Before the operation of reflux pump, we should ensure the normal operation of the equipment. Before starting, we should check the unit thoroughly and carefully, especially for the new equipment or water pump that has not been used for a long time. Before starting, we should pay more attention to check the operation, so as to find problems and deal with them in time. The first thing to see is as follows.
① Check whether the foundation screws and connecting bolts of water pump and power machine are loose or fall off. If any, they should be tightened or supplemented.
② Roll the coupling or pulley, check whether the impeller rotation is sensitive, whether there is abnormal sound in the water pump, and judge whether the steering direction is correct. Regarding the water pump of the new equipment, it is necessary to check its steering direction when it is started for the first time. To see if the steering of the pump is the same as the steering plate arrow on the pump. If not, just exchange any two wiring of the motor. If there is no steering arrow on the pump, the pump case is volute type, which can be judged according to the shape of the pump, that is, the rotation direction of the pump and the direction of the volute from small to large are common; for the pump which is not volute type, it can only be judged from the shape of the blade, that is, the pump should rotate along the bending direction of the blade.
Let's take a look at the characteristics of the reflux pump
1. Small head, large flow, high efficiency;
2. It is designed to prevent blocking and winding, and it is reliable to use;
3. With sealing material, it can operate safely and continuously for more than 10000 hours;
4. Compact structure, convenient installation and maintenance;
5. The main engine adopts stamping structure, small volume, high precision, corrosion resistance and no noise;
6. Set up leakage and motor overload protection alarm devices to ensure the safety and reliability of the product.
The function of the reflux pump is to keep the sewage slurry in the sludge tank in the activated sludge state, so that the concentration of suspended solid MLSS in the aeration tank is relatively stable. Therefore, it is necessary to use the sludge return pump to maintain the uniformity of slurry concentration in the aeration tank. The characteristics of the reflux pump can also be seen that it is an indispensable part of the treatment system.
