第一，浮盤(pán)一旦觸底，且物料液位高于浮盤(pán)高度，這對(duì)油品蒸發(fā)消耗影響極大。
第二，輕易對(duì)浮盤(pán)形成侵害。
第三，浮盤(pán)觸底后，呼吸閥會(huì)翻開(kāi)，物料的揮發(fā)量就會(huì)增大，對(duì)易揮發(fā)的物料會(huì)形成必定量的傷害。
第四，可能會(huì)呈現(xiàn)浮盤(pán)支柱將罐底鋼板砸滲漏的事變。
第五，假如氣溫，液位穩(wěn)定很大，會(huì)招致油罐壓力很不穩(wěn)定，形成隱患或許事變。

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.
