【摘要】：深海水下分離器液壓控制系統(tǒng)主要用于控制水下分離器上各閥門的開啟和關(guān)閉,實現(xiàn)控制各個進(jìn)出口油氣水的流量和壓力等,從而保證水下分離器高效安全的工作。本文按照“先選執(zhí)行機(jī)構(gòu),后設(shè)計液壓管線及液壓附件”的方法,通過理論計算、理論推導(dǎo)和動態(tài)仿真分析研究了深海水下分離器的液壓控制系統(tǒng)。 首先介紹了水下分離器的機(jī)械結(jié)構(gòu)和液壓系統(tǒng),闡述了研究水下分離器液壓控制系統(tǒng)的目的和意義。確定出液壓控制系統(tǒng)總體結(jié)構(gòu)為:水上液壓控制系統(tǒng)、液壓管線及水下液壓控制系統(tǒng)。接著根據(jù)液壓控制系統(tǒng)的設(shè)計方法,通過理論計算,確定出執(zhí)行機(jī)構(gòu)、水上蓄能器和水下蓄能器的容積;同時對控制回路內(nèi)多個控制閥進(jìn)行了結(jié)構(gòu)設(shè)計和參數(shù)計算。然后對液壓軟管建立數(shù)學(xué)模型,通過理論推導(dǎo),推導(dǎo)出長軟管的液阻、液容和液感特性,得出長軟管的液阻特性。最后借助液壓仿真軟件AMESim對定壓輸出減壓閥和換向閥進(jìn)行了仿真研究,得出減壓閥可以保證液壓油壓力的穩(wěn)定,換向閥換向動作迅速,輸出流量大,能夠及時進(jìn)行換向。根據(jù)液壓控制系統(tǒng)原理圖建立了系統(tǒng)的仿真模型,并進(jìn)行了詳細(xì)的動態(tài)仿真。從仿真結(jié)果得出,執(zhí)行機(jī)構(gòu)能夠在規(guī)定時間內(nèi)對閥門的開度進(jìn)行及時的開啟和關(guān)閉。同時還仿真分析了當(dāng)系統(tǒng)出現(xiàn)故障時,無法順利的關(guān)閉執(zhí)行機(jī)構(gòu),啟動HPU泄壓閥,對執(zhí)行機(jī)構(gòu)進(jìn)行泄壓。通過仿真分析得出,泄壓閥可以在規(guī)定的時間內(nèi)關(guān)閉多個執(zhí)行機(jī)構(gòu),保證系統(tǒng)的安全。
[Abstract]:The hydraulic control system of deep-sea underwater separator is mainly used to control the opening and closing of each valve on the underwater separator, and to control the flow and pressure of each inlet, outlet, oil, gas and water, so as to ensure the high efficiency and safety work of the underwater separator. In this paper, according to the method of "first selecting the actuator, then designing the hydraulic pipeline and the hydraulic accessories", the theoretical calculation is carried out. The hydraulic control system of deep-sea underwater separator is studied by theoretical derivation and dynamic simulation. Firstly, the mechanical structure and hydraulic system of underwater separator are introduced, and the purpose and significance of studying hydraulic control system of underwater separator are expounded. The overall structure of hydraulic control system is: water hydraulic control system, hydraulic pipeline and underwater hydraulic control system. Then, according to the design method of hydraulic control system, the volume of actuators, water accumulators and underwater accumulators is determined by theoretical calculation. At the same time, the structure design and parameter calculation of many control valves in the control circuit are carried out. Then the mathematical model of hydraulic hose is established, and the characteristics of liquid resistance, liquid volume and liquid inductance of long hose are deduced by theoretical derivation, and the liquid resistance characteristic of long hose is obtained. Finally, with the aid of the hydraulic simulation software AMESim, the constant pressure output pressure reducing valve and the directional valve are simulated and studied. It is concluded that the pressure reducing valve can guarantee the stability of the hydraulic oil pressure, the reversing valve moves quickly, the output flow is large, and the reversing valve can carry on the commutation in time. According to the schematic diagram of hydraulic control system, the simulation model of the system is established, and the detailed dynamic simulation is carried out. The simulation results show that the actuator can open and close the valve in time. At the same time, it is also simulated and analyzed that when the system fails, it can not close the actuator smoothly, start the HPU relief valve, and discharge the pressure to the actuator. The simulation results show that the relief valve can close several actuators in a specified time to ensure the safety of the system.
