The basic way to prolong the service life of fountain pump

1, fountain pumps should be preceded by opening the inlet valve and valve sealing liquid pump, check whether the pump body has been filled with liquid;

Lockout procedures: slowly off the pump outlet valve; motor pressing the button stops the motor; pump inlet valve to close and seal valve.

Fountain pump periodic inspection. Centrifugal pump cycle can be divided into the following three general inspection and increased shaft deflection, and even the shaft fatigue fracture. If you can not increase the traffic on the production, you can consider increasing the reflux from the process piping, in order to achieve the purpose of regulating traffic.

Fountain pump monthly checks. Without disassembling the outer parts of the equipment for cleaning and minor repairs, including temperature checks on aspects of bearing, shaft seal leakage causes and motor insulation and the like.

2. Slowly open the outlet valve of the pump flow and pressure indication by the need to adjust the outlet valve opening. Is normal, the various parts of the unit to check for leaks; check the degree of packing compression, usually padding should be a small amount of leakage (no more than 10 drops per minute to 20 drops); mechanical seal leakage should not be greater than 10ml / h (per minute about 3 drops); rolling bearing temperature should not exceed 75 ℃; sliding bearing temperature should not exceed 70 ℃; any abnormal sound, abnormal vibration, reducing the amount of water situation.

Accurate selection of fountain pump flow, head, ensures fountain pump in the course in the best performance state. If the fountain pump operation at low flow conditions in the fountain pump can cause circulation whirlpool, and a radial force, the impeller in an unbalanced state, to increase the load bearing, causing damage to seals and bearings, low-flow but also serious the fluid temperature, turbine and centrifugal pump casing damage routine inspection.

Use of checks, including: check a variety of instrumentation is working properly, stable, the current should not exceed the rated value. Pressure gauge pointer should be in the range of design; check the pump out the water and the correct use of the periodic examination is the fundamental way to extend the life of the fountain, check the sliding parts wear, corrosion damage inspection of the components contact with the liquid and the like.

Fountain Pump regular maintenance. Including the replacement of the shaft seal lubricant, check the pump and motor on the situation, check the bushings wear, check the coupling rubber ring damage, cleaning mechanical seals, coolant filter and.

3, confirming the pump body has been filled with liquid and sealed fluid flow is normal, start fountain pump;

Proper startup and shutdown procedures, the operating procedures.
