April 17,2024,in a production workshop of Sichuan Zigong Industrial Pump Co., LTD. , Zigong high-tech Zone industrial Park, a steel plate blank is processed the through the automatic transmission belt into the CNC laser cutting machine to be automatically fine cut; On the other side, workers are using vertical lathes to groove weld key parts of the axial flow pump.
“Now we are making every effort to produce the 1600mm diameter chemical axial flow pump to ensure delivery at the end of June.” Shang Yong said, assistant general manager of the company. He told the reporters that the caliber of this batch of axial flow pumps is currently the largest in China, breaking the monopoly of foreign pump companies in the field of evaporation and crystallization of large caliber axial flow pumps. Shyang yong added that “In the past, many companies would purchase large scale axial flow pumps from Sulzer, now companies prefer to buy our products which are more cost effective, and high quality has been tested through numerous applications ”
Chemical axial flow pump is a kind of axial impeller arranged pump, mainly used to transport alkali, salt and other liquids. In the chemical industry, large caliber and large flow are the embodiment of the gold content of industrial pump technology. Large diameter axial flow pumps can provide a large flow (up to 40000 m³/h), which also means that the load is also hugely large, so the processing and stability of the product are highly significant.
Solve the user “pain point” and promote an innovative breakthrough
“Assembly is the last step.” Shangyong took the reporter to the assembly area. The workers skillfully positioned and fastened the impeller and the main shaft, after a while, a diameter of 1600mm of chemical axial flow pump was presented in front of the reporter.
In 2020, the company independently developed the chemical axial flow pump with the largest diameter of 1600mm in China, which was later identified and awarded as “Sichuan Province Major Technical Equipment”.
Mr Shang explained that the hydraulic efficiency of the axial flow pump can reach 82%, the flow rate can reach 40,000 cubic meters per hour, and the flow rate of the system medium can get a low speed of 2 meters/s to protect the crystals forming in the system of falling film evaporator or multi effect evaporators.
