How to repair submersible mixer malfunction

Many customers will have some quality problems after using the submersible mixer for the first time, so how to overhaul the quality problems? Our technical personnel have made a detailed analysis according to some specific situations, please see the following.


1, submersible mixer gear box inspection submersible mixer gear box processing accuracy is high, heat treatment is good, but also flooded the gear teeth broken and gear shaft does not leave axial clearance phenomenon. The gear box was thoroughly cleaned and the gears, gear shafts and bearings were carefully checked. Found that the surface of the gear teeth smooth, no pitting, cross phenomenon, gear meshing side gap is normal, tooth profile no significant wear; bearing radial, axial clearance is normal, inner and outer ring and roller surface are no pitting freckles, the overall quality is good; axial clearance of the shaft is fair, hand disc output shaft, flow freely, no jamming phenomenon, and no abnormal sound. Therefore, exclude the fault of the gear box.


2、Inspection of mechanical seal of submersible mixer


The mechanical seal is the most easily malfunctioning part of the submersible mixer, often due to wear and tear to make the mechanical seal failure, the seal cavity into the water. We first decomposed the mechanical seal assembly, including two sets of mechanical seals, skeleton oil seal, output shaft, bearings, housing and end caps and other parts were cleaned and inspected, and checked the dimensions of the bearing housing and output shaft, no problems were found, indicating that the mechanical seal sector is intact, excluding the possibility of failure.
