15 kW motor blades do not rotate.

The working principle of vane pneumatic motor is similar to that of hydraulic motor. Compressed air enters from the transport crowd. Blades acting on both sides of the working chamber. Due to the eccentric installation of the rotor, the torque difference caused by the air pressure acting on the blades on both sides makes the rotor rotate counterclockwise. When the eccentric rotor rotates, the volume of the working chamber changes, which generates pressure difference on the blades of adjacent working chambers to drive the rotor to rotate. The gas after doing work is discharged from the output port. If the input direction of compressed air is changed, the rotation direction of the rotor can be changed.

The main reasons why the vane pneumatic motor does not rotate are as follows:

1, foreign matter mixed into the motor;

2, the blade is broken, broken;

3, bearing rust;

4. Locking between rotor and cylinder head.

The solution is as follows:

1, remove foreign bodies inside the motor;

2. Clean the damaged blades inside the motor and replace them with new ones; If the bearing is rusty, replace the bearing of the same model; The rotor is generally stuck to the lower cylinder cover, and it is common to readjust the gap between them. The gap between them should be as small as possible and keep friction-free.

In addition, not only the motor can't work without turning, but also the torque of the pneumatic motor is not enough, which leads to the following reasons: (1) the blades are seriously worn; The cylinder is badly worn; The upper and lower covers of the cylinder are seriously worn; Bearing embroidery or rail wear; Insufficient intake air flow or foreign matter blocking the air inlet filter screen; Can't meet the work pressure; Excessive wear or fracture of impact rod and impact block; Lack of lubricant, etc.
