Most Frequent Faults of Diesel & Petrol Generators

Today, in many areas, diesel and gasoline generators are actively used. The condition of the whole object depends on their serviceable and trouble-free 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 case of occurrence of simple breakages, many cope independently. If serious faults are found, their elimination should be entrusted to proven 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 starting work, it is necessary to conduct an independent inspection of the 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 carried out and before the launch of a poorly working or failed generator.

If the external condition of the housing is not a concern, the diesel generator can be started. In the event that there are no visible malfunctions, but the generator does not work well, the reason may be wiring faults: poor condition of the contacts in the conductors or their complete absence.

If the diesel generator is running, but it does not produce voltage, the fault 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 reasons for the poor operation of diesel and gasoline generators, it is worth paying attention to a mechanical problem, which may be a faulty bearing located in the lid of the generator.

A malfunction can be enclosed in the bearing itself (it could wear out, it might wedge or it would crumble), and also in its seat in the lid. Landing place could eventually develop, and this, in turn, leads to the fact that the rotor "sags". In the process of operation, rotation occurs, in which the active iron of the rotor and 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

Unambiguously to determine the causes of generator failure 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 carry out a thorough check for any possible malfunctions, without missing any nuances, regardless of the capacity of the unit.

It is worth noting that the manufacturers for each model of the diesel power plant are provided and specified the optimal frequency of verification. 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 that arises in the operation of diesel and gasoline power plants 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 revs, and a bad start at low temperatures.

In diesel power plants it is necessary to regularly 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 replacement of oil 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 cleaning of the air and oil filter, as well as the replacement or cleaning of 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 failure, entailing an expensive 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.
