Explosion-proof Profile

Classification of zones

Areas subject to explosion hazard are divided into zones . Zoning is based on the presence time of explosive substances and probability of explosion . Information and specifications for classification of the zones are laid down in the following standards:
•  GB 3836 . 14, IEC/EN 60079- 10- 1 for gas atmospheres
•  GB 12476 .3, IEC/EN 60079- 10-2 for dust atmospheres
Furthermore, a distinction is made between various explosion groups as well as temperature classes and these are included in the hazard    assessment .

Depending on the particular zone and therefore the associated hazard, operating equipment must comply with defined minimum requirements regarding the type of protection . The different types of protection require corresponding measures to prevent ignition that     should be implemented at the motor in order to prevent a surrounding explosive atmosphere from being ignited .

-   Zone 1 can also be used in Zone 2.
-   Zone 21 can also be used in Zone 22.
2) Motors which are certified for gas or dust protection must not be used in hybrid mixtures! Hybrid mixtures: when explosive gas and dust atmospheres occur         simultaneously.
3) Ex tc motors are not approved for operation in environments containing conductive dust .

Application

The explosion-proof motors are often used in the following industries to prevent explosion hazards that result in serious injury to persons    and severe damage to property.
•   Chemical and petrochemical industry
•   Production of mineral oil and gas
•   Gas works
•   Gas supply companies
•   Petrol stations
•   Coking plants
•   Mills (e .g . corn, solids)
•   Sewage treatment plants
•   Wood processing (e .g . sawdust, tree resin)
•   Other industries subject to explosion hazards

Noise levels

The noise levels are measured in accordance with DIN EN ISO 1680
in a anechoic room . It is specified as the A-valued measuring-surface sound pressure level Lpfa in dB (A) . This is the spatial mean value of the sound pressure levels measured on the measuring surface . The     measuring surface is a cube 1 m away from the motor surface . The sound power level is also specified as LWA in dB (A) . Please find the  noise value in technical data table, the specified values are only valid for totally enclosed fan cooling (cooling method: IC411) motor with no load at 50 Hz with no load, and the tolerance is +3 dB . While motor operating 60 Hz with no load, the values are approximately +4 dB (A) higher.

Vibration

The rotors are dynamically balanced to severity grade A using a half key. Table below contains the effective vibration values for unloaded motors. Vibration grade B can be provided as option.

Construction and mounting type

Notes：
1) At outdoor application, the using of protective cover (option code H00) is recommended;
2) At out door application the protection of shaft again jet-water is recommended .

Bearing Assignment

1MT0013 series motors are supplied with the ball bearing as standard . These bearings are either of the sealed or regreasable type .

For FS80 ~ 160, the floating bearings are assembled; for FS180 ~ 355, floating bearing at DE, and fixed bearing at NDE assembled .

The standard bearing can endure a maximum cantilever force,  the increased cantilever bearing design (Option code: L22) should be considered .

As standard, FS80 ~ 250 motors are not with regreasing device, but re-greasing device (Option code: L23) can be configured for FS160~250 . FS280~355 motors with regreasable bearing and    regreasing device is configured as standard .

Grease life and re-greasing interval

For permanent lubrication, the bearing grease lifetime is matched to the bearing lifetime . This can, however, only be achieved if the motor is operated in accordance with the catalog specifications .

For motors which can be regreased at defined regreasing intervals, the bearing lifetime can be extended and/or unfavorable factors such as temperature, mounting conditions, speed, bearing size and mechanical load can be compensated .

Grease life (Horizontal installation)

280 ~ 315	2	3000 h
	4，6，8	5000 h
355	2	3000 h
	4，6，8	4000 h

Note:

1)If the coolant temperature is increased by 10 K, the grease lifetime and regreasing interval are halved .
2) 40000 h apply to horizontally installed motors with coupling output without additional axial loads .

When the motor runs outside of normal conditions, the bearing life will be reduced, such as the following conditions .
■  When motor runs beyond the rated speed, the increase of motor   vibration will result in the extra radial and axial force on bearing . This will reduce the life of bearing;
■  When the motor vibration increase due to the environment or
other equipment, the bearing also will endure more radial and axial force . This also will reduce the life of bearing;
■  If the coolant temperature is increased by 10 ºC, the grease lifetime and regreasing interval is halved .

5. If you need to use an armored gland, please make a special inquiry.

Electrical design

Rated Output
Beide Motors rated output powers means that the motor runs under continuous duty S1 (IEC 60034 - 1) operation when operated at     ambient temperature from - 15 ºC to 40 ºC and at altitudes of up to 1000 m over sea .
Voltage and Frequency
IEC 60034-1 differentiates between Category A (combination of voltage deviation ±5 % and frequency deviation ±2 %) and Category B (combination of voltage deviation %) and Category B (combination       of voltage deviation ±10 % and frequency deviation +3 % / -5 %) for   voltage and frequency fluctuations. The motors can supply their rated     torque in both Category A and B. In Category A, the temperature rise is  approximately 10 K higher than during normal operation.

Voltage deviation	±5 %	± 10 %
Frequency deviation	±2 %	+3 % / -5 %
According to the standard, longer operation is not recommended for Category B .
