One, common form
1, chemical filling water, water and ammonia system
Add ammonia system can realize automatic control; Ammonia liquid preparation can also be except the manual preparation for automatic control, when the solution tank liquid level is lower than the set value, automatic open solution tank inlet valve and the high level automatically shut down, and control the amount of ammonia in addition to the manual control for automatic control, the PLC program control system controlled by the frequency converter after PID arithmetic plus ammonia metering pump and amount of ammonia to achieve the purpose of automatic dosing.
2, boiler water and phosphorus salt system
The confecting of phosphate, trisodium phosphate, directly add solution box dosing, start mixing with machine to dissolve, and phosphate salt can also be except the manual control for the control of automatic control and the PLC program control system by frequency converter after PID arithmetic to control the amount of phosphorus metering pump to achieve the purpose of automatic dosing.
Second, the order information
1, the ordering system for a few box pump.
2, metering pump, plunger pump or diaphragm pump.
3, metering pump flow and pressure.
4, the system is manual or automatic control
