1.Check the foundation precausions, should meet the requirements; check the anchor bolts should be tightened in place; the two are looking for precision to meet the requirements.
2.The motor of the steering, should be consistent with the direction of rotation of the pump, the motor insulation should be consistent with the provisions of.
3.Electrical instruments and pump pressure gauge, vacuum gauge, etc. should be sensitive and accurate, the valve should be flexible and reliable.
4.Cooling, heat preservation, washing, filtration, lubrication, liquid sealing systems and processes, should be connected to the correct, no leakage phenomenon; pipeline should be washed clean, ensure smooth.
5.Conveying liquid temperature is higher than 120 degrees of centrifugal pump, to ensure reliable lubrication of bearings, bearing parts should be cooled.
6.The mechanical seal should be cooling, washing, crystallization of the material conveying pump, start again before the crystal will seal site clean, so as not to affect the effect or damage to the sealing surface of the seal assembly; the mechanical seal should comply with the requirements.
7.The packing seal of the pump, the tightness of packing should be appropriate; the cooling liquid seal ring should be aligned with cooling nozzle, cooling liquid should be smooth.
8.The lubricating parts, should be added to meet the requirements of lubricant.
9.The inlet of the pump must be device filter, the effective area of the filter screen should not be less than 2 times the cross-sectional area of the pump inlet.
10.The first single from the coupling, test drive, motor driving tests should more than 2h.
