精彩回顾｜普茨迈斯特充填大会报告：以创新脉冲阻尼方案，让膏体充填更稳定更高效

Event Recap | Putzmeister at the Backfill Conference: Innovative Pulsation Dampening for More Stable, More Efficient Paste Backfill今日在本次中国膏体充填采矿国际学术研讨会 上，普茨迈斯特工业技术全球业务总监陆托比先生Tobias Lutz围绕“膏体充填泵的创新冲动阻尼概念”作专题报告，现场反响热烈。报告展现了我司核心PCF和HPD技术、逻辑清晰，从膏体充填背景、泵送挑战到PCF解决方案与工程参考，层层递进，充分展现了"大象泵"在膏体充填泵送领域的技术积累与差异化优势。

Today, at this China International Symposiumon Cemented Paste Backfill Mining, Mr. Tobias Lutz, Global Business Directorof Industrial Technology at Putzmeister, delivered a presentation on"Innovative Pulsation Dampening Concepts for Paste Backfill Pumps," whichreceived an enthusiastic response from the audience.The presentation showcasedour core PCF and HPD technologies with clear logic, progressing step by stepfrom the background of paste backfill and pumping challenges to the PCFsolution and engineering references. It fully demonstrated the "Elephant Pump"(Putzmeister)'s technological accumulation and differentiated advantages inthe field of paste backfill pumping.

报告要点回顾 Report Highlights：* 背景： 膏体充填将尾矿转化为可控地下材料，兼顾采场支撑、尾矿与水管理。

* 挑战： 活塞泵换向造成临时流量中断，引发压力波与反射，可能放大的压力峰值，增加管道动态载荷。

* 方案： PCF系统通过预压缩与同步油缸交接，稳定联合排出流量，从源头减少流量中断。HPD实际上作为第三输送缸，通过泵法兰后面的t形法兰与输送管道连接。HPD在泵的每个输送行程中充满。在换向柱塞泵时，第三缸的内容物被主动地推入输送管道。

* 优势： 减少压力瞬态、降低管道动态载荷、具备能效潜力，且管道内无需额外阻尼元件，便于清洗维护。

* Advantages: Reduced pressure transients, lower dynamic pipeline loads, potential for energy efficiency, and no additional damping components in the pipeline, facilitating cleaning and maintenance.

* Background: Cemented paste backfill (CPB) converts tailings into a controlled underground material, integrating stope support with tailings and water management.

* Challenge: Piston pump changeover causes temporary flow interruption, triggering pressure waves and reflections, potentially amplifying pressure peaks and increasing dynamic pipeline loads.

* Solution: The PCF system stabilizes the combined discharge flow through precompression and synchronized cylinder handover, reducing flow interruption at the source. The HPD actually acts as a third delivery cylinder, connected to the delivery pipeline via a T-shaped flange behind the pump flange. The HPD is charged during each delivery stroke of the pump.
