1. How does the motor of soybean milk machine not turn?
1. The series motor in the machine is damp and short-circuit occurs in the coil.
Soybean milk machine motor does not turn the solution: replace the series motor.
2, the relay can not pull or foot break solution: replace the relay.
3. The continuous use time is long, resulting in the temperature of the series motor is too high.
Solution: Turn off the switch, suspend the use, and slowly cool the motor.
4. Improper use leads to water in the machine and partial short circuit of the computer board.
Solution: Use a hair dryer to dry the computer board and water inside the machine.
5. What is the reason why the soybean milk machine can only heat the motor? It is generally the relay or the motor is damaged.
Two, soybean milk machine machine repair but the motor does not turn how to return a responsibility?
Large number of people always say after the machine repaired in soybean milk machine maintenance, motor to rotate with the cleaning function of commissioning key, with full function of commissioning, and add water after the water boiled not dozen beans, we actually not directly add water in most of the soybean milk machine maintenance of commissioning, because after the water to boil does not produce bubbles, and most of the machines, there are two sensors, one is the water level detection, That is, the long inductive needle, one is the overflow detection electrode, that is, the short inductive needle, so we in the maintenance of the machine as long as we add soapy water in the water or a little dish soap machine can be carried out according to the program, then say the working process of the soy milk machine, Ladle injection water level sensing needle start signal were detected water level to the system board signal driven heating rod heating the water boiled with water boiling to produce more and more bubbles bubbles will rise with the bucket of water boil away when bubbles rise to come into contact with the defence overflow spill electrode electrode to signal to the mainboard immediately told state of water has been boiling at the same time to achieve overflowing pot mainboard immediately stop heating stick In the whole process of making soy milk, the above process will be repeated several times until the machine alarms.
This is, of course, only most of the models, quality goods of the sun some inside the water level detection needle machine is equipped with temperature sensors, this kind of machine can directly with water of commissioning, because of the water to boil after reaching a certain temperature, the motor can start playing, but now this model is less, because now the factory in order to save cost so useless flame state.
Three, soybean milk machine motor failure maintenance process
A soybean milk machine because after the water or electricity, the maintenance after the power part, fault, can heat motor does not rotate to repair and make uncertain, open circuit, heating plate of the relay will be responsible for the control, the motor by the bridge rectifier power supply, bridge rectifier by the bidirectional thyristor power supply, the bidirectional thyristor is triggered by single-chip microcomputer control light coupling, Test in fruit and vegetable juice gears (this will soon turn gear motor, heating plate don't have a job), the motor can rotate, motor and bridge rectifier is no problem, in short circuit the light coupling the output end of the 4 feet and 6 feet, motor can rotate, bidirectional thyristor is no problem, then analysis circuit, found that the optical coupling is low pull signal by single-chip microcomputer to control, Artificially pull the signal ground low, the motor can also rotate, indicating that the optocoupler is normal, and then detect the single chip microcomputer signal is high level at any time, detect the peripheral components did not find abnormal, determine the fault on the single chip microcomputer, can only replace the original factory computer board.
Four, soybean milk machine motor maintenance method: 1、motor maintenance：
Full automatic commercial soy milk machine, the principle is through high-speed collision cutting, to sand beans into fine soy milk. Due to the characteristics of the ultra-high speed motor, calorific value is big, so the commercial soybean milk machine equipped with motor forced cooling system, but because from the beginning to complete a soya-bean milk production need time is longer, the motor work is stopped working, due to the production process it is heated to boiling, so the heat is passed to the motor will also many, So in order to protect the motor, we suggest that after finishing the first time, let the soybean milk machine rest for a period of time, about 15-20 minutes, or add cold water to stir the key to stir once (it is better not to use this method).
2、knife group, mushroom and other vulnerable accessories maintenance：
The motor life of automatic commercial soybean milk machine is quite long, and the more likely problem is that the pulverizing system synthesized with the electric unit is easy to damage, because these accessories are loss-type accessories, but if you pay attention to maintenance in the process of use, the life can be greatly extended. Non-professional personnel had better not to remove these accessories, especially more than 20 liters of large capacity soybean milk machine, its knife set, mushroom head - two parts directly connected with grinding and cutting, proper maintenance can greatly improve the number of uses. And the damage to the two components is heat, so the choice of maintenance is the best way to let the soy milk machine stop working for 15-20 minutes to cool down.
