【摘要】：在生產過程中經常會出現壓力沖擊問題,它常發(fā)生在啟閉閥門、液壓泵突然開停、執(zhí)行元件的緊急制動、換向閥突然換向時。這種沖擊嚴重時會使管子爆裂,損壞儀表和密封裝置并產生很大的振動和噪聲,嚴重威脅生產安全。在化工生產中常常出現這種沖擊現象,如在腈綸生產線中的擠水環(huán)節(jié),就常因為換向閥突然換向而產生壓力沖擊,對擠水液壓缸的穩(wěn)定造成了影響,沖擊大時甚至使得生產停止。所以如何減小液壓沖擊的問題顯得至關重要。 本文以克服壓力沖擊為主題,獨特地從三個不同的角度考慮來解決沖擊問題。從吸收壓力沖擊角度考慮可以使用蓄能器;從隔斷壓力沖擊角度考慮可以使用液壓鎖;從反饋壓力沖擊角度考慮可以使用伺服控制系統(tǒng)。三種系統(tǒng)的設計都能滿足單泵多執(zhí)行器的工作要求,使系統(tǒng)能夠平穩(wěn)工作而不受壓力波動的影響。 所以本文的主要內容是三種抗沖擊系統(tǒng)的設計和仿真。首先,對三種系統(tǒng)的工作原理和主要元件的結構進行研究;其次,分析系統(tǒng)的抗沖擊原理,建立數學模型并仿真分析;最后為了仿真實際腈綸生產線上的液壓沖擊,用AMESim軟件建立了三種系統(tǒng)的模型并進行仿真分析。
[Abstract]:In the process of production, pressure shock often occurs when the valve is opened and closed, the hydraulic pump is suddenly opened and stopped, the actuators are actuated by emergency braking, and the directional valve is suddenly reversed. When the impact is serious, the pipe will burst, damage the instrument and seal device, and produce a lot of vibration and noise, which seriously threaten the safety of production. This kind of impact phenomenon often occurs in chemical production. For example, in the water extrusion link of acrylic fiber production line, the pressure shock is often caused by the sudden reversing of the reversing valve, which has an impact on the stability of the hydraulic cylinder. When the impact is great, production even stops. So how to reduce the problem of hydraulic impact is very important. This paper deals with the problem of shock from three different angles with the theme of overcoming pressure shock. The accumulator can be used from the angle of absorbing pressure shock, the hydraulic lock can be used from the angle of separating pressure shock, and the servo control system can be used from the angle of feedback pressure shock. The design of the three systems can meet the requirements of single pump and multiple actuators, so that the system can work smoothly without the influence of pressure fluctuation. So the main content of this paper is the design and simulation of three shock-resistant systems. Firstly, the working principle of the three systems and the structure of the main components are studied. Secondly, the anti-impact principle of the system is analyzed, and the mathematical model is established and simulated. Finally, in order to simulate the hydraulic impact on the actual acrylic fiber production line, The models of three kinds of systems are established by AMESim software and the simulation analysis is carried out.
