The SIROLL Fara Oiler Systems provided
by Siemens VAI offers the lowest possible capital cost
consistent with achieving the high quality requirements
of today‘s market place.
Conventional methods of oil handling are ineffective and
usually cause problems for coil processors. Excess oil,
caused by inaccurate over oiling, results in disposal
problems and can also interfere with coil handling. For
coil processors, the Fara Oiler System revolutionises
the oiling process by offering an efficient automated
method for the coating of aluminium or steel.
The SIROLL Fara Oiler electrostatic oiling
system applies oil lubrication accurately and
effectively improving the product quality, providing
rust protection and minimising oil wastage.
The base of the oiler is formed into an oil tank of 400
litres capacity and the internal base of the oiler slopes to
a drain area, where the oil is passed through a fine mesh
before being returned to the oil tank. The tank is equipped
with immersion heaters, located at the drive end. The heated
oil is drawn from the tank by a recirculation pump and
passed through a double pressure filter, to ensure that the
oil is completely clean prior to entry into the metering
pump.
Another advantage of the SIROLL Fara Oiler
system is that the heated oil tank within the spray
enclosure makes other heating unnecessary in environments.
At the drive end of the oiler an extended side wall provides
a surface, upon which are mounted, at low level, the double
filter, metering and recirculation pumps above a drip tray.
At a higher level, on the same surface, the high voltage
power supply is mounted in its own IP 54 enclosure and
adjacent are the pneumatic controls. Access into the oiler,
for maintenance and removal of the applicators, is through a
conventional door at the drive end, which is fitted with a
large viewing window.
Proven reliability has been achieved as a result of the sturdy construction and simple mechanical design for many years.
To avoid the need for extensive cross-site cabling, the electrical control enclosure has been mounted on the operator end of the oiling enclosure and incorporates the Siemens operator control/display panel. This end of the oiler does not have an access door, but is provided with a viewing window. The control system is based on a Siemens PLC which is entirely stand alone. Hard wired signals are required for inter-linking with line start/stop/speed signals or a customised profibus link-up can be provided as an optional extra.
