Having a good air filter has a significant impact on the performance and longevity of an automobile engine. Doing a good job in the daily maintenance of the air filter can not only prevent the engine from experiencing abnormal wear, but it can also significantly extend the life of the engine and the air filter. Life expectancy of a service. A brief introduction to the classification and structure of air filters, as well as the cleaning frequency and cleaning methods, as well as the proper replacement and installation methods of dry air filters for small excavators, is provided, and potential maintenance misunderstandings and misunderstandings are analyzed as a result. As well as presenting the most appropriate and effective maintenance methods. The engine's air intake system is incomplete without a properly functioning air filter mini excavator supplier. As a result, it is capable of separating dust that enters engine air to the greatest extent possible, which helps to prevent premature wear of engine cylinders, pistons, and piston rings. A malfunctioning air filter will result in an insufficient amount of air being drawn into the engine, insufficient combustion, a reduction in power, black smoke, and even scrapping. This will not only have an impact on the engine's power and economy, but it will also have an impact on the environment. Emissions from automobile engines pollute the environment. As a result, proper maintenance of the air filter is extremely important in order to ensure the stable and reliable operation of the engine, as well as the stable and reliable operation of the entire machine.
1 Introduction to the air filter in brief
Currently, air filters commonly used in diesel engines can be classified into two types: dry and wet. The difference between the two is whether the air is oiled or not. Wet air filters are currently used in agricultural machinery and small and medium-sized mining machinery due to the limitations of their own application; however, dry air filters are gradually replacing wet air filters in construction machinery such as small excavators, particularly in China. The majority of small excavator manufacturers primarily employ rotating dust-collecting dry dual-core air filters in their machines. The purpose of this article is to explain the most common maintenance misunderstandings and the proper maintenance methods for rotating dust-collecting dry dual-core air filters for small excavators (hereinafter referred to as dry air filters) in detail.
1) The dry air filter's chemical composition
The dry air filter is primarily composed of a shell, a safety filter element (also known as an inner filter element), a main filter element (also known as an outer filter element), an end cover, and a dust exhaust valve. The safety filter element is also known as an inner filter element. It is common to use dry air filters because of their numerous advantages, including ease of installation, high filtration efficiency, large ash holding capacity, low environmental pollution, and ease of maintenance.
2) The dry air filter's operation is explained in detail here.
Pre-filter device (located between the housing and the main filter element) for the dry air filter, which can cause air entering the air filter to generate a swirling flow, which, due to the action of centrifugal force, will separate heavier dust particles from the intake air and deposit them in the dust valve. The high-performance dry air filter has a pre-filtering capacity of more than 85% and only allows less than 15% of the dust to pass through to the second-stage filter area (main filter element). Under normal conditions hydraulic breaker, the filtration efficiency of the main filter element can reach levels comparable to those observed in the industry. More than 99.9% of the time. In addition to the main filter element, there is a first-level safety filter element contained within it. Under normal circumstances, the pre-filter and the main filter element of the dry air filter are responsible for the majority of the dust removal from the air. Only when the main filter element is improperly maintained, poorly sealed, or damaged does the safety filter element fail to function. The engine can be protected by using a safety filter. When compared to the main filter element, the safety filter element has a higher permeability, a lower flow resistance, and a lower filtration efficiency than the main filter element. It will have no effect on the overall filtration efficiency and will only provide a protective layer of protection. As a result, it is not permitted to start the engine when only the safety filter element is present.
2 Common dry air filter maintenance misunderstandings, as well as proper dry air filter maintenance techniques
It is common for people to overlook the importance of daily maintenance of the dry air filter, which has a significant impact on the engine's life, power, and economy. Besides affecting the filtration efficiency and life of the air filter, this will also allow dust to enter the engine, causing wear and tear on the engine's internal components. The following are some of the most common misunderstandings and correct maintenance methods when it comes to the daily maintenance of dry air filters.
