Complete set of dosing devices includes the following three categories: simple dosing device, integrated dosing device, splitting dosing device
The simple dosing device is equipped with the small dosing pump, stirrer, level switch and other accessories. They all are directly installed in the dosing barrel. With flexible allocation, small space occupation, high cost-effectiveness, it is very suitable for the small dosage. Other optional accessories: injection valve, pulse damper, counter balance valve, control cabinet and so on.
Integrated dosing device refers to integrated installation, that is, solution tank, stirrer, level gauge, dosing pump, control cabinet, platform escalator and other supporting accessories (such as safety valves, dampers, check valves, etc.) all are installed on a channel base.
According to the combination of dosing device, it covers various kinds, such as "one tank-one pump", "a tank-two pumps", "two tanks-two pumps", "two tanks-three pumps", "two tanks-four pumps", and multi-tank with pumps, etc.
According to the control mode, it includes basic type and smart type. The basic type is an open-rack dosing control system. The necessary accessories can be selected to meet the more accurate dosing requirements.
Smart dosing control system refers to open-loop control of achieving a fixed proportion, it can also realize closed-loop automatic control based on a given parameter signal, and communicate with the host computer. The advantages of integrated dosing device are as follows:
Splitting dosing device is used in some special conditions, such as large dosage amount, special dosing medium, at this time, it is not convenient to integrate the solution box with the dosing pump. If the customer has a large solution tank, the dosing pump block shall be mounted separately from the solution tank, then connect its inlet with the outlet of solution tank by pipe. This device is called splitting dosing device. The solution tank can be a large PE cans, stainless steel cans or cement ponds etc. While the dosing pump block is decided by dosing point number, generally the single-pump type, multi-pump type. Pipeline is fixed by a bracket, with small occupation and reasonable structure. Dosing pump block base is made of high intensive channel. Pipeline is fixed by a bracket, with small occupation and reasonable structure.
