VC 100 VACUUM SWITCH
|

|
USE
The vacuum switch is employed for emptying tanks, basins,
and whenever a liquid intake work is necessary. The slipping
of air into the suction pipe means that the liquid is
running off. By detecting this, the switch stops the pump
automatically and prevents any damage due to dry operations.
WORKING
The switch must be set up on the suction line of the pump,
where it can perceive the vacuum created by the pump during
its inta-ke work.
To operate the system, the lever must be pus-hed down
manually and held until the pump starts. The vacuum in
the suction line causes automatic contacts’ closing
with no further manual interventions on the lever. As
soon as the liquid supply is running dry, the vacuum in
the suction line begins to fail; the mechanism detects
this and opens the contacts. The ope-rating range - as
far as the distance between the switch and the suction
pipe end is concer-ned - is 0 ÷ 4000 mm. The mechanism
of the vacuum switch con-sists on a manual lever connected
with brass alloy surfaced contacts. The membrane is in
Piracriten EPDM rubber, oil resistant. The sturdy metal
case as well as the internal components of the switch
are galvanised to withstand long use and adverse operating
conditions.
