Countermeasures: You can find the manufacturer to replace.Countermeasures: Replace the upper and lower bearings and mechanical seals. Heating of the stator and rotor can also cause eccentricity. The damage of the upper bearing has little effect on the rotor. It is necessary to use precision instruments to detect and measure the bearing and shaft squatting.Countermeasure: Replace the bearing.
Here, the common causes and countermeasures of bearing damage and fracture of submersible sewage pump are summarized. Countermeasure: Replace the impeller. , The shaft will break. Cause analysis of common bearing damage and fracture of submersible sewage pumps.One, common reasons and countermeasures for damage caused by poor quality of water pump bearings. Shaft breakage caused by periodic vibration of the bearing.
Countermeasures: Turn on the impeller, remove garbage, and make the pump run under normal conditions. The shaft is broken due to the excessive impact of the return water in the pipeline. The distance between the inner ring and the outer ring of the bearing is too large, which is generally a quality problem caused during production. The rotor periodically vibrates. Countermeasures: Try to avoid heating the stator and rotor during maintenance.
Countermeasure: By adjusting the size of the check valve and the degree of valve opening, the pressure of the water hammer can be controlled to reduce the impact force received by the water pump. The impact of shaft grinding phenomenon on the rotor caused by the damage of the water pump bearing and the countermeasures.
Countermeasures: The above-mentioned problems can be Wholesale INA Bearing Suppliers corrected according to maintenance standards. The water pump rotor has a large amount of movement, and the bearing and shaft have a large amount of interference when they are in motion, resulting in left and right movement of the shaft. Shaft breakage caused by bearing damage.
