Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil filter brackets, in particular to an oil filter bracket with an automatic leveling function. Background Technique
[0002] In the busy port operation environment, loaders and excavators, as indispensable main machinery, undertake crucial tasks such as cargo stacking, high-platform operation, and loading. These operation links have extremely high requirements for the performance of the engine, and the state of the intake system is particularly crucial. In order to ensure that the engine intake system can operate under the best working conditions, it is particularly necessary to design an efficient air filter that adapts to the special port operation environment.
[0003] However, the cyclone filters or oil bath air filters fixed by traditional brackets commonly used in the current port mobile machinery engine intake systems have a series of obvious disadvantages:
[0004] First of all, the filtering effect of the cyclone pre-filter is not ideal. Most port mobile machinery adopts a two-stage filtering mode combining an air pre-filter and internal and external air filter elements. However, affected by the port operation environment, the dust collector of the pre-filter needs to be cleaned frequently in the engine intake system. In addition, due to factors such as dust and rain, the cyclone cover is prone to dust accumulation, further increasing the cleaning difficulty. Under this intake system, the service life of the main air filter and the safety filter is usually short, about 200 hours, resulting in relatively high maintenance costs.
[0005] Secondly, the oil bath air filter installed by the traditional bracket has a high failure rate in actual applications. Since machinery such as loaders and excavators often tilt during operation, and the oil filter bracket does not have an automatic leveling function. This causes the oil level of the oil bath air filter to tilt during slope operation, and the oil flows into the supercharger, intercooler, and combustion chamber of the engine along with the high-pressure air flow to participate in engine combustion. Since a large amount of dust is mixed in the oil, after entering the engine combustion, it will cause rough working conditions, and then exacerbate the wear of components such as intake and exhaust valves, piston rings, and cylinder liners, greatly reducing the service life of the engine. Once the oil enters the intake system, in order to keep the engine running normally, it is necessary to clean components such as the supercharging pipeline and the intercooler, which undoubtedly increases the maintenance cost of the equipment.
[0006] Finally, due to the poor effect of the traditional two-stage filter and the inability of the oil filter installed by the ordinary fixing method to be applied normally, the alarm of air filter blockage failures occurs frequently. These problems seriously affect the power output of the engine, increase the mechanical failure rate, and may even lead to production interruption. Summary of the Invention
