truck air brake tanks

Types of Truck Air Brake Tanks

Heavy-duty trucks use air-brake systems for stopping safely. These trucks have big air compressor tanks (also known as reservoirs) that store air. The stored air forces brake pads to contact with brake discs when truck drivers press brake pedals. This contact slows down or stops the wheels from spinning. The tanks need regular maintenance. They must be cleaned of moisture and debris to ensure effective braking. Truck air brake tanks come in different sizes and types. They include:

• Steel tanks: Many trucks have steel tanks. The steel material is robust and ideal for high-pressure applications. The tanks have a high-pressure rating. This means they can hold a lot of compressed air. They also have a thick wall to withstand extreme conditions. For instance, rough vibrations or physical impacts. Unfortunately, steel tanks are susceptible to rusting. Especially when water condenses inside the tank. The rust can break down the structural integrity of the tank. To prevent this problem, truck owners must regularly drain the tank. They must remove the accumulated water. Steel tanks also come in different shapes and sizes. The choice depends on available space and specific application requirements.
• Aluminum tanks: Aluminium tanks are lightweight. They are ideal for weight-sensitive applications. For instance, in long-haul trucking. The tanks also have good corrosion resistance. This makes them suitable for environments with corrosive elements. The aluminium tanks are also robust and have a high-pressure rating. Like the steel tanks, they can hold a lot of compressed air.
• Composite tanks: Composite tanks are less common. They are ideal for modern trucks that prioritize weight reduction. The composite tanks are lightweight and have good corrosion resistance. They also have a multi-layer construction. Each layer has a different role. For instance, one layer can reinforce structural strength while another layer can provide barrier properties.
• Fiberglass tanks: Fiberglass is a plastic material that is reinforced with glass fibers. The tanks are robust and corrosion resistant. This makes them suitable for harsh environments. For instance, areas with chemical exposure or extreme weather conditions. The fiberglass tanks also have impact resistance. This protects them from physical damage due to accidental drops or impacts.
• Carbon fiber tanks: Carbon fiber is another composite material. It is very lightweight and has a high tensile strength. Carbon fiber tanks are suitable for applications that require quick braking response. For instance, in racing trucks that need high-speed performance. The tanks also have excellent fatigue resistance. This reduces the risk of failure due to repeated stress from braking operations.

Specification and maintenance of truck air brake tanks

Brake tanks for heavy trucks, also known as air tanks, reservoir tanks, or storage tanks, have the following specifications:

• Purpose

  These tanks store compressed air used for the truck's braking system.

• Material

  Air brake tanks are usually made of steel or aluminum. They are strong and resistant to rust.

• Capacity

  The capacity of a semi-truck air tank is different, and it is measured in gallons or liters. The size is determined by the truck size and the braking system's requirements. The capacity of the tank ranges from 2-4 gallons (7.5-15 liters) or more.

• Operating Pressure

  The tanks are designed to handle high pressure from the compressed air, usually 90-120 psi (620-830 kPa) or more. This pressure is used to power the brakes effectively.

• Connection Ports

  There are several ports in the semi-truck air tank that are used to connect to different components of the air system for intake, exhaust, and pressure gauge connections. The ports are usually threaded and have different sizes to fit the system's requirements.

• Drainage

  Most tanks come with a drainage valve at the bottom. This allows the water and contaminants trapped inside the tank to be drained regularly.

• Mounting

  The tanks are usually mounted on the chassis or under the truck bed using brackets and rubber dampers. This minimizes vibrations and protects the tank from damage.

• Coatings and Corrosion Protection

  Some heavy-duty trucks' air tanks have coatings or linings to prevent rust and damage from chemicals or road debris.

Air brake tanks are an important part of the truck's braking system. If the tank has a problem, it can affect the tank's performance. Here are some maintenance tips to ensure the tanks work well:

• Inspect the tank regularly for signs of corrosion, leaks, or damage and repair them immediately.
• Drain the air brake tank daily to remove moisture and contaminants that can build up inside the tank.
• Check all the connections, ports, and fittings for leaks or damage and replace them as soon as possible.
• Test the tank pressure gauge regularly to ensure it is functioning properly. Replace it if it is damaged or inaccurate.
• Clean the air brake tank and the surrounding area regularly to prevent dirt and debris from entering the tank.
• Once a year, conduct professional maintenance on the air brake tank to ensure it is in good condition and functions effectively.

How to Choose a Truck Air Brake Tank

Choosing the right air brake tank requires careful consideration of several factors:

• Capacity:

  The capacity of a truck air brake tank is vital as it influences the compressed air quantity available for brake system usage. A larger tank will provide more air and require longer periods to fill, while a smaller tank will fill quickly but provide less air supply. Therefore, buyers must evaluate their needs and the truck's size and driving conditions before selecting a suitable capacity. Typically, tanks with a capacity of 5 to 10 gallons are common.

• Material:

  The material of the air brake tank determines its durability and weight. For instance, steel tanks are robust and resistant to damage but may corrode over time. On the other hand, aluminum tanks are lightweight and do not corrode easily but may be prone to dents. Thus, buyers should choose a material that will suit the tank's intended use and the environmental conditions.

• Mounting Options:

  The mounting options are equally important since they determine how and where the air brake tank will be mounted on the truck. Common mounting options include side mounting and bottom mounting. Buyers should select a mounting option that will ensure a secure and stable tank fit.

• Drainage:

  Drainage is a critical feature in an air brake tank. During the compression process, moisture is created, which may accumulate in the tank and affect the braking system's efficiency. Thus, buyers must choose tanks designed with drainage mechanisms to ensure the collected moisture is removed.

• Pressure Rating:

  The pressure rating is also an important consideration when choosing an air brake tank. The tank's pressure rating must be compatible with the requirements of the truck's air brake system. Therefore, buyers must ensure that the tank's pressure rating is equal to or exceeds the specifications of the air brake system.

• Size and Weight:

  The size and weight of the air brake tank are crucial as they influence the tank's fit on the truck and the ease of its installation. Large and heavy tanks may pose mounting challenges on the truck, while small and lightweight tanks may be easily mounted. Therefore, buyers must select a suitable size and weight that will ensure the tank's simple and secure installation.
