第一，浮盘一旦触底，且物料液位高于浮盘高度，这对油品蒸发消耗影响极大。
第二，轻易对浮盘形成侵害。
第三，浮盘触底后，呼吸阀会翻开，物料的挥发量就会增大，对易挥发的物料会形成必定量的伤害。
第四，可能会呈现浮盘支柱将罐底钢板砸渗漏的事变。
第五，假如气温，液位稳定很大，会招致油罐压力很不稳定，形成隐患或许事变。

First, once the float touches the bottom, and the material level is higher than the height of the float, this has a great impact on the evaporation consumption of oil.
Second, it is easy to infringe on the float.
Third, after the floating disk touches the bottom, the breathing valve will open, the volatilisation of the material will increase, and the volatile material will form a certain amount of damage.
Fourth, there may be a case of floating plate support to the bottom of the tank steel plate leakage.
Fifth, if the temperature, liquid level stability is very large, it will incur tank pressure is very unstable, forming hidden dangers may occur.
