WORKING PRINCIPLE
SA pumps are half
open impeller centrifugal submersible pumps,designed for
automatic and non-automatic use. The impeller,mounted on the
end of the drive shaft,consists of a rear disk and
blades,which are enclosed by the pump body cover. Fluid enters
the rotating blade channel via the suction strainer,which
forms the support base for the pump. Here the fluid moves
radially from the centre outwards,acquiring energy both in the
form of pressure and increased speed. When it leaves the
impeller the fluid is conveyed towards the volute. Here part
of the kinetic energy is transformed into pressure energy and
the fluid leaves the pump via the side opening machined in the
pump body.
pump installation and applications
As
portable electric drainage & irrigation devices,SA series
single-phase vertical submersible pumps with lower water input
are widely suitable for water cluster
boxes,farmland,industrial & mining
enterprises,construction sites,ship and family,and
characterized by less volume,light weight and convenient
operation etc.(the pump is fitted with a floating switch,so it
is possible to achieve the automatic control of start-stop
action under no one’s care.)single-phase capacitor-running
asynchronous or 3-phase asynchronous motor is equipped in this
pump and installed with a built-in thermal protector,and can
be automatically cut-off in the case of overheat or
overcurrent,thus assuring safe and reliable running under
worse circumstances.
