Analysis of operating points of automatic dosing machine

The automatic dosing machine includes a metering input system, a drug dissolving system, a safety system, and a control system. It has the characteristics of compact structure, conducive to maintenance, low cost, and conducive to transportation.

Frequently asked questions about automatic dosing machine operation

1. The dosing metering pump motor is adjusted according to the frequency converter. If you find that the dosing metering pump cannot operate normally, it may be a frequency converter failure. At this time, you should turn on another one (normally, one for use and one for standby), and solve the problem according to the instructions. calibration.

2. When the material level meter is in use, the material becomes damp and adheres to the material, thus interfering with the use experience on the surface of the material level meter. The dosing equipment should be checked and scrubbed frequently (it is recommended to do this once per trip).

3. It is strictly forbidden for water to seep into the electrical components in the control box. The cabinet door must be locked tightly during normal startup, and it is strictly forbidden to flush the control box with water. Otherwise, the electrical components will be damaged.

4. Because the drug in the automatic dosing machine is highly corrosive, all mechanical parts in contact with the drug should be regularly maintained and replaced regularly.

5. If the wire mesh inside the feeder is damaged, please replace it regularly to prevent large pieces of dry medicine from being thrown into the screw feeder and damaging the screw or drive motor.

6. The two pressure level gauges must be regularly inspected and cleaned of the plastic film in the center of the head every month.

7. Because the medicine is sticky, pay attention to whether the feeding pipe is smooth when blowing, especially the bottom of the hopper and the discharge port.

8. When it is normal, open the end cap at the top of the hopper and there will be downward suction. If there is no suction or reverse wind, it indicates that the feeding pipe is not smooth and needs to be checked in time. (It is recommended that it should be disassembled and checked every 20 hours of dosing operation)

9. There is a heater in the hopper. Normally, the air is blown for a while and the feed pipe is slightly hot. If there is no change, it means that the heater is damaged and needs to be checked and replaced in time.

10. The water inlet valve and the discharge valve are automatic ball valves. If water still flows in or medicine flows out after closing, it indicates that the water inlet valve and the discharge valve are damaged and need to be checked and replaced in time.

11. The dosing metering pump of the automatic dosing machine is strictly prohibited from idling and reverse rotation. Before opening the pump, it is necessary to make sure that the front, rear, left and right valves of the metering pump have been opened, and the medium needs to be injected in advance.
