6AM-ARV-54 spot supply GAST pneumatic motor

The American GAST pneumatic motor is a pneumatic actuator that performs continuous rotational motion, using compressed air as the working medium

The prime mover of quality is a dynamic device that uses the expansion effect of compressed gas to convert pressure energy into mechanical energy

Power device. Its function is equivalent to that of an electric motor or hydraulic motor, which outputs torque and drives the actuator to rotate

exercise The widely used pneumatic motors in pneumatic transmission are blade type, piston type, and gear type.

Mainly composed of: motor housing, connecting rod, crankshaft, piston, cylinder, valve, etc. compressed air

Enter the valve core to rotate it, and at the same time, use the valve core to rotate to sequentially send compressed air into the surrounding area

In each cylinder, due to the expansion of compressed air inside the cylinder, the piston connecting rod and crankshaft are driven to rotate. When

When the plug is pushed to the "bottom dead center", the valve core also rotates to the first exhaust position. Expanded gas

It is discharged directly from the cylinder through the exhaust port of the valve. At the same time, all remaining gases in the piston cylinder are self prepared

The exhaust port of the valve core distribution valve is discharged, and through this reciprocating cycle, the crankshaft can continuously rotate.

Its main source of work comes from gas expansion work.

The working principle of GAST blade pneumatic motor

The working principle of the bidirectional blade pneumatic motor is shown in the figure. Compressed air is input through hole A, small part

The slots on the sealing covers at both ends of the stator enter the bottom of the blade (not shown in the figure), and the blade is pushed out to make it

Tightly attached to the inner wall of the stator, most of the compressed air enters the corresponding sealed space and acts on the two blades.

Due to the unequal extension length of the two blades, a torque difference is generated, causing the blades and rotor to rotate counterclockwise

The gas after rotating and doing work is discharged through hole B on the stator. If the input direction of compressed air is changed (i.e

Compressed air entering through hole B and exiting through hole A can change the direction of rotation of the rotor.

Although various types of air motors have different structures and working principles, most air motors have

It has the following characteristics:

1. It can have stepless speed regulation. As long as the opening of the intake valve or exhaust valve is controlled, it controls the compressed air

By adjusting the flow rate, the output power and speed of the motor can be regulated. This can achieve the purpose of adjusting the speed and power.

2. It can rotate forward or backward. Most pneumatic motors only require a simple control valve to change the motor

The direction of intake and exhaust can achieve the forward and reverse rotation of the output shaft of the air motor, and can be instantly reversed.

During forward and reverse conversion, the impact is minimal. One of the main advantages of air motor reversing work is that it has almost

The ability to instantly reach full speed. By using the control valve to change the intake direction, forward and reverse rotation can be achieved. real

The time for forward and reverse rotation is short, the speed is fast, the impact is small, and there is no need to unload the load.

3. Work safety, not affected by vibration, high temperature, electromagnetic, radiation, etc., suitable for harsh work

The environment can work normally under unfavorable conditions such as flammability, explosiveness, high temperature, vibration, humidity, and dust.

4. It has overload protection function and will not malfunction due to overload. When overloaded, the motor only experiences a decrease in speed

Low or stopped, when the overload is relieved, it can immediately resume normal operation without causing any mechanical damage or other malfunctions.

It can operate continuously at full load for a long time with minimal temperature rise.

5. It has a high starting torque and can be started directly with a load. Start and stop quickly.

Can start with load. Start and stop quickly.

6. The power range and speed range are relatively wide. Power ranging from a few hundred watts to tens of thousands of watts; The rotational speed can be adjusted from

Zero to ten thousand revolutions per minute.

7. Easy to operate and maintain. Pneumatic motors have a simple structure, small size, and weight

Light, high horsepower, easy to operate, and convenient to maintain.

8. Using air as a medium, there are no supply difficulties, and used air does not need to be treated and stored in a large area

Compressed air without pollution in the air can be supplied centrally and transported over long distances

Pneumatic motors are divided into two forms: unidirectional and bidirectional. For unidirectional pneumatic motors, simply open and close the air inlet to control the motor

Rotate and stop.

The bidirectional pneumatic motor has two air inlets and one main exhaust outlet. When the motor is working, if it enters through one intake port, the other intake port will enter

The air port is the secondary exhaust port. If the direction of motor rotation needs to be changed, simply exchange the position of the air inlet and the secondary exhaust port. Therefore

The selected control valve must have the above functions in order for the motor to work properly. It is recommended to use a three position four-way valve or a three position five way valve.

When arranging the pipeline, the diameter of the pipeline between the gas source and the gas motor (including pipeline accessories, control valves, oil mist devices, etc.) should be

It shall not be smaller than the minimum inner diameter suitable for the motor, and the pipeline shall not have serious throttling phenomena. The pipeline joints should be firm and tight

Seal and ensure no leakage, otherwise the pneumatic motor will not achieve the expected working performance.
