The enclosure of the CDX vibrators is characterised by
increased thickness and joints to prevent the transmission of an internal
explosion to the surrounding area.
Power supply Three-phase voltage from 24V to 690V (limit at
600V for UL and CSA certifications), 50Hz or 60Hz, or single-phase 100-130V
60Hz and 200-240V 50Hz; suitable for use with a PWM inverter from 20Hz to the
base frequency with constant torque load profile. Polarity 2, 4, 6 and 8 poles.
Conformity with Standards and Regulations ATEX Directive 2014/34/UE; EN/IEC
60079-0, EN/IEC 60079-1, EN/IEC 60079-31, UL 674-886, CSA C22.2. See also
tables. Controls The components that affect protection are 100% accurately
controlled and recorded with traceability. Functioning Continual service (S1)
at maximum declared centrifugal force and electric power. Intermittent services
are also possible depending on the type of vibrator and the operating
conditions. For detailed information, contact our technical assistance office.
Centrifugal force Range extended to 22400 kgf. (220 kN), with centrifugal force
adjustable from 0 to 100%.
Mechanical protection IP66 according to IEC/EN 60529.
Protection against mechanical impacts IK 08 according to IEC/EN 62262.
Insulation class Class F (155°C). Tropicalization Standard on all vibrators,
with vacuum encapsulation up to size 35, with “drop by drop” trickle system for
larger sizes. Ambient temperature From -20°C to +40°C. See also approval table
for other ambient temperatures. Vibrator thermal protection With thermal
protector at 130°C for the entire CDX range, or on request with PTC thermistors
rated heat detectors 130°C. Fixing of the vibrator In all positions and
therefore without restriction. Lubrication All vibrators are lubricated in the
factory and do not require further lubrication at start-up. Terminal box Large
terminal box to facilitate electrical connection. The terminal cover, with
increased thickness, is constructed to contain internal explosions. Special
shaped terminals allow to fix the power supply cable, protecting it from
loosening.
Electric motor Three-phase and single-phase asynchronous
type. Insulated windings using vacuum encapsulating up to size 35; using the
“drop by drop” trickle system with Class H resin for the larger sizes. The
rotor is die cast aluminium. Casing In high-tensile aluminium alloy up to size
30, in spheroidal cast iron for larger sizes. Bearing flange In spheroidal or
grey cast iron. The geometry of the flange transmits the load to the casing
uniformly. Bearings Custom made with particular geometry, especially designed
for Italvibras, suitable to support both high radial and axial loads. Motor
shaft In treated steel alloy (Isothermic hardening) resistant to stress.
Eccentric weights Allow adjustment of the centrifugal force. This adjustment is
realized by a graduated scale, which expresses the centrifugal force as a
percentage of the maximum centrifugal force. A patented system, called ARS,
prevents adjustment errors.
