deep well anode
相关语句
  深井阳极
     After the cathodic protection measures ie the deep well anode bed plus impressed current were adopted for the underground pipeline network of Eureka unit in the refinery of Yangtz Petrochemical Company, the protection voltage was - 0.852 - -2.0. This reduced the leakage by 63.6% compared with that without the cathodic protection and the pipeline operation life could be extended by 20 to 25 years.
     扬子石化公司炼油厂尤里卡装置地下管网采用以深井阳极地床外加电流为主、牺牲阳极为辅的阴极保护措施后,保护电位处于-0.852~-2.0V范围,使泄漏率比保护前降低了63.6%,可使管道寿命延长20~25年。

Deep well anode grounding beds are often prefered because of their effectiveness if there is shielding, disturances or a case in which regional pretection is considered necessary for buried pipe network.But its application is limited by complex engineering and expensive in construction. Here is Presented a simple, effective favricating way of construction, by which it is only 80% more expensive in cost than shallow buried graphite anode grounding bed to build up a 20m deep similar one.

当存在有屏蔽、干扰或者对埋地管网要实施区域性保护时,选用深井阳极地床是一种有效的措施。但由于其施工技术复杂、造价昂贵,限制了其使用范围。本文介绍一种施工简便、效果好、造价仅比浅埋式石墨阳极地床贵80%的20米井深石墨阳极地床的组装式施工技术。

Some problems may occur when applying conventional CP system to a oil pump station which is characterized by limited working area, concentrated production facilities and related pipings, numerous branchings, and complex piping systems. It is the distinguishing feature of local CP system that the subject to be protected is a complex of metallic structures located in a limited area. Based on the practice of CP in a localized pump station,it is pointed out that (1)primary subject for CP shall be the bottom plates...

Some problems may occur when applying conventional CP system to a oil pump station which is characterized by limited working area, concentrated production facilities and related pipings, numerous branchings, and complex piping systems. It is the distinguishing feature of local CP system that the subject to be protected is a complex of metallic structures located in a limited area. Based on the practice of CP in a localized pump station,it is pointed out that (1)primary subject for CP shall be the bottom plates of oil tank,followed by buried or underground pipeline as well as related facilities; (2)the reasonable range of polarized potential for local CP shall be - 0. 85--1. 20 V;and (3) deep well anode is the preferred choice to other anode bed alternatives for local CP system. With the stray current interference going with application of this technique,highly resistant potentiostat plus zinc alloy anode system is used so as to increase drainage protection and eliminate further unsafe factor to the local CP system.

输油泵站站内区域较小,生产设施及其相连的工艺管网相对集中,分支较多,管网的构成复杂,这些因素给站内采用常规的阴极保护系统带来了一定困难。区域阴极保护的特点就是保护对象为一定区域内金属结构的复合体。通过对站区区域性阴极保护技术课题的现场实施,提出:①阴极保护对象应首先集中在油罐底板,其次是埋地、地沟管道及其相关设备,②站内区域性阴极保护的极化电位在-0.85~-1.20V范围比较恰当合理,③深井阳极是区域性阴极保护系统中阳极地床的首选方案。针对该技术应用中存在的杂散电流干扰问题,采用抗干扰能力强的恒电位仪以及锌合金阳极的联合保护,加强系统的排流能力,使站内补加的区域性阴极保护系统不会构成新的不安全因素。

In this paper,an angle drilled anode bed CP system adopted in large tank at abroad is introduced. With a hole-bored PVC pipe installed in this system,the tank/soil potential can be easily measured. Compared with the anode bed uniformly distributed around tank and the deep well anode bed,the protection current of angle drilled anode are more uniformly distributed,which can provide a better protection to the central bottom plate of tank.

针对大型储罐施加阴极保护后,如何使电流分布均匀,如何测量保护电位等问题,介绍了国外大型储罐安装的斜井阳极阴极保护系统。该系统采用钻孔的PVC塑料管可以方便地测量储罐对地电位,与均布在储罐周围的阳极地床以及深井阳极地床相比,斜井阳极电流分布更为均匀,且能更好地保护罐中心底板。
