工作原理 Working prin

1、常規(guī)工作：
(1)閥門(mén)開(kāi)啟：?jiǎn)?dòng)電機(jī)帶動(dòng)油泵運(yùn)轉(zhuǎn)，液壓油經(jīng)濾網(wǎng)、油泵、單向閥、手動(dòng)截止閥進(jìn)入蓄能罐至額定壓力后停止。電磁閥通電，蓄能罐內(nèi)的壓力油經(jīng)高壓膠管進(jìn)入擺動(dòng)油缸(以下簡(jiǎn)稱油缸)的尾端，推動(dòng)活塞桿伸出，帶動(dòng)與之相連的連桿和閥軸，使蝶板旋轉(zhuǎn)開(kāi)啟，液壓油從油缸的前部排出，經(jīng)調(diào)整閥，電磁換向閥流回油箱，實(shí)現(xiàn)可調(diào)的無(wú)級(jí)勻速開(kāi)閥。隨之，蓄能罐充壓力油至額定壓力后油泵停止(參見(jiàn)液壓原理圖)。
(2)閥門(mén)關(guān)閉：切斷電磁閥電源(或反作用型即電磁閥通電)，蓄能罐內(nèi)的壓力油進(jìn)入油缸的前部，推動(dòng)活塞桿退回，液壓油從油缸尾端的快慢開(kāi)角度調(diào)節(jié)桿，快關(guān)調(diào)速閥，慢關(guān)調(diào)速閥流回油箱，按預(yù)先調(diào)定的3個(gè)控制程序?qū)崿F(xiàn)關(guān)閥。
(3)任意位置停止：蝶閥在開(kāi)啟或關(guān)閉過(guò)程中，切斷油缸的回油，蝶板即停止在任意位置(此功能不能調(diào)節(jié)流量使用)。
2、電動(dòng)油泵直接供壓力油開(kāi)、關(guān)蝶閥：切斷蓄能罐內(nèi)的壓力油、關(guān)閉手動(dòng)形式上閥J1、J2(參見(jiàn)液壓原理圖)。啟動(dòng)電機(jī)、油泵的壓力油分別進(jìn)入油缸的后端或前部即可實(shí)現(xiàn)勻速開(kāi)、閉蝶閥。
3、搖動(dòng)手動(dòng)油泵開(kāi)、關(guān)蝶閥：(切斷蓄能罐內(nèi)的壓力油和關(guān)掉電動(dòng)油泵)電磁閥得電或失電，搖動(dòng)手動(dòng)動(dòng)油泵即可實(shí)現(xiàn)開(kāi)、關(guān)蝶閥。
4、蓄能罐補(bǔ)壓力油：一般情況下，蓄能罐內(nèi)的油壓為額定值(上限值)，當(dāng)液壓系統(tǒng)在長(zhǎng)時(shí)間的工作狀態(tài)下，由于有極微量泄漏使油壓降至額定值(下限值)(仍高于工作油壓值)時(shí)，壓力控制器動(dòng)作，啟動(dòng)油泵電機(jī)進(jìn)行補(bǔ)壓力油。油泵啟動(dòng)間隔時(shí)間為：閥門(mén)通徑DN≤900大于300小時(shí)，DN≥1000大于500小時(shí)。
5、蝶閥、水泵聯(lián)鎖保護(hù)：當(dāng)電磁換向閥出現(xiàn)故障(換向失控)或誤操作時(shí)，聯(lián)鎖裝置即發(fā)出跳閘信號(hào)，使水泵停止運(yùn)轉(zhuǎn)。
1. Routine work:
(1) valve opening: start the motor to drive the pump operation, hydraulic oil through the filter screen, oil pump, one-way valve, manual globe valve to enter the storage tank to the rated pressure to stop.The solenoid valve is energized and the pressure oil in the storage tank is pumped through a high pressure hoseInto swinging the end of the cylinder (hereinafter referred to as the cylinder), to push the piston rod, drive shaft is connected with the connecting rod and valve, rotate and open the butterfly plate and the front of the hydraulic oil from the oil cylinder, adjusted valve, electromagnetic directional valve flow back to the fuel tank, real
Now adjustable non-uniform open valve.Subsequently, the storage tank is filled with pressure oil until the pump stops (see the hydraulic schematic diagram).Electromagnetic valve (2) : the valve closed to cut off the power supply (or reaction type solenoid valve power), the front of the energy storage tank pressure oil into the cylinder, the push rod returned, the hydraulic oil from the oil cylinder end opening Angle adjusting screw rod, fast shut
The speed regulating valve, the slow speed control valve flow back to the tank, according to the preset three control procedures to realize the valve.
(3) stop at any position: in the process of opening or closing the butterfly valve, the oil cylinder is cut off and the butterfly plate is stopped in any position (this function cannot regulate the flow).
2. The electric oil pump is directly used for pressure oil and the butterfly valve: cut off the pressure oil in the storage tank, and close the manual valve J1 and J2 (see hydraulic schematic diagram).The pressure oil of starting motor and oil pump goes into the back end or front of the cylinder. The department can achieve uniform speed and close butterfly valve.
3. Shake the manual oil pump to open and close the butterfly valve: (cut off the pressure oil from the storage tank and turn off the electric oil pump) the solenoid
valve can be turned off or lost, and the pump can be opened and closed.
4, energy storage tank pressure oil: under normal circumstances, the energy storage tank for oil pressure rating (upper limit), when the hydraulic system under the working condition for a long time, because have very low leakage oil pressure drop to rating (lower limit) (still above
When working oil pressure value, the pressure controller action, start the oil pump motor to make up the pressure oil.The starting interval of oil pump is: the valve size DN is less than 900, which is greater than 300 hours, and the DN is greater than 1000 hours.
5. Butterfly valve and water pump interlock protection: when the solenoid reversing valve fails (out of control) or misoperation, the interlock device sends out the tripping signal to stop the pump running.
