| Abstract: | Several shaft-breaking incidents molten urea in a melamine plant of high-pressure occurred during the nmning of booster pump for process has caused many unscheduled plant shutdowns. The cause for pump shaft-breaking was found based on the special pump structure and medium and also the counter-measures and avoiding method, corresponding measures are taken to re-construct and to improve the process and a good result is obtained. |
