Questionnaire For Elektromag Thrustors
The "ELEKTROMAG" Thrustor is a device which converts electrical energy into linear mechanical force by its smooth, gental thrust.
The high efficiency off these thrustors make them ideal for a wide variety of general industrial applications such as brakes, thrust motions is machine tools,shutter damper operations, safety devices, actuation of levers, closing the electrodes of spot welding machines, for power processes, operating sliding doors, latches, hopper gates, control valves, transfer mechanisms of conveyors etc.The thrustors enable easy installation as they have only to be electrically connected. The thrustors are particularly adapted for those applications where they are to be frequently operated and are unaffected by these heavy duties because of their robust construction and dust exclusion seals for use in dusty atmospheres. The thrustors economise on muscular effort while saving time, money and labour.
The Electro Hydraulic Thrustor consists of a cylinder filled with oil and
having a centrifugal pump at the bottom of the cylinder. The centrifugal
pump is driven by a 3 phase fractional horse power class `B' insulated,
continuously rated rotor and stator. The specially designed radial impeller
permits operation of the pump in either direction of rotation. The rotor
and stator is mounted on top of the oil cylinder. The Thrustor is suitable
for 720 switching operations per hour. Thrustors confirming to IP-55 and
adjustable time lag on both up and down stroke can be supplied at extra
cost.
Consist of a cylinder filled with oil, the centrigugal pump located
at the bottom and the electric motor assembled on the top cover of the
cylinder. The rotor shaft of the motor is extended vertica
The thrustor exerts a thrust of 9/18 kgs. with a stoke of 50mm. The thrustor
motor is totally enclosed, 'B' class insulated, suitable for 3 phase, 440
volts A.C. 50 cycle supply system. The top bearing of the motor is grease
lubricated and the bottom bearing splash lubricated from oil in the tank.
Consist of cylinder, field with oil, having its centrifugal pump located
at the bottom at the electric motor assembled on the top cover of the
cylinder. The rotor shaft the motor is extended vertically downwards into the
cylinders and carries an impellers at it lower end. Inside the cylinder,
above the impeller is piston with two thrust rods connected by a cross bar
which delivers the useful thrust. When the motors drives the impeller,
pressure is builtup under the piston which moves upwards. when the impeller
stops, the load forces the piston down, the oil than bypasses the piston.
The rated stroke can be changed by altering the sleeve length on the
thrust rods inside the cylinder limiting the piston travel.
The thrustor motor is totally enclosed, 'B' class insulated suitable for
3 phase, 440 volts A.C. 50 cycle supply system. The top bearing of the
motor is grease lubricated and the bottom bearing splash lubricated from
oil in the tank.
FLAME PROOF THRUSTORS certified by CMRS, Dhanbad Gas I, IIA, IIB and IC
can also be supplied.
