Centrifugal pump assembly should pay attention to the matter
1. Pump rotor and volute concentricity. Concentricity of the pump rotor and the volute, determined entirely by the accuracy of machining parts, the pump rotor and volute are required to be concentric, the purpose of which is to avoid the friction of moving parts during operation;
2. Pump impeller runner centerline and volute flow centerline deviation. The lower the impeller runner centerline deviates from the pump housing runner centerline, the higher the pump efficiency. The deviation between the two flow channels should generally not exceed 0.5mm.
3 the bolt tension is appropriate.
4. Pump internal clearance is exceeded, a variety of pump data requirements.
5. Mechanical seal compression is to meet the requirements.
6. For high-pressure pump housing hydrostatic test if necessary.
