Circulating Water Chemical Dosing System, Have You Chosen The Right One?

Circulating water chemical dosing system is a commonly used dosing device. It is currently widely used in industrial circulating water, air conditioning water treatment, municipal water supply and drainage and other industries. Its process principle: During normal operation of the industrial circulating cooling water system, scaling or corrosion tendencies may occur due to the comprehensive influence of the temperature, hardness, PH value, concentration ratio, environmental source and other factors of the circulating water. The resulting scaling or corrosion will have a negative impact on the safety and operating efficiency of the circulating cooling system. In order to avoid scaling or corrosion, corrosion and scale inhibitors need to be added to the water manually or automatically. Currently commonly used corrosion and scale inhibitors include zinc salts, polyphosphates, polycarboxylates, membrane salts, etc.

Circulating water chemical dosing system: This device mainly consists of four parts: metering and dosing system, chemical liquid dispensing system, safety system and control system, etc. The process is: add the solid pharmaceutical into the dissolving tank according to the metered quantity, then add the industrial raw water according to the required proportion for stirring and dissolving. After the pharmaceutical is completely dissolved, use the metering pump to control the dosing system and add it to the dosage point of the pharmaceutical. . Dosing control includes manual dosing and mechanical automated dosing (automatic control and automatic dosing of chemicals based on the control signal output by the host system).

Issues that should be paid attention to when selecting a circulating water chemical dosing system include:

1. The ordered chemical dosing system consists of several dosing boxes and several metering pumps;

2. Determine the metering pump: whether to choose a plunger pump or a diaphragm pump for the metering pump;

3. What is the flow rate and pressure of the metering pump;

4. System control mode selection: The dosing system is determined to be manually controlled or automatically controlled based on a variety of factors;

5. Other aspects, usage location and environment, etc.
