本文介绍一种新研制的聚酯网透水率测定仪。聚酯网是当代造纸业中取代铜网的一项最新措施,聚酯网的主要技术指标之一就是透水率。我们抛弃了国外采用的单级稳压器方案,采用了两级稳压的恒压器,辅以电接触式传感器,在智能化逻辑电路控制下,实现了自动测量、自动计时,数字显示,事故报警。经检定,该仪器测量精度优于±1％。 This article introduces a newly developed polyester mesh water permeability tester. Polyester net is the latest measure to replace the copper net in the contemporary papermaking industry. One of the main technical indexes of the polyester net is the water permeability. We abandoned the single-stage regulator scheme adopted abroad and adopted a two-stage constant voltage regulator with an electric contact sensor. Under the control of the intelligent logic circuit, we realized automatic measurement, automatic timing, digital display, Accident alarm. The test, the instrument measurement accuracy better than ± 1%.
