Rich students view of an automatic dosing device Which Putian automatic dosing device

Automatic dosing unit detailed instructions 1, the first water treatment chemicals should be added to storage tanks, to observe the magnetic level gauge, according to the requirements of reagent concentration diluted with water. 2. Open the instrument control cabinet, turn on the main power switch, the main power indicator light, current voltmeter indication that normal supply. 3, open the "stirring" switch, the stirrer is started (100 rpm / min). 4, the "manual / automatic" switch to "manual" position, then open the "dosing" switch, dosing pump to work, the metering pump pulse frequency display, and you will hear the sound of the diaphragm vibration, indicating that the metering pump is working properly . 5, metering pumps up to 120 pulses, the viscosity of the agent is not the same per minute, metering pump out fluid volume is somewhat different, because the first time dosing by meter measurement, calculates the amount of liquid per minute, or liquid amount per pulse, and then adjust the dosage according to the metering pump pulse frequency. 6, after the above steps are completed, the device operating in "manual" state operation has ended, normal dosing device. As time without dosing, the relevant metering pump switch can be turned off to stop dosing when dosing For, as long as the timer to adjust the meter cabinet to the desired start time quantitative, stop time, then the "manual one Auto "switch to" Auto ", the timer starts working, the device enters the automatic operation state. 7, usually as long as the timing of adding the liquid to ensure that no-load operation can be. 8. If the equipment is running, there is a failure, please be professional exclusion, or contact us. Interference automatic dosing unit automatic control system problem is: 1, the water contains a lot of organic pollutants in waste water produced by paper mills, chemical coagulation agent is an organic polymer or strong adhesion agents will stain the flow of current sensor probe, resulting in detection signal distortion, drift, causing the control system does not work properly, so when should replace the current sensor probe, required to be replaced once a year. 2,3M sensor signal and control adjustment signals are weak signal, so once There are strong signals in the vicinity of the sensor or control the flow of the current control system cables exist, it will cause interference, affecting the normal operation of the control system. There are sensors ground to meet the requirements, the power supply is disturbed, the control system will cause damage shield interference with the flow of the current control system, affecting the normal work flow SCD Dosing automatic control system.
