Energy supply of private houses and critical infrastructure facilities may depend not only on central communication networks, but also on autonomous stations. The generator is one of the most demanded types of equipment in this class. It can be used both as an additional power source and as a backup unit in case of an accident. Gasoline units of this type are quite common on the market, but diesel generator sets (DGS) benefit from low fuel costs. There are other differences between these installations, but they should be considered separately.
Features of diesel generators
In the standard version, the generator has an internal combustion engine and an alternator. Unlike gasoline power units, diesel units provide fuel injection in the form of a fine fraction. Further, in the process of air compression, a multiple increase in pressure and temperature occurs, due to which ignition occurs. For this reason, it is not required to include spark plugs and batteries in the design, without which the same gasoline generators cannot do.installation. Diesel during the combustion process emits less scale and various impurities, which also contributes to an increase in the service life of parts and an increase in the environmental friendliness of equipment. It is also widely believed that in technological terms, gasoline vehicles in all industries are superior to similar devices using heavy fuel. However, in the case of generators, this is not entirely true, since the electronics unit of a developed model may include both automatic overload protection systems and sensors for monitoring current parameters.
Specifications of the units
The main performance indicator of any generator is power. Diesel units provide the highest power potential, so they are used not only for domestic needs, but also for maintenance of production workshops. The average characteristics of a diesel generator set in terms of power ratings range from 10 to 20 kW. But you can find models that fall outside this range. For example, to supply a small country house, it will be enough to purchase an 8 kW unit, and to supply large industrial facilities, 32-48 kW stations are purchased. The next significant characteristic of the DGU is the battery life, which depends on the volume of the fuel tank. For a modest private house, as a rule, there are enough small-sized installations that can operate continuously for 4 hours a day. For more demanding applications, you can also find generators that provide16 hour duty cycle.
Installation of stations
In the room where the generator is to be installed, there must be good ventilation, which will ensure the removal of exhaust gases. Fire safety measures should also be provided and the internal elements of the device should be protected from moisture penetration. It is necessary to put the equipment on a flat and stable surface, since oil should not leak during operation. As for the area of \u200b\u200bthe room, the optimal value would be 10-12 m2. This is enough for the installation to be removed from the walls at the required distance. If a containerized diesel generator set is purchased, it can also be placed outdoors. Such models are distinguished by the presence of a durable metal frame, as well as mineral wool insulation. The walls and lid of the container act as protection against external influences, but the requirements for structural stability remain the same.
Performance requirements
To ensure optimal performance of the unit, it is necessary to stock up on a small set of consumables and accessories. To begin with, automation devices and a network unit should be provided. In the first case, we can talk about refueling systems that independently fill the fuel tank using sensors. The most advanced stations also provide the ability to control the operation parameters via a computer. The network unit, in turn, is required for the automatic transition of the generator from the standby state to the active mode.work. A few minutes after the emergency shutdown of the main power, the power supply is started by generator sets. Diesel and oil are also mandatory components, without which the operation of the unit is indispensable. It is desirable to use diesel fuel without water and harmful impurities as fuel. A high-quality composition will allow you to extract maximum power from the generator and extend its service life. As for the oil, diesel oils in CD or CE formulations are used for stations of this type.
Nuances of operation in wintertime
Subject to the installation rules and operating recommendations, you can count on the stable performance of the generator function. However, in winter, at negative temperatures, problems of a different kind are not ruled out. The fact is that in frosty conditions, diesel fuel can thicken, which will not allow you to activate the generator. The way out can be the use of fuel heating systems, which are supplied with some generator sets. Diesel can also be heated with a building hair dryer, but only in compliance with safety measures. To minimize the risk of fire, heating should be carried out in a closed container and with the engine turned off. The use of a special brand of fuel will also help to avoid unpleasant situations with difficult starting. Usually they use diesel fuel with additives that prevent liquid crystallization at low temperatures.
Maintenance
Compliance with maintenance measures starts atthe process of operation. This is expressed in the control of operating parameters and the identification of uncharacteristic indicators. The operator must constantly compare engine speed, oil pressure and temperature with the optimum values. After work, it is necessary to check the condition of the filters, the reliability of the connections and the function of the electrical contacts. The frequency of comprehensive maintenance depends on the operating conditions of the equipment. For example, in a dusty environment, maintenance of a diesel generator set should be performed every month, provided that the equipment is used regularly. Timely detection of a malfunction will allow not only to get rid of a local problem, but also increase the service life of the generator's overall motor resource.
Installation repair
Of course, it is better to trust the repair of such units to specialists, but there are a number of common problems that can be eliminated on your own. This applies to the replacement of the mentioned filters, candles and other components available for dismantling. It is very important to listen to the operation of the generator - this will allow you to identify the problem earlier. If there is a strong vibration and noise, then most likely there are problems with the engine. In this case, it is advisable to repair diesel generator sets after a thorough diagnosis. By the way, modern models also provide some kind of self-diagnosis option. Thanks to special indicators with alarms, even an inexperienced user will be able to detect a malfunction and take action in time.appropriate action.
Diesel generator manufacturers
One of the leaders in this segment is the French manufacturer SDMO. This company has decades of experience in the power plant market, which allows it to offer both massive stationary high power units and portable generator models. The middle class is represented by Latvian developers from Resanta. Basically, small units with a capacity of 2 to 4 kW come out under this brand. If you need a diesel generator set for private needs, then it is better to contact Hyundai, Champion and Ranger. The advantages of these stations include high reliability, ergonomics and safety.
Recommendations for selection
The main selection criterion should be the optimal combination of the facility's needs for energy supply and generator power. At the same time, it would be wrong to expect that a high-power unit will satisfy any need and be able to act as a universal station. Of course, such models are suitable for the needs of their level, but consumers with minimal requests in this case will overpay. The operation and maintenance of high power diesel generator sets is not effective if they are used to provide energy to houses and premises with lower demands. You should also calculate the dimensions of the unit. The massive design will provide the necessary headroom, but it is more difficult to install. Conversely, small mobile stations will not cause maintenance problems, but will only be able to cover with energyundemanding users.
Conclusion
The modern market offers many solutions for energy supply problems. Along with fuel stations, battery devices can also be a good option. But before choosing between alternative proposals, it is worth considering the advantages that traditional generator sets have. Diesel, for example, although not the cheapest type of fuel, but in the long run it becomes the most profitable source of power for autonomous stations. In addition, diesel fuel does not imply an intense impact on the working elements, which has a positive effect on the operational life of the generator. As for the disadvantages of this kind of generators, they are not cheap and have quite impressive dimensions.
