System effectively shortens the operation cycle, achieving a notable 15% reduction in fuel consumption rates. This system not only enhances overall operation efficiency and economy but also minimizes the shift impact resulting from changes in driving direction or rapid engine shifts. Consequently, it contributes significantly to diminishing driver fatigue during operation.
The loader's Load Sensing System is remarkably effective in reducing the power demand of the loader. The Electronic Servo Control and Information System on the loader consists of an LCD screen and a keyboard which is capable of displaying and recording a comprehensive range of information. The automatic diagnosis function of the loader records machine failures and stores relevant information systematically, allowing for coding. The incorporation of anti-theft computer management and monitoring emerged as a crucial indicator of loader development internationally during the 1990s. The computer management and monitoring system exhibit the capability to consistently oversee numerous parameters of loaders. It encompasses functions such as fault diagnosis and alarms, enabling the recording and processing of various operational information related to the loader. Additionally, it can display the working status of components with liquid crystal display.
The connecting rod mechanism is engineered to withstand immense torque loads, showcasing outstanding reliability and durability. Its operational performance is comparable to that of a parallel lifting mechanism. The working device is designed to horizontally lift or lower materials on the bracket. It can be equipped with various operating devices to minimize the driver's inclination angle from the ground to the maximum height of the bucket. After 3000 hours of operation, there is an observable phenomenon of instrumentation and cab jitter. Over time, this jitter issue tends to intensify, reaching a point where not only the cab experiences vibrations, but the entire machine is affected by this increasingly severe jitter. The shaking phenomenon has led to inaccurate material weighing, rendering normal usage impractical. Shandong loader technicians will now .
provide an analysis of the causes behind this jitter.
1.The hydraulic system of loader adopts steering priority mode. This entails the combination of pressure oil from the steering pump and pressure oil from the working pump to supply oil to the working device. Notably, the working pump is tasked with bearing the load exclusively during the movement of the working device. In contrast, the steering pump not only bears the load during the movement of the working device but also during steering. Consequently, the steering pump undergoes prolonged usage, resulting in comparatively greater wear over time.
2. The EF port undergoes a periodic opening and closing, influenced by the combined action of the preferred valve body, valve core, pressure regulating spring, and pressure oil. This results in vibrations occurring at a specific frequency. The critical factor is that this vibration frequency closely aligns with the natural vibration frequency of both the instrument and the cab. Therefore, resonance takes place within the instrument and cab, exacerbating the vibration phenomenon.
