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:
1、 The motor winding emits too much heat, which cannot be dissipated through the shell in time.
2、 The ability of the motor housing to dissipate heat is poor.
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:
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;
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.
What can we do to solve this situation?
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. 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. 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.
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.zkzsljbc.com Consult!
