Operation of power plants. How to start a diesel generator for home from an external source? Storage and handling of lubricants

Modern gasoline, diesel and gas generators are reliable devices that are equipped with several levels of protection.

The presence of special elements allows you to protect equipment and prevent its failure. However, even the most advanced and secure system is not able to work stably if it is not launched correctly. Only by understanding how to start a generator can you ensure efficient operation of the equipment in any conditions.
Correct startup and use of the device reduces to zero the possibility of breakdowns due to human factor and guarantee the longevity of the generator.

Preparatory work

After unpacking the power plant, it must be carefully examined to ensure that there are no breakages or defects that could have occurred during transportation. Before starting the generator, you need to make sure that all components are connected to each other.

When purchasing a new generator, it comes with instructions from the manufacturer, which you need to read. Even if you are an experienced specialist who has already dealt with energy-generating devices, it is possible that this model is distinguished by its special properties. The generator is a high-tech device, and almost every model on the market has its own nuances that you need to pay attention to during use.

Before starting the generator, it will be necessary to fill the device with suitable and high-quality oil. Considering the fact that the generator consumes a minimal amount of oil, it is best not to save money and buy proven brands, since it is the quality of the oil that plays the main role in ensuring the longevity of the equipment. When choosing oil, it is necessary to take into account the temperature conditions of the area where the generator will be used.

Starting different types of generator

Starting a gasoline, diesel, or gas generator must be carried out taking into account the characteristics of each individual type. Only strict adherence to the rules will allow for a correct launch and not damage the equipment.

Launch types

To turn on any unit, you need to take into account the features of the starting system. Generators on the market today are distinguished by the following engine starting systems:

A mechanical system that can very often be seen in gasoline and diesel power plants. In order to start such a generator, you need to pull the cord handle towards you until you feel resistance. There are times when the power unit refuses to start the first time. You just need to repeat the procedure until the generator starts working. If an inverter generator is installed, then you will need to carry out slightly different manipulations. Before starting the generator, you should connect the power and only then pull the handle and open the air damper;

Starting using an electric starter. Before you start a generator of this type, you must make sure that the terminal is securely fastened. You should also make sure that the battery is installed and ready to use. The fact is that not all manufacturers equip their units with built-in batteries, as a result of which they have to be purchased separately;

Automatic start. Distinctive feature units with a self-start function is that they turn on immediately after a power outage. Before switching the load, you need to let the unit idle so that in the future it can provide stable power generation.

Using a diesel generator in cold weather

Starting a diesel generator in the cold in winter is a complex process that requires strict adherence to the rules. Otherwise, the unit may be damaged. When trying to start a generator at low temperatures, a number of problems may arise that can only be solved in a comprehensive manner.

The first way to solve this problem is to install a pre-heater on the cooling circuit of the power plant. This device is used to heat the fluid in the cooling system, which may freeze due to low temperatures.

The second option is more practical: it involves placing the diesel generator in a special container that protects the unit from excessive cold. If the device is in such a container, then starting it will not be difficult even in the most severe frosts. The distinctive advantage of such containers is that they not only protect from the cold, but also significantly reduce the level of noise produced. That is why starting a diesel generator in cold winter conditions is considered the best option.

Features of starting a gas generator

Before starting a gas-type generator, it is extremely important to ensure that there is enough oil and also disconnect the load.

After all the necessary manipulations have been completed, you should:

Turn on the tap that is responsible for the gas supply;

Turn on the power plant;

Close the air damper.

All other manipulations fully coincide with those that need to be done when working with other types of devices.

Features of engine running-in

If the power unit is being launched for the first time, it is necessary to run it in, which will have a positive effect on the durability of the device. The essence of the run-in is to turn on the equipment at 50% power and let it work for two hours. In this case, you should constantly monitor the oil level, thanks to which you will also be able to find out how much oil the generator actually consumes during its operation. Such equipment cannot stand idle long time, as this negatively affects the time of its uninterrupted operation.

