GUIDED
VERSION ASEKO AERATION SYSTEM
Three footings (9)
to be used for each supporting tube with aerators (5)
are anchored to the bottom of the tank.
Two rope strands (8)
are led through the footings (9).
Each rope strand is fixed to one adjustable support (7)
of supporting tube, which is abutted to the bottom of the tank by the
tube. The supporting tube is tightened to the bottom of the tank with
the help of two rope strands. The guiding rope is pre-tensioned and both
ends of its strands are fixed to the upper part of the tank with the help
of a clamp (10).
Air distribution pipeline, against the axis of supporting
tubes, is aligned by couplings with external thread and horizontal axis.
Air is transferred to each supporting tube by means of spherical valve
(3), disconnecting
screw joint (2)
and coupling hose (4).
The spherical valve and disconnecting screw joint shut off air transfer
and disconnect the coupling hose when supporting tube is removed from
the tank.
Removal of supporting tube out of the tank is performed in the following
way :
After releasing the fastening of the guiding rope in the fixture, the
supporting tube floats up due to hydrostatic pressure. Then the supporting
tube can easily be removed by hand. To reverse this procedure, the supporting
tube should be placed on water level and pushed back to the bottom with
the help of both ends of the strand. The strands are again fixed to the
fixture.
Each supporting tube is equipped with a mechanism to drain condensed water
from the air. A small tube is connected to the bottom of the supporting
tube from the drainage cap (1)
through the connecting tubing (4).
After opening of drainage cap and with the system operating fully , internal
air overpressure discharges the condensed water from the supporting tube
above the water level.
The guided version ASEKO aeration system is intended for tanks accessible
from one side (one sided installation) and for large tanks accessible
from two sides (two sided installation).
Mounting is executed into empty tanks. The supporting tubes are levelled
by adjustable supports. The flatness of the bottom is secured in this
way and any possible surface irregularity is eliminated.
Removal and reassembling of individual supporting tubes for the purposes
of checking or repair can be performed under full operation of the system
without stopping the work or interruption of pumping.
The supporting tube preserves entirely its original level after it is
removed and installed back to its original position. Removal is performed
manually (2 operators) without any hoisting device.
