The MVB-E and MVB-E-FLC flanged vibrator series have been designed for use in industrial processes with screens and sieves in environments with a potentially explosive atmosphere, caused by gas and dusts, in compliance with ATEX Directive (94/9/EC). These vibrators can be supplied in B, C, D versions according to the eccentric weights supplied with the vibrator and to be mounted by the user. In particular, these vibrators can be used in areas 1 and 2 (gas) and in areas 21 and 22 (dusts) according to the layout and the following features:
Three-phase voltage from 220V to 690V, 50Hz or 60Hz; suitable for use with a PWM inverter from 20Hz to the base frequency with constant torque load profile.
4 poles.
Low Voltage 2006/95/EC, ATEX 94/9/EC.
IEC/EN 60079-0, IEC/EN 60079-7, IEC/EN 61241-0, IEC/EN 61241-1, EN 60034-1.
The components that affect protection are 100% accurately controlled and recorded.
Continual service (S1) at maximum declared centrifugal force and electric power.
1500 Kgf. (14.7 KN), adjustable with variation of the eccentric weights.
IP 66 according to IEC 529, EN 60529.
IK 08 according to IEC 68, EN 50102.
Class F (155°C).
Standard with “drop by drop” trickle system.
From -10°C to +40°C, on request it is possible to have vibrators for max. ambient temperature +55°C. On request special greases for temperatures less than –10°C.
On demand with PTC rated thermistor heat detectors 130°C (DIN 44081-44082). Also on request thermistors with different temperatures and anti-condensation heaters.
In all positions and therefore without restriction.
All vibrators are 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. Insulated windings using “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. An external earthing screw is located on the casing as prescribed by Regulation IEC/EN 60079-0.
Constructed in spheroidal cast iron. 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.
Lamellar for clamped centric weight have an ample possibility of adjustment: the particular adjustment system adopted allows to obtain phase shift from 0 to 180° of the group of upper weights with respect to the group of lower weights and to have ample adjustment of the centrifugal force within the same group of weights.
Not envisioned in the MVB-E and MVB-E-FLC series.
Electrostatic surface treatment based on polymerised epoxy polyester powder in oven at 200°C. Tested in salt spray for 500 hours.
On request, corrosion high grade protection (stainless steel micro suspensions in a polyurethanic paint) is available.
