(1)If there is a phenomenon that foreign objects
enter the pump delivery liquid (metal particles
and sand particles from the pipeline, etc.), a
filter should be installed at the suction end.
Filters should be cleaned regularly to prevent
clogging. Even if the liquid pumped by the pump is
clean, attach the filter the first time the pump
runs, because there are still some metal particles
and sand left in the pipe.
(2)If the weight of the suction or discharge
piping is applied to the pump, the alignment of
the pump may be damaged. At this time, take
support measures for the pipeline as shown in
Figure 2
(3)A check valve
following cases, that is, when the pipeline is
long, the actual pump head is high, the pump is
running
in
automatic
transported to a pressure storage tank, and when
multiple pumps are running in parallel. The check
valve should be installed between the pump and the
discharge valve.
(4)Install
an
unavoidably trapped. Exhaust valves should not be
installed in the parts where negative pressure
occurs in the suction pipe, because the valves
installed in such parts will cause air to be
sucked in.
(5)If there is a risk of water hammer, appropriate
measures can be taken, such as installing a quick
check valve.
(6)When the water pump is used for suction to a
high place, the end of the suction pipe should be
arranged at a depth of more than 2 times the pipe
diameter (D), as shown in Figure 2. And keep the
pipe ends 1 to 1.5 D or more from the bottom.
