无盲肠磁性液位计在球罐区的设计与应用

The Design and Application of No Cecum Magnetic Level Gauge in the Spherical Tank Area

磁浮子液位计是根据浮力和磁性耦合原理设计的一种现场显示仪表。目前国内外普遍使用的磁浮子液位计,其下端浮子腔为一盲肠结构。设备盲肠在石油石化系统是一大安全隐患,介质腐蚀物的积聚对该处焊缝产生应力,腐蚀开裂;介质中的水分在该处沉降,冬季有产生冻凝的风险,这些隐患时刻威胁着企业的安全。本文提出了一种新型结构设计方法,它采用了独特的无盲肠结构设计,可以最大限度地减少浮球室内积水,以防止浮球被浮球室内的积水冻住,具有结构简捷、使用安全可靠的优点。彻底克服了老式磁浮子液位计的一些缺点,特别适用于炼油、化工厂球罐装置上的液位测量。

Magnetic float level meter is a field of buoyancy and magnetic coupling principle designed display instrument, magnetic float level widely used in China and abroad, the lower end of the float chamber is a anti-blind spot structure. Equipped with the blind spot structure in the petrochemical system is a serious security risk, corrosion cracking of the weld in the weld is produced by the accumulation of the medium corrosion, moisture in the medium, it is risky by using in the winter. This hidden trouble will be threatening the safety of a enterprises. A new structure which is designed for this matter, it uses a unique no cecum design; water can be reduced at the maximum extent, in order to prevent the floating ball free zed by the indoor water. With a simple structure, it will be more reliable and stable. Completely overcomes the shortcomings of the old magnetic float level gauge. Anti-blind spot structure is especially suitable for oil refining and chemical plant tank device.
