Manual for Pneumatic loading arm

The swinging pneumatic motor drive unit is a driving device installed on the land loading crane tube. It is composed of a swinging pneumatic motor, a gear reducer, a worm gear transmission mechanism, and a special structure rotating joint. It can be operated manually in places with frequent operations to reduce personnel labor intensity;
Swing type pneumatic motor is an energy conversion device that converts the pressure energy of compressed air into mechanical energy. The pneumatic motor decelerates through a planetary gear reduction mechanism (with a reduction ratio of 1:40). The pneumatic motor consists of a valve distribution mechanism, a driving mechanism, a housing, a core shaft, a stator, and a pendulum. The pendulum is connected to the core shaft through a crank mechanism, and the housing of the planetary gear reduction mechanism is connected to the shell of the swing type pneumatic motor using internal angle bolts. The swinging pneumatic motor is equipped with a planetary reduction mechanism, which combines the two to form a low-speed swinging pneumatic motor. This increases the reduction ratio, increases the motor output rate, improves efficiency, and saves energy.
Swing type pneumatic motor has the following characteristics:
1. Infinite speed regulation is possible, as long as the size of the intake valve intake is controlled, the output power and speed of the swing pneumatic motor can be adjusted to achieve the purpose of adjusting the speed and power.
2. Capable of implementing positive and negative rotation speeds, swing type pneumatic motors use control valves to change the direction of the motor's intake and exhaust, achieving positive and negative rotation of the motor's output shaft, and can be instantly reversed. The impact of positive and negative rotation is small, and it can almost reach full speed capacity in an instant without unloading the load.
3. Job security, free from vibration, high temperature, radiation, etc., suitable for working in harsh working environment such as oil depot, chemical refining, flammable and explosive, high temperature, vibration, dust and other adverse conditions.
4. It has an overload protection function and will not malfunction due to overload. When overloaded, it only reduces the speed or stops. Once the overload is relieved, it can immediately resume normal operation without causing mechanical component damage or other faults. It can operate continuously under full load for a long time and with small temperature rise.
5. It has a high starting torque and can be directly started with load.
6. Easy to operate, maintain, and repair, with a simple structure, small size, light weight, and high horsepower.
7. Using purified air as the medium, there is no supply difficulty, and used air does not need to be treated. It is pollution-free when placed in the atmosphere, and compressed air can be supplied centrally and transported over long distances.
8. A swinging pneumatic motor is an internal rotation movement within a certain angle range, that is, it can swing within a 360 ° range within a certain angle.
9. Purified air source pressure 0.8Mpa, working pressure 0.3~0.8Mpa
