The liquid alternately
entering and clearing the rotor buckets at high speed constitutes
a series of liquid piston that surge in rapid succession in and
out of the rotor buckets. Air enters through the inlet ports
of the cone which are located at the point where the liquid,
surges away from the rotor (A) and into the casing. Discharge
ports are at the point in the rotating cycle where the liquid
again surges back into the rotor buckets (B) permitting the compression
and discharge of the air. This effect is continuous and is repeated
thousands of time per minute, producing an un-interrupted air
flow without pulsation/vibration.
When the inlet is connected to closed system and the outlet to atmosphere
the machine will draw air and gases from the system and discharges
into the atmosphere and will act as Vacuum Pump. When the inlet is
connected to the atmosphere and the outlet to a closed system the machine
will draw air from the atmosphere and discharges into the system and
will act as Compressor.
The liquid ring acts not only as a piston to compress the gas/air but
also absorbs the heat produced due to compression friction and any
latent heat from vapour condensation occurring.
CONSTRUCTIONAL
FEATURES:
Body, Heads, Cones are made of close
grained heavy duty cast iron and rotor of spheroidal graphite(SG)
iron free from the cavities and blow holes. The shaft is made
of carbon steel and carries the only one moving part, the rotor
which is balanced for vibration free runing. The shaft is carried
on both the ends antifriction Ball/roller bearings which maintain
the close running clearence between working parts through out
the working life of the pump.
The Pumps can also be supplied with contact parts in phosphor bronze
and stainless steel of suitable grade.
The bearings of pumps are arranged for grease lubrication. The stuffing
box which prevents the leakage of gases and or air from the machine
to the atmosphere or vice versa is proportioned for efficient operation
by using a good quality packing rope. Replacebale shaft sleeves of
phosphor bronze/stainless steel are provided at the stuffing box portion
of the pump.
SPECIAL ADVANTAGES:
Premier
PV series vacuum pumps will have two inlet and four oulet flanges.
For normal operation two discharge flanges of any one side are
connected in parallel by outlet manifold and other side flanges
are blanked.
Due
to the twin inlets available the pump can be operated
as two independent vacuum pumps of half the capacity
at different vacuum levels.
Enhanced
capacity can be achived when handling saturated gas
by using inlet spray nozzles provided near the suction
flanges of the pumps.
Large
ports ensure liquid/particulate matter carried over
from the process can be handled without disruption.
The
rotor design improves efficiency; maximises capacity/speed
range and reduces noise levels.
