What are the steps of using portable sanitary centrifugal pump?

According to the common single-stage centrifugal pump's shortcomings of large flow and low head, it is specially designed as a portable sanitary centrifugal pump with low flow and high head. Its special impeller structure enables the pump to reach high head at low flow. The centrifugal pump has the advantages of high efficiency, energy saving, sanitation, no dead ends, and easy cleaning.

What are the preparations before using portable sanitary centrifugal pump?

1. Whether the name, model, main performance and quantity of the lubricating oil meet the requirements of portable sanitary centrifugal pump;

2. Whether the bearing lubrication system, sealing system and cooling system of the portable sanitary centrifugal pump are intact, and whether the oil and water channels of the bearing are unblocked;

3. Rotate the rotor of the pump for 1 to 2 revolutions, and check whether there is friction or jamming of the rotor;

4. Whether there is any debris that hinders rotation near the coupling or belt guards, etc.;

5. Whether the foundation bolts of portable sanitary centrifugal pump, bearing seat, and motor are loose;

6. The valves or attachments of the portable sanitary centrifugal pump working system should be in the position with the least load when the pump is running, and the outlet regulating valve should be closed.

If the portable sanitary centrifugal pump generates vibration, what is the reason?

1. The rotor of the portable sanitary centrifugal pump is unbalanced and misaligned. This problem accounts for a large proportion of the vibration problems of portable sanitary centrifugal pump, which is about 80%. The factors that cause the unbalance of the portable sanitary centrifugal pump rotor: uneven material blocking, unqualified parts structure, resulting in the rotor mass center line and the shaft center line do not coincide, resulting in an imbalance formed by eccentric data. The rotor imbalance correction of the portable sanitary centrifugal pump can be divided into two. Static balance and dynamic balance: generally also called single-sided balance and double-sided balance. The difference is: single-sided balancing is performed on one calibration surface, while double-sided balancing is performed on two calibration surfaces.

2. Installation reason: the foundation bolts are loose and the level of calibration is not well adjusted. Before the portable sanitary centrifugal pump works, check whether the foundation bolts are loose and whether the centrifugal pump is installed horizontally. These will also cause the portable sanitary centrifugal pump to vibrate when it is working.

How to save the portable sanitary centrifugal pump after use?

①The un-installed portable sanitary centrifugal pump should be coated with a suitable anti-rust agent on the unpainted surface. Bearings lubricated with oil should be filled with proper oil, bearings lubricated with grease should only be filled with one kind of lubrication Grease, do not use mixed grease.

②Rinse the liquid in the portable sanitary centrifugal pump within a short time after use, the suction pipeline, discharge pipeline, pump casing and impeller, and drain the flushing liquid in the pump casing, suction pipeline and discharge pipeline.

③Drain the oil in the bearing box, add clean oil, thoroughly clean the grease and then fill with new grease.

④ Seal the suction port and discharge port of the portable sanitary centrifugal pump, store the pump in a clean and dry place, protect the motor windings from moisture, and spray the inside of the pump housing with anti-rust and anti-corrosion liquid.

⑤The pump shaft of the portable sanitary centrifugal pump rotates once a month to avoid freezing and lubricate the bearings.
