1. The sludge drying equipment manufacturer introduces when troubleshooting the municipal sludge drying equipment, pay attention to the use of existing resources. Modern control systems are becoming more and more complex. If executed correctly, this complex benefit and simplified operation will bring many benefits. The cost of a programmable logic controller (PLC) has been reduced to the economic advantage of using the technology frequently, and solid-state controllers also provide additional and improved features.
2. Familiar with programs or hardware schematic diagrams and logic methods. Electrical signals often affect the fuse, and some instruments fail in a fault state and will not cause the system to alarm. Wires may be loose, opening a circuit that should be closed under operating conditions, these will have an impact on production, often manifested in strange performance, there are many possibilities for control failures that may lead to poor operation, familiarity with the logic of the control system is essential for success It is very important to eliminate poor performance.
3. The sludge drying equipment manufacturer introduces suitable tools. This is self-evident, in order to solve the failure of the dryer, the correct tools include meters, such as multimeters, pressure gauges, ammeters and thermometers. Other instruments include: tachometer, anemometer (blade or hot wire), micromanometer, pitot tube and infrared thermometer.
