Quality Requirements

1. This equipment must meet the demands of technical data and drawing . When ensure the operation performance ,the supplier must ensure the maintenance cost is low and economic.

2. During rotating , the fabricated screw shaft and screw flightsmust have strong strength and stiffness.There must ensure there is no deformation during conveyed tetrahydric alcohol powder.

3. For the bearing house, the sealing is very important . There must be no powder leakage and no lubricating grease .

4. There must ensure the reasonable clearance between shell and screw shaft ,so as to make the equipment rotate flexible.

5. The shaft’s bearing circular run out must less than 0.25mm, so as to keep the shaft is straight.

6. The outer surface must be evenly ,no color difference

7. The nameplate is made of 304.

8. Welding is by argon arc welding, there shall be no undercuts, pores, cracks on welding technology.
