HSN three screw pump HSN model description

Description of main parameters, separation number and auxiliary parameters of pump model, industry code, series code, installation method, screw parameter code, bearing lubrication form, relative position of inlet and outlet, special requirements, working speed, working pressure specification code, spiral angle of main rod spiral direction, CHSN H660R46WZT1/2P251. Industry code: No code means normal use, C means ship-specific, D means power-specific, S means petrochemical-specific, and "special" means professional use products designed and produced according to the special requirements of corresponding industries;

2. Installation mode: H stands for horizontal installation, F stands for bracket installation, S stands for vertical installation, and K stands for immersion installation;

3. Specification code: See the performance parameter table for details;

4. Spinning direction of the main rod: R means that the spiral direction of the main rod is right (normal use), and L means that the spiral direction of the main rod is left;

5. Spiral rising angle: See the performance parameter table for details;

6. Bearing lubrication form: no code means bearing built-in, and W means bearing external;

7. Relative position of entrance and exit: no code means right entry and left exit, z means left entry and right exit, and d means end entry and end exit. The direction standard of the relative position of the inlet and outlet is from the drive (motor) end to the pump direction, and D there is no S and K installation method for the relative position of the inlet and outlet;

8. Special requirements: No code means no special requirements, and T 1, T2, T3…… ..........................................................................................................................................

9. Working speed: No code indicates a 4-stage motor, synchronous speed 1500r/min, 2P indicates a 2-stage motor, synchronous speed 3000r/min, 6P indicates a 6-stage motor, synchronous speed 1000r/min, VF indicates a variable frequency motor, and the speed is adjustable;

10, working pressure: no code means working pressure ≤ 1.0MPa, 25 means working pressure ≤2.5MPa, and 40 means working pressure ≤ 4.0 MPa;

1 1. If the auxiliary parameters are reflected and required in technical documents such as user technical agreements and tenders, they may not be reflected in the model.
