【摘要】：随着沈鼓集团齿轮压缩机产品任务量的增多,原有的试车台位已经无法满足整个集团的试车要求。所以针对齿轮压缩机产品的性能特点和试车要求,为齿轮压缩机组设立了专用试车台控制装置。压缩机组的试车台装置对于压缩机组产品非常重要。通过压缩机的出厂前的试车试验可以在机组出厂前就能发现并解决问题。通过机组的连续运转试车试验,来检验机组的各项性能指标是否达到用户的需求。本文在分析了齿轮压缩机的类型以及驱动压缩机的试验电机等重要设备的工作原理和工作特点的基础上,详细论述了压缩机的主要性能以及压缩机的控制方法。重点论述了压缩机性能试验的主要调节方式。并针对压缩机调节方式的不同,给出了不同控制方式的闭环调节控制方案,并提出了模糊PID控制方法。在本文中,还从机组的报警联锁控制、机组的流量或压力控制,压缩机组的防喘振控制,以及压缩机辅助设备润滑油站的控制等方面入手,综合解决了有关齿轮压缩机的控制问题,从而满足试车台装置的整体控制要求。试车台项目不同于普通控制系统项目,它任务量大,必须能适应多种压缩机型,需要有多种性能调节和控制方式结合使用,并能根据试车需要,来选择调节方法。合理的硬件配置是建立控制系统的首要任务。根据试车台控制系统的整体控制方案,完成了压缩机的仪表检测和PLC控制系统硬件设计。在硬件设计的基础上,进行了控制系统的软件开发设计。采用的上位机软件具有友好的用户界面,易于修改,便于操作,维护方便。整个控制系统体系设计合理、功能完备、结构简洁、易于维护和扩展、响应速度快、控制精确、人机界面友好,可以全面的完成齿轮压缩机组的试车任务,具备良好的应用前景,实现了控制的最优化设计。
[Abstract]:With the increase of product quantity of gear compressor in Shengu Group, the original test bench can not meet the requirements of the whole group.Therefore, according to the performance characteristics of gear compressor products and test requirements, a special test bench control device is set up for the gear compressor unit.The test bench device of compressor unit is very important for compressor unit product.The problems can be found and solved before the unit leaves the factory through the test test before the compressor leaves the factory.Through the continuous operation test, to verify the performance of the unit to meet the needs of the user.Based on the analysis of the type of gear compressor and the working principle and working characteristics of the important equipment such as the driving compressor, the main performance of the compressor and the control method of the compressor are discussed in detail in this paper.The main regulating methods of compressor performance test are discussed emphatically.According to the different regulating modes of compressor, the closed loop control scheme of different control methods is given, and the fuzzy PID control method is put forward.In this paper, the alarm interlock control of the unit, the flow or pressure control of the unit, the anti-surge control of the compressor unit, and the control of the lubricating oil station of the auxiliary equipment of the compressor are also discussed.The control problem of gear compressor is solved synthetically, so as to meet the overall control requirements of the test bench.The test-bed project is different from the common control system project, it must be able to adapt to many kinds of compressor type, it must be able to adapt to many kinds of compressor type, and need to have a variety of performance adjustment and control mode combined use, and can choose the adjustment method according to the need of the test run.Reasonable hardware configuration is the primary task of establishing control system.According to the overall control scheme of the test-bed control system, the instrument detection of the compressor and the hardware design of the PLC control system are completed.Based on the hardware design, the software design of the control system is carried out.The software has a friendly user interface, easy to modify, easy to operate, easy to maintain.The whole control system is reasonable in design, complete in function, simple in structure, easy to maintain and expand, fast in response, accurate in control, friendly in man-machine interface.It has a good application prospect and realizes the optimal design of control.
