Construction:
Type D\DG, DY\DF\DM pumps are horizontally installation. The direction of inlet and outlet of Type DG, DY\DF is vertical upward except type D pump with horizontal inlet. Type DY1\2\3DF can be also with horizontal inlet and outlet.
The axial thrust gets balanced with the help of balance disk. Type D, DG, DY, DF3_40 pumps get the balanced with the help of Symmetrically construction the shaft seal usually uses packing seal, according to customers' requirements, mechanical seal is used, too. Type Df85_67pumps use sliding bearings which get lubricated with dilute--oil.
The others use rolling bearings which get lubricated with grease except type DF155-67 pump with dilute oil. Materials of tolerance parts: Type D, DG pump are made of cast iron, the shaft is 45# steel.
Type DY: The materials are divided into three types:
1_cast iron(the temperature in operation is 20--150 deg C)
2_cast steel (the temperature in opera |
