A、主要由外简、沿外筒上下运动的活塞、底板及顶板组成。It mainly consists of a simplified piston, a bottom plate and a top plate moving up and down along the outer cylinder.
B、燃气储存在活塞以下部分,随活塞上下移动增减其储气量。The gas is stored below the piston and increases or decreases as the piston moves up and down.
C、不像湿式罐那样设有水封,可大大减少罐的基础荷载,对于大容积贮气罐的建造非常有利。Unlike the wet tank with water seal, can greatly reduce the tank foundation load, for large volume tank construction is very beneficial.
D、干式贮气罐的最大问题是密封问题,即如何防止在固定的外筒与上下活动的活塞之间产生漏气。The biggest problem with dry storage tanks is the sealing problem, which is how to prevent air leakage between the fixed outer cylinder and the moving piston.
E、根据密封方法不同,目前实际采用的有三种罐型。 According to the different sealing methods, there are three kinds of tank.
F、缺点:没有水槽,因而产生复杂而不易解决的密封问题,即如何防止活塞与外筒之间的漏气。需提高对罐体及活塞等部件施工质量的要求。Disadvantages: no sink, resulting in a complex and unsolvable problem of sealing, that is, how to prevent leakage between the piston and the outer cylinder. The construction quality of tank and piston should be improved.
G、优点: 没有水封,大大减少了罐的基础荷载,有利于建造大型储气罐,又节约金属。Advantages: no water seal, greatly reduce the tank base load, conducive to the construction of large gas storage tank, and save metal.
