沼氣發(fā)電機組如何處理轉速不穩定?
沼氣發(fā)電機組如何處理轉速不穩定?
How to deal with the unstable speed of biogas generator set?
一、無(wú)法開(kāi)始
1、 Can't start
1.無(wú)速度反饋信號:檢查速度傳感器和電纜。
1. No speed feedback signal: check speed sensor and cable.
2.調速器電源斷開(kāi)或反向連接:檢查電源和線(xiàn)路。
2. Governor power disconnection or reverse connection: check power supply and circuit.
3.節流堵塞:重新安裝和調試。
3. Throttling blockage: reinstallation and commissioning.
4.啟動(dòng)油量設定值過(guò)低:適當增加啟動(dòng)油量。
4. The setting value of starting oil is too low: increase the starting oil properly.
5.速度設置過(guò)低:順時(shí)針旋轉低速電位器，增加空轉速度。
5. Speed setting too low: turn the low-speed potentiometer clockwise to increase the idle speed.
二、開(kāi)始加速
2、 Start to accelerate
1.執行機構和節氣門(mén)機構減少氣體方向或零位置不匹配:檢查和重新安裝調整。
1. Actuator and throttle mechanism reduce gas direction or zero position mismatch: check and reinstall.
2.速度控制系統速度設定過(guò)高:將低速設定值調整到校準設定值。
2. Speed setting of speed control system is too high: adjust the low speed setting value to the calibration setting value.
3.調速器電流限制過(guò)高:適當減少起動(dòng)油量。
3. Governor current limit is too high: reduce starting oil properly.
4.控制器參數調整不當:適當增加控制器的“增益”和“差動(dòng)”。
4. Improper adjustment of controller parameters: properly increase the "gain" and "differential" of the controller.
三、速度不穩定
3、 Speed instability
1.傳動(dòng)桿系統卡死或執行機構與節流閥間隙:檢查并重新安裝調整。
1. The transmission rod system is stuck or the clearance between the actuator and the throttle valve is checked and reinstalled for adjustment.
2.發(fā)動(dòng)機過(guò)載:減少發(fā)動(dòng)機負荷。
2. Engine overload: reduce engine load.
3.速度傳感器安裝間隙過(guò)大:檢查并重新安裝和調整。
3. The installation clearance of speed sensor is too large: check, reinstall and adjust.
4.控制器參數調整不當:調整增益、差動(dòng)和狀態(tài)開(kāi)關(guān)。
4. Improper adjustment of controller parameters: adjust gain, differential and status switches.
5.如果屏蔽線(xiàn)連接不正確，電磁干擾會(huì )造成不穩定:檢查屏蔽線(xiàn)連接是否正確。
5. If the shield wire is not connected correctly, electromagnetic interference will cause instability: check whether the shield wire is connected correctly.
以上方案不限于沼氣發(fā)電機組、天然氣發(fā)電機組、燃氣發(fā)電機組、生物質(zhì)燃氣發(fā)電機組、燃氣發(fā)電機組等，也可執行上述操作。
The above scheme is not limited to biogas generator set, natural gas generator set, gas generator set, biomass gas generator set, gas generator set, etc., but also can perform the above operations.