A diesel generator is a rather complex mechanism. Let's say you purchased a diesel generator set, then a lot of questions arise: how to start the unit for the first time, how to work when connecting the load, what to do in case of equipment breakdown, where to carry out maintenance. Our service center “Rem Tech Service” can help you with all these questions.

Our experienced specialists know almost everything about diesel generators. We will be happy to help you with all of the above issues. We do everything professionally, quickly, and most importantly inexpensively. Call by phone:063 202-90-70 097 023-42-42.

Today, we will look at the example of the SKAT installation, how to step by step how to correctly start the diesel generator for the first time, connect the load to it, and accordingly stop the unit. So, let's begin.

  • We unpack the generator and carefully inspect it for external damage.
  • We check the equipment specified in the manual, be sure to make sure that there is nothing inside the unit.
  • It is advisable to install the chassis first; in the future this will be a huge plus, as it will make it easier to move the unit.
  • Let's take a close look at the instrument panel; in the upper part there are monitoring and control devices, in particular: the ignition switch, an indicator for an emergency drop in oil pressure and overload of the unit. What is the top indicator? Upper indicator- this is an oil drop indicator, it tells us about the presence of oil pressure in the internal combustion engine system.
On a note! As long as there is no pressure in the oil system, you will not be able to start the unit. Before pumping the fuel system of the unit, you need to make sure that the oil pressure indicator does not light up.

Overload indicator, lights up when consumers are connected that exceed the power of the diesel generator. Also, on this panel you can see a voltmeter and an hour meter. The latter is very important, as it is able to promptly indicate when maintenance is necessary.

  • In this version, which we are considering, batteries are supplied ready for use. We join power wires to the battery terminals, while observing an important condition - taking into account the polarity.
  • The next stage is filling the crankcase (the capacity of which can be seen in technical specifications). We unscrew the oil filler button-dipstick, measure out the amount of oil we need and fill the crankcase (it is advisable to do this through the oil filler neck). Next, install the button-probe in place and tighten it well.
Advice! Whether the oil level is sufficient can be determined using the marks on the dipstick. The manipulation of checking the oil level should be carried out before each start of the engine.
  • A diesel engine is lubricated under pressure, so you need to distribute the oil throughout the oil system before starting the engine. To do this, squeeze out the compressor, and then turn the engine crankshaft with an electric starter. This must be done until the emergency oil pressure lamp goes out.
  • It is absolutely not worth using a decompressor to stop the engine. This can lead to destruction of parts of the gas distribution mechanism.
  • Then, we fill the fuel tank and prepare the fuel system for operation. To avoid premature repair of the unit, purchase only high-quality diesel fuel. To fill the tank, it is better to use a funnel, which helps avoid spilling diesel fuel past the filler neck. After filling the tank with fuel, open the filler valve. To fill the fuel system and filters, you need to wait a while (2-3 minutes).
  • The next step is removing air from the fuel system. First, loosen the fuel wire nut a couple of turns. high pressure on the fuel pump. While holding the decompressor, turn the engine crankshaft. This should be done evenly until fuel flows out from under the nut (and it is important to ensure that there are no air bubbles).
  • We do the same manipulation with the nut on the fuel injector. Tighten both nuts.
  • After the above operations have been completed, your diesel generator set is ready for operation.
  • SKAT generators are equipped with both a manual and an electric starter. Manual starting is used when the electric engine starting system is faulty.
  • So, start with an electric starter. To begin with, we make sure that the fuel tap is open, set the ignition switch to the “on” mode, hold the compressor pressed, and crank the engine crankshaft with an electric starter until it picks up maximum speed, release the decompressor, while not forgetting to rotate the crankshaft. It is practically impossible to completely remove air from the fuel line, so the generator engine may operate unstably for some time.
  • Let's look at how to start the unit using recoil starter. We make sure that the fuel valve is open, then turn on the ignition, pull the starter handle until resistance appears, this corresponds to the dead center of the engine, return the starter handle to its place. Then, squeeze out the decompressor and pull the starter handle.

