Dalian Empire Shield Pump
Thread Content
The radial and axial displacements are both fine during operation. Why does the radial displacement increase when the flow rate is raised? I seek advice from experts
What is the designed flow rate of the pump, and what is the current flow rate under operation?
Normal is 160 cubic meters per hour. After reaching 100, the radial displacement begins to increase
I have only seen shielded pumps equipped with axial displacement probes; I have never seen any equipped with radial displacement probes.
There’s a problem with the displacement gauge; it changes with current (flow rate). Is it a newly designed gauge? It seems they didn’t pass the assessment
Was it resolved later? What exactly causes it?
If the noise and vibration of the pump are normal, it may be that the TRG gauge isn’t set properly; there are 4 DIP switches – check the signal cutoff setting
Before leaving the factory, the axial displacement is set according to the rated flow rate and head; as the outlet flow rate and pressure change, the axial displacement also changes, and re-adjustment is required – contact a professional manufacturer at 15242535301
