How to Check the Working Quality of Cummins Diesel Generator Governor

1.Maintain standards

The internal parts of the speed regulator are not allowed to be stuck during operation. The movement of various parts must be flexible, and the matching clearance between parts must meet the technical requirements.

2. Maintenance methods

(1) Inspection and maintenance of speed regulating rotor parts:

1) When the flying iron frame and bracket rotate, there should be no jamming phenomenon. The rotor bearing is not allowed to be too loose or blocked or burned out. Otherwise, new parts should be replaced.

2) When the wear of the inner end of the fly iron exceeds 0.3 minutes, it should be repaired by welding repair.

3) When the matching gap between the flying iron seat frame bushing and the telescopic shaft exceeds 0.22mm, the bushing should be replaced with a new one. After the bushing is pressed in, it should be hinged with the telescopic shaft to ensure the matching size with the telescopic shaft.

(2) Inspection and maintenance of speed control gear components. . The mating surface of the speed control gear sleeve is not allowed to have major scratches and eccentric wear. When the buffer spring is not equipped, the two should be able to rotate freely. If the buffer spring is found to be greatly deformed or damaged or broken during inspection, it should be replaced with new parts. When the buffer spring is in a free state, there should be a certain gap between the groups, and the gap between each piece should be less than 0.2mm. The transition arc and straight part of the assembled buffer spring should fit closely with the flange of the speed control gear and the shaft sleeve, and the contact length with the outer diameter of the bearing should be greater than half of the circumferential length.

(3) Inspection and maintenance of speed regulating spring. After removing the speed regulating spring, a visual inspection should be carried out. If damage, cracks or distortion are found, the spring should be replaced with a new one. If the elastic force of the speed regulating spring does not meet the technical requirements, it should also be replaced.

3.Technical requirements

(1) When the connecting pins and pin holes of the speed regulator are seriously worn and cannot be repaired, new parts should be replaced.

(2) When the wear amount of the fly iron bushing and pin exceeds 0.15~0.20mm, the bushing should be replaced with a new one or the pin with an enlarged size should be replaced.

(3) The weight difference between the two flying irons after repair should be less than 3g.

(4) The flying iron seat frame should be able to rotate flexibly relative to the bracket by its own inertial force, and the flying iron seat frame should be able to swing freely on the seat frame.
