一、现有浮球阻油器分析 阻油器是用来提高石油储运真空系统的效率、避免溢油事故的重要部件。它的主要作用是“阻油过气”,即阻止油品通过而让气体畅通。一般它使用在两个场合(见图1)。一是把它装在离心泵和真空管之间,作为灌泵时排气或离心泵运转中自动排气,习惯称为“泵用阻油器”。这种阻油器的气流量小,要求可以直观地观察气流情况,允许有少量油品泄流。另一种是所谓“罐用阻油器”,它装在真空罐和真空泵之间。这种阻油器气流量很大,一般炼 First, the existing float oil separator analysis Oil damper is used to improve the efficiency of the oil storage and transportation vacuum system to avoid oil spill an important component. Its main role is to “stop oil over the gas”, that is, to prevent the passage of oil and gas flow. It is generally used on two occasions (see Figure 1). First, it is installed between the centrifugal pump and the vacuum tube, as a pump exhaust or centrifugal pump operation automatically exhaust, used to be called “pump with oil.” The gas flow of this oil damper is small, requiring visual observation of the airflow and allowing a small amount of oil to drain. The other is the so-called “tank oil stopper”, which is installed between the vacuum tank and the vacuum pump. This oil damper gas flow is large, the general refining
