Daily Management Of Centrifuges

Daily Management Of Centrifuges

Decanter centrifuge is an industrial machine. Not only should pay attention to safety in use, but also pay attention to the maintenance and management of the machine.

In all walks of life, it is also very important to choose a suitable model.

Take Various Measures To Reduce The Vibration Of Centrifuge

At the end of the centrifuge run every time should be to strengthen the water flushing of centrifuge drum, according to our experience, if the drum washing is not complete, will cause the sludge during suspended centrifuge in the adhesive on the drum, then, when starting up, drum will be due to the uneven force, causing the destruction of the dynamic balance, leading to strong vibrating centrifuge; In addition, when reinstalling the liquid level baffles after cleaning the supernatant flowback pipe each time, it should be noted that all the liquid level baffles are at the same height, and the tolerance of the height of the liquid level baffles should be -0.25mm-0.25mm, otherwise it will lead to uneven force on the centrifuge and violent vibration.

Reduce Supernatant Solid Content, Reduce Equipment Wear

We found in the production run, if the sludge contains a lot of sediment, and in the operation of the centrifuge upper clear liquid solid content is higher, if long-term operation in this state, as you can see from the above principle diagram of the centrifuge, because of the supernatant liquid was thrown from the reflux pipe, has the very high velocity, this will cause the centrifuge bolt and counter weight of wear and tear, Therefore, strict management and careful operation in production and operation to reduce the solid content of supernatant liquid are of great significance to reduce the wear of centrifuges.

Clean The Supernatant Reflux Line Regularly

In the production and operation, if the supernatant of sludge dehydration contains large amount of solid, it is easy to cause the blockage of the supernatant backflow pipe, which will lead to the decrease of the solid content of dehydrated sludge, centrifuge will also produce vibration due to uneven force, so it must be cleaned periodically on the supernatant backflow pipe according to the actual operation situation. Supply equipment came with a root and the supernatant reflux pipe of the same length of water pipe, can be inserted into the supernatant reflux pipe to wash, but with this kind of backwash water pipe can't rinse thoroughly, can lead to supernatant reflux pipe wall on the flush is not thoroughly stained with mud, the centrifuge vibration in running, we will transform to flush the tube with brush, This allows for a more thorough flushing of the supernatant reflux line. The cleaning cycle of the supernatant reflux pipe is generally between 50-100 hours, depending on the solid content of the supernatant during the centrifuge operation.

Regular Cleaning Into The Mud Screw Pump

Urban sewage treatment plants in the settling basin for the first time the sludge contains a lot of hair, is general machinery grille is difficult to remove material, in the production of screw pump, it is easy to plug in the operation of the sludge should be cleaned up on a regular basis, avoid a centrifuge is running, because of the sludge of the screw pump congestion, caused by forced outage events, general cleaning cycle between 50-100 hours.

Maintenance Of Flocculant Automatic Dispensing Device

Because the aqueous solution of polyacrylamide is in a sticky state and its solubility is relatively poor, it is easy to cause PAM, caking and fouling in the pipeline of the flocculant automatic dosing device and on the stirrer. For example, we found that after long-term operation PAM will accumulate on the static mixer and agglomerate on the sensor (probe) of the static pressure level gauge, resulting in inaccurate indication results and malfunction of the equipment. Therefore, during the idle period of the equipment, the flocculant should be cleaned regularly. The agglomeration and siltation caused by PAM in the dosing device is necessary to keep the equipment in good operating condition.
