Overview
CHK type single-stage single-suction suspension back-type chemical centrifugal pump is based on the IH series pump.Refer to the latest foreign design improvements, and its rated performance and installation dimensions in line with IS0285 accurate manufacturing conditions in line with IS05199 standards ? The main For chemical processes containing solid content of less than 50% of the slurry transmission.
Compared with the old pump, CHK chemical pump structure has the following characteristics:
1 'full-open impeller:
2, shortened the impeller cantilever, Jie Jie rough shaft diameter;
3, unsymmetrical soft supplier volute, pump shell Mouth ring;
4, impeller nut and impeller made of one;
5, equipped with advanced foreign double-sided mechanical seal or packing seal similar to the new seal.
The above structure by the dry has the following advantages:
1, can transport high viscosity or solid medium, then pump efficiency than IH pump high:
2, non-symmetrical cross-section volute to reduce the fluid impact loss, shortening the pump housing Size:
3, heap and shaft strength, reducing the rotor deflection.So stable operation, long sealing life;
4, the impeller nut and the impeller made of one. Change the pump inlet conditions, improve the pump anti-cavitation performance;
5, advanced shaft seal formation, so that the sealing effect is better, reducing the pump's diarrhea;
6, the pump casing and impeller can be disassembled to regulate the clearance of the chestnut, reducing the maintenance time and saving the maintenance cost.
