Troubleshooting And Repairing Issues With A Decanter Centrifuge

Posted on

A decanter centrifuge is often considered one of the most essential pieces of equipment used to treat wastewater. The rapid rotation of the horizontal bowl will speed up the gravitational separation of sludge. Internal bearings, piping, belts, fasteners, and lubricants need to be maintained since one or more of these materials could falter and disrupt the spinning process that is performed during each treatment. If a centrifuge is down, a centrifuge machine repair technician will need to fix it.

A Blockage

A decanter centrifuge's interior chamber is placed under constant pressure during the treatment process. Sludge is separated and liquid is funneled through piping. As sludge thickens, it will stick to the interior walls of the bowl. The inlet and release pipe may become clogged if too much of the mixture passes through the equipment or if the sludge has thickened excessively. Inspect both pipes and clean the interior piping, to remove blockages.  

Loose Pieces

Loose fasteners or belts will disrupt the normal spinning process and could affect the consistency of the sludge, since liquid may not be reduced in a consistent manner. With the overuse of internal components, pieces may break off or become tangled. After each treatment process, inspect the condition of the sludge.

Upon releasing the solid waste from the horizontal bowl, inspect the internal bearings, metal fasteners, and belts. Hardware pieces can be replaced with the aid of hand tools and a belt may be able to be repositioned, to remedy an issue. For a broken belt or one that is twisted extensively, contact a repair technician who has experience with the centrifuge model that you own.

A technician will likely assess the equipment onsite and will either repair or replace any internal pieces that are worn out and not operating properly. If you are not familiar with checking or changing the lubricants required to maintain your equipment, request that oil and any other lubricant type is assessed during the service appointment.

Speed Discrepancies

The decanter centrifuge's speed may have been factory set, prior to the purchase of the equipment. If the model that you own contains a speed adjustment function, the speed can be altered and affect the overall treatment process.

Since centrifuges are used in various business sectors, including food, oil, chemical, and mining, some uses for a centrifuge may require the modification of the spinning speed. If your equipment is used solely for treating wastewater, ensure that the operators of the equipment know that the speed adjustment function should not be tampered with.
