Embodiment
To the technological scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiments that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 3, a kind of adjustable Diffuser gas compressor, comprise: housing 1 and Diffuser 2, described Diffuser 2 cooperations are arranged in housing 1, in described housing 1, be provided with synchronous circle 3, on described synchronous circle 3, be provided with multiple Rocker arm 4s, described Diffuser 2 comprises multiple adjustable guide vanes 5 and multiple fixed guide vane 6, the connection corresponding to multiple Rocker arm 4s of described multiple adjustable guide vane 5, an adjustable guide vane 5 in described multiple adjustable guide vane 5 is connected on link assembly 7, and described link assembly 7 is connected on final controlling element 8.
In addition, described Diffuser 2 also comprises backboard 9, and described multiple adjustable guide vanes 5 and multiple fixed guide vane 6 are arranged on backboard 9, and described adjustable guide vane 5 and fixed guide vane 6 connect to form guide vane.
In addition, described guide vane is Wedge blade and air-foil blade, and adjustable guide vane 5 has formed complete guide vane with fixed guide vane 6, and Diffuser 1 is divided into multiple independent diffusion passages with certain orientation.Thereby entering gas compressor, the air that fixed guide vane 6 makes to press impeller 12 to be pressed into flows to the corresponding speed of the shorter raising in passed by path gas compressor, regulate adjustable guide vane 5 can make the angle of guide vane approach the angle of the air motion that enters Diffuser, thereby avoid the formation of turbulent flow, make air-flow steadily pass through Diffuser, the incident of the gas being pressed into loss is dropped to minimum, postpone the arrival of surge simultaneously.
In addition, on described link assembly 7, be equipped with socket bar 10, on described socket bar, be equipped with rotating shaft 11, described rotating shaft 11 is connected with an adjustable guide vane 5 in multiple adjustable guide vanes 5, final controlling element 8 drive link assemblies 7, drive the adjustable guide vane 5 being connected with rotating shaft 11 to rotate by socket bar 10, simultaneously, because 5, remaining adjustable water conservancy diversion leaf is all enclosed 5 and links together with synchronizeing by Rocker arm 4, can realize the synchronous rotation of all adjustable vanes.
In addition, be also provided with and press impeller 12 in described housing 1, described pressure impeller 12 is positioned at the below of Diffuser 2.
The specific works principle of the utility model is adjustable Diffuser gas compressor is as follows: fixed guide vane 6 and the common composition guide vane of adjustable guide vane 5, Diffuser 2 is divided into multiple independently diffusion passages, makes to press the air that impeller 12 is pressed into move according to the path of guide vane defined when through Diffuser 2.And between guide vane and pressure impeller 12, there are enough spaces, can avoid the high cycle fatigue of impeller and the generation of noise.In the situation that there is no guide vane, will move by the path of logarithmic spiral through the air of Diffuser 2, the distance that arrives compressor passage is longer, gas compressor bad response; In the situation that having guide vane, due to the effect of guide vane, the air of process Diffuser 2, by moving along the path of restriction, has shortened the distance that air-flow is passed by, and has improved the responsiveness of gas compressor.The movement velocity V of the gas that pressure impeller 12 is pressed into is determined by radial velocity Vr and tangential velocity Vt, the direction difference that gas enters Diffuser 2 under the different rotating speeds of pressing impeller 12, the angle α of speed V and tangential velocity Vt changes with the variation of pressing wheel speed.When gas enters Diffuser 2 by the guide functions of guide vane, only just not turbulization and the incident loss according to the path motion of guide vane defined stably of air-flow in the time that the direction (being β angle) of its moving direction (being α angle) and guide vane is identical, the generation in advance of anti-Zhichuan shake.Adjustable guide vane 5 has just played the effect of ACTIVE CONTROL, by regulating the angle beta of adjustable guide vane 5, makes it under 12 different rotating speeds of pressing impeller, make angle [alpha] close to angle beta, makes incident loss be down to minimum, and air-flow is stably by Diffuser 2.
Be different from prior art, the utility model is adjustable Diffuser gas compressor, can improve gas compressor responsiveness, can make again air-flow steadily by Diffuser, and incident loss is minimum, can turbulization.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
