基于AMESim的煤矿带式输送机递进式分配器干油润滑特性仿真与分析

Simulation and Analysis of Dry Oil Lubrication Characteristics of Progressive Distributor for Coal Mine Belt Conveyor Based on AMESim

摘要: 针对煤矿井下带式输送机干油集中润滑系统中递进式分配器动态特性研究不足的问题，以某矿主斜井带式输送机为研究对象，基于AMESim仿真平台建立递进式分配器仿真模型，系统分析了系统工作压力(10~35 MPa)、活塞直径(8~14 mm)及黏性摩擦系数(1000~3000 N·s/m)对分配器活塞运动特性和出油口流量稳定性的影响规律。结果表明：系统工作压力对分配器启动特性与运行稳定性具有显著影响，推荐工作压力为15~20 MPa；活塞直径与单出口给油量呈平方正比关系，推荐选用活塞直径10~12 mm的分配器中间片；黏性摩擦系数取2000~3000 N·s/m时，分配器可在响应速度与运动平稳性之间取得较好平衡。研究结果为煤矿带式输送机干油润滑系统的设计与优化提供了理论依据。

Abstract: To address the insufficient research on the dynamic characteristics of progressive distributors in dry oil centralized lubrication systems for underground belt conveyors in coal mines, taking the main inclined shaft belt conveyor of a coal mine as the research object, a simulation model of the progressive distributor was established based on the AMESim platform. The effects of system working pressure (10~35 MPa), piston diameter (8~14 mm), and viscous friction coefficient (1000~3000 N·s/m) on the piston motion characteristics and outlet flow stability of the distributor were systematically analyzed. The results show that the system working pressure significantly affects the starting characteristics and operational stability of the distributor, with a recommended working pressure of 15~20 MPa. The piston diameter exhibits a quadratic proportional relationship with the oil delivery volume per outlet, and a piston diameter of 10~12 mm is recommended for the drive drum bearing. When the viscous friction coefficient is set between 2000 and 3000 N·s/m, the distributor achieves a favorable balance between response speed and motion stability. The findings provide a theoretical basis for the design and optimization of dry oil lubrication systems for belt conveyors in coal mines.
