Turbochargers in agricultural tractors
At first, turbochargers were used only in tractors with high power., but today they are installed even in small mini-tractors and walk-behind tractors.
Why are turbines installed on tractors??
The use of a turbocharger has many advantages. This allows you to get more power for the same force., while reducing fuel consumption. Turbine pumps more air, i.e. oxygen, into the combustion chamber, accordingly, more fuel can be burned at the same time, which results in higher engine power.
Turbocharging has a greater influence on the formation of the combustion process, eg, for the combustion of lean mixtures and reduces emissions of harmful substances.
In practice, we get a higher torque, as well as more favorable work – high value is reached at lower rpm. In this way, turbocharged engines:
- more economical,
- more powerful,
- greener,
- more efficient.
You can be sure, that turbochargers will not disappear from agricultural machines for a long time, who need such parameters.
Where to buy turbochargers for tractors
Turbines of tractors and other agricultural machines do not last forever, and the risk of damage is greatly increased., if the user forgets a few basic rules, associated with a turbocharged engine. Depending on usage, the service life of a turbocharger ranges from several hundred, up to several thousand hours.
At present, there are various brands of agricultural tractors. The farm uses different tractors depending on the type of work and the required tractive effort.:
- for heavy or light work;
- nursery or vegetable garden;
- general use;
- work in mountainous areas…
These tasks can be completed with a variety of tractors, such as MTZ, ЮМЗ, John Deere, Kubota, Perkins… Modern tractors are designed like this, that the engine is by default combined with a turbocharger. But, Unfortunately, over time, the turbocharger may start to work erratically or fail. In this case it will be necessary to replace it..
looking for, where to buy an MTZ turbocharger in Ukraine, ЮМЗ, John Deere or other brand, you may encounter inaccurate information, wrong tractor names, lack of turbochargers on websites. In the online store d-zapchast.com.ua you will not encounter this problem, because they took care of that, so that you can find the right turbocharger for your machine in the best possible way.
Even in that case, if you do not know exactly how to choose the right turbocharger, help you. Just contact a company representative at: +38097-08-345-08 and he will select the best option for you.
Turbochargers in tractors and agricultural machines – User's manual
To minimize the cost of frequent replacement or regeneration of the turbocharger, nothing else remains, other than to make sure it works properly. To understand, why should one act differently when starting and stopping a supercharged engine, I will explain how it works.
Fixed power turbocharger (popular on older tractors and farm equipment) basically a very simple device. Its main component – it is a rotor with a turbine at one end and a vane compressor at the other. The turbine is driven by the pressure of the exhaust gases, and the compressor on the other hand pumps air into the cylinders.
In turbochargers with variable geometry, the design becomes more complicated. Moreover, it has a steering wheel element with a control system, which directs the flow of exhaust gases, by increasing the rotor speed, which increases the pressure at low speeds. This solution increases the risk of failure due to more moving parts.
In a turbocharger without geometry, only the rotor and its bearing or compressor blades can be damaged.. When changing geometry, steering wheel elements are usually damaged..
Theoretically, the durability of turbochargers is very high., but they work in very adverse conditions: high temperature of the exhaust gases causes a strong heating of the mechanism, ensure adequate lubrication of the rotor, which rotates at speeds up to 200000. about / i. Such high speeds are possible thanks to a special lubricant., so-called oil film, formed by oil, under high enough pressure. Lack of oil or level drop (even temporary), most often results in immediate damage to the rotor surface and (or) plain bearing.
Therefore, the key to the longevity of a turbocharger is starting and stopping the engine.. When the engine is stopped, most oil channels are empty, oil flows into the sump, so the engine starts cold, may take some time, to allow the oil to reach the turbine wheel and provide adequate lubrication. Why, to avoid faster wear of the turbocharger in our tractors, you should always wait a few tens of seconds, before revving the engine.
An equally important point – engine stop. The turbine rotates at high speed, stops later, than the engine, keeps spinning, the oil pump is no longer working.. It also contributes to rotor wear.. Before, how to turn off the engine, need to let it idle for a bit, so that the turbocharger cools down and the rotor loses speed.
Another common cause of turbine failure is the wear of the air intake blades due to the ingress of foreign bodies into the system.. It could be a "random" nut or an air filter, which passes dust and wears out over time. Be careful and change consumables in time!
