The load-sensing speed control system of small loaders can shorten the operating cycle, reduce fuel consumption by 15%, improve operating efficiency and economy, reduce the shift impact caused by changes in operating direction or engine high-speed shifting, and reduce the driver's stress. Work fatigue.
? Loader load sensing systems can reduce the loader's power requirements to astonishing levels. The loader is equipped with an electronic servo control and information system consisting of an LCD display and a keyboard for displaying and recording various information. Its automatic diagnostic function records machine faults and stores all relevant information. Through coding, anti-theft computer management and monitoring can be achieved, which is an important symbol of the development of foreign loaders in the 1990s. The computer management and monitoring system can continuously manage/monitor dozens of parameters of the loader, has fault diagnosis and alarm functions, can record and process various information on the loader operation, and uses an LCD to display the work of parts.
Why is the small loader shaking abnormally?
The link mechanism can withstand large torque loads, and its reliability and durability are similar to those of the parallel lifting mechanism. The working device can lift or lower materials placed on the pallet in a horizontal position, and can be equipped with various working devices to minimize the driver's adjustment of the bucket inclination angle from the ground to large heights.
After the loader has been working for 3,000 hours, the instrument panel and cab will shake. The shaking will become more and more serious, and even the cab and the entire machine will shake. Vibration causes the machine to weigh materials inaccurately and cannot be used normally. Below, Shandong loader technicians will analyze the causes of jitter.
1. The loader hydraulic system adopts the steering priority method. The pressure oil output by the steering pump merges with the pressure oil output by the working pump, and then supplies oil to the working device. The working pump only bears the load when the working device is running, while the steering pump not only bears the load when the working device is running, but also bears the load when turning. Therefore, the steering pump works for a relatively long time and suffers large wear.
2. Under the joint action of the priority valve body, valve core, pressure adjustment spring and pressure oil, the opening and closing of EF change each other at a certain frequency, resulting in vibration at a certain frequency. Since the vibration is close to the natural vibration frequency of the instrument panel and the cab, the instrument panel and the cab resonate.
