FAULTS
Insufficient suction performance
Cause
Solution
Paragraph
Leaky suction duct
•
Check the connection on the suction side
and replace the seal if necessary
Maintenance / servicing
High operating
fluid temperature
•
Increase the flow of operating fluid.
•
Increase the fluid flow rate in the heat
exchanger
Installation manuals
Clogging of the
vacuum pump
•
Clean the liquid ring vacuum pump
and take corrective action if necessary
Maintenance / servicing
Squeaking (cavitation)
Cause
Solution
Paragraph
Suction pressures
too low
•
Connect the cavitation protection
•
Install a vacuum limiting valve when
operating in areas close to cavitation
Installation manuals
High operating
fluid temperature
•
Increase the flow rate of operating or
cooling fluid in the heat exchanger
Installation manuals
Abnormal operation
Cause
Solution
Paragraph
Operating fluid flow rate
too low
•
Adjust the operating fluid flow rate
Installation manuals
Loads on the pipe
system
•
Check the pipe connections
•
Check the connections of the pipes and the
operating fluid
Installation manuals
Air in the pipe
•
Chang the pipe routing
Installation manuals
