摘要
针对低温甲醇洗冷态泵机封、泵轴容易结冰,造成抱轴,不能备用,影响生产的问题,设计一种冷态泵机封防冻装置,实现机泵设备防冻及正常备用。
The cold pump mechanical seal and shaft in the rectisol unit are easy to freeze ,then lead to bearing locking ,and can not to be spare ,so the production is influenced. To solve the problem an antifreezing device of the cold pump mechanical seal is designed to achieve the pump equipment antifreezing and normal spare.
