After the diesel generating set is newly installed or overhauled, it needs running-in because the surface of the brand-new or repaired spare parts are not smooth, and if immediately used on the condition of high temperature, high pressure, high speed or full load, the spare parts will be seriously abraded, which will shorten the service life of the generating set. For this reason, the running-in use of diesel generating set is very important.
The running-in of the diesel generator set can be divided into two types: cold running-in and hot running-in.
1. Cold running-in
Cold running-in means that the diesel engine is operated on the testbed through the dynamo or other type of power to drive the bent axle, reaching the aim of the running- in of the linkage mechanism of the bent axle, valve timing mechanism and other clearance fit. In this process, engine oil with small viscosity should be used. In addition, conduct failure checking to the diesel generator set to see whether there is abnormal sound, scuffing of cylinder bore and air leakage.
2. Hot running-in
Hot running-in means that after installing and carefully checking the diesel engine, run the machine, and through zero-load and load test, further check and adjust the dynamo, making it have excellent dynamic property and economical efficiency. In this process, pay attention to checking the assemble condition of the spare parts and whether the gap between the mating parts are proper, whether the running of the dynamo is even and whether there is special sound in piston, piston pin, main bearing of the bent axle and connecting rod bearing.
The above is the relevant introduction made by Fuguang Machinery, hoping that everyone will have more knowledge on diesel generator set and on the operation and use of this machine.
