The submersible mixer may have quality problems after users use them. How to quickly repair it in this case? The submersible mixer supplier will analyze and introduce for you:
(1) Analysis and inspection of Submersible mixer gearbox:
We carried out a thorough cleaning and maintenance of the gearbox, and carefully inspected all gears, gear shafts, and mechanical bearings. It is found that the surface of the gear teeth is smooth, without pitting corrosion and intermingling, the gear meshing side clearance is normal, and the tooth profile has no obvious wear; the radial and axial clearances of each bearing are normal, and there are no pitting spots on the inner and outer rings and roller surfaces, and the overall quality is good; The axial clearance of each shaft is reasonable, and the output shaft of the hand plate can move freely, without jamming and abnormal noise. Then, the fault of the gearbox can be ruled out.
(2) Inspection, analysis and treatment of motor failure of submersible mixer:
Motor failure performance-submersible mixer supplier:
Before disassembling the Submersible mixer motor, run dry to isolate the problem. If the motor makes an abnormal noise and vibrates a lot; the shaft sleeve of the motor shaft makes a hissing sound, and the temperature of the shaft extension of the motor reaches tens of degrees within 2 minutes of idling, which is hot. The inner ring of the bearing has a pear-skin-like pitting area due to pitting, and the surface is rough, dull and dull, and pitting holes can be clearly seen; the inner ring of the skeleton oil seal is damaged; the inner ring of the bearing and the bushing and the corresponding journal has " The dark spots formed by running laps.
(3) Inspection of the mechanical seal assembly of the submersible mixer:
It is the mechanical seal part that is prone to failure. Often the mechanical seal fails due to wear, and water enters the seal cavity. We must first disassemble the mechanical seal assembly, clean and inspect the parts including two sets of mechanical seals, skeleton oil seal, output shaft, bearing, housing and end cover, and check the relevant dimensions of the bearing seat and the output shaft, such as No problem is found, indicating that the mechanical seal is in good condition, and the possibility of failure is ruled out.
