Hydraulic turbine slip problem
Thread Content
The hydraulic turbine was disassembled to replace the balance sleeve; no other components were replaced. After reinstallation and with the seal in place, it was found that the single-string displacement differed by 0.40 mm from that before disassembly ； The total stroke difference is not significant ； I would like to ask what causes the differences in the single-string measurement values? No other parts were replaced – is that why it doesn’t work?
The axial alignment has changed; check whether the thrust disc is in place
Do you suspect that the thrust disc isn’t installed properly?
So early,,:handshake
The balance disc sleeve of a hydraulic turbine is integrated, right? Replacing it with a new one requires readjustment anyway. Check to see if it is properly installed; if there are no issues with the installation, make the adjustments promptly.
