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.
