1·Because the packings on the second plate were blocked by polymer, water from the reflux pump condensed and entered into the bottom of the tower to cause the cavitation of the pump.

汽油分馏塔第二层塔填料堵塞，全塔气-液传热传质状况恶化，使水降至塔釜引起“暴釜”，最终导致急冷油泵气蚀不上量。

2·High viscosity pump can match the relief valve, when the pump and piping system overpressure, safety valve is opened, the formation of internal reflux, ensure the safety of the system.

高粘度泵可配安全阀，当泵或管路系统超压时，安全阀门打开，形成内部回流，保证系统安全。

3·Prescription proton pump inhibitors are used to treat conditions such as gastroesophageal reflux disease (GERD), stomach and small intestine ulcers, and inflammation of the esophagus.

处方质子泵抑制剂用于治疗的疾病如反流性胃食管疾病(GERD)、胃和小肠溃疡、食道炎症。

4·There may be an exponent relation between deep venous reflux and calf muscular pump function.

深静脉返流与小腿肌泵功能之间存在一种指数关系。

5·Patients with demonstrated reflux by pH study or with reflux symptoms after surgery should be treated long-term with proton pump inhibitors.

患者表现出受pH值与胃食管反流症状的研究或手术后应被视为与质子泵抑制剂的长期逆流。

6·By simulation, the effects of reflux ratio, the area of the preheat-cool exchanger, cool duty of still pot, heat duty of evaporator and the liquid flow recycled by pump on heat sens...

通过模拟计算，研究了回流比、预热冷却器面积、塔釜冷却量、蒸发器加热量以及泵循环流量对热敏精馏过程的影响。
