叉車起動機損壞的原因有哪些?

來源:http://nukkadh.com/ 日期:2019-01-04 發布人:admin

  1.嚙合后發動機空轉。說明單向嚙合器打滑或損壞,減震繃簧折斷,轉子與定子擦碰,磁場線圈或電樞線圈繞組有局部短路等。

  1. Engine idle after meshing. It shows that the one-way mesher slips or damages, the shock absorber spring breaks, the rotor rubs against the stator, the magnetic field coil or armature coil winding has local short circuit, etc.
  2.運轉緩慢無力。除氣溫低,使潤滑油較稠、阻力大、蓄電池電容量缺乏之外,主要原因在發動機內部,可能因為軸承過松而使電樞和磁極碰擦、勵磁或電樞繞組有局部短路,電刷磨損過多,電刷繃簧壓力缺乏,線路接觸不良,使電刷接觸電阻過大,換向器表面燒蝕或臟污等。
  2. Slow and weak operation. Apart from the low temperature, which makes the lubricating oil thicker, the resistance greater and the battery capacitance scarce, the main reasons are that the internal bearings are too loose, which may cause armature and pole rubbing, excitation or armature winding to have local short circuit, brush wear too much, brush tension spring pressure lack, poor line contact, brush contact resistance too large, commutator surface ablation or dirt, etc.
  3.發動磁輪與飛輪磁圈嚙合不良。飛輪齒圈嚙合不良。飛輪齒圈變形、斷齒,安裝不妥使齒輪和齒圈中心線不平行,電磁開關吸鐵行程調整不當。
  3. The engagement between the starting magnetic wheel and the flywheel coil is not good. Flywheel gear ring engages badly. The flywheel gear ring is deformed and broken, the center line of gear and ring is not parallel due to improper installation, and the iron absorption stroke of electromagnetic switch is improperly adjusted.
  4.發動齒輪與飛輪齒圈咬死不脫開。齒輪表面粗糙而嚙合太緊,驅動裝置在發動機電樞軸上卡死以及電磁開關觸點燒結等。
  4. Start gear and flywheel ring bite to death. The gear surface is rough and meshing is too tight, the driving device is stuck on the armature shaft of the engine, and the contacts of the electromagnetic switch are sintered.
  5.發動機運轉不良及異響。假如發動機在冷、熱車時都不好發動,證明故障在其內部,熱車好發動,冷車發動無力,冷、熱車空轉都好,但嚙合后無力,一般是蓄電池存電缺乏。按下發動鈕,若發動機不轉,應敏捷松開,檢查有無冒煙和發熱現象。

  5. Engine malfunction and abnormal noise. If the engine is not good to start when it is cold or hot, it proves that the fault is in its interior, the hot car is good to start, the cold car is weak to start, and the cold or hot car is good to idle, but after meshing, it is generally lack of storage battery. Press the start button, if the engine does not turn, it should be swiftly loosened to check whether there is smoke and fever.
  起動機有異響有以下四種原因:
  There are four reasons for the abnormal noise of the starter:
  a、叉車驅動齒輪未嚙入齒環時起動機主電路現已接通,宣布打齒聲。
  A. When the driving gear of forklift truck does not engage the gear ring, the main circuit of the starter is now connected and the sound of teeth beating is announced.
  b、叉車驅動齒輪與飛輪齒環兩齒相頂時,起動機主電路現已接通,宣布打齒聲。
  B. When the driving gear of forklift truck and the flywheel gear ring are at the top of each other, the main circuit of the starter is now connected and the sound of teeth beating is announced.
  c、接通起動機開關后,起動機殼顫動,這是因為固定螺栓松動而形成的,應停機緊固。
  C. After switching on the starter switch, the starter housing fluctuates, which is caused by the loosening of the fixing bolt and should be stopped and fastened.
  d、柴油叉車在行進中,因驅動齒輪與飛輪相碰而宣布的打齒聲,這是因為驅動齒輪端面和端蓋緣之間的間隔不符合要求形成的,應調整端蓋上的定位螺絲。
  D. During the driving of diesel forklift truck, the announcement of gear beating due to the collision between driving gear and flywheel is due to the inconsistency between the end face of driving gear and the end cover edge. The positioning screw on the end cover should be adjusted.
