As a supplier of Dongfeng Swing Arm Garbage Trucks, I am often asked about the hydraulic system of these remarkable vehicles. The hydraulic system is the heart of the swing - arm garbage truck, enabling it to perform the crucial tasks of lifting, transporting, and dumping garbage efficiently. In this blog, I will delve into the details of the hydraulic system of Dongfeng Swing Arm Garbage Trucks.
Basic Components of the Hydraulic System
The hydraulic system of Dongfeng Swing Arm Garbage Trucks consists of several key components. First and foremost is the hydraulic pump. This pump is typically driven by the truck's engine through a power take - off (PTO). The PTO transfers power from the engine to the hydraulic pump, which then pressurizes the hydraulic fluid. The hydraulic fluid, usually a special type of oil, serves as the medium for power transmission within the system.
Next, we have the hydraulic cylinders. These are the actuators of the system. In a swing - arm garbage truck, there are at least two main hydraulic cylinders: one for controlling the swing arm's movement and another for the lifting and tilting of the garbage container. The hydraulic cylinders convert the hydraulic energy from the pressurized fluid into mechanical force, allowing the swing arm to pick up and release the garbage containers.
Valves also play a vital role in the hydraulic system. Directional control valves are used to control the flow direction of the hydraulic fluid, determining whether the hydraulic cylinders extend or retract. Pressure control valves, on the other hand, regulate the pressure within the system to prevent over - pressurization, which could damage the components.
Working Principle of the Hydraulic System
The working principle of the hydraulic system in Dongfeng Swing Arm Garbage Trucks is based on Pascal's law. When the hydraulic pump pressurizes the hydraulic fluid, the pressure is transmitted equally throughout the fluid. When the operator activates the control levers in the cab, the directional control valves direct the pressurized fluid to the appropriate hydraulic cylinders.
For example, when the operator wants to pick up a garbage container, the directional control valve directs the hydraulic fluid to the cylinder that controls the swing arm. The fluid enters one side of the cylinder, causing the piston to move and extend the swing arm. As the swing arm reaches the garbage container, the operator can then use another set of controls to lock the container onto the swing arm.
When it comes to dumping the garbage, the hydraulic system works in a similar way. The operator activates the control to direct the fluid to the cylinder responsible for tilting the container. The pressurized fluid enters the cylinder, causing it to extend and tilt the container, allowing the garbage to be emptied into the designated disposal site.
Advantages of the Hydraulic System in Dongfeng Swing Arm Garbage Trucks
One of the significant advantages of the hydraulic system in Dongfeng Swing Arm Garbage Trucks is its high power - to - weight ratio. Hydraulic systems can generate a large amount of force with relatively small and lightweight components. This means that the trucks can handle heavy - duty tasks without being overly bulky.
Another advantage is the smooth and precise control. The hydraulic cylinders can be extended and retracted in a very controlled manner, allowing the swing arm to pick up and release garbage containers with great accuracy. This is especially important when working in tight spaces or when dealing with different sizes of garbage containers.
The hydraulic system also offers high reliability. Dongfeng uses high - quality hydraulic components that are designed to withstand the harsh operating conditions of garbage collection. The hydraulic fluid is also carefully selected to have good lubrication and anti - corrosion properties, ensuring a long service life for the system.
Different Models and Their Hydraulic System Features
We offer a variety of Dongfeng Swing Arm Garbage Trucks, each with its own unique hydraulic system features. For example, the Dongfeng 8CBM 4X2 Swing Arm Garbage Truck Waste Rubbish Container Truck is designed for medium - scale garbage collection. Its hydraulic system is optimized to handle the 8 - cubic - meter capacity container efficiently. The hydraulic cylinders are sized appropriately to provide the right amount of force for lifting and tilting the container.
The Dongfeng Swing Arm Rear Loader Garbage Truck Light - duty Truck is a more lightweight option, suitable for urban areas with narrow streets. Its hydraulic system is designed to be more compact and energy - efficient, while still providing sufficient power for the rear - loading operation.
The Dongfeng 15m³ Hot Swing Arm Garbage Truck is a heavy - duty model. Its hydraulic system is built to handle the large 15 - cubic - meter container. The hydraulic pump has a higher flow rate and the cylinders are larger in diameter to generate the necessary force for lifting and dumping the heavy load.
Maintenance of the Hydraulic System
Proper maintenance of the hydraulic system is crucial to ensure the long - term performance of Dongfeng Swing Arm Garbage Trucks. Regularly checking the hydraulic fluid level is essential. Low fluid levels can lead to cavitation, which can damage the hydraulic pump and other components. The fluid should also be changed at the recommended intervals to maintain its properties.
Inspecting the hydraulic hoses and connections for leaks is another important maintenance task. Leaking hydraulic fluid not only reduces the system's efficiency but can also pose a safety hazard. Any damaged hoses or connections should be replaced immediately.
The hydraulic filters also need to be replaced regularly. These filters remove contaminants from the hydraulic fluid, preventing them from entering the system and causing damage to the components.
Conclusion
The hydraulic system of Dongfeng Swing Arm Garbage Trucks is a well - engineered and reliable system that enables efficient garbage collection. Its advanced design, high - quality components, and precise control make it a key feature of these trucks.
