Mixing truck can not avoid such problems during the use of such problems, such as abnormal sound problem is more common, so how to check? We will carry out the corresponding inspection work from three aspects.
Motor failure performance of fully automatic agitator
Before disassembling the motor, run it in the air to find problems. Such as mechanical stirrer motor abnormal sound, vibration is very large; The shaft sleeve of the motor shaft of the mechanical stirrer emits a hissing sound, and the shaft extension temperature reaches dozens of degrees in less than 2 minutes of empty operation of the motor. The internal bearing inner ring of mechanical stirrer produces pear-skin pitting area due to pitting, and the surface is rough, dull and dull, and pitting holes can be obviously seen. Skeleton oil seal inner ring damaged; There are dark spots formed by "running circle" in bearing inner ring and shaft sleeve of mechanical stirrer and corresponding journal.
Mechanical seal assembly failure performance
Mixing truck is prone to failure is the mechanical seal part, often due to wear to make the mechanical seal failure, sealing cavity water. First decomposition of the mechanical seal assembly, including two sets of mechanical seal, skeleton oil seal, output shaft, bearing, shell and cover parts such as the cleaning check, and check the mechanical agitator and relevant dimensions of the output shaft bearing, such as have not found the problem, and explain mechanical seal parts in good condition, rule out the possibility of failure.
Gearbox failure performance
The gear box of some agitator equipment has high processing accuracy and good heat treatment. The gear box is thoroughly cleaned and the gears, gear shafts and bearings are carefully checked. It is found that the tooth surface is smooth, without pitting and mating phenomenon, the meshing backlash is normal, and the tooth profile has no obvious wear. The radial and axial clearance of each bearing is normal, and there is no spot etching on the inner and outer rings and roller surface. The overall quality is good. The axial clearance of each shaft is reasonable, keeping the output shaft of the disk, free of movement, no jamming phenomenon, no abnormal sound. Well, the gearbox can be ruled out.
The abnormal sound problem of the mixer truck should be checked in this way. The related content that is better handled is this. If you run the machine abnormally and you cannot find the problem, you can contact us on the website www.zkzsljbc.com to solve your doubts.
