The pump's operation occupies a dominant position in the luning pipeline. The pump stopped operation due to the high temperature of the end tile, so the oil cannot be sealed, which seriously affects the crude oil supply of the long pipeline. Zoucheng maintenance team immediately began to repair.

After a series of repairs, the pump was reloaded.

The successful overhaul of the bingham pump without the guidance of any foreign experts is the first of its kind in the pipeline company and provides experience for future such repairs.
