Summary:
CHK type single-stage single suction cantilever Chemical centrifugal pump is based on IH series pump, with reference to foreign latest design, which conforms to the standard ISO2858 being adopted, the rated performance and installation dimension lSO5199 standard manufacturing technology conditions, mainly is suitable for the Chemical process of slurry solid content less than 50%.
Compared with the IH pump, CHKChemical pump structure has the following features:
1. All the open impeller;
2. Shortened the impeller of the cantilever, bold the diameter of the shaft;
3. The asymmetrical cross section of the volute, pump shell without mouth ring;
4. The impeller nut and impeller make it - body;
5. Equipped with with foreign advanced double mechanical seal or packing seal similar to the new type seal.
Due to the above structure make the pump has the following advantages:
1. Can transport high viscosity or containing solid medium, the pump's efficiency is relatively high IH pump;
2. The asymmetric cross-section volute to reduce the impact of the fluid loss, shorten the pump casing size;
3. Increase the axial intensity and reduce the deflection of the rotor, thus running stable, long seal life;
4. The impeller nut and impeller make it - body, improve the pump inlet conditions, to improve pump cavitation resistance;
5. Advanced form of shaft seal, get better sealing effect, reduce the leakage of pump;
6. Can not remove the pump casing and impeller under the condition of adjusting the clearance between the pump and reducing the maintenance time, save the maintenance cost.
