关于蓄能器中管式液面指示器的滞后问题

根据蓄能器液面与液面指示器液面的相互关系及流量的方向不同,蓄能器与液面指示器之间的流动可分成四种类型。本文导出了这四种流动类型下大罐与指示器间液面差随时间的变化以及该液面差的极大值的计算公式,并以某厂水压机蓄能器为例说明指示器液面滞后的计算方法。

On the Hysteresis in a Tubular Level Meter of Reservoir

According to the relation between the fluid level in a level meter and that in reservoir and the direction of flow, the fluid flow from reservoir to level meter can be divided into four typical cases. The time-dependent variation of the level difference detween reservoir and level meter is thus studied in all the four cases with a calculating formula for the maximum value of level difference derived. As an instance, a reservoir or accumulator for hydraulic press is included to explain the computing method of the hysteresis in level meter.
