Clean / check the heating hopper and venturi ejector

Cleaning / checking the rotary level gauge

per month

Clean all motor fan guards clean / check water circuit control lubrication dosing screw shaft drive bearings every 2500 hours - check the operation of the transfer valve and water control electric ball valve

lubricating

Motor use and maintenance

1. Motor use and maintenance

See the motor's operating and maintenance instructions or operating instructions.

2. Screw pump use and maintenance

Operational precautions

1. The dosing metering pump motor is controlled by the inverter, and it is found that the dosing metering pump can not work normally. It may be the inverter fault. At this time, another unit (normally used and one standby) should be activated, and the fault should be reset according to the manual.

2. The level gauge of the material during use wet adhesion material, thereby affecting the surface of the material using the effect of the switch should always check the dosing device and the wiper (recommended once per shift).

3. The control cabinet of electrical components prohibition water, should be used normally closed door, rinsed with water to eliminate the control cabinet. Otherwise the electrical components will be damaged.

4. Due to the strong corrosiveness of the chemicals, the mechanical parts in contact with the chemicals should be inspected regularly and replaced in time.

5. If the internal screen of the feeder is damaged, please replace it in time to avoid the bulk of the dry medicine from being fed into the screw feeder, damage the screw or drive the motor.

6. Two pressure level gauges should check and clean the film on the center of the head every other month.

7. Because of the sticky agent has, in the feed conduit should be noted that blowing is smooth, and particularly below the hopper discharge opening two.

8. When normal, open the end cap of the upper hopper and have downward suction. If there is no suction or anti-wind, the feeding pipeline is not smooth, so check it in time. (It is recommended to open and inspect every 20 hours of dosing )

9. There is a heater in the hopper. When the air is supplied normally for a period of time, the feeding tube is slightly hot. If there is no change, the heater is damaged and should be checked and replaced in time.

10. The inlet valve and the discharge valve are automatic ball valves. After the shutdown, there is still water flowing in or the medicament flows out, indicating that the inlet valve and the discharge valve are damaged, and should be checked and replaced in time.

11. Dosing and metering pumps are forbidden to idling and reversing. Before opening the pump, it must be determined that the valves before and after the metering pump have been opened, and the medium needs to be injected beforehand.
