ACCESSORIES OF SURFACE COATING PLANT
SCADA
- Programmable PLC Control for all blowers, Pumps, Burners etc.
- Panel consists of PLC based control system. Auto sequencing is synchronized movement to perform time based spray treatment of material. Sequence execution reliability is provided by PLC whereas precise control over transverse motion is achieved through variable frequency drive.
- PLC and SCADA based front end application. For various interlocks, time delays, sequence etc. logic is written in PLC program. SCADA based front end application i.e. software is developed and installed in a computer.
- This is used for display of various values and status.
- Commands are given through icons created on the computer screen.
- Changes can be done though SCADA program.
- Also HMI screen is provided on control panel
- MIMIC System of the total plant will be provided to see the total layout of the plant. LED indicators are provided which will indicate the running plant.
INDIRECT HEATING SYSTEM
Indirect heating system is provided for phosphate tank. It mainly consists of PHE, 3- way pneumatic valve and warm water tank. Water in warm water tank is heated using direct fired heating system. Heated water then circulated to PHE using 3-way pneumatic valve. Phosphate chemical is also circulated to PHE and heated chemical returns to chemical tank. Chemical gets heated due to heat transfer from warm water in PHE. Once desired temperature reached, 3-way pneumatic valve cut off the flow of warm water to PHE.
