The role of filter screen and filter element in excavator air filter element

We all know that the work of the excavator engine requires a lot of air, and the cleanliness of the air actually plays a crucial role in the work of the excavator engine. The excavator air filter is the only device that connects the engine and the outside air to filter. The air filter I have brought here is actually a product installed on the Kobelco 200 bar. Then today I mainly talk about its structure, use and materials, and then I will discuss it according to several common questions of excavator friends.

excavator air filter

There are two types of air filters

The first big piece is the filter, which I have already dissected out, protecting the outside and inside the net.

The second largest item is filter paper. In fact, there are generally four kinds of materials used in the air filter filter paper on the market. The first is the one that is now seen, that is, the fingerprint-resistant plate, and the second type of galvanized plate. The third type of electrolytic plate. The fourth tinplate. Let me talk about what is called tinplate. In fact, the scientific name of tinplate is also called tinplate. In fact, tinplate is more used on the canned fish and cat cans, the canned iron, because tinplate was imported from Macau at that time Yes, and the English name of Macau is also called tinplate, so it is directly called tinplate according to Chinese and English intentions. The best of these four materials is of course the fingerprint-resistant board that we have seen now, and the worst is tinplate.

Introduction to the structure and function of the filter

The filter is divided into an external network and an internal network, and the external network plays a protective role. When the engine is inhaling, a relatively large impurity may be inhaled from the air. When the large miscellaneous tree enters the air filter, it can avoid direct breakdown, so the installation of this layer of outer net plays a protective role. , so it is also called a safety filter.

The intranet is also known as the support network. The support net knows that the work of the engine requires a lot of air, and the air puts pressure on the air filter. One presses all around, so the inner protective net needs to support me so that it is not easy to be broken or compressed.

Introduction to the structure and function of the filter element

There are two main types of filter paper for air filters that are commonly used on the market.

The first is the wood pulp paper sandwiched with glass fiber.

The second is the cotton swab paper. The glass fiber here is actually the glass box position. The reason why glass fiber is added on the filter paper is to increase the water resistance of the filter paper. The better one is of course this kind of wood pulp paper sandwiched with glass fiber, and the other slightly worse may be cotton pulp paper, which is a material of filter paper, and its function will undoubtedly play a role. to a filtering effect. If it can play a good air intake while filtering, it is a woman with a good air filter. That third one. That is, the upper and lower PU glue. In many cases, this Pew glue will also be used for iron sheets on some machines. In fact, their uses are the same, but they are different according to the working environment and the machine.
