The following technical guide allows the reader to know more about the fan blade and its functioning within the cooling system of an internal combustion engine. Besides, you will find the selection criteria to acquire the correct replacement for your fan blade and how we can make your fan blade search easier.
What is a Fan Blade?
A fan blade consists of a device that rotates to take air from the atmosphere and addresses it -at high speed- to a specific point. This part is an essential component of a forklift cooling system; it allows the air passing through the radiator to lower the coolant temperature.
How Does a Fan Blade Work?
Generally, a fan blade of a cooling system is designed to supply the airflow against pressure loss. It could work through two principles: mechanical or electrical.
When the fan blade works with a mechanical system, it starts working when the engine is running. A fan belt connects the crankshaft with other equipment, including the fan. So, the belt transmits the rotational energy from the crankshaft to the pulley, making the fan blade spin. This type of fan uses a clutch which can be thermal or non-thermal.
In the case of a thermal fan, a clutch uses a bi-metal thermal sensor that expands or contracts depending on the system's heat. This sensor permits the clutch to decouple when the engine is cold.
A non-thermal fan clutch is moving continuously at a 30 -60 percent rate compared to the water pump speed.
On the other hand, If the fan works electrically, the system will be composed of a motor, a fan shroud, and the fan blade. The motor and the blade will be mounted on the shroud positioned directly on the radiator. It uses a DC motor that runs or remains turned off depending on the temperature detected by a control unit or a temperature switch.
When Does a Forklift Fan Blade Need to be Replaced?
Although a fan blade is just a piece that rotates, it is fundamental for cooling the coolant, which controls the engine body temperature. If the fan does not work correctly, the air flowing through the radiator will not be enough to lower the temperature of the hot coolant. It causes that the cooling will not be optimal, and it will cause an overheating of your forklift.
Despite a good quality fan blade design being durable, an external agent such as stones, screws, nuts, or other objects might cause physical damage to the blade. If this occurs and the damage is significant, the replacement of the fan blade is required.
How To Choose The Correct Fan Blade for your Forklift?
The design of this device depends on the requirements of the cooling system, but also the manufacturer, as is shown in the following video where a Toyota fan blade is compared with other makers:
While looking for a suitable replacement for a fan blade, the following aspects are taken into consideration:
Dimensions: The new fan blade must match the damaged one in parameters such as large holes, the distance between large holes, and its profile. In this way, we can ensure the new fan can work in the physical space available.
The number of blades: this criterion is essential, given that if the quantity of blades is greater than the blade designed for that system, the motor or pulley will require more power to make the fan rotate, and therefore the airflow rate is less. Commonly the fan blades have 5 or 6 blades.
Construction material: Most forklift fan blades are made of metal std or PVC std. Considering that it will work in a hot environment, the construction materials must be resistant to high temperatures and comply with safety requirements.
Fan blade types: There are two main types: Axial and Centrifugal. The Axial fan is the most common type of fan blade used in a forklift cooling system. Its name comes from its working principle. When this blade type functions, it exerts a suction force that draws the air to be expelled on the other side with a high flow rate. Unlike axial fans, the direction of the air that draws a centrifugal fan is expelled at 90 degrees.
The above considerations are helpful when it comes to finding a suitable replacement fan blade. However, there are two easier ways:
Knowing the Part Number
The part number can usually be found on the old blade or on the manufacturer's website. Once you have the part number, you can use it to search for compatible blades at online retailers or in store. Keep in mind that some manufacturers offer different blades for different models of fans, so be sure to check compatibility before making your purchase. With a little research, you can easily find the right replacement blade for your fan.
Providing Information about Forklift Model and Type
The model number will help ensure that you get the correct size and style of a fan blade, while the type will determine how the blade attaches to the forklift. It is important to be sure about the supplier's knowledge because most of the time, forklift fan blades are very similar and only differ in terms of compatibility.
