Automatic dosing device for waterworks

Automatic dosing device for waterworksOperation precautions

1. The motor of the dosing metering pump is controlled by a frequency converter. It was found that the dosing metering pump cannot work normally, which may be due to a fault in the frequency converter. At this time, another one should be used (one in use and one as backup), and the fault should be reset according to the instructions.

2. During the use of the level gauge, the material becomes damp and adheres to the material, which in turn affects the effectiveness of use on the surface of the level switch. The dosing device should be checked regularly and wiped (it is recommended to do it once per shift).

3. The electrical components inside the control cabinet are prohibited from entering water. During normal use, the cabinet door should be tightly closed and the control cabinet should not be rinsed with water. Otherwise, it will damage electrical components.

4. Due to the strong corrosiveness of chemicals, all mechanical components in contact with the chemicals should be regularly inspected and replaced in a timely manner.

5. If there is any damage to the internal screen of the feeder, please replace it in a timely manner to avoid large pieces of dry chemicals from entering the screw feeder and damaging the screw or drive motor.

Automatic dosing device for waterworksconfiguration

The dry powder dosing device is a fully automatic continuous configuration and dosing system for powdered (or liquid) polymer flocculants. The dry powder flocculant enters the pre mixer from the screw propeller and is pre mixed with clean water. The moistened material enters the preparation tank for dilution and is prepared according to the required concentration; If it is a liquid flocculant, it is directly added to the preparation tank by a screw pump. During the preparation process, if there is a change in water volume, the flocculant dosing device will automatically follow the change in water flow rate to ensure that the concentration of the prepared solution remains unchanged throughout the entire working process.The complete set of equipment mainly includes a feeding system, a storage tank, a dosing system, a power control system, etc. The dissolution tank is equipped with facilities required for automatic operation, such as level gauges, low level alarms, valves, etc. A magnetic flap level gauge is installed on the outer wall of the barrel to monitor the liquid level in real-time. There is a feeding port and a backup port on the top of the barrel, and a discharge port, a discharge port, an overflow port, a level gauge interface, and corresponding matching valves are provided on the side of the barrel. When the liquid level in the bucket is lower than the set low liquid level value, the alarm system will automatically activate and the dosing pump will pause. The application of automatic dosing devices is becoming increasingly widespread. The automatic dosing device relies on hydraulic natural drive and is directly installed on the water line, unaffected by water pressure and flow. It automatically dilutes antibiotics, vitamins, acidifiers, vaccines, etc. in proportion, which can cause great irritation to the skin. Before use, a large amount of base oil must be diluted to reduce skin sensitivity. May cause skin sensitivity and should be kept out of reach of children.
