What items does Cummins diesel generator installation test?

The installation process of the generator is not simple. Nowadays, the installation and testing of the mainstream generator set are mostly implemented by the manufacturer. Generally, before installation, the surrounding environment should be kept clean, the position and size of the anchor bolt holes are correct, and the center line, elevation line and horizontal line are marked.

Generator installation test:

1. Alternator and diesel generator coupling, the parallelism and concentricity of the coupling are required to be less than 0.05mm, the actual use of requirements can be slightly lower, about 0.1mm, too much back to affect the normal operation of the bearing, resulting in damage, good coupling to be fixed with positioning pin. Retest the coupling before installation.

2. When the generator of sliding bearing is coupled, the height of the center of the generator should be adjusted to the center of your diesel engine slightly, so that the weight of the flywheel on the diesel engine will not be transferred to the generator bearing, otherwise the generator bearing will bear the extra weight of the flywheel, which is not conducive to the formation of the oil film of sliding bearing, leading to heating and even burning the bearing. The coupling of this type of generator should not carry any heavy objects.

3. When installing the generator, it is necessary to ensure that the cooling air inlet is unimpeded, and to prevent the hot air from entering the generator again. If there are shutters on the ventilation cover, the window should face down to meet the requirements of the protection level.

4. The mechanical coupling of single bearing generator should pay special attention to the uniform air gap between the stator rotor.

5. According to the schematic diagram or wiring diagram, choose the appropriate power cable, with copper joint to connect, copper joint and busbar, busbar and busbar fixed, the local gap at the junction is not greater than 0.05mm, the distance between the wires is not greater than 10mm, also need to install the necessary ground wire.
