Description
Technical Field
The patent of the utility model relates to a diesel engine technical field, the high temperature resistant air cleaner who uses on the concretely relates to diesel engine air intake system.
Background
A large amount of fresh air is needed in the working process of the diesel engine, air in the operating environment of the diesel engine often contains various foreign matters, and the foreign matters can cause cylinder abrasion and other faults in the diesel engine cylinder along with the fresh air intake. The air filter can filter impurities and foreign matters in air, and ensures reliable work of the diesel engine, thereby prolonging the service life of the diesel engine. Therefore, an air cleaner is generally disposed in an intake port of an engine such as a diesel engine to filter foreign substances in fresh air.
With the continuous improvement of the rotating speed and the power of the diesel engine, the use requirements of the diesel engine applied to the fields of railway locomotives, marine ships and the like are also continuously improved; the operation environment of part of diesel engines is severe, the diesel engines and parts are in a high-temperature operation environment for a long time, and the reliability requirements of the diesel engines and the parts are high. The large-power diesel engine is large in size, the structural arrangement of the large-power diesel engine is limited by the application field, the arrangement position of the air filter is limited, and the large-power diesel engine can be in high environmental temperature, so that the high temperature resistance is a special requirement of the air filter in the application environment.
Air filters in the current market are various in types, a tubular dry-type paper air filter is generally configured for a high-power diesel engine, and the operating environment temperature is generally required to be 50 ℃; the diesel engine has high requirement on the reliability of the air filter under certain special high-temperature environments, the external temperature can reach 100-200 ℃, and a high-temperature resistant air filter is needed.
SUMMERY OF THE UTILITY MODEL
In order to solve the reliability problem of the air filter of the diesel engine in special application and meet the aim of reliable operation of the diesel engine under different environmental temperatures, the high-temperature resistant air filter for the diesel engine is designed.
The utility model adopts the following technical proposal to complete the invention task:
a high temperature resistant air filter for diesel engine, the high temperature resistant air filter has an air filter shell composed of an upper end cover, a lower end cover and an outer layer filter screen; a paper air filter element is arranged between the upper end cover and the lower end cover; the filter element of the paper air filter is a double-layer filter element; the outer side of the double-layer filter element is provided with an external protective filter screen, and the inner side of the double-layer filter element is provided with an internal supporting filter screen; the outside protection filter screen, inside support filter screen constitute and are used for carrying out the double-deck bearing structure that supports to the filter core, guarantee air cleaner high temperature environment operating stability.
The middle paper filter layer of the filter element is coated with a water-soluble resin layer on the upper surface and the lower surface.
The designed high-temperature resistant air filter for the diesel engine is characterized in that: the air filter sealant is a high-temperature-resistant hot melt adhesive, and meets the high-temperature-resistant requirement.
The designed high-temperature-resistant air filter for the diesel engine is characterized in that: the upper end cover, the lower end cover, the outer protective net and the inner supporting net of the air filter are made of galvanized steel sheet materials, and the requirement of high temperature resistance is met.
The beneficial effects of the utility model are that, the utility model discloses a high temperature resistant air cleaner for diesel engine adopts high temperature resistant air cleaner filter paper and high temperature resistant sealed glue, satisfies the high filtration requirement of air cleaner and simultaneously, adopts high temperature resistant material to improve the air cleaner reliability, and fresh air passes through high temperature resistant outer protection network and high temperature resistant filter paper gets into empty filter. The air filter of the utility model can meet the operation requirement of high temperature environment of 100-250 ℃, has simple structure, reasonable and effective design and higher product reliability.
