Loader is one of the common construction machinery. Many people will consider the model and equipment of the loader when purchasing it. They often associate models and equipment directly with prices. However, they did not know that the later maintenance and repair of the machine is also very important, especially the application damage and effective production service life of the parts used in various parts of the machine, especially the key components, are one of the important factors affecting the entire machine experience.
Some work continuously and some work intermittently. First of all, there should be different differences and identifications in these major situations, and basic maintenance should be done well. Whether it is daily use or long-term interval, the maintenance schemes are different. After 3000 hours of work by professional machine manufacturers, most of the second-hand agricultural loaders will shake the instrument panel and the cab. Some cutting instrument panels and the cab shake more and more seriously, Jitter causes that many data cannot be measured and displayed accurately and cannot be used normally. What are the following reasons and solutions for jitter analyzed by Laizhou Kaixing installation and cutting technicians?
Cause and Solution of Abnormal Jitter of Instrument Panel of Second hand Loader
The hydraulic system of the cutter adopts the way of steering priority. The pressure oil output from the steering pump and the pressure oil output from the working pump combine to supply oil to the working equipment. The working pump only bears the load of the working equipment, while the steering pump not only bears the load of the working equipment, but also bears the load of the steering. Therefore, the steering pump works for a long time and is severely damaged. This is one of the important factors that cause the loader dashboard and even the cab to shake.
Under the joint action of priority valve body, valve core, pressure regulating spring and pressure oil, the EF port switch of wheel loader will convert to each other at a certain frequency, which will produce vibration at a certain frequency. As the vibration is close to the instrument panel, the natural vibration frequency of the cab is close to the instrument panel, causing resonance between the instrument panel and the cab. This is also a common cause of jitter. Therefore, in order to solve the problem of abnormal shaking of the loader, we should not only remove the causes and elements of irreversible damage to the parts, but also regularly maintain the key components of the installation and cutting machine.
