Pump Testing

Applicable products: Suitable for various industrial and civilian pump products such as centrifugal pumps, reciprocating pumps, gear pumps, screw pumps, vacuum pumps, submersible pumps, chemical pumps, fire pumps, sewage pumps, booster pumps, magnetic pumps, self-priming pumps, etc.

Applicable scenarios: Used for pump factory inspection, type testing, on-site performance acceptance, in-service equipment monitoring, fault diagnosis, maintenance quality assessment, failure analysis, and quality arbitration testing.

Applicable fields: covering pump bodies and supporting components for industries such as water supply and drainage, HVAC, chemical, petroleum, fire protection, mining, power, sewage treatment, shipbuilding, metallurgy, etc.

Hydraulic performance testing: evaluation of flow rate, head, shaft power, efficiency, speed, cavitation allowance, pressure stability, and flow regulation characteristics.

Mechanical operation detection: vibration value, noise value, bearing temperature, motor temperature rise, pump temperature rise, smooth operation, and detection of jamming and abnormal noise.

Sealing performance testing: static sealing, dynamic sealing leakage, pressure resistance test, air tightness test, anti leakage performance test.

Structural and dimensional testing: evaluation of external dimensions, installation dimensions, pump body coaxiality, impeller accuracy, shaft diameter, fit clearance, and form and position tolerances.

Safety performance testing: motor insulation resistance, grounding performance, overload protection, explosion-proof performance, protection level (IP), leakage protection testing.

Reliability and lifespan testing: no-load operation, continuous load operation, durability life test, start stop cycle test, and fault interval time evaluation.

Material and physical and chemical testing: Inspection of pump body, impeller, shaft material composition, hardness, corrosion resistance, wear resistance, and metallographic structure.

Non destructive testing: Ultrasonic testing, magnetic particle testing, and penetrant testing are used to detect defects such as cracks, looseness, and inclusions in components such as pump bodies, impellers, and main shafts.

Supporting performance testing: motor compatibility, coupling alignment, pipeline adaptability, flow and pressure control accuracy, frequency conversion regulation performance evaluation.
