【摘要】：大型重载工程车辆在工程建设中至关重要,其润滑和维护是保证工程车辆正常运行和降低成本的重要环节。传统的手动润滑费时费力,润滑量和效果无法保证。现有的大型工程机械集中润滑结构复杂,无法实现精准注油,智能化程度不高。本文针对动力平板车的润滑需求,开展了新型智能集中润滑系统研究。本文开发出智能集中润滑系统,设计了自动多流量泵,并对动力平板车集中润滑系统换向阀进行仿真模拟。本文的主要工作和成果如下:(一)阐述动力平板车概况、结构以及润滑情况,根据现有的润滑技术,确定总体润滑方案,针对动力平板车润滑需求进行润滑装置结构设计和选型,确定设计参数,优化集中润滑系统。(二)针对动力平板车集中润滑系统润滑工况,设计自动多流量集中润滑系统。创新设计一种自动多流量泵单元,实现润滑系统的自动注油,同时可以供给多达30路5种流量,使各个供油支路相互独立,避免传统递进式供油系统各支路相互干扰的弊端。(三)借助Fluent软件对润滑系统的部件进行模拟,分析验证部件结构设计的合理性,为润滑系统设计提供参考。(四)根据润滑系统原理,设计智能化控制系统。使用贝加莱集成化工控机搭建工控机-PLC-I/O控制平台,实现控制系统的无缝通信与连接。最后基于贝加莱Automation Studio开发动力平板车集中润滑系统软件,实现集中润滑系统的自动控制与实时动态记录监测,便于集中润滑系统的工程实现。本文研制的动力平板车集中润滑系统由控制系统、新型自动多流量泵、输油装置等构成。实现了系统的自动注油、自动供油、多流量供油等功能,具有管路压力损失小、能耗低、智能化程度高等优点。
[Abstract]:Large heavy load engineering vehicles are very important in the construction of engineering. Their lubrication and maintenance are important links to ensure the normal operation of the engineering vehicles and reduce the cost. The traditional manual lubrication is time-consuming and difficult to ensure the quantity of lubrication and the effect of the existing large-scale construction machinery. This paper develops a new intelligent centralized lubrication system for the lubrication requirement of the power flat car. This paper develops an intelligent centralized lubrication system, designs an automatic multi flow pump, and simulates the reversing valve of the centralized lubrication system of the power flat car. The main work and results of this paper are as follows: (I) the general situation of the power flat car is expounded. Structure and lubrication, according to the existing lubrication technology, determine the overall lubrication scheme, design and select the structure of the lubricating device for the lubrication requirements of the power flat car, determine the design parameters and optimize the centralized lubrication system. (two) aiming at the lubrication condition of the centralized lubrication system of the power flat car, the design of the automatic multi flow centralized lubrication system is designed. An automatic multi flow pump unit is designed to realize the automatic oil injection of the lubricating system. At the same time, it can supply as many as 30 roads and 5 kinds of flow, make each oil supply branch independent and avoid the interference of each branch of the traditional progressive oil supply system. (three) the components of the lubricating system are simulated with the aid of Fluent software, and the structural design of the components is analyzed and verified. The rationality of the design provides reference for the design of lubrication system. (four) according to the principle of the lubrication system, the intelligent control system is designed. The -PLC-I/O control platform of the industrial control machine is set up by the integrated chemical control machine of Bei Jia, and the seamless communication and connection of the control system are realized. Finally, based on the Automation Studio, the centralized lubrication system of the power flat car is developed. It realizes the automatic control and real-time dynamic recording and monitoring of the centralized lubrication system, which is convenient for the realization of the centralized lubrication system. The centralized lubrication system developed in this paper is composed of the control system, the new automatic multi flow pump, and the oil transporting device. The system has the functions of automatic oil injection, automatic oil supply and multi flow oil supply, etc. The pipeline has the advantages of small pressure loss, low energy consumption and high intelligence.
