下面就來看下啟動(dòng)后的8個(gè)使用規(guī)范技巧
1、將開關(guān)屏上調(diào)壓選擇開關(guān)置于手動(dòng)位置;
2、打開燃油開關(guān),同時(shí)將燃油控制手柄固定在700轉(zhuǎn)/分左右的油門位置;
3、用高壓油泵開關(guān)手柄連續(xù)地手動(dòng)泵油,直到有泵油阻力,噴油器發(fā)出清脆的吱聲為止;
4、將油泵開關(guān)手柄放在工作位置上,減壓閥推向減壓位置;
5、用手搖手柄或按下電啟動(dòng)按鈕起動(dòng)柴油機(jī),當(dāng)柴油機(jī)達(dá)到一定轉(zhuǎn)速時(shí),把減軸迅速拉回工作位置,使柴油機(jī)點(diǎn)火起動(dòng);
6、柴油機(jī)起動(dòng)后,將電鑰匙撥回中間位置,轉(zhuǎn)速應(yīng)控制在600~700轉(zhuǎn)/分,并密切組注意機(jī)油壓力,表的指示(工作油壓值詳見各類柴油機(jī)使用說明書),若油壓無指示,應(yīng)立即停機(jī)檢查;
7、若機(jī)組低速運(yùn)轉(zhuǎn)正常,可將轉(zhuǎn)速逐漸增加到1000~1200轉(zhuǎn)/分預(yù)熱運(yùn)轉(zhuǎn),當(dāng)水溫 度在50~60℃,機(jī)油溫度達(dá)到45℃左右時(shí),再將轉(zhuǎn)速增加到1500轉(zhuǎn)/分,觀察配電屏頻率表應(yīng)在50赫芝左右,電壓表為380~410伏,如果電壓偏高或偏低時(shí)可調(diào)節(jié)磁場(chǎng)變阻器;
8、若機(jī)組工作正常,可合上發(fā)電機(jī)與負(fù)栽間的空氣開關(guān),然后逐漸增加負(fù)栽,向外送電;
溫馨提示大家,1、各類柴油機(jī)起動(dòng)應(yīng)按其柴油機(jī)使用維護(hù)說明書要求進(jìn)行,2、在調(diào)壓時(shí)如機(jī)組存放過久,發(fā)電機(jī)失磁,電壓建立不起來,此時(shí)可用蓄電池充磁,充磁時(shí)磁場(chǎng)繞組L1(+)接蓄電池正極L2(-)接蓄電池負(fù)極,切不可接錯(cuò),3、若按下按鈕10秒,不能點(diǎn)火起動(dòng),應(yīng)等一分鐘左右再作第二次起動(dòng),若連續(xù)三次失敗,應(yīng)查明故障原因再行起動(dòng)。
上述就是關(guān)于發(fā)電機(jī)組啟動(dòng)后的8個(gè)使用規(guī)范技巧的介紹,注意這些使用規(guī)范,不僅能讓柴油發(fā)電機(jī)組更好的工作,同時(shí)對(duì)延長(zhǎng)柴油發(fā)電機(jī)組壽命也很有幫助。
8 tips for using a diesel generator set after starting up. Many people believe that after a diesel generator set starts up normally, there is no need to take care of it. However, this is not true because it is the easiest time for a diesel generator set to malfunction. So it is also necessary to conduct regular inspections at this time to ensure the normal operation of the generator set.
Let's take a look at 8 usage guidelines after startup
1. Place the voltage selection switch on the switch screen in the manual position;
2. Turn on the fuel switch and fix the fuel control lever at the throttle position of around 700 revolutions per minute;
3. Use the high-pressure oil pump switch handle to manually pump oil continuously until there is pump resistance and the fuel injector makes a crisp creaking sound;
4. Place the oil pump switch handle in the working position and push the pressure reducing valve to the pressure reducing position;
5. Start the diesel engine with a hand crank or by pressing the electric start button. When the diesel engine reaches a certain speed, quickly pull the reduction shaft back to the working position to ignite and start the diesel engine;
6. After starting the diesel engine, turn the electric key back to the middle position, and the speed should be controlled at 600-700 revolutions per minute. Pay close attention to the oil pressure and the indication on the gauge (see various diesel engine manuals for the working oil pressure value). If there is no indication of oil pressure, stop the machine immediately for inspection;
7. If the unit operates normally at low speed, the speed can be gradually increased to 1000-1200 revolutions per minute for preheating operation. When the water temperature is between 50-60 ℃ and the oil temperature reaches around 45 ℃, the speed can be increased to 1500 revolutions per minute. The frequency meter on the distribution screen should be around 50 Hz, and the voltage meter should be 380-410 volts. If the voltage is too high or too low, the magnetic field variable resistor can be adjusted;
8. If the unit is working normally, the air switch between the generator and the negative load can be closed, and then the negative load can be gradually increased to transmit power to the outside;
Kind reminder to everyone: 1. All types of diesel engines should be started according to the requirements of their diesel engine maintenance manual. 2. If the unit is stored for too long during voltage regulation, the generator will lose magnetism and the voltage cannot be established. At this time, the battery can be used for magnetization. When magnetizing, the magnetic field winding L1 (+) should be connected to the positive pole of the battery and L2 (-) should be connected to the negative pole of the battery, and must not be connected incorrectly. 3. If the button is pressed for 10 seconds and the ignition cannot be started, wait for about one minute before starting again. If it fails three times in a row, the cause of the fault should be identified before starting again.
The above is an introduction to the 8 usage guidelines and techniques for starting a generator set. Paying attention to these usage guidelines can not only improve the performance of diesel generator sets, but also help extend their lifespan.
