NXQ(A)型囊式蓄能器是一种较新的多功能液压元件。本文主要介绍它作为液压系统的贮蓄能量和吸收压力脉动元件时的正确使用。NXQ(A)型囊式蓄能器(以下简称NXQ 型蓄能器),是一种充气隔离式蓄能器。自1980年通过系列鉴定以来,不仅产量有了大幅度提高,而且得到了广泛的应用。目前,这个系列的蓄能器,其公称容积有0.6L(通径20mm),1.6L、2.5L、4L、6.3L(通径32mm),10L、16L、25L、40L(通径50mm),工作压力为10MPa、20MPa、31.5MPa。NXQ 型蓄能器具有结构简单、胶囊气密性好、动态响应快、安装与使用方便等特点。在液压系统中,它的主要功用是贮蓄能量、吸收脉动压力和冲击压力。而它的正确使用,对提高液压系统的节能效益和品质指标、提高执行机构的工作精度、延长系统和元件的寿命、避免或减少因压力脉动或压力冲击引起的事故都有十分重要的意义。但如果使用不当,不仅达不到预期目的,有时甚至给系统带来不良影响。因此,我们将NXQ 型蓄能器在推广应用中所取得的经验作些介绍,供大家使用时参考。
NXQ (A) capsule-type accumulator is a newer multi-function hydraulic components. This article describes its use as a hydraulic system for storing energy and absorbing pressure pulsating elements when used correctly. NXQ (A) capsule-type accumulator (hereinafter referred to as NXQ-type accumulator), is an inflatable insulated accumulator. Since the adoption of the series of appraisals in 1980, not only the output has been greatly increased, but also it has been widely applied. At present, this series of accumulators have nominal capacities of 0.6L (20mm diameter), 1.6L, 2.5L, 4L, 6.3L (32mm diameter), 10L, 16L, 25L, 40L Working pressure is 10MPa, 20MPa, 31.5MPa. NXQ-type accumulator has the advantages of simple structure, good capsule air tightness, fast dynamic response, convenient installation and use. In the hydraulic system, its main function is to store energy, absorbing pulsating pressure and impact pressure. And its proper use, to improve the hydraulic system energy efficiency and quality indicators, improve the working accuracy of the implementing agencies to extend the life of systems and components, to avoid or reduce the pressure pulsation or pressure shock caused by accidents are of great significance. However, if used improperly, not only fail to achieve the desired purpose, and sometimes even have a negative impact on the system. Therefore, we introduce the experience gained in the promotion and application of NXQ accumulators for reference when we use them.
