style="text-indent:25px">發(fā)電機(jī)工作特性：表征同步發(fā)電機(jī)性能的主要是空載特性和負(fù)載運(yùn)行特性。這些特性是用戶選用發(fā)電機(jī)的重要依據(jù)?？蛰d特性：發(fā)電機(jī)不接負(fù)載時(shí)，電樞電流為零，稱為空載運(yùn)行。此時(shí)電機(jī)定子的三相繞組只有勵(lì)磁電流If感生出的空載電動(dòng)勢(shì)E0（三相對(duì)稱），其大小隨If的增大而增加。但是，由于電機(jī)磁路鐵心有飽和現(xiàn)象，所以兩者不成正比。反映空載電動(dòng)勢(shì)E0與勵(lì)磁電流If關(guān)系的曲線稱為同步發(fā)電機(jī)的空載特性，珠海室外柴油發(fā)電機(jī)廠商。電樞反應(yīng)：當(dāng)發(fā)電機(jī)接上對(duì)稱負(fù)載后，電樞繞組中的三相電流會(huì)產(chǎn)生另一個(gè)旋轉(zhuǎn)磁場(chǎng)，稱電樞反應(yīng)磁場(chǎng)。其轉(zhuǎn)速正好與轉(zhuǎn)子的轉(zhuǎn)速相等，兩者同步旋轉(zhuǎn)。同步發(fā)電機(jī)的電樞反應(yīng)磁場(chǎng)與轉(zhuǎn)子勵(lì)磁磁場(chǎng)均可近似地認(rèn)為都按正弦規(guī)律分布。它們之間的空間相位差取決于空載電動(dòng)勢(shì)E0與電樞電流I之間的時(shí)間相位差，珠海室外柴油發(fā)電機(jī)廠商。電樞反應(yīng)磁場(chǎng)還與負(fù)載情況有關(guān)。當(dāng)發(fā)電機(jī)的負(fù)載為電感性時(shí)，電樞反應(yīng)磁場(chǎng)起去磁作用，會(huì)導(dǎo)致發(fā)電機(jī)的電壓降低；當(dāng)負(fù)載呈電容性時(shí)，珠海室外柴油發(fā)電機(jī)廠商，電樞反應(yīng)磁場(chǎng)起助磁作用，會(huì)使發(fā)電機(jī)的輸出電壓升高。表征同步發(fā)電機(jī)性能的主要是空載特性和負(fù)載運(yùn)行特性。珠海室外柴油發(fā)電機(jī)廠商</p><div

style="text-indent:25px">汽油發(fā)動(dòng)機(jī)特點(diǎn)：由于汽油粘性小，蒸發(fā)快，可以在氣缸外部與空氣形成均勻的混合氣，然后將混合氣吸入氣缸，或用汽油噴射系統(tǒng)將汽油噴入氣缸，使氣體膨脹做功。汽油機(jī)的缺點(diǎn)是熱效率低于柴油機(jī)，泊耗較高，點(diǎn)火系統(tǒng)比柴油機(jī)復(fù)雜，可靠性和維修的方便性也不如柴油機(jī)。汽油發(fā)動(dòng)機(jī)應(yīng)用：由于在相同功率條件下，汽油機(jī)的尺寸與質(zhì)量都較柴油機(jī)??；轉(zhuǎn)矩特性好，啟動(dòng)和加速性能較好，運(yùn)轉(zhuǎn)噪聲較**造成本較低，因而汽油機(jī)的用途很廣，在飛機(jī)、汽車、快艇、賽車、小型農(nóng)機(jī)、園林機(jī)械甚至航模等都大量采用。</p><p style="text-indent:25px">交流異步測(cè)速發(fā)電機(jī)的誤差主要有：非線性誤差：由于直軸磁通變化使測(cè)速發(fā)電機(jī)產(chǎn)生非線性誤差；剩余電壓：實(shí)際運(yùn)行中，轉(zhuǎn)子靜止時(shí)，測(cè)速發(fā)電機(jī)輸出一個(gè)較小的電壓；相位誤差：由于勵(lì)磁繞組的漏抗、空心杯轉(zhuǎn)子的漏抗使輸出電壓與勵(lì)磁電壓的相位不同。交流同步測(cè)速發(fā)電機(jī)分為：永磁式、感應(yīng)式和脈沖式。柴油發(fā)電機(jī)：柴油發(fā)電機(jī)組是一種**的發(fā)電設(shè)備，系指以柴油等為燃料，以柴油機(jī)為原動(dòng)機(jī)帶動(dòng)發(fā)電機(jī)發(fā)電的動(dòng)力機(jī)械。整套機(jī)組一般由柴油機(jī)、發(fā)電機(jī)、控制箱、燃油箱、起動(dòng)和控制用蓄電瓶、保護(hù)裝置、應(yīng)急柜等部件組成。整體可以固定在基礎(chǔ)上，定位使用，亦可裝在拖車上，供移動(dòng)使用。柴油發(fā)電機(jī)組屬非連續(xù)運(yùn)行發(fā)電設(shè)備，若連續(xù)運(yùn)行超過12h，其輸出功率將低于額定功率約90%。風(fēng)力發(fā)電不可視為備用電源，但是卻可以長(zhǎng)期利用。</p><div

style="text-indent:25px">汽油發(fā)動(dòng)機(jī)的工作原理：發(fā)動(dòng)機(jī)是將化學(xué)能轉(zhuǎn)化為機(jī)械能的機(jī)器，它的轉(zhuǎn)化過程實(shí)際上就是工作循環(huán)的過程，簡(jiǎn)單來說就是是通過燃燒氣缸內(nèi)的燃料，產(chǎn)生動(dòng)能，驅(qū)動(dòng)發(fā)動(dòng)機(jī)氣缸內(nèi)的活塞往復(fù)的運(yùn)動(dòng)，由此帶動(dòng)連在活塞上的連桿和與連桿相連的曲柄，圍繞曲軸中心作往復(fù)的圓周運(yùn)動(dòng)，而輸出動(dòng)力的。四沖程汽油機(jī)的工作過程是一個(gè)復(fù)雜的過程，它由進(jìn)氣、壓縮、燃燒膨脹、排氣四個(gè)行程（沖程）組成。進(jìn)氣行程：此時(shí)，活塞被曲軸帶動(dòng)由上止點(diǎn)向下上止點(diǎn)移動(dòng)，同時(shí)，進(jìn)氣門開啟，排氣門關(guān)閉。當(dāng)活塞由上止點(diǎn)向下止點(diǎn)移動(dòng)時(shí)，活塞上方的容積增大，氣缸內(nèi)的氣體壓力下降，形成一定的真空度。由于進(jìn)氣門開啟，氣缸與進(jìn)氣管相通，混合氣被吸入氣缸。當(dāng)活塞移動(dòng)到下止點(diǎn)時(shí)，氣缸內(nèi)充滿了新鮮混合氣以及上一個(gè)工作循環(huán)未排出的廢氣。普通柴油機(jī)的供油系統(tǒng)是由發(fā)動(dòng)機(jī)凸輪軸驅(qū)動(dòng)，借助于高壓油泵將柴油輸送到各缸燃油室。珠海室外柴油發(fā)電機(jī)廠商</p><p
