Metering pump dosing device selection of electromechanical integration structure, assembly can be divided into mobile and moving (trolley type). Each dosing device is equipped with a mixing system, dosing device and control system. A number of fixed and stationary guides can be composed as a whole and composed with a frequency conversion automatic control system, which can achieve local control, remote control automatic control system, manual and automatic mutual transformation management methods. It has the characteristics of compact structure, small size, low noise, stable work, simple assembly and convenient operation. Metering pump manufacturers to take you to understand

Analyzing the circulating water system of the dosing device of the metering pump is very easy to have any problems:

1. Corrosion: When the cooling water is circulating, the air and water in the automatic dosing device touch each other, the dissolved oxygen in the water is becoming more and more over-saturated, and the dissolved oxygen in the water causes corrosion of metal materials such as carbon steel and pig iron. 

2. Scaling: Because of the continuous evaporation of water in the automatic metering pump dosing device, the salt content in the circulating water is significantly increased, and the calcium carbonate and calcium bicarbonate in the water are significantly increased, resulting in scaling on the surface of the pipeline and uneven surface heat transfer.

3. Pulverized coal: Cooling water digests and absorbs a lot of dust, gravel, microbial strains and other inorganic and organic matter in the air. Because the sun exposure, ambient temperature, oxygen content in the cooling tower are very suitable for the growth and development of bacteria and algae, the mud in the system software is promoted, resulting in damage to the system software.

Application range of dosing device:

1. Sewage treatment needs to add coagulant, diatomite filter aid, disinfectant, acid, alkali and so on.

2. Add anti-scale agent to cooling water and circulating water.

3. In chemical plants, paper industry, packaging printing, printing and dyeing plants, plus strong acid and alkali aqueous solutions and other aqueous solutions.
