Powder metallurgy parts of different types are used in the automotive industry. The PM process involves mixing alloy powder and then compacting the mixture in a die before it is sintered to achieve the desired shape and size. A highly advanced method of developing ferrous and non-ferrous metals, it is a cost-effective solution when the parts are manufactured in large numbers.
Sintered water pump pulley
One of the major parts of a vehicle, the water pump pulley, works by absorbing heat and pushing the coolant inside. As part of a vehicle’s cooling system, this part transfers the movement of the drive belt to the bearing spindle. This, in turn, helps to power the water pump, which prevents the engine from getting overheated. When this pulley is damaged, it can make the water pump inoperative and can damage the engine.
This pulley is used in the vehicle because it provides a wear-resistant and durable surface, which helps to transfer the power from the belt to the water pump. This, in turn, ensures a seamless operation and prevents premature failures, which can happen due to regular wear and tear, especially when exposed to high temperatures and poor driving conditions. The term “sintered” in sintered water pump pulley refers to the process that compact material which is strong with good friction properties.
What are the key features of sintered water pump pulleys?
There are several features of this pump pulley. We have discussed some of the crucial ones below:
- Material properties: Made out of metal powders, these parts are compressed and heated to create a porous structure that is strong and durable. As such, this pulley can easily withstand high loads and regular wear and tear.
- Power transmission: The pulley’s design transmits the required torque to rotate the water pump and circulate the coolant throughout the engine.
- Heat resistance: Sintered metal components are capable of handling high temperatures of the engine quite well without causing any degradation. This is essential for the proper functioning of the water pump pulley.
- Noise reduction: The pulley’s smooth surface helps to reduce the noise generated by the vibrations produced during belt rotation.
What are the major advantages of this pulley?
Also known as the hub flange, this pump pulley has several advantages.
- The pulley helps to transfer the movement caused by the drive belt to the bearing spindle. As a result, the engine does not get overheated.
- By reducing the rotation amount, the pulley helps to reduce the wear and tear of the belt.
- It reduces the wear and tear of other components of the vehicle, such as the bushings, shafts, sealed bearings, power steering pump, alternator, and clutch.
- The pulley helps to increase the acceleration, thereby enhancing the performance of the vehicle.
If you wish to keep your vehicle in good condition and ensure that the engine remains functional, you should ensure to replace the water pump pulley at frequent intervals. When you opt for vehicle maintenance, ask the mechanic to carry out a detailed inspection.
