Compared with IH pumps, HJ alkali pump structure has the following characteristics:
1. The cantilever of the impeller is shortened and the diameter of the shaft is thickened;
2. Volute casings and pump casings with asymmetric cross-sections have no orifice rings;
3. Use three imported bearings;
4. Equipped with a new type of seal similar to foreign advanced single and double end face mechanical seals or packing seals;
5. The machine is equipped with a cooling water device, which improves the service life of the mechanical seal;
Due to the above structure, the pump has the following advantages:
1. It can transport high viscosity or solid-containing media. At this time, the efficiency of the pump is higher than that of the IH pump;
2. The asymmetric cross-section volute reduces the impact loss of the fluid and shortens the size of the pump casing;
3. Increase the strength of the shaft and reduce the deflection of the rotor, resulting in stable operation and long seal life;
4. Improve the inlet conditions of the pump and improve the anti-cavitation performance of the pump;
5. The advanced shaft seal form makes the sealing effect better and reduces the leakage of the pump;
use:
Alkali production industry, steel industry, acid production industry, petrochemical industry, synthetic fiber and plastic industry, paper industry, fertilizer industry, pharmaceutical industry, environmental protection.
Material:
For parts in contact with the medium, commonly used materials are as follows: cast iron, cast steel, 2Cr13, 0Cr18Ni9, 1Cr18Ni9, 0Cr18Ni9Ti, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, 40Cr, 1Cr18Ni12Mo2Ti, Ti (titanium), Monelle, 00Cr17Ni12Mo2Ti, Heshi B alloy, 0Cr25Ni20, F5 series alloy, 20 alloy steel, 0Cr25Ni6Mo3Cu2Mn2Si.Shaft seal: mechanical seal, dynamic seal and packing seal are used, and the user can choose at will.
