Safety monitoring systems
The
Atomizer is a key component in a spray dryer plant and, in order to
guarantee maximum operating safety under production, safety and
monitoring systems are available
- Sensors
for atomizer bearings temperatures
- Sensors
for motor bearings temperatures ( High Speed Motor)
- Air flow
sensor (High Speed Motor air cooled)
- Flow
switch sensor (High Speed Motor –Liquid cooled)
- Sensor for
atomizer vibration (accelerometer)
- Sensor for
spindle vibration (displacement)
- Sensor for
Rpm monitoring
- Sensor for
flooding alarm
- Sensors
for oil connections (if atomizer is oil lubricated)
- Oil
lubrication cycles (if atomizer is oil lubricated)
- Running
hour meter
The Local panel in stainless steel with safety electronics equipment is
supplied already wired, with analog, digital, relay outputs, ready to
be interfaced with customer system
Lubrication system
Lubrication
plays a very important role for a safe operation of the Atomizer.
When oil lubrication for atomizer bearings is required, CMT atomizers
are equipped with a separate automatic lubricator unit “minimal”
system.
A
very small amount of oil (few cubic mm x hour) is delivered to the
bearings through a low flow of compressed air.
The advantages of this
system are :
- Very
low oil consumption (from 200 to 500 cubic/mm hour) according to
atomizer’s size
- The
correct amount of oil delivered to the bearings guarantees optimal
friction reducing temperatures
- The
oil is not in the form of fog. No risk of ambient pollution
- The
low air flow preserves against contamination of bearings from dirty
- Oil
amount and time of cycle can be adjusted according to need
The
lubrication unit is controlled by an internal PLC :
- Low oil level alarm
- Oil delivery alarm
- Low air pressure alarm
- High air pressure alarm
An
internal vacuum pump (controlled by its PLC) removes the oil from the
atomizer sump.
A
system of seals prevent the oil leakage from atomizer.
