Construction machinery, which is an important part of the assembly industry, is an indispensable mechanical equipment for mechanized engineering construction. The filter, which is mainly used to filter gas and impurities through the relevant filter paper, usually refers to the engine parts or the filter of the car.
To a certain extent, for construction machinery, the filter plays a vital role, has an important impact on the actual performance of the construction machinery, and is related to the normal operation state of the construction machinery.
Then, in order to better ensure the efficient operation of the construction machinery, it is necessary to conduct in-depth research on the identification and selection of engineering machinery filters. Therefore, it is possible to scientifically and rationally select the filter most suitable for engineering machinery to improve the operating efficiency of the construction machine and highlight the application value of the filter in the construction machinery.
1. The main types of engineering machinery filters
At present, the commonly used filters for construction machinery mainly include: air, oil, and diesel filters. These three types of filters are collectively referred to as engineering machinery three filters.
To a certain extent, although they are different types, and the effects of practical applications are also different, they all have a common feature, that is, they are all used to protect the core components of engineering machinery, especially for the sports sub-zero. Component protection.
For example, air filtration, its performance has a direct impact on the actual economic and dynamic performance of engineering machinery engines. To a certain extent, the air filter with relatively good quality can effectively reduce the amount of ash entering the construction machinery engine, meet the actual intake requirements of the engineering machinery engine, and prolong the actual overhaul period of the engineering machinery engine.
According to relevant statistics, 75% of the wear and tear of the construction machinery in the early stage of the engine is closely related to the filtration effect of the air filter. A large amount of dust is suspended in the air, and the approximate size is 1-1000 um. If the dust exceeds 35um, the filter can be used to filter out it to ensure the economic and dynamic performance of the engineering machinery engine.
2. Identification and reasonable selection of the effectiveness of the micro-engineering mechanical filter
To a certain extent, these counterfeit engineering machinery filters are not substantially different in appearance from the engineering machinery filters produced by regular manufacturers. However, the price standard is far lower than the price of the formal manufacturer’s engineering machinery filter, or even about 1/3 of the regular manufacturer’s engineering machinery filter sales price.
These counterfeit engineering machinery filters have great differences in the manufacturing materials and processes from the actual engineering machinery filter standards and requirements, and cannot meet the load work requirements of engineering machinery filters. The quality is far lower than the engineering machinery filters manufactured by regular manufacturers.
Then, once these counterfeit construction machinery filters are put on the market and used, there will be no obvious problems in the short term, and if the time goes by, the internal problems will gradually appear, affecting the construction machinery engine. Dynamic and economical.
Generally good filter elements are always neat, the filter of the big brand is also white and glamorous in color. If the bad filter has no holes, the material is yellow, the mold is not well preserved, and the filter is sold on the market. The sample is a thousand picks, so I can’t see the problem.
In addition, based on the actual use of the filter, the core components of the equipment are usually involved, such as the crank-link mechanism inside the engine, the assembly of the cylinder liner and the fuel injection pump, as well as the valve components in the hydraulic system, the motor, Hydraulic pumps, etc. To a certain extent, the filter will directly affect the overall life cycle of construction machinery and equipment.
Therefore, it is necessary to strictly control the accuracy of the filter based on the control of the pollution wear, and try to select a filter whose size is close to the particle size of the actual moving sub-dynamic oil film of the component. This ensures that the high-precision filter internal motor, hydraulic pump, etc. can extend the actual life cycle, effectively remove the pollution jamming problem of the hydraulic valve, and effectively ensure the economic and dynamic performance of the engineering machinery engine. .
