Product Description

Dosing Device

The SZJY series dosing device adopts a unit system design, and all components and parts within the independent unit, such as solution tank, liquid level gauge, metering box, agitator, dosing metering pump, control cabinet, valves, and pipelines, are centrally arranged and integrated. The complete dosing device can be composed of several units. A filter is installed at the outlet of the solution tank to prevent blockage and equipment failure. Solution configuration magnetic flap liquid level indicator, high and low liquid level alarm, low liquid level automatic pump stop to prevent the metering pump from idling. It can be manually dispensed or automatically dispensed through electromagnetic valves according to different requirements. There are three control methods: on-site manual, on-site automatic, and remote control.

Dosing devices, also known as dosing systems or chemical injection systems, are widely used in various fields, including water treatment, wastewater treatment, industrial production process control, etc. Their main function is to precisely add chemicals to fluids to achieve specific treatment effects. Here are some specific application scenarios:

1. Water treatment: In the process of drinking water treatment and industrial water treatment, dosing devices are used to add coagulants, flocculants, disinfectants (such as chlorine), etc. to remove suspended solids, bacteria, and other harmful substances from water.
2. Wastewater treatment: In sewage treatment plants, dosing devices are used to add alkaline substances to adjust pH, add coagulants to promote precipitation, add disinfectants to kill pathogens, etc., to ensure that the discharged water quality meets environmental standards.
3. Industrial production: In industries such as chemical, pharmaceutical, and food processing, dosing devices are used to add catalysts, stabilizers, preservatives, etc. to optimize the production process or improve product quality.
4. Swimming Pool Maintenance: In swimming pool management, the dosing device is used to automatically add chlorine or other disinfectants to maintain clean and hygienic water quality.
5. Cooling tower maintenance: In industrial cooling systems, dosing devices can add anti scaling agents, disinfectants, etc. to prevent equipment corrosion and scaling, and extend service life.
6. Agricultural irrigation: In some cases, dosing devices can also be used in agricultural irrigation systems to add trace element fertilizers or plant protection products to improve crop growth conditions.
