The table applies to Fuel oil 1
The suction line tables comprise theoretically calculated values where
pipe dimensions and oil low are adapted to prevent turbulent lows from
occurring.
Turbulent lows can result in pressure losses and noise in the pipework. A
typical pipe system usually comprises pipe runs with 4 bends, a non return
valve, a shut-off valve and a pre-ilter.
The total resistance of these items is such that it can be disregarded. In the
tables no run longer than 100 m is listed, as experience shows this not to be
required.
The tables apply to standard heating oil of normal grade merchantable
according to existing norms. When starting operations with an empty pipe
system, the pump should not be run without oil for more than 5 min.
The tables give the total suction line length in meters with a nozzle
capacity of 2.1 kg/h. Max. permissible pressure on the suction and return
lines is 2.0 bar. For a two-pipe system the Q
max
46 l/h pump capacity at 0 bar
applies.
