Reutilization of evaporation condensate water and Prevention of cavitation in pump;

Centrifugal Pump Cavitation and Its Prevention;

Application of epoxy resin composite material to the cavitation erosion mending;

Analysis on the cavitation erosion of regulating valve and control measures;

Hardness and resistance to cavitation erosion of Fe-Cr-based HVOF-sprayed coating

On the basis of preventing vapor corrosion and using the basic principle of calculating the physical volume,it is presented that the two methods of calculating the installing height by permissible vacuum suction height HS or net pump suction head Δh are corrected and their results are absolutely consistent.

Steam Corrosion Cause of a Circulating Water Pump and Its Application;

Associated with the steam corrosion of Hebei some certain power plant circulating water pump,after analyzed the main reasons of circulating water pump steam corrosion,brought forwards the effective measures of this problem,to offer the basis of economic safe operation of the power plant.

The reasons of air entering pump have been detailed analyzed for its sudden abnormity and inspection based on the comparison of two accidents: steam corrosion against the pump and air entering pump and combined with the special accident example of the condensate pump.
