Causes And Solutions For Idling Of Fluoroplastic Magnetic Pump
When the rotation ring and static ring of the fluoroplastic magnetic pump are operating correctly, the liquid will effectively cool the heat generated by the friction between the end faces of the dynamic and static rings, thereby maintaining stable operation. Once running idle, the high-speed dry friction of the dynamic and static rings will generate extremely high temperatures, which will quickly cause damage to the following three components that are in direct contact with the mechanical seal.
How does the fluoroplastic magnetic pump run dry? How to reduce the occurrence of dry running:
1. The installation height of the magnetic pump exceeds its own cavitation margin height, the inlet water pressure becomes low, and the water inlet is blocked.
Treatment method: Reduce the installation height of the pump and ensure that the installation height of the pump does not exceed the cavitation margin height. Avoid cavitation.
2. After the liquid is pumped, there is no one on site to watch, causing the magnetic pump to run dry.
Treatment method: Install a "pump protector" or arrange for someone to watch.
3. The inlet filter is blocked and the liquid cannot enter the pump cavity for operation.
Treatment method: Replace and clean the filter, and the cross-sectional area of the installed filter should be more than 2 times the pipeline area.
4. There are too many inlet elbows.
Treatment method: Reduce the number of inlet pipeline elbows to less than 3, thicken the elbows, and allow transition flow to avoid right-angle elbows.
5. The pump head is too high when selecting the model. For example, the actual equipment only needs a 5-meter pump head, and the pump head of the pump is 20 meters or even higher. At this time, if the outlet valve is fully open, the pump flow rate will automatically increase, far exceeding the specified pump flow rate of the pump. When the pump flow rate exceeds a certain value, the pump will produce cavitation.
Treatment method: Select a fluoroplastic magnetic pump according to the working conditions, and its actual head flow rate is highly consistent with the head flow rate of the fluoroplastic magnetic pump itself.
In the actual application of fluoroplastic magnetic pumps, there are always various situations. When the magnetic pump is emptied, the five treatment methods introduced above hope to be helpful to everyone.
