Farm Tractor 70hp Air Conditionor Cabin

1) As the main power source for the tractor's electrical system, the generator's output power, voltage, and current should meet the power requirements of all electrical equipment on the tractor.

2) Electric-start tractors generally use batteries. When the tractor is operating normally, the generator should not only supply power to the electrical equipment but also charge the battery with excess energy. This type of electrical system requires direct current (DC). If an AC generator is used, the AC power should be converted to DC; therefore, a rectifier should be provided.

3) In electrical systems using batteries and DC generators, there should be a device to prevent battery current from flowing back into the generator. There should also be an overload protection device for the generator, and a voltage regulator to maintain stable output voltage when the generator's speed changes, ensuring normal operation.

4) Tractors not using electric starting do not require batteries. When using an AC generator in the electrical system, a rectifier is not necessary.

5) The generator should have a simple structure, small size, be easy to install and remove from the tractor, operate reliably, and be easy to maintain.

The working principle of a flame preheater is to ignite the fuel flowing into the preheater with a hot resistance wire to form a flame, which preheats the intake air at the intake manifold.
