一、修订背景近年来,随着能源需求日益强烈,作为清洁能源的天然气在国内的使用量越来越广泛,加气机产品的需求在增大,国内加气机产业发展也非常迅速。市场上出现很多最大流量超过30kg/min的加气机。这些加气机主要为大型储气装置(如槽车)充装压缩天然气,俗称加气柱。也有的加气机是将大型移动储气装置的天然气转供到固定储气装置中,市场上称为卸气柱。目前这些大流量加气机性能不一,很多加气机缺乏自
First, the revised background In recent years, with the increasing demand for energy, natural gas as a clean energy in the domestic use of more and more widely, the demand for air bearing products is increasing, the domestic air bearing industry is also very rapid development. A lot of aerators with a maximum flow of more than 30 kg / min appear on the market. These filling machines are mainly for large-scale gas storage devices (such as tank cars) filled with compressed natural gas, commonly known as gas column. In some cases, the gas generator supplies the natural gas of a large mobile gas storage unit to a fixed gas storage unit, which is referred to as the unloading column on the market. At present, these large flow aerators vary in performance and many lack of gas aerators
