The rotational speed is the number of rotations per minute of the fountain pump shaft or impeller. Usually denoted by the symbol n, the unit for each minute (r / min). Fountain pump speed and other performance parameters are closely related to a certain speed, resulting in a certain flow, head, and corresponds to a certain shaft power, when the speed changes, will cause other performance parameters corresponding changes.
Fountain pump is designed according to a certain speed, so the power of the matching power in addition to the fountain pump operating conditions to meet the requirements, the speed should also be consistent with the fountain pump speed. Fountain pump impeller speed reduction caused by the reasons are:
1, the fountain pump itself mechanical failure. Impeller and shaft fastening nut loosening or pump shaft bending deformation, resulting in more impeller, direct friction with the pump, or bearing damage, are likely to reduce the fountain pump speed.
2, the motor maintenance efficiency is reduced. Motor winding loss due to the winding, and maintenance of winding turns, wire diameter, wiring method changes, or maintenance failure is not completely ruled out factors will make the fountain pump speed change.
3, man-made factors. There are some users of the motor with the original damage to the random drive coupled with another motor, resulting in a small flow, low head and not even the consequences of Sheung Shui.
4, the fountain Pump cavity clogging will be wrapped in debris, resulting in lower impeller speed.
Therefore, the majority of fountain pump users to understand the reasons for lower fountain pump speed, true and reasonable use of fountain pump. Can improve the failure efficiency of the fountain pump and fountain pump service life.
