Specifications of vibrators MVSI-TS
The MVSI-TS series, obtained directly from the MVSI series, is characterized by the split weight covers. The weight cover is divided into two halves that can be removed in a radial direction. According to requirements it is possible to mount one or two split weight covers. The MVSI-TS series is indispensable in those applications where the position of the vibrator in the vibrating machine makes it difficult to axially remove the weight cover, while it has space to carry this out in a radial direction. The MVSI-TS series complies with the most recent IEC and EN international standards for use in atmospheres with potentially explosive powders. In particular, the MVSI-TS series can be used in areas 21 and 22.
Three-phase voltage from 48V to 690V, 50Hz or 60Hz; suitable for use with an inverter from 20Hz to the base frequency, with constant torque load profile.
4, 6 and 8 poles.
Conformity with European Directives
Low Voltage 2006/95/EC, ATEX 94/9/EC.
EN 60034-1, IEC/EN 61241-0, IEC/EN 61241-1
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.
Range extended up to 25000 Kgf. (245 KN), with centrifugal force adjustable from 0 to 100%.
IP 66 according to IEC 529, EN 60529.
Protection against mechanical impacts
IK 08 according to IEC 68, EN 50102.
Class F (155°C), class H (180°C) on request.
Standard on all vibrators with “drop by drop” trickle system.
From -20°C to +40°C. Versions for higher or lower temperatures are available on request.
Vibrator thermal protection
Standard PTC rated thermistor heat detectors 130°C (DIN 44081-44082) from size 70, on request for smaller sizes. On request, thermistors with different temperatures and anti-condensation heaters.
Fixing of the vibrator
In all positions and therefore without restriction.
All vibrators are correctly lubricated in the factory and do not require further lubrication if used in normal operating conditions (”FOR LIFE” lubrication). In heavy duty operating conditions periodical re-lubrication may be applied.
Large fixed electrical connections. Special shaped terminals allow to fix the power supply cable, protecting it from loosening.
Three-phase asynchronous type. Designed for maximum starting torques and torque curves specific to vibrating machines. Insulated windings using the “drop by drop” trickle system with class H resin. The rotor is die cast aluminium.
In spheroidal cast iron to have high strength and optimal elasticity. Patented shape that improves heat dispersion and lowers normal working temperature at full load.
Constructed in cast iron (spheroidal or grey). The geometry of the flange transmits the load to the casing uniformly.
Custom made with particular geometry, especially designed for this vibrator, suitable to support both high radial and axial loads.
In treated steel alloy (Isothermic hardening) resistant to stress.
Allow continual 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 (patent N° MO98A000194), called ARS, prevents adjustment errors.
In aluminium alloy, dismountable to allow disassembly in a radial direction. On request vibrators can be supplied with 1 or 2 dismountable caps.
Electrostatic surface treatment based on polymerised epoxy polyester powder in oven at 200°C. Tested in salt spray for 500 hours.
Stainless steel protection
On request, corrosion high grade protection (stainless steel micro suspensions in a polyurethanic paint) is available.
