Adjusting the vacuum relief valve
The valve is pre-adjusted with a negative
pressure (18 kPa). If this is to be adjusted the
following procedure is used:
- Connect a manometer to the suction side
and measure with fully closed inlet.
- Shut down the pump and demount the
vacuum relief valve.
- Remove the damper cover (1) and measure
distance A.
- Loosen the locking nut (3) and adjust the
spring tension by turning the spring plate
(4). The compression of the spring (2) de-
termines the opening pressure. Changing
the distance A by 1.5 mm will give a cor-
responding change in pressure of 1 kPa.
- Remount the valve after adjustment and
test the pressure.
9. Inspect all cables and connections, repair if
neccessary.
10. Remount the protective panels, power up
the pump and give it a test run.
