The self-priming sewage pump of stainless steel is an important tool for industrial chemical transportation and lifting fluid. The correct installation and use of self - priming sewage pump is an important way to improve the service life of self - sucking sewage pump. The following causes of vibration of stainless steel self - sucking sewage pump are analyzed and eliminated. The reasons for the vibration of self suction pump are as follows:
(1) manual turning difficulty: shaft bearing wear, bending units are not concentric touch the pump impeller shell.
Elimination measures: straighten the pump shaft, adjust or replace the bearing, reset the concentricity of the unit, and reset the clearance.
(2) the shaft of the pump is too large: the wear and clearance of the bearing and the neck are too large.
Elimination: repair shaft neck, adjust or replace bearing
(3) hydraulic imbalanced impeller unbalance self - suction pump individual impeller blockage or damage.
Elimination measures: reset the static balance and dynamic balance of the impeller to eliminate the clogging, repair or replace the suction pump impeller.
(4) the axial flow pump shaft power is too large, the water level is too low, the Inundated Depth of the impeller is not enough, the debris is wound on the impeller, and the damage degree of the pump cavitation is different and the impeller is defective.
Elimination measures: elevate the water level of the intake pool, reduce the height of the pump to remove the debris, and set up the fence, repair or replace the impeller.
(5) based on the weak stiffness of foundation of vibration or angle screw loosening or resonance.
The elimination of measures: strengthening the foundation; tighten the anchor bolts.
(6) the efficiency of the self-priming centrifugal pump unit decreased sharply or the efficiency of the axial flow pump unit decreased slightly, with the noise of cavitation.
