The jet condenser pump coupled with both air and indirect water cooling systems was successfully used on top of vacuum tower in place of the conventional barometric-jet condenser. The average vacuity was maintained at 700 mm Hg or 696 mmHg under high throughput(above 9258 T/D). The energy consumption was reduced by 1.188 MM kcal/hr. The operating cost was reduced significantly although the initial investment was higher than that of the conventional system. The pay-off time is less than 3 years.

为了扩大空冷技术的应用,我厂把原减压塔顶及抽空系统由混合型流程改造成湿式空冷间冷型流程。改造后,减压塔顶真空度全年平均为700毫米汞柱,在高负荷(9258吨/日)处理量下,真空度平均为696毫米汞柱。能耗减少118.8万千卡/时。一次投资设备费用,空冷比水冷多用146.38万元,但空冷每年可节约操作费用48万元,3年时间可全部收回其投资。

After briefly explaining the work of the drilling pump, we made an analysis of the properties, mechanism and the major influencing factors of the seal failure of drilling pumps. In order to prevent the seal from failing we suggested improving the lubricity of the drilling fluid, perfecting the cleaning system, controlling the clearance between the piston and the liner and taking some preventive measures.
