checkHigh power electric mixerFault analysis and handling
High power electric mixerThe stirring rod is made of stainless steel with excellent corrosion resistance. The angle of the stirring rod can be adjusted (0-30 degrees), making it easy to operate, smooth to run, and infinitely adjustable. It is particularly suitable for stirring large volume samples. It is a tool for petroleum, chemical, environmental protection, biochemical laboratories, analysis rooms, and education departments.
1. Inspection, analysis, and handling of motor faults in high-power electric mixers
The main faults of high-power electric mixers during operation are: before disassembling the motor of the electric mixer, the high-power electric mixer will idle to find out where the problem lies. If the abnormal sound emitted by the electric mixer is quite obvious, and there is an abnormal sound at the shaft sleeve of the motor shaft of the electric mixer, the temperature of the internal shaft of the high-power electric mixer will reach several tens of degrees Celsius in less than 2 minutes of idle operation of the motor of the electric mixer, which will be very obvious and hot. The inner ring of the bearing of the electric mixer has pear skin like pitting due to pitting, with a rough surface. The exterior of the electric mixer appears dull and dull, with visible pitting holes on the bearing; The inner ring of the bearing of the electric mixer will produce pear skin pitting areas due to pitting, and the surface of the electric mixer is rough. The inner ring of the skeleton oil seal in the electric mixer is damaged; The inner ring of the bearing in the electric mixer and the shaft sleeve in the electric mixer have dark spots formed by "running circles" at the corresponding shaft neck.
2. Analysis and Inspection of Gearbox in High Power Electric Blender
The gearbox of high-power electric mixer equipment has high machining accuracy and good heat treatment. The gearbox should be cleaned thoroughly and each gear, gear shaft, and bearing should be carefully inspected. The surface of the gear teeth in the electric mixer was found to be smooth, without pitting or interlocking, with normal gear backlash and no obvious wear on the tooth profile; The radial and axial clearances of each bearing in the electric mixer are normal, and there are no pitting spots on the inner and outer rings and roller surfaces of the electric mixer. The overall quality is good; The axial clearance of each shaft in the electric mixer is reasonable, and the manual output shaft can move freely without any jamming or abnormal noise. So, the fault in the gearbox of the electric mixer can be ruled out.