And generators are high-tech, reliable and durable devices. All modern generators are equipped with several stages of protection. Design elements prevent device breakdowns. Under the influence of aggressive environments, and especially humans, it is necessary to start correctly.

Correct startup of the device and correct use reduce the likelihood of breakdowns and prevent its failure.

After unpacking the power station, perform a complete visual inspection. Make sure there is no damage during transportation. Check that all components are present. All hoses and tubes must be securely connected.

The generator comes with instructions; be sure to read them carefully.

Initially, before using the power plant, you should fill the installation with the required volume motor oil. It is recommended not to skimp on high-quality motor oil; the longevity of the device depends on its good quality.

Next comes the fuel selection process. You can fill the tank of an electric generator not only at a gas station, but also using an intermediate container. Fuel containers must be kept clean. The presence of dirt, water and other foreign objects in them is not allowed.

Before starting the device, make sure that the surface on which the electric generator is installed is smooth. Running the unit with an exhaust system is prohibited indoors. Care must be taken to ground the device for safe use.

Starting the diesel generator

The device starts when there is no load. There are autostart modes and an electric starter system and mechanical start (manual).

To start working with a diesel power plant with mechanical start, you need. Pull the starter cord handle until there is resistance. After this, pull the handle with a sharp movement. It is not recommended to immediately release the handle as the cord should return to its original position. If unsuccessful, repeat the procedure.

After warming up the internal combustion engine, it is allowed to open the air damper.

To start working with a diesel generator with an electric starter, you need to make sure that the battery terminals are securely fastened with correct polarity. Starting is done by pressing a special button or using a key, like on a car.

You can buy various models of generators with manual start or auto start on our website.

It may seem that there should be no difficulties with launching. You just need to pull the cord and everything will start working. However, there are certain nuances that must be taken into account in order to know how to launch.

Launch step by step

By following certain recommendations, you can start the generator without any problems.

You need to do the following:

  1. The unit must be unpacked and carefully inspected. There should be no external damage, and there should be no foreign parts inside;
  2. There is an indicator on the dashboard showing oil pressure. While there is no pressure, the installation will not be able to start. Bleeding the fuel system should only begin after checking that the indicator is not lit;
  3. Be sure to ground the generator. This will help avoid electric shock during operation;
  4. The device must include rechargeable batteries. Power wiring must be connected to the battery terminals. When doing this, remember to maintain polarity;
  5. Fill in the required amount of oil. First, read the instructions, it indicates the brand suitable for a particular generator. Then the oil filler plug is unscrewed and measured required quantity and the crankcase is filled through the neck. It is important each time before using the generator to use a special dipstick and check what level the oil is at;
  6. Lubricant is distributed to the system before you start. First, the decompressor is squeezed out. At the same time, you need to start cranking the crankshaft until the lamp responsible for the emergency pressure level goes out completely. Do these actions for no longer than 5 seconds;
  7. Proceed to filling the fuel tank. It is recommended to use only fuel from high-quality manufacturers. Seasonal fuel changes are also required;
  8. The fuel valve should be opened;
  9. The final stage requires removing all air from the fuel system. First, the tank is completely filled, then the tap is opened. Find the pump nut that needs to be turned 1 turn. Place the decompressor so that it is in the open position. Don't let go, hold it. Using the starter, crank the crankshaft until fuel begins to flow. This should appear under the nut. There should be no air bubbles;
  10. Next, the pump nut should be tightened tightly. Locate the injector nut. It needs to be unscrewed 1 turn. Rotate the crankshaft again. Finally, shade the nut tightly.
This way you can get rid of air in the fuel system. To start, you need to start pulling the starter handle until there is noticeable resistance. Then return it to its original position. Then you need to press the decompressor and release. Using strong, long strokes, begin to pull out the starter handle. Do not make sudden movements, but strong ones. Do not pull the brush into your armpit area. This will cause the flywheel to spin in the opposite direction. The hand will be severely torn.

The steps listed above help you understand how to start a diesel generator. Sometimes all the air does not leave the system. Therefore, the device may experience instability in the first couple of minutes.
