Description
Technical field
The utility model relates to a kind of centrifugal compressor, and particularly with the centrifugal compressor of variable inlet guide vane and rotatable vane diffuser, it is applicable to constant voltage demand, wide flow operating range and the bigger operating mode of level import temperature variation.
Background technique
Usually, when the joint work of compressor and other device, the operating mode of compressor just be fixed on certain a bit on, the design conditions point that this point is exactly a compressor.But in real work, because the variation of customer requirements, the flow of gas or pressure can increase or reduce to some extent, and this just needs to change the performance curve of compressor, and the mobile working point is to satisfy the demands.For this reason, once adopted a kind of centrifugal compressor,, changed the angle of the preceding entry guide vane of impeller, and air-flow was produced prewhirl by regulating the method for entry guide vane with variable inlet guide vane.This regulating method owing to changed the energy head of centrifugal compressor, therefore, is applicable to the occasion that pressure and flow increase simultaneously or reduce simultaneously.But under the situation of constant voltage, its regulation range just is restricted.Also adopt a kind of centrifugal compressor with rotatable vane diffuser, by regulating the method for rotatable vane diffuser, change impeller rear blade diffuser intake geometric angle, it is long-pending to change the throat section, reduces the angle of attack, makes the translation of the compressor performance curves left and right sides.Therefore this regulating method is applicable to constant voltage and the bigger occasion of changes in flow rate because peak efficiency value and energy head are influenced not quite.When requiring to change pressure, its regulation range then is restricted.The centrifugal compressor of above-mentioned two kinds of forms because their regulation range all has certain narrow limitation, is difficult to be applicable to existing constant voltage demand, and wide flow operating range and the bigger occasion of level import temperature variation are arranged again, and Applicable scope all is restricted, function singleness.Shortcomings such as and the driving mechanism of the centrifugal compressor of these two kinds of forms all adopts gear transmission, exists complex structure, and part is made the precision prescribed height, and assembling difficulty is big.
Summary of the invention
The purpose of this utility model is to provide a kind of centrifugal compressor with variable inlet guide vane and rotatable vane diffuser, it can overcome the deficiency of prior art, can change the angle of the preceding entry guide vane of compressor impeller, air-flow is produced prewhirls, can change simultaneously compressor impeller rear blade diffuser intake geometric angle again, it is long-pending to change the throat section, reduce the angle of attack, thereby can enlarge Applicable scope, can be applicable to constant voltage demand and wide flow operating range and the bigger occasion of level import temperature variation.
Its solution is: inlet is connected with variable inlet guide vane at compressor impeller, and by air-intake guide vane, the driving mechanism that it stirs band pin runner by the trough of belt crank is connected with electric actuator through connecting rod and constitutes.And stir at the trough of belt crank that links to each other with connecting rod on the active rotating shaft of band pin runner driving mechanism and be connected with pointer, it is used with the scale plate that is connected on the compressor impeller inlet entry guide vane case, is used to show the sense of rotation of air-intake guide vane and the size of rotation angle.And be connected with rotatable vane diffuser in the compressor impeller outlet port, by diffuser vane, it is stirred trough of belt runner driving mechanism by band pin crank and is connected with electric actuator with connecting rod through connecting rod and constitutes.And the connecting rod that links to each other with the active rotating shaft of being with the pin crank to stir trough of belt runner driving mechanism is provided with pointer, it is used with the scale plate that is connected on the spiral case of compressor impeller outlet port, is used to show the sense of rotation of rotatable vane diffuser blade and the size of rotation angle.
Described trough of belt crank is stirred band pin runner driving mechanism by support that is connected compressor impeller inlet and connected active rotating shaft and the band pin runner of bringing mouthful guide vane into, and this active rotating shaft connects with band pin runner by connected trough of belt crank.Also be distributed with the driven spindle of bringing mouthful guide vane into that is rotationally connected with it on support, this driven spindle is connected by connected driven trough of belt crank and band pin runner again and constitutes.
Described band pin crank is stirred trough of belt runner driving mechanism by the dividing plate that is connected the compressor impeller outlet port, is connected with the active rotating shaft of trough of belt runner and band diffuser vane on it, and this active rotating shaft connects with the trough of belt runner by connected band pin crank.Also be distributed with the driven spindle of the band diffuser vane that is rotationally connected with it on dividing plate, this driven spindle constitutes with the connection of trough of belt runner by connected driven belt pin crank.
The utility model mainly is to be connected with variable inlet guide vane in compressor impeller inlet, and is connected with rotatable vane diffuser in the compressor impeller outlet port.Owing on compressor, adopt being used in combination of variable inlet guide vane and rotatable vane diffuser, can enlarge the Applicable scope of compressor, can be applicable to constant voltage demand, wide flow operating range and the bigger occasion of level import temperature variation.Because of the synchronization control of variable inlet guide vane and rotatable vane diffuser, maximum control adaptability can be provided with the energy consumption of minimum, so can enlarge the steady working condition scope of compressor, improve Economy.Under the condition that keeps constant voltage, only be 75-105% for its flow adjustment range of the centrifugal compressor that has only the one-level variable inlet guide vane, and the centrifugal compressor that adopts one-level variable inlet guide vane of the present utility model and one-level rotatable vane diffuser to combine, its flow adjustment range can be expanded as 60-110%.Simultaneously, because variable inlet guide vane adopts the trough of belt crank to stir the driving mechanism of band pin runner, and rotatable vane diffuser adopts band pin crank to stir the driving mechanism of trough of belt runner, so the structure tube is single, easy to manufacture, transmission accuracy is high, easy to operate.Can realize manually and automatically regulating of air-intake guide vane and diffuser vane.
