summary:
The CHK single-stage single suction cantilever chemical centrifugal pump is based on the IH series pump and improved with reference to foreign designs. Its rated performance and installation dimensions comply with the ISO2858 standard, and its manufacturing technical conditions comply with the ISO 5199 standard. It is mainly suitable for transporting slurries with a solid content of less than 50% in chemical processes.
Compared with IH pumps, the structure of CHK chemical pumps has the following characteristics:
1. Fully open impeller;
2. Shortened the cantilever of the impeller and increased the diameter of the shaft;
3. Non symmetrical cross-section snail shells and pump casings without mouth rings;
4. The impeller nut and impeller are made into a body;
5. Equipped with a new type of seal similar to advanced foreign double end mechanical seals or packing seals.
Due to the above structure, the pump has the following advantages:
1. It can transport high viscosity or solid containing media, and the efficiency of the pump is higher than that of the IH pump;
2. The asymmetric cross-section volute reduces the impact loss of fluid and shortens the size of the pump casing;
3. Increasing the strength of the shaft reduces the deflection of the rotor, resulting in stable operation and long sealing life;
4. The impeller nut is integrated with the impeller to improve the inlet conditions of the pump and enhance its anti cavitation performance;
5. Advanced shaft seal form ensures better sealing effect and reduces pump leakage;
6. The clearance of the pump can be adjusted without disassembling the pump casing and impeller, reducing maintenance time and saving maintenance costs.
