Recently, Siping Haohua’s pump renovation project received the Jilin Workers’ Excellent Technology Innovation award. Its technology enhances the abrasive resistance of brine pump casing and vane wheels, helping pumps run longer and reducing maintenance.
The company has conducted renovations and has strived to make technical breakthroughs since the beginning of 2012 to improve steady equipment operation. Made of titanium, the three pressure pumps in the brine section suffered severe wear and tear due to crude salt impurities, such as coke and coal, which easily caused brine leakage. Maintenance had to be conducted every six months, costing more than 9,000 yuan ($1,466) each time. In addition, the pump cases and vane wheels had to be returned to producers for repair, prolonging the overhaul cycle. Therefore, technical personnel and employees studied together and decided to use high speed steel for pump cases and vane wheels. After repetitive testing and calculations, the renovated pumps were installed and run. So far there have been no compromise in function and no erosions.
The renovation project has saved 180,000 yuan in costs because high-speed steel is cheaper than titanium. The maintenance fees will be brought down by 54,000 yuan annually. In addition, with no brine leakages, raw materials costs can be cut by more than 230,000 yuan a year.
