Abstract
The invention discloses a recycling air inlet pipe component with a guiding function. The recycling air inlet pipe component comprises a main pipeline; a first annular pipeline and a second annular pipeline sleeve the outer side of the main pipeline; a first annular pipeline cavity and a second annular pipeline cavity are formed between the first annular pipeline and the main pipeline as well as between the second annular pipeline and the main pipeline; the first annular pipeline is connected with the second annular pipeline through an annular plate; ventilation holes are uniformly formed in the circle of periphery of the annular plate; an annular notch which is communicated with the second annular pipeline cavity is also formed in the side wall of the main pipeline; the annular notch is obliquely formed along the side wall of the main pipeline; an air inlet pipe is vertically arranged on the outer side of the first annular pipeline; and the air inlet pipe is communicated with the first annular pipeline cavity. According to the air inlet pipe component, a decompression structure formed by the parallel two-stage annular pipeline cavities is adopted, so that the structure is compact, and airflow loss is reduced while the pressure is reduced; the annular notch is obliquely designed, so that a guiding effect for the air flow is realized, and processing is convenient; and after recycling air flows into the main pipeline, the phenomenon that the pressure and the flowing angle of the recycling air cause adverse influence on the working efficiency of a supercharger compressor impeller is avoided.
Description
Technical field
The present invention relates to a kind of recirculation air inlet pipe fitting with leading role, belong to gas recirculation system field.
Background technique
Circuit pipe assembled is on gas engine between mixed gas admission line and pressurized machine, and be the last section pipe fitting before pressurized machine, namely mixed gas is by directly entering the compressor impeller of pressurized machine after this section of pipe fitting.
Existing recirculation air inlet pipe fitting is a joint welding special-shaped t-bend pipe, cannot to play guiding to confluxing of air inlet recycle gas, mixed function, namely be equivalent to before air inlet recycle gas directly leads to pressurized machine, remittance sprue is got on the compressor impeller of pressurized machine by the air-flow with certain pressure, like this, air-flow enters the angle of impeller and pressure can change, the shock of air-flow to impeller can be increased, affect the working efficiency of impeller, simultaneously, have and beat on impeller compared with the air-flow of strong pressure, clashing into the vibration caused also can be abnormal, and impeller is high-speed rotary turntable, long-term accumulated can produce harmful effect to pressurized machine.
Summary of the invention
For solving above technical problem, the invention provides a kind of recirculation air inlet pipe fitting with leading role, make recycle gas through two-stage circuit chamber decompression and inclination circular groove water conservancy diversion after, import again in sprue, the harmful effect avoiding air inlet recycle gas to cause impeller, ensure that the normal work of pressurized machine and the normal air inlet of gas engine.
Its technological scheme is as follows:
A kind of recirculation air inlet pipe fitting with leading role, comprise main pipeline, the first circuit side by side and the second circuit is arranged with outside described main pipeline, this first circuit and form the first circuit chamber and the second circuit chamber between the second circuit and main pipeline, connected by ring flat-plate between described first circuit and the second circuit, on this ring flat-plate, circumferentially a circle is evenly provided with opening, described main pipeline sidewall is also provided with the circular groove communicated with the second circuit chamber, this circular groove is arranged along main pipeline sidewall slope, described first circuit outside vertical is provided with suction tude, this suction tude is communicated with the first circuit chamber.Air inlet pipe fitting adopts the pressure reduction structure in two-stage circuit chamber side by side, compact structure, windage loss is reduced while decompression, after preventing recycle gas from importing sprue, circular groove inclined design, have leading role to air-flow, and be convenient to processing, the pressure avoided due to recycle gas causes harmful effect with the working efficiency of remittance angle to pressure booster blower impeller.
As preferably, the gradient of described circular groove is less than 20 °.The gradient of circular groove so designs and can play leading role to air-flow, and can reduce windage loss to greatest extent.
As preferably, described first circuit is identical with the diameter of the second circuit, and the length of the first circuit is greater than the length of the second circuit.Design like this, can make circulating air enter into the second circuit chamber smoothly from the first circuit chamber, ensure that the normal air inlet of sprue and the stable of air pressure.
As preferably, described first circuit is connected with welding manner with main pipeline with the second circuit.Be convenient to manufacture, and cost is lower.
As preferably, described suction tude and the first circuit are smooth circular sliding slopes.Design like this, ensure that the air inlet of suction tude is unobstructed.
Beneficial effect:
The recirculation air inlet pipe fitting with leading role of above technological scheme, reduce pressure step by step to air-flow in two circuit chambeies that sprue periphery is arranged side by side, ensure that normal flow area and the flow channel shape of sprue, being obliquely installed of circular groove has leading role to air-flow simultaneously, windage loss is reduced while decompression, avoid recycle gas to import after sprue due to the pressure of recycle gas and the harmful effect importing the working efficiency of angle to pressure booster blower impeller and cause, improve the operating life of pressurized machine, compact structure, be easy to manufacture, and cost is lower.
