Compactor garbage trucks are sanitary vehicles used to collect and transport garbage. Compaction garbage trucks are also known as garbage compression trucks, hydraulic garbage trucks, after-loading garbage trucks, compressor garbage trucks, garbage compressor trucks, after-loading garbage compression trucks, garbage collection trucks, designed for daily garbage in living areas and dense areas transport. So, what is the driving force of the garbage truck when it disposes of garbage?
Here is the content list:
Introduction to the structure and working principle of the garbage truck power system
What is the difference between power steering and power steering of a garbage truck?
Garbage trucks usually use electronic hydraulic power steering systems to complete their operations
Compression garbage trucks are composed of a special vehicle chassis and a top-mounted garbage disposal structure. Many users have been using them, but they don’t know much about the structure and working principle of the compression garbage truck. Today, I will introduce the structure and working principle of the power system. Help users of compressed garbage trucks, and be able to understand some failure principles and solve them in time.
The auxiliary device power of the garbage truck comes from the power take-off. The power take-off is always installed between the transmission and the engine, before the clutch, and uses the engine as the power source. The power take-off separates the power and drives the gear pump to work. The garbage truck gear pump sucks the hydraulic oil in the hydraulic oil tank through the oil suction filter, and the multi-way reversing valve controls the oil supply. When the multi-way reversing valve works, it makes the skateboard cylinder, the scraper cylinder, the lifting cylinder or the push plate cylinder produce actions to realize the operation. When the hydraulic oil cylinder is not working, the hydraulic oil is directly returned to the oil tank through the multi-way reversing valve. In addition, some power take-off windows on the gearbox side take power through the high gear teeth on the gearbox intermediate shaft or the reverse gear teeth on the reverse gear shaft, and are connected with the gearbox through gears.
In the garbage truck power steering system, as the garbage truck engine starts, there is a "sliding vane pump" that produces high-pressure oil, also called "high-pressure oil pump" to output high-pressure oil, and the high-pressure oil enters the "distribution valve" that communicates with the steering shaft. Some people mistake this structure as "booster pump"), high-pressure oil pushes the cylinder piston on the steering rod to reduce manpower.
Hydraulic power steering for garbage trucks is much more complicated than electronic power steering. It requires a set of complex hydraulic pipelines to transfer hydraulic energy, and a set of hydraulic control valves to control these energy, and finally a set of hydraulic cylinders to transfer the energy to the steering wheels. Hydraulic power steering has been developed for almost a century, so the technology is quite mature, with good road information feedback, precise control, so the penetration rate is the highest.
Therefore, in the garbage truck power steering system, there are only the names of "high pressure oil pump", steering oil "distribution valve" and "cylinder piston (also counted as a pump)". The so-called electronic power steering for garbage trucks means that the steering power of the steering system is provided by the electric motor; while hydraulic power means that the steering power of the steering system is provided by the oil pressure generated by the hydraulic pump. Electronic power steering consumes electric energy. This kind of energy conversion efficiency is relatively high, the energy loss is small, and the engine power loss is also small.
Nowadays, some garbage trucks are equipped with electric power steering. In fact, they still need a hydraulic system, but the fuel is supplied by an electric motor. This is the electronic hydraulic power steering system. The electronic hydraulic power steering system overcomes the shortcomings of the traditional hydraulic power steering system.
Therefore, the working state of the garbage truck is the most ideal state calculated by the electronic control unit according to the vehicle's driving speed, steering angle and other signals. Simply put, when turning at low speeds and large steering, the electronic control unit drives the electronic hydraulic pump to run at high speed and output greater power, so that the driver can drive the direction and save effort; on the contrary, the electronic hydraulic pump runs at a lower speed, without affecting the high-speed driving. While turning, some power is saved.
For example, a compacted garbage truck consists of a truck chassis, a sealed garbage bin, a hydraulic system and an operating system. The whole vehicle is fully sealed, self-compressing and self-unloading. During the compression process, the waste is crushed and squeezed and the sewage is collected in the sewage tank, which completely solves the problem of secondary pollution during transportation and avoids the inconvenience caused to people. The operating system can be manual or electrical control.
The key components are imported, with high pressure, good sealing, convenient and safe operation. In addition, according to different requirements, different container capacities can be configured. Compact garbage trucks can be made from 5m3 to 20m3, and from 4 tons to 16 tons. Different brands of chassis can be provided, and other special configurations can also be customized. All in all, compaction garbage trucks are very convenient for garbage collection and have the following characteristics.
1. High compression ratio, large carrying capacity, good airtightness, convenient maintenance, high efficiency, convenient operation and safety.
2. Equipped with a sewage collection box, which can collect the dirt water squeezed out of the trash can. The size can be customized according to actual needs.
3. According to specific conditions, it can be switched to manual or electric control mode.
4. Equipped with a sealing rubber gasket to prevent dirt from splashing out of the cargo during compression.
