Why is the dosing device of the metering pump reasonably designed and feel the need to give you science: Strong alkali sodium hydroxide solution is corrosive, pharmaceutical equipment operators need to ensure safety, good alkali solution diluted in a unique container, during this period the solution temperature will be greatly increased, when the alkali temperature drops to normal temperature, or anti-corrosion lift pump into the solution tank, or manual lye directly into the solution tank, to avoid alkali liquid splashing in the body. When the alkali adding equipment works, the PLC starts the automatic control system, the agitator works first, mixes the lye well, and then begins to measure, so the design of the automatic dosing device is more reasonable. Dosing device is a chemical water treatment device used to lift the water circulation system. The principle is to control the chemical dose of the circulating water system by the online detection system and the automatic dosing system to prevent the accumulation of scale, erosion, biological clay and bacterial algae in the water circulation system.

The control measures of dosing device of metering pump are mainly divided into: Manual control, automatic control, automatic control, time level control, PH control, conductivity control, etch online monitoring control, drug concentration online monitoring control and other different control measures, how to choose the appropriate control measures mainly depends on the customer site requirements, different water without drug selection control measures are different, so we need to ask the design technology needs, Otherwise it might be busy. Check dosing equipment before starting:

1. Check all pipelines and the gate valve works normally.

2, check the dosage pump of each dosing equipment, stirrer work normally.

3. Check that the electrical equipment is in normal operation. Real-time tracking of water changes, water sampling, testing and analysis, the controller according to the water quality and the operating status of the air conditioning system, automatically and quantitatively add scale and corrosion inhibitors, bacteria and algae and other drugs to the water system to achieve the effect of water treatment. Taking the conductivity and concentration ratio of cooling circulating water as the detection target, the water quality of circulating water is measured by measuring the conductivity of circulating water, and the signal of drugs and wastewater is transmitted. The drugs and wastewater are completed by peripheral equipment, so as to realize the automatic operation of the system, achieve the removal of bacteria and algae, anti-scale and turbidity mitigation, while maintaining the concentration ratio.
