自上料攪拌車電機發熱的原因有哪些?

電機是自上料攪拌車的動力來源,電機的好壞也決定了自上料攪拌車是否可以長時間進行工作?;蛟S你在使用自上料攪拌車時遇到了,電機發熱的情況,是的,沒錯,自上料攪拌車工作時間久了,電機也會散熱,會出現發熱的情況,今天小編就帶大家來了解一下自上料攪拌車電機發熱的原因有哪些。
The motor is the power source of the self loading mixer, and the quality of the motor also determines whether the self loading mixer can work for a long time. Maybe you encounter the motor heating when using the self loading mixer. Yes, that's right. After working for a long time, the motor will also dissipate heat and generate heat. Today, Xiaobian will take you to understand the causes of the motor heating of the self loading mixer.
1、軸承工作不正常,必定造成電機發熱
1. If the bearing does not work normally, it must cause the motor to heat up
軸承工作是否正??蓱{聽覺及溫度經驗來判斷??捎檬只驕囟扔嫏z測軸承端判斷其溫度是否在正常范圍內;也可用聽棒(銅棒)接觸軸承盒,若聽到沖擊聲,就表示可能有一只或幾只滾珠軋碎,如果聽到有咝咝聲,那就是表示軸承的潤滑油不足,電機應在運行3,000小時~5,000小時左右換一次潤滑脂。
Whether the bearing works normally can be judged by hearing and temperature experience. The bearing end can be detected by hand or thermometer to judge whether its temperature is within the normal range; You can also use a listening stick (copper rod) to contact the bearing box. If you hear the impact sound, it means that one or several balls may be crushed. If you hear the hissing sound, it means that the lubricating oil of the bearing is insufficient. The motor should change the lubricating grease every 3000 ~ 5000 hours.
2、自上料攪拌車電機定、轉子之間氣隙很小,容易導致定、轉子之間相碰
2. Since the air gap between the stator and rotor of the motor of the self loading mixer is very small, it is easy to cause the collision between the stator and rotor
在中、小型電機中,氣隙一般為0.2mm~1.5mm。氣隙大時,要求勵磁電流大,從而影響電機的功率因數;氣隙太小,轉子有可能發生摩擦或碰撞。一般由于軸承嚴重超差及端蓋內孔磨損變形,使機座、端蓋、轉子三者不同軸心引起掃膛,很容易使電機發熱甚至燒毀。
In small and medium-sized motors, the air gap is generally 0.2mm ~ 1.5mm. When the air gap is large, the excitation current is required to be large, which affects the power factor of the motor; If the air gap is too small, the rotor may have friction or collision. Generally, due to the serious out of tolerance of the bearing and the wear and deformation of the inner hole of the end cover, the different axes of the base, end cover and rotor will cause chamber sweeping, which is easy to heat or even burn the motor.
3、電機的不正常振動或噪音容易引起電機的發熱
3. Abnormal vibration or noise of the motor is easy to cause heating of the motor
這種情況屬于電機本身引起的振動,多數是由于轉子動平衡不好,以及軸承不良、轉軸彎曲,端蓋、機座、轉子不同軸心,緊固件松動或電機安裝地基不平、安裝不到位造成的,也可能是機械端傳遞過來,應針對具體情況排除。
This situation belongs to the vibration caused by the motor itself. Most of it is caused by poor dynamic balance of the rotor, poor bearing, bending of the rotating shaft, different axis of the end cover, base and rotor, loose fasteners or uneven installation foundation and inadequate installation of the motor. It may also be transmitted from the mechanical end, which should be eliminated according to the specific situation.
