Analysis on the Reason of Low Speed of Stainless Steel Fountain Pump

Stainless steel fountain pump speed is too low for the following five main reasons:
1, belt wear. There are many large-scale from the pump with a pass, due to long-term use, belt wear and loose, there is a slippery phenomenon, thereby reducing the pump speed.
2, man-made factors. A considerable part of the user due to damage to the original motor, casually coupled with another motor drive, resulting in a small flow, the head is low or even the consequences of not pumping water.
3, improper installation. The two pulley center distance is too small or the two axes are not parallel, the belt is tightly mounted to the top, so that the angle is too small, the two pulley diameter calculation error and the coupling shaft pump two axis eccentricity distance, etc. will cause Change of pump speed.
4, the pump itself mechanical failure. Impeller and pump shaft fastening nut loose or pump shaft deformation bending, causing the impeller to move more directly with the pump friction, or bearing damage, are likely to reduce the pump speed.
5, power machine repair does not record. If the motor is burned out due to the windings, the change in the number of windings, the wire diameter, the wiring method, or the failure of the maintenance failure in the maintenance of the windings, the pump speed will be changed.
