或許你在使用小型攪拌車時遇到了電機發熱的情況，實際上小型攪拌車工作時間久了，電機也會散熱，會出現發熱的情況，除此之外，小型攪拌車使用后電機嚴重發熱出現原因主要有以下兩種原因造成：

You may encounter the heating of the motor when using a small mixer truck. In fact, the motor will also dissipate heat after a long time of operation of a small mixer truck, which will cause heating. In addition, the serious heating of the motor after use of a small mixer truck is mainly caused by the following two reasons:

一、電機繞組熱量散發多，沒能及時通過外殼散發掉。

1、 The motor winding emits too much heat, which cannot be dissipated through the shell in time.

二、電機外殼散發熱量的能力較差。

2、 The ability of the motor housing to dissipate heat is poor.

這兩種因素都可能造成小型攪拌車的電機熱量太大而導致電機被燒毀。這兩種因素造成電機過熱其根本原因在于：

Both of these factors may cause the motor of small mixer to burn down due to too much heat. The root cause of motor overheating caused by these two factors is:

小型攪拌車電機繞組產熱太多，其根本問題是在于電機導線非純銅導線所導致的，純銅導線導電能力強，電阻小，因此產熱少，如果其他材質導線電機工作時電阻大產熱多；

The motor winding of small mixer produces too much heat. The fundamental problem is that the motor wire is not pure copper wire. Pure copper wire has strong conductivity and small resistance, so it produces less heat. If the wire motor of other materials has large resistance, it produces more heat;

小型攪拌車作業后電機外殼散熱能力差，根本問題在于外殼是非純鋁材質。合金鋁不但質量輕，而且散熱能力更強，采用其他材質作為電機外殼，散熱能力不如鋁材質。

After the operation of small mixer, the heat dissipation capacity of motor shell is poor, and the fundamental problem is that the shell is made of non pure aluminum. Alloy aluminum is not only light in weight, but also has stronger heat dissipation capacity. It uses other materials as the motor shell, and its heat dissipation capacity is not as good as aluminum.

出現這種情況怎么辦要怎樣解決呢？

What can we do to solve this situation?

1.如果在普通公路上混凝土攪拌車發動機出現了過熱，應該盡快地降低車速，把攪拌車駛到樹蔭下，或駛到相對比較涼快的地方，將攪拌車停下來。打開發動機罩蓋，讓發動機怠速運轉，等待發動機溫度逐漸恢復正常。

1. If the engine of the concrete mixer is overheated on ordinary roads, reduce the speed as soon as possible, drive the mixer to the shade of trees, or to a relatively cool place, and stop the mixer. Open the engine cover, let the engine run at idle speed, and wait for the engine temperature to gradually return to normal.

2.在攪拌車發動機水溫恢復正常之后，將發動機熄火。然后再等待一段時間，直到發動機的水溫充分地下降了之后，再檢查發動機的冷卻水量。這時發動機的冷卻水量大都嚴重不足。按著規定量把冷卻水補足之后，再檢查一下冷卻系統，確認沒有其他故障之后，可以起動發動機，繼續行駛。

2. After the engine water temperature of the mixer truck returns to normal, stop the engine. Then wait for a period of time until the water temperature of the engine drops sufficiently, and then check the cooling water volume of the engine. At this time, most of the engine cooling water is seriously insufficient. After replenishing the cooling water according to the specified amount, check the cooling system again. After confirming that there are no other faults, start the engine and continue driving.

3.如果在高速公路混凝土攪拌車出現了發動機過熱，須立刻把暖風全部打開并打開車窗，這時車廂內很熱很熱。由于有暖風幫助冷卻水散熱，能使冷卻水溫大幅度地下降。

3. If the engine of the concrete mixer truck on the expressway is overheated, you must immediately turn on all the warm air and open the windows. At this time, the compartment is very hot. With warm air to help cool the cooling water, the cooling water temperature can drop significantly.

電機是小型攪拌車的動力來源，電機的好壞也決定了攪拌車是否可以長時間進行工作，所以平日中使用要注意它的維護保養，更為詳細的事項就來我們網站http://www.www.boy7up.cn咨詢看看吧！

The motor is the power source of the small mixer, and the quality of the motor also determines whether the mixer can work for a long time, so you should pay attention to its maintenance in daily use, and more detailed matters will come to our website http://www.www.boy7up.cn Consult!
