What is the pulley of the fans?

Pulley fan is, as its name suggests, the pulley that is connected to the fan. The pulley is a metal or hard plastic wheel with a grooved outer edge. The track is usually in the shape of V and is designed to match the belt that fits into it. When the belt moves, the pulley is spinning that turns the charge and the connected fan blade turns.

The task of the fan is to move through the air. It has two or more long flat blades connected at one end to the central charge. When the charge rotates, the blades also rotate, and because the blades are slightly tilted, they catch the air and push it behind them. Fans can be mounted directly on the engine shaft, but it is not always comfortable. The hammer is used when the engine is at a certain distance from the fan and power from the engine should be converted to a fan to spin.

fans and fans are an important part of many car engines that produce excess heat. This heat must be removed toprevented overheating and burning motor oil. The water spreads through the engine and pumps into a cooler that absorbs heat from the water. A fan is mounted near the radiator, often powered by a fan pulley. The fan attracts the air through the cooler so that the air can absorb the heat, which it then takes away.

In the high -speed pulleys of fans, for example in cars, it is important that it is good to adapt between the drive belt and the fan. On the belt there is a wheel to maintain the correct voltage between the belt and the pulley to prevent the belt from slipping. When the worn sides of the groove in the fan belt

Fans and pulleys of pulleys precede industrial age. In the hot climate, fans were used to cooling people - and people were engines used to turn them. In some cases slave the maid caught the lever of the arm or a tendon on the feet and the fans were namingNi overhead, where many flaps transmitted strength through the rope.
