Importance of air filter

Everyone knows that the engine is the heart of a car, and the oil is the blood of the car. And do you know? There is also a very important part of the car, that is the air filter. The air filter is often overlooked by the drivers, but what everyone does not know is that it is such a small part that is very useful. The use of inferior air filters will increase your vehicle’s fuel consumption, cause the vehicle to produce serious sludge carbon deposits, destroy the air flow meter, severe throttle valve carbon deposits, and so on.We know that the combustion of gasoline or diesel in the engine cylinder requires inhalation of a large amount of air. There is a lot of dust in the air. The main component of dust is silicon dioxide (SiO2), which is a solid and insoluble solid, which is glass, ceramics, and crystals. The main component of the iron is harder than iron. If it enters the engine, it will aggravate the wear of the cylinder. In severe cases, it will burn engine oil, knock the cylinder and make abnormal noises, and eventually cause the engine to be overhauled. Therefore, in order to prevent these dust from entering the engine, an air filter is installed at the inlet of the engine’s intake pipe.

Function of air filter

Air filter refers to a device that removes particulate impurities in the air. When piston machinery (internal combustion engine, reciprocating compressor air filter, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter is composed of a filter element and a shell. The main requirements of air filtration are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance.

Honeycomb filter performance advantages

The filter element is a key component for filtration products and equipment, and even directly related to the filtration effect in various application scenarios. Although there are relatively many types of filter elements to choose from, not all filter elements can meet the requirements of industry applications. , It is necessary to reasonably distinguish the functional types of the filter element in order to make the best use of it. In fact, the performance of the honeycomb filter element is very advantageous. As a small-sized filter consumable, the stability provided by the filter can be very good. The filtration problem of the oil system, so the honeycomb filter element has been widely used in vehicles such as logistics trucks.
It is undeniable that the demand for filtration products and consumables is relatively large today. Only in the field of logistics and transportation, the air intake system and oil system of logistics vehicles such as logistics trucks, light trucks, and container heavy trucks are dependent on high-quality filter elements. , but in the actual application process, you will find that the honeycomb filter element is relatively mature in all aspects of filtration, and can effectively filter the particulate impurities in the engine intake air and oil, so it will be used in various complex vehicle conditions. Give full play to the advantages of stable and reliable performance.
Of course, trucks are often faced with various complex road conditions during driving, so only a single mode and a filter element with conventional functions are not fully competent. Regardless of the air intake system or the oil system, a little carelessness will be due to particulate impurities. Pollution leaves hidden safety hazards. At this time, the installation and application of the truck air filter can enhance the filtration capacity invisibly. In this way, neither the air nor the oil products will be polluted and cause safety hazards. Therefore, for the air filter There is no room for sloppy application of filtering.
It can be seen that although there are differences in specifications and models on the surface of the filter element, as long as it can play its due role in the matching application scenario, especially the truck air filter, it can affect the engine oil and air intake system. If the logistics vehicle maintenance engineers can pay attention to the regular maintenance and maintenance of the truck filter system, it can virtually reduce the driving safety hidden danger of logistics vehicles.

At the same time, the air conditioner filter also has the function of making the windshield not easy to atomize. . Air conditioning filter – generally requires 8000-10000 km to be replaced once in order to achieve the best effect. Misunderstanding: Most people think that the air conditioner filter works only when the air conditioner is turned on in summer; in fact, it is used to filter the air entering the car throughout the year. In order to protect your health, don’t ignore the effect of this small filter!

The role of the oil filter:
As a part of the internal combustion engine, it plays a very important role in the lubrication system. It can filter out impurities such as metal wear debris, carbon particles and colloids gradually produced by the engine oil and mixed into the engine oil during the combustion process. These impurities will accelerate the wear of moving parts and easily cause lubricating oil circuit blockage. The oil filter ensures the normal operation of the internal combustion engine, greatly improves the service life of the internal combustion engine, and also prolongs the service life of other components.

The role of the fuel filter:
The function of the fuel filter is to filter the fuel (gasoline, diesel) required by the engine combustion, to prevent foreign matter such as dust, metal powder, water organic matter, etc. clogged oil filter

Care and maintenance of Doosan excavator filter elements:
1. Daily maintenance: check, clean or replace the air filter element; clean the inside of the cooling system; check and tighten the track shoe bolts; check and adjust the back tension of the track; check the excavator air intake heater; replace the bucket teeth; adjust the excavator shovel Bucket clearance; check the front window cleaning fluid level; check and adjust the excavator air conditioner; clean the floor in the cab; replace the crusher filter element (optional).

2. After the new excavator works for 250 hours, the fuel filter element and the additional fuel filter element should be replaced; check the clearance of the excavator engine valve.

3. When cleaning the inside of the cooling system, after the engine is fully cooled, slowly loosen the water injection port cover to release the internal pressure of the water tank, and then water can be discharged; do not clean the engine while the engine is working, the high-speed rotating fan will cause danger; when cleaning or When replacing the coolant, the machine should be parked on a level surface; the coolant and corrosion inhibitor should be replaced according to the table.

Excavator filter elements are generally hydraulic oil filter elements. According to its function and filter material, it can be divided into excavator air filter element, machine filter element, liquid filter element and excavator diesel filter element. The excavator diesel filter is divided into two parts: coarse filter and fine filter. Excavator filter elements are installed to protect internal operating equipment such as excavator chassis, fuel tanks, and engines. The excavator diesel filter element is mainly to protect the engine, and the excavator filter element is generally installed before the engine. The impurities in the oil enter from the outside or are generated from the inside. It needs to be coarsely filtered and then finely filtered by the excavator to effectively filter the impurities in the oil and avoid damage to the engine such as scratches or corrosion. The excavator air filter is to filter out the impurities in the air to avoid the wear of the chassis and the oil cylinder caused by the impurities in the air. No matter what kind of filter element, it should be checked and replaced regularly to ensure the normal operation of the excavator.

The filter element is used to filter liquid or a small amount of solid particles in the air, which can protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a certain size filter screen, its impurities are blocked, and the clean fluid passes through the filter element. outflow. The liquid filter element cleans the contaminated liquid (including oil, water, etc.) to the state required for production and life, that is, to make the liquid reach a certain degree of cleanliness.
