THRUSTOR DURING POWER STROKETHRUSTOR DURING MOTOR IS SWITCHED OFF

Introduction:

Working Principle:

Application:

Other Applications:

The “Electro Hydraulic Thrustor” is the device which converts input Electrical signal in to linear motion. Hence it's also called “Linear Actuator”. This system mainly consists of 3 Phase Electric motor, motor operated impellor, Oil (transformer oil) as a working fluid and a Piston. Hence this system can be divided in mainly two parts,1) Electric Motor and 2) closed loop hydraulic system. By simply providing electric power, smooth constant force in linear direction can be produced. This linear and jerk free thrust can be used to operate several mechanisms i.e. Thrustor operated brakes, door shutters, damping systems etc.

The impeller of the centrifugal pump driven by the motor generates a hydraulic pressure in the space under the piston. A hydraulic force is generated by the piston. Amount of force is dependent on Piston area and the pressure. Hence electrical power is converted in to the linier motion (of piston). Pressure is relived when motor is switched off (i.e. when there is the power failure). Piston comes at it's lower most position under the impression of counter weight or springs. (of mechanism on which Thrustor is mounted.)

One of the most common applications is the Thrustor operated Brake. In this application Thrustor is used to operate a Mechanical brake. Electrical power is used to rotate the impeller which in turn generates the hydraulic pressure by working on Oil hence to lift the piston. This smooth and jerk free thrust is either controlled by a appropriate stiff spring or counter weights of mech. brake. Brake shoes are operated by brake mechanism, which is operated by thrustor. Here Thrustor operated Brake acts as an important safety device.

Note:-

“EPL” make Electro Hydraulic Thrustors are almost maintenance free,

however for smooth and quick thrust, guide rods must be properly cleaned time to time.

While connecting thrustor to Mechanical brake, Pin joints must be lubricated enough for

free movement. Further if thrustor is installed under open atmosphere, proper covering of

thrustor is necessary to protect it from rain, dust and humidity.

Thrustor motors are totally enclosed but it's necessary to cover motor

portion if thrustor is installed in open atmosphere, to avoid damage from rain water. Motor

winding is of “F” class. Motor is designed for operating under 415 volts, 3 Phase and 50 Hz

Connections. For free and flexible movements, connecting wire must be at least 5 meters

in length. As thrustor function is independent of motor/impellor rotation direction, wires

can be connected in any sequence. How ever thrustor must not be turned ON without

filling oil of proper proportion for safety of motor.

Fill the thrustor with good quality transformer grade oil. Fill the

oil through upper oil filling plug until it over flows. For removing air (if any trapped ) , run the

upward and downward strokes manually for several times and if oil level decreases, fill the

oil until oil overflows. Oil once filled will last for long time, however when it's required oil can

be drained through bottom drain plug. While filling oil, thrustor must be held vertically.

Improper amount of oil in thrustor will cause to insufficient pressure head, hence shorter

stroke length. Ensure proper tightening of filling and draining plug after filling oil.

Thrustor are mounted vertically on Mechanical brake, however maximum

tilting of 10 degree is allowed while mounting. Thrustors are mounted on brake by means of

pivot pin. For proper functioning, pin must be lubricated with oil and rust free before using.

Installing procedure of the thrustor in various systems may vary case to

case, however for actuation of the thrustor only above mentioned electrical connection

is needed.

Motor of “EPL” make thrustor is totally enclosed and built with superior material under

strict stage inspections. “F” class Insulation is used, hence motor can run even in higher

ambient temperature.

Grease filled bearing is used in driving motor and splash lubricated bearing is used

in hydraulic system.

Oils seals are provided at the thrust rod. Time to time dust removal is recommended

from thrust rods to avoid wear of oil seal. A separate cover will work best in case of dusty

atmosphere.

An aluminum cast centrifugal impellor spins in oil and develops pressure head to lift

the piston, hence thrust of proper amount is generated.

All thrustors are provided with terminal box. Earthing stud is provided in the

terminal box.

However “EPL” make thrustors meet IP-55 standard, for long and maintenance free life

it's advisable to follow abovementioned instructions.


Thrustor Operated Industrial Shoe Brakes

ELECON PERIPHERALS LIMITED brakes are operated by “Electro Hydraulic

Thrustor” which is suitable for 415 Volts, 3 Phase AC supply, IP-55, Class - F.

OPERATION

In normal conditions i.e. When power supply is on, “Thrustor” is energized and it’s

piston will move upward (under the pressure developed by oil). Since the piston

rod is connected to link of brake such a way that upward movement of piston

and link will release the brake. When the power supply is ceased, in absence of

pressure head (of oil) piston will move downward and will pull the brake link such

a way that brake will be applied. Required braking pressure is generated by

compression spring, which is also operated by means of piston of thrustor and link

of brake. This operational feature makes Thrustor Operated Brake, an ideal

safety device.
