Juice is everyone’s favorite drink, and nothing beats a sweet, sweet juice on a hot summer day. The juicer is an indispensable tool for making this summer delicious, but the juicer will not turn is a headache. The following small series will take you to understand the causes and solutions of the malfunction of the juicer.
After the power is turned on, the switch is turned on, and the product does not work. It may be that the juice collecting tray is not installed in place. The juice collecting tray is used to collect juice and divert the juice. If it is not installed, the juice cannot be collected and diverted to the correct position. Therefore, the juicer will not rotate when the machine detects that the juice tray is not installed. If the top cover is not installed in place, it may also cause the machine not to work. The above faults only need to install the juice collecting tray or the upper cover in place.
If there is an unpleasant smell in the first few times of use, this is generally not an abnormal phenomenon. This is due to the first use of the motor and the smell from the plastic. If there is still an unpleasant smell after repeated use, please send it in time. to the maintenance point for inspection.
If the juicer suddenly does not turn during use, it may be that the voltage is too low. Just check whether the voltage in your home is too low. It is also possible that the push rod is pressed too hard. In this case, loosen the material rod and press lightly. You can also stop it for 20 to 30 minutes and use it again. If it can be used, it is the temperature control protection of the motor. If it cannot be used, it is recommended to send it to a maintenance point for testing.
If there is no problem with all the above tests, but the juicer will not turn, it can be considered that the power supply has no electricity, the motor winding is disconnected, the carbon brush is severely worn, the governor is in poor or damaged contact, and the motor bearing is damaged. At this time, you need to check the fuse and power lead first, restore the normal power supply, and then check whether the internal wiring and wiring are broken. Then turn the motor shaft by hand, check the lubrication state and wear of the bearing, add lubricant appropriately or replace the worn bearing.
Then check the contact between the carbon brush and the commutator, clean the commutator and adjust the spring pressure of the carbon brush to make the carbon brush and the commutator in good contact; if the wear is serious, it should be replaced. Check the governor, if the contacts are not in good contact, they should be ground or replaced. Use a multimeter to check whether the motor has voltage. If there is no voltage, the fault is an electrical circuit breaker; if there is voltage, the power supply should be disconnected, and the motor winding should be checked. If there is an open circuit, it should be rewound and the motor should be replaced if necessary.
Abstract: No matter what kind of juicer is, there will be various failures due to various reasons in the process of use, the motor overheats, or the motor is simply not compared, and sometimes it will
Loud noise. So how should the juicer malfunction be repaired?
Juicer fault one: the motor does not turn
Reasons for the problem: no power supply, open circuit of the motor unit, severe wear and tear of carbon brushes, poor touch or damage to the adjustment circuit, damage to the motor bearing, etc. Troubleshooting: Check the warranty first
The fuse and power supply 51 line, restore the normal power supply, and then check whether the internal connection and wiring are broken. Then roll the motor shaft by hand, and check the lubrication state and wear condition of the bearing.
When adding lubricant or replacing worn bearings. Then check the contact condition of the carbon brush and the commutator, clean the commutator and adjust the pressure of the carbon brush spring, so that the carbon brush and the commutator are in good contact.
Good; if it is serious, it should be changed. Check the governor, if the contact is bad, it should be repaired or replaced. Use a multimeter to check whether the motor has voltage. If there is no voltage, it is
The problem is electrical circuit breakage: if there is voltage, disconnect the power supply, check the motor winding, if there is an open circuit, it should be wound from scratch, and the motor should be replaced if necessary.
Juicer fault two: motor overheating
Causes of the problem: the power supply voltage is too high; the motor winding is partially short-circuited; the bearing is severely lacking in oil, and the wear is severe; the feeding amount is too large or there is a lot of hard fruit. Problem solving: first
Take out too much or too hard fruit and see if it returns to normal. If the fruit feeding is normal, the working voltage should be measured.
Use a voltage stabilizer to step down; if the voltage is normal, write a small amount of grease to the bearing to replace the severely worn bearing; finally check the motor winding, if there is a short circuit, it should be rewound
Or change the motor.
Juicer Trouble Three: Lack of Pressure
The reason for the problem: the adjustment pressure of the safety valve is too low or the valve core is stuck; the steel ball of the pressure limiting valve is broken or the valve seat is worn; the pipe joint is loose or the kiln seal is damaged and oil leakage. Problem solving: first
To check the pipeline and each joint, if there is oil leakage, fix the joint or replace the seal; then properly increase the safety pressure, if it is found that the pressure cannot be increased, it means that the fault is in the safety
Full valve or limited pressure idle. Remove the safety idler for inspection. If the idler core is stuck, repair the valve core and the wide seat; then remove the pressure limiter net.
It should be replaced, and if the valve seat is worn, it should be reground.
Juicer failure four: lack of flow
Causes of the problem: the matching gap of the plunger pair is too large; the plunger or the plunger spring is broken; oil leaks at each joint;
The rate is reduced; the liquid level is too low, and the oil pump is sucked empty. Problem solving: first check the hydraulic oil, if the oil level is too low, it should be increased; then check whether there is any trace of oil leakage at each connection, and tighten the connection.
head, replace the seal. Then check whether the oil temperature is between 20 and 50 degrees Celsius. If the oil temperature is too low, it should be preheated. If the oil temperature is too high, it should be stopped for cooling. Final View Plunger Coupler
Replace the worn plunger pair and the broken plunger spring.
Juicer fault five: excessive noise
Causes of the problem: the bearing is seriously lacking in oil or damaged; the feeding fruit is too hard; the carbon brush gas commutator is poorly touched or the carbon brush is severely worn. Problem Solving: When Noise or Oscillation
If it is too large, the amount of fruit feeding can be reduced; if the fault still exists, the bearing should be inspected. When the bearing has significant movement or the ball breaks, it should be replaced;
Grease should be added; finally check the wear condition of the commutator and carbon brush, clean the commutator, regrind or replace the carbon brush.
When we encounter a juicer malfunction,
Don't panic, and don't fix it yourself. First of all, you need to figure out the cause of the fault, and then find it.
The maintenance method, if you repair it indiscriminately, it may get worse and worse. You can refer to the above content to repair the juicer, and the fault will be solved.
