In the daily use of centrifugal pumps, attention should be paid to maintaining the centrifugal pump products to extend their service life and prevent equipment failures.

     The characteristics and scope of application of centrifugal pumps

  Characteristics of centrifugal pumps:

  1. Smooth, flexible, and energy-saving transportation.

  2. Good non blocking ability, able to transport materials containing particles and fibers.

  3. Without stirring, it has good non-destructive properties and can transport mixed substances such as fish, shrimp, and fruits.

  4. Suitable for conveying pulp and cotton pulp with a concentration of 1-12%, it has been widely used abroad.

  5. The pump has a simple structure and is easy to maintain.

  6. Pulleys are used to transmit power, so the technical parameters of pumps vary greatly, and the use of variable frequency motors has a more obvious effect.

  Installation and use of centrifugal pumps:

  Before installing the centrifugal pump equipment, it is necessary to check the foundation according to the equipment foundation diagram and physical objects to confirm that the equipment foundation is correct. The pump body is generally made of stainless steel 304 and stainless steel 316, which is more suitable for applications with certain corrosiveness or for food, aquatic products, and fisheries.

  Scope of application of centrifugal pump:

  In the field of sewage treatment: high concentration untreated sewage and pollutants are discharged, such as large-diameter pumps that have passed the test of conveying plastic woven belts up to 1 meter long;

  River dredging: transporting silt and sand;

  Paper industry: transportation of high concentration pulp;

  Marine fishing: transporting live fish and shrimp;

  Transport bulk vegetables such as potatoes and sugar beets.

  In the daily use of centrifugal pumps, attention should be paid to maintaining the centrifugal pump products to extend their service life and prevent equipment failures. The daily maintenance of centrifugal pumps should include the following points:

  1. Always wipe the liquid, dust, or other dirt on the centrifugal pump unit and pipeline to keep the centrifugal pump clean.

  2. The lubricating grease in the bearings of the centrifugal pump should also be replaced regularly. For example, all horizontal centrifugal pump products are usually equipped with sliding bearings. All centrifugal pump products equipped with sliding bearings should have their lubricating oil replaced after approximately 100 hours of use, and the lubricating oil for rolling bearings should be replaced every 300-500 hours.

  If it is a single-stage single suction centrifugal pump with packing seal, the tightness of the packing should be checked and adjusted at any time.

  4. Regularly inspect and tighten loose bolts and nuts.

  5. Regularly clean the suspended solids in the water tank to keep the inlet water tank of the centrifugal pump clean and prevent debris from blocking the inlet pipe, damaging the impeller or blocking the pump body after being sucked into the pump.
