High temperature pump routine maintenance and operation methods: First, due to a sudden power outage, resulting in system pressure fluctuations, the emergence of negative pressure system, dissolved in the liquid bubbles in the gas escaped in the high temperature pump or pipe. The treatment is to purge the gas. Second, the high pressure liquid column due to a sudden power outage, the impact of the gear pump outlet check valve plate. Treatment method is unreasonable high-temperature pump discharge system piping, piping accessories to transform the layout. Third, the export pipeline valve shut down too fast. The method is to slowly close the valve. Fourth, the transmission medium to the high temperature oil pump cover and bearing the heat from the high temperature gear pump cover and bearing surface cooling, so that the bearing temperature to adapt to the shaft sealing performance temperature. Therefore, the choice of high-temperature oil pump installation location, make high-temperature oil pump cover and bearing seat of the heat to facilitate diffusion, does not appear any heat storage. Five, shut down: cut off the power. The inner liquid is emptied, cleaned and the gear should be rotated 180 degrees on a regular basis to prevent shaft deformation until the high-temperature oil pump is completely cooled.
