Problems with the three-parameter probe for circulating water fans
Thread Content
Dear experts, for the three-parameter probes used in circulating water fans, we have traditionally used the KR939 series from Beijing Kere. Apart from this brand, are there any other manufacturers you are aware of? Imported or domestic products are both acceptable; the quality must be reliable and the items should not be prone to damage.
Three-probe systems are unreliable; they are often used in the gearboxes of cooling tower fans. It is recommended to use acceleration vibration probes, temperature measurement transmitters, and static pressure sensors for oil level monitoring. This approach requires slightly more investment, but it offers higher reliability and accuracy, as well as reduced maintenance needs in the long term.
However, the equipment does not meet the requirements for modification; there is only one three-parameter mounting hole on the gearbox. How can it be modified? Do you have any photos or diagrams? Thank you so much! !
With yours, are only the liquid level issues likely to arise, or are there other problems as well?
The liquid level is the most prone to problems; an interface can be found on the outlet line of the oil cup outside the impeller, and a differential transmitter can be added (since the gearbox functions like an open-container, it is sufficient to measure the pressure difference relative to the atmosphere).
It’s just that there’s an issue with the liquid level measurement; do you guys experience this as well? ?
Yes, the main issue is that the gearbox oil required by the manufacturer cannot be properly maintained or replaced. What was said on the 3rd floor is correct – modifying the liquid level level will make it work well
:Handshake, thank you! !
Thank you for the reply! ! :handshake
I often encounter situations where the level indicator goes offline or fails to give any indication. Could someone please advise me on how to modify it?
We are replacing the probe. . . . You can try installing a micro-pressure transmitter at the external sight glass
