Overview of dosing devices
Dosing equipment is added kits, metering pumps (diaphragm), automatic control system integration, that is mounted on a base, the metering pump (piston pump) export pipeline and dosing, metering box and into the import and export pipes connected, and the control cabinet power and instrumentation signals to the control cabinet can start, put into operation. Automatic dosing equipment is widely used in electric power, petroleum, chemical industry, metallurgical industry, environmental engineering, water treatment and other fields. For best results, in case conditions change, the increase of the automatic tracking adjustment of chemical dosage control dosing rate, so that dosing device, we adopted the advanced automatic control mode to control the dosage. In addition to part of the dosing pipe, pipeline and processing concentration sampling instrumentation, these dosing devices are generally installed in a concentration within a dosing, dosing equipment, the company completed the purchase, manufacture, assembly, commissioning, trial run, Users simply combined automatic dosing device placed between the post-dosing. This can greatly reduce the on-site construction work, to avoid errors in the middle part of many leads as well as passing the buck between each other, effectively ensure the schedule and project quality, reduce the user the trouble and loss.
Dosing device structure
Automatic control device consists of automatic control cabinet, recorder, AC motor, dosing pumps and other components. Automatic control cabinet with inverter, regulator, detector, etc., below. Detector by the user's choice of type of dosing decisions, such as: Ammonia, the detector can be used conductivity meter or PH meter, plus the choice of fast phosphate phosphate analyzer, and the pool can be used in the PH meter, coordinated phosphate R was needed to deal with the table, then use the flow of current coagulation analyzer, chlorine residual chlorine need to configure the table and so on.
