Automatic dosing device detailed instructions 1, the first water treatment chemicals should be added to storage tanks, observed magnetic level gauge, according to the requirements of drug concentration diluted with water. 2. Open the instrument control cabinet, turn the power switch, the main power indicator light, current and voltage table indicating the automatic dosing device, said the power supply is normal. 3, open the "stirring" switch, the stirrer is started (rotational speed of 100 / min). 4, the "manual / automatic" switch to "manual" file, and then open the "dosing" switch circulating water automatic dosing equipment, dosing pump to work, metering pumps display pulse frequency integrated automatic dosing device and listen to the diaphragm vibration sound, indicating that the metering pump is working properly. 5, metering pump up to 120 pulses, the viscosity of the agent is not the same per minute, the amount of liquid metering pump is somewhat different, because the first time with a dosing meter measurement, calculates the amount of liquid per minute, or liquid volume 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 the "manual" state operation has ended, normal dosing device. Such as without dosing, metering pump switch to turn off the relevant dosing can be stopped, and if the time dosing, as long as the timer to adjust the meter cabinet to the desired open time quantitative, stop time, then "a manual Auto "switch to" Auto ", the timer starts to work, the device automatically enters the running state. 7, usually as long as the timing of adding the liquid, you can ensure that no-load operation. 8. The device is running, there is a fault occurs, professionals should be excluded, or contact us. Phosphate automatic dosing device process principle boiler feed water calcium and magnesium hardness occurs at high temperatures chemical reaction, or the concentration of crystalline form insoluble scale, firmly attached to the boiler heating surface, this scale is a poor conductor of heat, hinder heat conduction, serious accidents can occur boiler tube, in addition, will induce and exacerbate under the scale metal chemical corrosion, damage is very serious. Although the boiler condensate, water went through a rigorous softening, desalination treatment, but there is still a small amount of calcium and magnesium hardness of water into the oven, if you do not deal with this part of the hardness will scale threat to the safe operation of the boiler, the current automatic Dosing devices offer, plus phosphate boiler water is the most appropriate approach, the reaction is as follows: 10Ca2 ++ 6P04 a + 2OH-- Ca, o (OH) 2 (PO4) 6 (dibasic calcium phosphate) is a basic calcium phosphate a soft water residue, sewage exclude easy with boiler and does not adhere to the pot into a scale. Phosphate automatic dosing device Workflow Overview This device includes four parts liquid solvent distribution system, metering dosing systems, security systems, and control systems. Solid phosphate added to dissolve the medicine cabinet, then, to add demineralized water or condensate stir to dissolve, added by metering dosing system within the boiler drum. Dosing can be manually controlled, but also the control signal based on the output of the host system, and conduct follow-up control, automatic dosing. Phosphate automatic dosing device Scope pressure and higher drum boiler water treatment parameters.
