Chemical pump assembly should pay attention to what matters:
1.Pump shaft bending, deformation.
2.Whether the rotor balance is in line with the standard.
3.The gap between the impeller and the pump casing.
4.Mechanical seal buffer compensation mechanism to achieve the required amount of compression.
5.Pump rotor and the spiral case of the concentric.
6.Pump impeller runner center line and the center line of the spiral case flow channel is right.
7.Gap adjustment between bearing and end cover.
8.The adjustment of the clearance of the sealing parts.
9.Transmission system motor and variable (increase or decrease) the assembly of the speed device is in line with the standard.
10.Coupling of the coaxial to find the right.
11.Ring clearance is consistent with the standard.
12.Chemical pump each part is suitable for the connection of the bolt.
