Common trouble shooting and maintenance of small household crusher

Here I'd like to give you a brief introduction of some knowledge about home grinder and common troubleshooting methods, hoping to help you correctly understand and select this novel home machine In the practical application of small crusher, because of the use of ultra-high speed DC motor, the heat is also high The main heat generating parts are carbon brush, commutator and tank body In the electrified operation of this kind of motor, the carbon brush contacts the commutator surface, and the external power supply (usually DC excitation current) of the motor passes through the slip ring (on the rotor, With the rotor running), it is provided to the winding (excitation winding) of the rotor It plays the role of current commutation, so that when the rotor rotates, the incoming DC current will flow in from one end of the rotor, so that the motor rotates in one direction The carbon brush is in good contact with the rotor of the motor, and the connection between the carbon brush and the power supply provides electric energy for the rotor Because the carbon brush contacts with the commutator for a long time, there is wear When the length of the carbon brush reaches the extent that it needs to be replaced, the support spring behind the carbon brush will no longer work, which may cause poor contact between the carbon brush and the commutator, resulting in the situation that the pulverizer is powered on and does not start In case of these problems, as long as a new carbon brush is replaced, the rotor head can be cleaned with alcohol Solve In the practical application of the small crusher, the button switch will also cause the ablation of the internal power contact of the switch due to frequent stop When one of the internal contacts of the power switch is in poor contact, the crusher will not start again after pressing the button on the switch box again These problems can only be solved by replacing the switch box There are two ways to connect the power cord of the small crusher One is to have a 3-pin power cord jack on the power box of the crusher We only need to insert the special power cord allocated in the accessories of the crusher into the jack; the other way is to directly introduce the power cord into the power box of the crusher, so we don't have to worry about the looseness of one end of the power cord all the time Maintenance of small high-speed crusher: 1 Check whether the bearing is well lubricated; 2 Check whether all fasteners are tight 3 Check whether the drive belt is installed correctly and in good condition If the belt is damaged, replace it in time If there is oil stain on the belt or pulley, wipe it with a clean rag in time 4 Check whether the protective device is in good condition If the protective device is found to be unsafe, it shall be eliminated in time 5 Check whether there are materials or other sundries in the damaged cavity, and if so, remove them 6 Check whether the jacking head or jackscrew of the hydraulic jack is returned, and whether the adjusting gasket is installed correctly and tightly.
