retaining facilities; The tin ash on the surface of the tin liquid is concentrated in the ash outlet and pulled out. The use of these two kinds of equipment, greatly reduce the glass in the forming of defects, improve the yield, it has become a modern float glass line must be equipped with devices.

The main domestic suppliers of linear motor and skimming machine are Lobo Group Luoyang Xike Glass Automatic Control Equipment Co., LTD. And Qinhuangdao Glass Industry Research and Design Institute Qinhai Kiln Co., LTD. (5) Industrial monitoring and transmitter. At present, the internal condition monitoring of high-end float line tin groove mainly uses foreign high-precision endoscopic cameras, such as the endoscopic monitoring system of German SVA company, which has a good effect on the application of multiple float lines in China. It is used in conjunction with the automatic edge pulling machine, which can well monitor the edge pressing and operation of the edge pulling machine head, as well as observe the condition of the glass belt in the groove. There are also some domestic companies producing endoscopic cameras, but their reliability in float glass production and application needs to be further observed. Transmitter including pressure, flow, analyzer and temperature, the current use of pressure and flow transmitter using foreign transmitters, especially the measurement of differential pressure.

For example: Rosemount, Yokowaga, Siemens, etc.; Oxygen analyzer uses domestic and foreign, domestic generally can meet the requirements; Temperature sensor adopts domestic thermocouple, precision and reliability can meet the requirements. However, the domestic transmitter still needs to be improved in terms of communication and intelligence to meet the requirements of bus and high precision in the future. (6) low-voltage electrical appliances. At present, most of the low-voltage electrical appliances used in float glass production lines are the products of ABB, Siemens, Schneider and other famous foreign companies. Most of these products have been assembled or produced in China at moderate prices. Of course, the quality of many domestic low-voltage electrical products has been greatly improved and improved a lot, I believe there will be opportunities to get a large number of use.

Electrical cabinets require CE or UL certification abroad, so for export projects, be sure to use products that meet the requirements to avoid trouble. At present, Shanghai Witu cabinets and Suzhou Schneider cabinets have CE certification and can be used. C. Cold end electrical automation equipment. Cold end is the section with the highest degree of automation in float glass production. In the production of modern float glass, it is required that the cold end section can realize the automatic detection of glass defects online, marking, optimization cutting, deviation tracking, speed improvement, multi-specification longitudinal division, automatic steering and automatic stacking. Broken glass system to achieve feeding, feeding automatic interlock control, to ensure that broken glass does not fall. Under the control of computer, the automatic defect detection system uses image recognition and processing technology to detect and classify the defects.

Communicating with automatic marking equipment, marking machine can spray corresponding glass grade mark on the surface of glass plate according to the signal of judging the glass. The automatic defect detection system is connected with the cutting control system, and the cutting control system can optimize the cutting control of glass plate and improve the yield. Cutting control system with man-machine interface and upper control system, mainly for measurement, longitudinal cutting, transverse cutting, transverse acceleration and edge breaking control system coordination control and management.
