摘要

目的。确认脉冲保护方法对液压冲击的有效性,为进一步推广研究和开发适用于实施所提出的保护方法的合适装置获得数据。方法。为了实现这一目标,建立了一个数学模型,描述了装有液压阻力增加装置的抽油机关闭后管道中的瞬态过程。在MATLAB软件环境下进行了计算机实验。结果。脉冲方法的有效性,防止液压冲击,开始一波压力降低,已被证实。科学的新奇。提出了一种具有增大水力阻力装置的抽油机关闭后管路瞬态过程的计算算法。研究结果验证了所提出的脉冲液压冲击保护方法的有效性。现实意义。针对使用射流二极管时,反向阻力不足以有效耗散液压冲击能的问题,提出了在关闭抽油机后增加管道双向液压阻力的方法。指定的方法称为脉冲,因为它是由特殊保护装置产生的局部液压阻力的快速变化组成的。这种保护方法可以使用基于机电一体化的设备来实现。关键词:矿井排水,液压冲击,压力管道,过渡过程,冲击法,水力阻力。

EFFICIENCY OF THE IMPULSE METHOD OF PROTECTION AGAINST HYDRAULIC SHOCKS IN ENSURING THE SAFETY OF MINE OUTFLOWS
Purpose. Confirmation of the effectiveness of the impulse method of protection against hydraulic shocks, obtaining data for further generalization of research and development of a suitable device for the implementation of the proposed protection method. Methodology.To achieve the goal, a mathematical model was created that describes the transient process in the pipeline of a pumping unit equipped with a device for increasing hydraulic resistance after the pump unit is turned off. A computer experiment was conducted using the MATLAB software environment. Results.The effectiveness of the impulse method of protection against hydraulic shocks, which begin with a wave of pressure reduction, has been confirmed. Scientific novelty. An algorithm for calculating the transient process in the pipeline of a pumping unit equipped with a device for increasing hydraulic resistance after the pump unit is turned off has been developed. The research results were obtained, confirming the effectiveness of the proposed impulse method of protection against hydraulic shocks. Practical significance. Taking into account that when using jet diodes, the reverse resistance is insufficient for effective dissipation of hydraulic shock energy, a method is proposed, which consists in increasing the hydraulic resistance of the pipeline in both directions after turning off the pumping unit. The specified method is called pulsed, as it consists in a rapid change in local hydraulic resistance, which is created by special protection devices. This method of protection can be implemented using mechatronic-based devices. Keywords: mine drainage, hydraulic shock, pressure pipeline, transition process, impulse method, hydraulic resistance.
