Most Frequent Faults of Diesel & Petrol Generators
Nowadays in many spheresgenerators on diesel and gasoline fuel. The condition of the whole object depends on their serviceable and uninterrupted operation. In order for the devices to function fully, they, like any technique, need preventive measures for technical inspection. This avoids the majority of breakdowns and the need for repair work, especially with high loads and intensive work.
In the case of simple breakdowns, manymanage independently. If serious faults are found, their elimination should be entrusted to trusted specialists with the necessary experience, relevant knowledge and high qualification. More often serious failures of petrol and diesel power stations are a consequence of not eliminated earlier a problem.
strong> Self-inspection
Before you start, you need toindependent inspection of equipment. This recommendation applies to any installation. First of all, pay attention to the integrity of the generator housing. It is checked for cracks and other possible damage. This procedure is also carried out before the start of a poorly working or failed generator.
If the external condition of the case does not cause concern, you can run. In the event that there are no visible malfunctions, but the generator does not work well, the wiring fault may be the cause: poor condition of the contacts in the conductors or their complete absence.
If the diesel generator works, but it doesdoes not produce any tension, the malfunction may be hidden in brushes or contacts. Important point: when checking the status of any electrical part, it is necessary to completely disconnect the equipment. If after checking the brushes and contacts of the diesel power plant the situation remains the same, the problem may be a voltage regulator. Estimate the state of the stator of the generator and the winding of the rotor.
Understanding the causes of poor operation of diesel and , it is worth paying attention to a mechanical problem, which may be a defective bearing located in the lid of the generator.
A malfunction can be enclosed in the bearing itself(it could wear, it could jam or it crumbled), and also in its seat in the lid. The landing site could eventually develop, and this, in turn, leads to the fact that the rotor "sags". In the process of operation, a rotation occurs in which the active iron of the rotor and the stator will constantly rub, which will invariably lead to rapid wear.
If you inspect the device yourself, it will not be difficult to replace the generator parts such as the bearing and cover with your own forces.
strong> Diagnostic method
Unequivocally determine the causes of generator failureit is quite difficult, because they can be different. Only a very small part of the problems can be eliminated on their own. In most cases, this will require not only qualified specialists, but also professional repair equipment. In this regard, the best option will be a timely diagnosis, which will avoid subsequently serious problems. For diagnostic activities, there are certain time intervals that are associated with the clock that the generator has worked on.
A great experience of professional masters will allow to conduct a thorough check for any possible malfunctions, without missing any nuances, regardless of the capacity of the unit.
It should be noted that manufacturers forEach model of the diesel power plant is provided and the optimum frequency of testing is indicated. This can not be neglected, so that problems do not arise, leading to serious breakdowns.
By purchasing a diesel generator from a trusted and reliable supplier and trusting its installation to specialists, you can avoid a large number of failures arising from improper operation.
strong> Types of malfunctions
The most serious problem encountered during workdiesel and gasoline power stations, is the engine overheating. The reason for this in many cases is improper installation of equipment. For generators whose uninterruptible power system is not equipped with a special container or casing, the most important thing is to ensure full access to it. In addition, it should be noted that all fastenings of the conductive system should not be rigid.
Another serious malfunction, manifested in the process of the generator, is fuel overexpenditure. This is an unstable operation at low rpm, and a bad start at low temperatures.
In diesel power plants it is necessary to regularlyto replace the oils and check the condition of the coolant, which will avoid many failures. At the same time, consumables must be of good quality. Without a timely oil change or refueling, the generator simply does not start or will stall during operation. To check the oil level in the system, there is a special feeler gauge.
An important aspect is the purification of air andoil filter, it is also necessary to replace or clean the spark plugs, especially when the diesel power plant is in intensive operation. In the absence of a spark, the fuel mixture will not ignite.
It is necessary to periodically inspect the generator, for which no special knowledge or practical skills are required. At this time, you can identify dangling or poorly fixed parts.
Another very serious breakdown, involvingexpensive repair, is the winding of the generator. This is due to the connection to the power plant of equipment, the load of which is higher than the declared maximum in the passport.
