Using touch screen and PLC computer electronic control system, with leakage protection, multi-stage temperature display, over-temperature automatic alarm, with synchronous equipment operation signal display function. Electrical components must use well-known brand products, and bidders must provide detailed descriptions of computer motherboards, limit switches, low-voltage appliances, cables and wires.
2. Electrical control cabinet: an independent electrical control cabinet is required, which has the functions of electrical protection such as overload and short circuit and comprehensive control of the system.
3. The electrical control system should adopt international and domestic well-known brands such as Siemens, ABB, Omron, Schneider, etc. In order to ensure the reliable, safe and durable operation of the equipment, the electrical control system needs to provide a qualified inspection report from the quality supervision department.
4. The grounding protection of the metal shell of the electronic control device shall comply with the provisions of GBJ232.
5. Working voltage: 380 V 5% (three-phase five-wire system), 220VAC and 24VDC.
(9) Air supply system
1. Chimney: The total height of the chimney is not less than 10m, and the ejector base and chimney are made of 06Cr19Ni10 stainless steel plate with a thickness of not less than 3mm.
2. Air supply: the air volume is controlled by valves, and the combustion-supporting air duct is installed at the bottom of the furnace to ensure efficient combustion-supporting effect. The material is made of S31608 stainless steel pipe with high temperature resistance and corrosion resistance.
3 High-pressure fan is used for air supply, and shock absorber is used for shock absorption and positioning of the base.
4 air introduction: low-pressure fan is used, and the air outlet and pipeline are connected by high-temperature resistant hose; The base adopts shock absorber for shock absorption and positioning.
(10) Oil supply system:
