Description
Technical field
The utility model relates to a kind of compressor air intake apparatus, particularly relates to a kind of compressor inleting pipe assembly.
Background technique
Along with industrial expansion, wind-force obtains increasing application.Air compressor is as a kind of universal machine, and is relatively more extensive in China's commercial Application.In the air compressor product development and using, compressor operation is after a period of time, and air induction hose is inhaled flat phenomenon sometimes, and the reason that this problem produces is from many-side.
Compressor is when air inlet, and at first atmospheric pressure is near a barometric pressure in empty filter ingress, and extraneous fresh air is in case suck from empty filter core; Through air induction hose, pass through suction valve again, get into the compressor head intakeport at last; Because air flow causes the suction pressure loss, this moment, compressor inlet place pressure just was lower than a barometric pressure; Thereby make air induction hose produce vacuum, thereby can produce a kind of flat tendency of inhaling air induction hose.If according to traditional air induction hose Placement; Referring to Fig. 1, promptly directly through bending compressor suction valve 1 and empty filter 2 are coupled together, although in the rubber air induction hose carbon spring steel wires is arranged with air induction hose 3; But in its atm difference power; The self gravitation square, under flexural stress and the fatigue stress effect, air induction hose still might be inhaled flat and produced inefficacy.
It at first is the effect of atm difference power.Because the compressor operating environment is more abominable, empty filter is stopped up, and inhalation resistance increases, and the air-breathing crushing of normal empty filter is about 1500Pa; When the approaching obstruction of sky filter, promptly empty filter pressure reduction alarm switch is reported to the police, and crushing has reached 6000Pa at this moment; Add pipeline itself along journey and local pressure loss about 1000Pa, therefore the crushing of whole pipeline can reach 7000Pa, just air induction hose has born the degree of vacuum of 7000Pa; The inside and outside generation of air induction hose this moment 7000Pa pressure difference, thus can calculate differential pressure action power F1=Δ P * S, and wherein Δ P is a pressure reduction; S is a sectional area, if the latus rectum of air induction hose is DN=200mm, thus Δ P=7000; S=(3.14/4) * 0.22=0.0314m2 then can calculate F1=7000 * 0.0314 ≈ 220N, and is as shown in Figure 3.This pressure forces air induction hose to produce near the suction valve curved section and moves downward trend, causes the radially dislocation relatively of spiral carbon spring steel wires in the air induction hose, and passage is sharply diminished, and it is big that crushing sharply becomes, thereby it is flat to cause air induction hose to be inhaled.
Secondly self gravitation effect F2 also can not ignore, and is as shown in Figure 1.Because it is crooked and long that air induction hose moves towards; Self is a little relatively heavy; This gravity forces air induction hose to produce near the suction valve curved section and moves downward trend, add that there is a segment distance in its center of gravity line of action with respect to the suction valve axis, so its gravity can produce gravitational moment; Force the air induction hose curved section to produce serious warp tendency, cause air induction hose to be prone to inhale flat;
It then is the flexural stress effect.Because air induction hose by bending; Its bending part external lateral portion receives then compression chord of tensile stress inside part; Thereby the generation flexural stress causes the flexible pipe polyurethane layer to be prone to break, thereby causes air leak in hose; Dust and other graininess impurity all might suck compressor in the air, cause compressor head to be worn and torn too early.
Be the fatigue stress effect at last.Because it is more frequent that the factory's compressor that has adds unloading, it adds unloading and can cause air induction hose stretched and relaxed, and one inhales one exhales.Just air induction hose receives the effect of atm difference power once, is in the suction pressured state, does not have the effect of atm difference power once, is in free state.Mainly be since compressor when loading air inlet; Gas flow is bigger; This moment, the pressure loss was relatively just bigger; Cause air induction hose to produce bigger vacuum, will receive inside and outside atm difference power effect this moment, this pressure forces air induction hose to produce the trend that moves downward near the suction valve curved section; Air inflow is considerably less during unloading, does not almost have the suction pressure loss, so the air induction hose external and internal pressure is equal, does not have vacuum, does not receive the effect of atm difference power, returns to nature again.This fatigue stress causes the flexible pipe polyurethane layer to produce fatigue failure, and air induction hose produces gross distortion and distortion, thereby finally causes air induction hose gas leakage or inhale flat.
Also having traditional air inlet pipeline all is to lean on air induction hose self bending to realize that two axial lines becomes 90 degree directions to connect, and the air induction hose diameter is big more, and its flexibility is poor more; Necessarily require bigger bending radius; So, the pipeline setting of compressor will throw into question, and pipe should not be arranged; The pipeline lines are not smooth, move towards not attractive in appearance.
Those skilled in the art is devoted to research and develop a kind of flat suction tude assembly that can prevent to inhale.
The model utility content
The technical problem that the utility model will solve is in order to overcome in the existing technology, and compressor inleting pipe is inhaled the deficiency of flat phenomenon easily, and a kind of novel suction tude assembly is provided.
The utility model solves above-mentioned technical problem through following technical proposals:
A kind of suction tude assembly comprises suction valve and empty filter, and said suction valve is connected with connecting tube with empty filter, and its characteristics are that said connecting tube comprises connection hard tube and the connected flexible pipe that is connected.
Preferably, connect through a connection piece between said connection hard tube and the connection flexible pipe.
Preferably, said link is a clip.
