Explosion-proof asynchronous blown vertical electric motors of ВАОВ5К type are designed to drive oil booster pumps of НПВ and НПВ-М types, which operate in conditions of the moderate and cold climate, in places of operation where by production technology formation of explosive concentration of gases, vapor and dust is possible.
Electric motors are certificated in Russia; they have the certificate of conformity GOSTR and Ukrainian & Russian permits for their manufacture and application.
Explosion-proof version: 1ExdIIBT4.
Climatic versions: У1; УХЛ1 (the motors are made of materials for operation at the temperature up to minus 600С; fasteners are made of stainless steel).
Constructive mounting arrangement: IM 4011 – without feet, with flange on the frame, with one cylindrical shaft end; output shaft end is downward directed.
The motors are coupled with driving mechanisms by means of gear or elastic sleeve-bolt couplings. The motors are delivered with keys by GOST 23360 in full sets.
Cooling method: ICA0151 – motor case is made with pipes for outside air to pass. Outer and inner fans are placed on the motor shaft.
Protection degree: case and terminal box – IP54; housing of the outer fan – IP20.
Operating mode is continuous S1 from AC network, 50 Hz. Supply voltage of the motor is in accordance with GOST 183-74 – 6000 or 10000 V at a customer’s agreement.
Motor run is direct, it is realized both with rated voltage, and with mains voltage reduction during the start up to 0,8 Unom. The motors are rated for 1000 starts per a year; they enable two cold starts successively with interval between starts from 3 up to 5 min, or one hot start. Interval between the subsequent starts is not less than three hours; admissible quantity of starts per a day is up to three starts.
Constructional features: Motors ВАОВ5К have frictionless bearings manufactured by the firm SKF, Sweden. All electric motors of ВАОВ5K series in climatic version УХЛ1 are made with frictionless bearings with liquid lubrication in oil reservoirs without external oil circulation (in top and bottom bearing units). Oil reservoirs have remote-controlled electric heaters to heat oil at temperature below zero.
The terminal box has three power clamps and grounding clamps (inner and outer), it enables inlet of the armoured cable with copper or aluminum veins with dry bunching of cable conductors or filling with cable compound.
Winding of the rotor of electric motors for power up to 1000 kW is aluminium, and for power more than 1000 kW is copper. Insulation of stator winding is «MONOLITH-2» is made by technology of vacuum-pressure impregnation of windings by epoxide compound using insulants of heat-resistance class F.
Motors ВАОВ5К are equipped by temperature sensors for stator winding, bearings and oil in oil reservoirs. Sensors’ terminals are brought in the separate terminal box. On panels of the electric motor there are places for installation of sensors to control vibration level in three measuring planes.
The motor designation is decoded as follows:
В – explosion-proof
А – asynchronous
О – blown
В – vertical
5 – series
K – made in Novaya Kakhovka
ХХХХ – Rated power of the motor, kW
Х – Д – for voltage 10000 V
Х – Number of poles
ХХХ – Climatic version by GOST 15150
1 – Installation category by GOST 15150
