信息摘要:

柴油發(fā)電機(jī)組啟動(dòng)馬達(dá)損壞的原因可能有以下幾種:1、啟動(dòng)時(shí)間過(guò)長(zhǎng),沒(méi)有按規(guī)定時(shí)間(約5s~10s)使用起動(dòng)機(jī),長(zhǎng)時(shí)間在未查明原因情況下連續(xù)啟動(dòng)起動(dòng)機(jī)。2、當(dāng)電刷磨損到原長(zhǎng)1/2時(shí),應(yīng)更換電刷。在維護(hù)起動(dòng)機(jī)時(shí),要定時(shí)對(duì)電刷高度和接觸情況進(jìn)行檢查,發(fā)現(xiàn)問(wèn)題及時(shí)排除,否則會(huì)造成起動(dòng)機(jī)損壞。3、電磁開(kāi)關(guān)觸點(diǎn)接觸不良、單向

柴油發(fā)電機(jī)組啟動(dòng)馬達(dá)損壞的原因可能有以下幾種:
1、啟動(dòng)時(shí)間過(guò)長(zhǎng),沒(méi)有按規(guī)定時(shí)間(約5s~10s)使用起動(dòng)機(jī),長(zhǎng)時(shí)間在未查明原因情況下連續(xù)啟動(dòng)起動(dòng)機(jī)。
2、當(dāng)電刷磨損到原長(zhǎng)1/2時(shí),應(yīng)更換電刷。在維護(hù)起動(dòng)機(jī)時(shí),要定時(shí)對(duì)電刷高度和接觸情況進(jìn)行檢查,發(fā)現(xiàn)問(wèn)題及時(shí)排除,否則會(huì)造成起動(dòng)機(jī)損壞。
3、電磁開(kāi)關(guān)觸點(diǎn)接觸不良、單向齒、飛輪齒損壞。打鐵線打鐵不良等等都會(huì)造成起動(dòng)機(jī)故障。
4、啟動(dòng)馬達(dá)定子繞組短路、換向片損壞或者電刷粉塵造成短路、電樞局部短路、電刷磨損嚴(yán)重導(dǎo)致的接觸不良、馬達(dá)軸承磨損嚴(yán)重或者裝配軸心線不直,轉(zhuǎn)子拖殼、齒輪或皮帶輪破裂等,其中一項(xiàng)出現(xiàn)問(wèn)題都會(huì)造成馬達(dá)無(wú)法啟動(dòng)。
啟動(dòng)馬達(dá)損壞的常見(jiàn)癥狀有:
1、啟動(dòng)時(shí)無(wú)轉(zhuǎn)動(dòng)或轉(zhuǎn)動(dòng)緩慢。
2、啟動(dòng)時(shí)有異響。
3、啟動(dòng)時(shí)馬達(dá)發(fā)熱。
4、啟動(dòng)時(shí)電流過(guò)大。
5、啟動(dòng)無(wú)力。

There may be several reasons for damage to the starter motor, including:

1. The starting time is too long, and the starter is not used according to the prescribed time (about 5-10 seconds). The starter is continuously started for a long time without identifying the cause.

2. When the electric brush wears down to half of its original length, it should be replaced. When maintaining the starter motor, it is necessary to regularly check the height and contact of the electric brush, and promptly eliminate any problems found, otherwise it may cause damage to the starter motor.

3. Poor contact of electromagnetic switch contacts, damage to one-way teeth and flywheel teeth. Poor iron tapping and other issues can cause starter failure.

4. Short circuit of the stator winding of the starting motor, damage to the commutator or short circuit caused by brush dust, local short circuit of the armature, poor contact caused by severe brush wear, severe wear of the motor bearings or uneven assembly axis, rotor drag shell, gear or pulley rupture, etc., all of which can cause the motor to fail to start.

Common symptoms of damaged starter motors include:

1. No rotation or slow rotation during startup.

2. There is a strange noise when starting.

3. The motor heats up during startup.

4. Excessive current during startup.

5. Failed to start.
