Precautions for Disassembly and Assembly of Diesel Generator Sets

Nowadays, diesel generator sets can be divided into two types, one is diesel generator set, and the other is emergency diesel generator set. The better diesel generator sets include Cummins diesel generator set, Shangchai diesel generator set, and diesel generator set generally requires What maintenance should be done? We will briefly introduce about the use and maintenance precautions of diesel generator sets:

1. General maintenance

In order to ensure the normal operation of the diesel generator set, there should be no accumulation of water, oil and dirt around it, and no corrosive gas, so as not to damage the winding insulation of the diesel generator set.

While preventing moisture and dust, care should be taken not to affect the normal ventilation and cooling of the diesel generator set. Always clean the dust and dirt in the vents and keep them unobstructed. The temperature of the cooling air should not be too low to avoid condensation on the windings and other conductive parts.

For diesel generator sets that stop running for a short time for some reason, the slip ring does not need to be wrapped for protection, but insulating cardboard, paraffin paper or asphalt paper should be placed between the brush and the slip ring to prevent the brush from being brushed on the surface of the slip ring. -Spots are formed on the surface.

If the machined surface of the diesel generator set is rusted due to oil or paint peeling off, it should be derusted in time and painted with anti-rust paint.

2. Precautions for disassembly and assembly

The disassembly and assembly method of the diesel generator set is roughly the same as that of the asynchronous motor. However, due to the heavy weight of the generator, care should be taken not to damage it during disassembly and assembly. When removing the end cover, be careful not to damage the stator coil protruding from the surface of the base; when removing the rotor, put cardboard between the stator and rotor of the motor to prevent damage to the iron core and windings. When tying the rotor with steel cables, The steel cable must not touch the rotor journal, phoenix fan, collector slip, and lead wire that changes hands. The place where the rope is tied must be padded with wood or rubber;

3. Drying of diesel generator set

The newly installed synchronous generator should generally be dried before operation. If the insulation resistance meets the requirements, drying may not be carried out, but the load within 24 hours of the start of operation does not exceed 50% of the rated capacity.

Dingbo Power was founded in 2006 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
