If you’re planning to buy an asphalt distributor truck, you’ll need to consider the different features that it has. Some of these features include the number of nozzles that it has, the amount of spray that it can give, and the amount of asphalt that it can produce. There are also some safety features that you need to pay attention to.
Circulate asphalt throughout the tank
A distributor truck is a vehicle used to apply an adhesive coating of asphalt to a surface, such as a road. Asphalt can be applied for various purposes, including improving the strength and durability of a surface. It is typically used for paving roads. However, it can also be used for other purposes.
To be effective, an asphalt distributor must be able to deliver a consistent amount of asphalt during each shot. This is accomplished by providing the proper pressure. Also, the temperature of the asphalt must be maintained.
An asphalt distributor unit consists of a storage tank, a circulation system, and a spraying system. All of these components must be checked before and after work to ensure that they are in good condition.
A distributor’s tank should be clean and sanitary to prevent the mixing of different types of asphalt. The unit should also be level, and it should be visually inspected before and after filling. If the tank is not level, the unit may overflow and damage the surrounding area.
The temperature of the asphalt should be monitored with a thermometer. Some distributors use a dial type thermometer, while others have a thermocouple inside the tank. Infrared thermometers are also available.
Ideally, the temperature should be maintained below 100degF to 400degF. Temperatures above this point can cause the asphalt to harden near the tank skin, which could potentially result in an explosion.
Turn all spray nozzles on and off
The purpose of the asphalt distributor is to spray a uniform coat of asphalt onto a pavement surface. In order to achieve this goal, the nozzles on the spray bar must be adjusted properly. There are three main steps involved in the process: adjusting the nozzles, setting the spray bar height and using a spraying tool.
The first step is to adjust the spray bar height to match the desired width. This should be done according to the manufacturer’s recommendations.
Once the nozzles are adjusted to the right size and height, the next step is to measure the nozzles’ angles. The angle of each nozzle must be a 30 degree angle to the axis of the spray bar.
The proper angle will not only prevent distortion of the spray pattern, it will also ensure a smooth and even application. It is advisable to check the nozzles on the distributor in a controlled environment. Using a measuring stick will help.
If you find that there are any clogs in the spray nozzles, you should clean them out. You can do this with diesel fuel and a torch.
You should also make sure the tank unit is clean. A clogged distributor may cause your tack coat to go off the edge of the pavement.
To get the most out of your asphalt distributor, it is important to use a tool to adjust the nozzles. Also, it is a good idea to have a hand sprayer on board.
Control the amount of asphalt sprayed
If you’re planning to spray asphalt on the road, it’s important to control the amount of asphalt sprayed. A sprayer truck can be a manual or automated unit. The operator controls the pump and the valve to control the flow of the asphalt. This allows for consistent application throughout the shot.
Asphalt distributors are powered by a power-driven pump that squirts asphalt onto the roadway under pressure. Some models feature a thermocouple mounted inside the tank for temperature monitoring. Other models have a dial thermometer mounted outside the tank for easy reading.
To control the amount of asphalt sprayed, it’s important to keep the tank topped off. After you fill the tank, you’ll want to check its level at the beginning and end of the project.
Several different kinds of nozzles are available. These are designed to spray a fan-shaped pattern. They can be adjusted to spray a specific height or width.
Some distributors feature a second spray bar. Sometimes this is referred to as a wheelpath bar. It is also possible to adjust the height of the nozzles for a more even distribution of asphalt.
In addition to the standard pump, some distributors have a heat transfer oil heating system. This system keeps the asphalt in the tank heated. Adding hot asphalt to the tank can cause the water to convert to steam. Never leave the burner on while you are spraying.
Heat the asphalt to prevent an explosion
Typically, distributor trucks heat asphalt or emulsions using burners that burn #2 fuel oil or diesel. This heat, while reducing operating costs, can cause problems with the quality and safety of the material.
Electric heat is quickly becoming an option for many contractors and municipalities. Electric heat uses drywell-style heating elements to dissipate heat in a controlled manner. The use of electric heat can improve productivity, reduce the problems associated with fossil-fuel-fired burners, and enhance safety.
In addition to traditional burners, the truck can be equipped with an electric heater. This can save the crew from waiting on the burners to reach a proper temperature, and it can also eliminate the cost of having a crew member wait on the burners.
A distributor truck is an unglamorous workhorse of paving fleets. It is used for short and medium distance transport of liquid asphalt. They are also commonly used to spray binder for surface treatment.
Asphalt distributors are designed with two control systems. One system is an electrical apparatus control system that opens the spraying valve. The other system is a hydraulic or thermal oil system that maintains the emulsion at the correct temperature.
An automatic asphalt distributor is designed to be simple to operate and economical. It was developed through years of construction experience and equipment design expertise.
An asphalt distributor can be used to spray the upper and lower seal layer, as well as the prime layer. To ensure the right amount of spray, a formula is provided by the distributor.
Fill the distributor tank with distributor spray pump
A Howo asphalt distributor truck is a type of truck that spreads asphalt on a roadway. Asphalt is sprayed under pressure from a power-driven pump. The amount of asphalt sprayed depends on the spray bar height. It is essential that the distributor truck is operated properly.
To begin, the tank unit must be clean. This prevents contamination of the asphalt and prevents the mixing of different types of asphalt. In addition, the distributor truck must have the correct valve positions.
The pump pressure should match the application rate for seal coat work. The temperature of the asphalt should be maintained at a constant level. If the temperature of the asphalt changes, it may cause an explosion. Therefore, the proper heating system is needed to maintain the temperature.
The temperature of the asphalt should be monitored by using a thermometer. Some models have dial-type thermometers mounted outside the tank. Others have thermocouples inside the tank.
An infrared thermometer is also used to measure the temperature of the asphalt. However, the mercury thermometer is not always accurate. Using a dial-type thermometer is more convenient.
A manhole is placed at the top of the tank. The lid has a heavy hinge and permits visual inspection of the tank.
The thermocouples are located inside the tank and are usually connected to a mercury thermometer. These thermometers are attached to a chain that keeps them from being dropped.
Inspect the hoses, joints and pipes
Inspecting your hoses, joints and pipes on a regular basis can extend the useful life of your asphalt distributor. While you are at it, consider asking a few questions about the components you are currently using. Aside from the aforementioned pitfalls, some fittings and hoses are ill-suited for the job. As a result, some accidents could occur.
The most important step is to determine your asphalt distributor’s true working condition. A good visual inspection will reveal a few minor issues, but a thorough cleaning and proper lubrication should take care of most problems. It’s also worth keeping an eye out for signs of damage or leaks, such as soiled hoses and clogged nozzles. If you don’t want to take a chance, a quick sanitization of your unit is the best way to avoid costly repairs.
Identifying the proper operating pressure is essential to getting the most mileage out of your distributor. There are two main systems in use: one that uses a separate engine from the pump, and the other that relies on a pump and engine paired with an auxiliary drive. For most users, the latter is the preferred choice, since a well-tuned drivetrain can yield improved mileage and performance.
While not always possible, the proper application of a fuel additive can keep your asphalt distributor running smoothly and safely for years to come. Also, consider purchasing an auxiliary driveline that can be positioned for optimum driving angle, which can save you the trouble of over-driving the machine.
