One person and one sentence cheer for the postgraduate entrance examination MBR integrated operating procedures.
1. Automatic operation: Turning the switch knob of the equipment to the automatic position is automatic operation.
1. The float switch of the adjustment pool starts when the liquid level is high, and the lifting pump stops when the liquid level is low. When the backwash is running, the lifting pump does not start.
2. When the float level switch of the integrated membrane pool reaches the high liquid level, the suction pump starts and the low liquid level suction pump stops. The automatic operation mode of the suction pump is 10 minutes of operation, 2 minutes of cycle delay. When the backwash pump is running, the suction pump stops, and the suction pump continues to run after the backwash is over.
3. The backwash pump backwashes once every 12 hours for 10 minutes each time. The backwash automatically stops the suction solenoid valve and opens the backwash pump solenoid valve.
4. The reflux pump runs every 2 hours for 5 minutes each time.
5. When there is an emergency failure in each part, press the emergency stop button on the distribution box in time, and the equipment will stop running, check and repair, and then start running.
2. Manual operation: Turning the switch knob of the equipment to the manual position is manual operation.
1. In order to better run the water inlet, it is recommended to use manual operation first, and convert it to automatic operation when the water volume reaches normal operation.
2. The equipment arrives at the scene to connect the pipe fittings and the float level switch of the lifting pump, connect the power supply into the control box and connect it with a three-phase four-wire cable.
3. Start the stand-alone machine to see if the running direction is correct, and the equipment box enters the clean water, 4. Test the run, let the suction pump start, and see the water pool flowing outward, and then hit all the knobs to the automatic position and automatic operation.
3. Time setting.
1. Suction pump: run 20m and stop 2m (automatic delay start and stop) (left run and right stop).
2. Backwash pump: run for 10m and stop for 10h (automatic delay start and stop) (right run and left stop).
3. Reflux pump: run for 5m and stop for 2h (automatic delay start and stop) (left run and right stop).
4. Fan: run 30m and stop 20m (automatic delay start and stop) (left run stop).
5. Representation of time relay letters: minutes: m;Hours: h;：s
