Description
Technical field
The utility model relates to diesel engine component, particularly a kind of diesel engine air filter protective hat.
Background technique
Air-strainer is the device of the granulometric impurity removed in air.During reciprocating machine (internal-combustion engine, reciprocating compressor etc.) work, contain the impurity such as dust just by the wearing and tearing of aggravation part if sucked in air, so air-strainer must be equipped with.Air-strainer forms primarily of filter core, housing and protective hat.The major requirement of air-strainer is that filtering efficiency is high, flow resistance is low, can uses and service free continuously the long period.
The effect of diesel engine air filter is the impurity in filtered air.If without filtered air, there is small particle the inside, after entering intake duct, greasy dirt can be mixed and stick together piston or valve, cause valve to hit piston, the disconnected push rod in top or rocking arm, impurity enters the wearing and tearing that cylinder can accelerate cylinder, also can form carbon distribution in cylinder, cause detonation.Paper filter core air-strainer has higher filtering efficiency, and intake resistance is little, therefore, in, light duty diesel engine is used widely.But in use, after particularly working for a long time in dry, that dust density is large working environment, filter core, constantly by the blocking such as dust and greasy dirt, makes intake resistance constantly increase, and causes engine power decline, oil consumption increase and exhaust smoke to increase.Mainly operating environment difference and protective hat do not play due protective action by the plugging reason such as dust and greasy dirt to cause filter core.
Now, general diesel engine air filter protective hat is made up of air inlet sleeve pipe, vent board and cartridge type protective housing, vent board is ring, its inner circle is set on air inlet sleeve pipe, cylindrical and cartridge type protective housing are close to, air enters filter core from air inlet sleeve pipe after entering cartridge type protective housing by vent board again, and this diesel engine air filter protective hat only plays air inlet effect, does not play protective action in fact for filter core.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of diesel engine air filter protective hat, effectively block the dust in air, for air filter for diesel engine filter core provides one barrier, ensure the long-term continous-stable operation of air filter for diesel engine, thus reduce or avoid the probability of happening of diesel engine fault, improve diesel engine working life.
For realizing above-mentioned technical purpose, a kind of diesel engine air filter protective hat that the utility model proposes, it comprises air filter protective housing upper cover, outer cover, helical vent plate, air inlet sleeve pipe, Steel net, filter screen separator, wing nut and packing ring, bump is fixedly installed in the middle part of described air inlet sleeve pipe, helical vent slab integral is ring, its inner ring to be set on air inlet sleeve pipe and spacing to it by the bump of air inlet sleeve pipe, and outer cover inwall is close in its outer ring; Ringwise, its inner ring is set on air inlet sleeve pipe filter screen separator, and filter screen separator is arranged on directly over outer cover inside, helical vent plate, and wire gauze filter is arranged in filter screen separator; Described protective housing upper cover has through hole, the enterprising gas port of air inlet sleeve pipe is fixedly installed screw rod, protective housing upper cover is close to and can just be covered outer cover, and air inlet sleeve pipe is connected with packing ring by wing nut with protective housing upper cover, and the enterprising gas port of described air inlet sleeve pipe is higher than the upper surface of Steel net.
Air enters filter core from air inlet sleeve pipe suction port again after being filtered by Steel net after entering outer cover by helical vent plate and carries out secondary, filters for three times.
Described outer cover entirety ringwise, its cross section similar inverted " recessed " shape, outer cover outer edge cross-section is large lower young frustoconic shape suitable for reading, outer cover inner ring presents the large frustoconic shape of young end opening, described helical vent plate outer ring is also fixedly installed annular backing ring, outer cover inner ring holds filter screen separator, and the annular backing ring outside helical vent plate is held on the downside of outer cover.
A kind of diesel engine air filter protective hat that the utility model proposes, effectively block the dust in air, for air filter for diesel engine filter core provides one barrier, ensure the long-term continous-stable operation of air filter for diesel engine, thus reduce or avoid the probability of happening of diesel engine fault, improve diesel engine working life.
