Embodiment
Below, based on accompanying drawing explanation embodiments of the present invention.
Fig. 1 is the plan view of the turbocompressor of an embodiment of the invention, and Fig. 2 is the side view of the turbocompressor of Fig. 1, and Fig. 3 is the plan view of the turbocompressor of Fig. 1.
The turbocompressor of an embodiment of the invention is so-called gear driven type turbocompressor.As shown in Figure 1 to Figure 3, this turbocompressor is to have the framework 46 consisting of foundry goods and in this framework 46, be provided with centrifugal first order compressor 5 and the two-stage type compressor of centrifugal high stage compressor 6.
This turbocompressor is by the output shaft 2 of the drive motor 1 as driving mechanism, by gearing 3, make the impeller High Rotation Speed of the first order and high stage compressor 5,6, thereby the air (gas) sucking is bestowed to kinetic energy, make efficiently the air sucking slow down and convert pressure to, thus, compress this air.In this turbocompressor, carry out the cooling isothermal compression that approaches in centre, thereby improve whole compression efficiency.
Drive motor 1 is so-called flange-type motor, by flange 1a, is fixed in framework 46.Running shaft 4 configures abreast with the output shaft 2 of drive motor 1, and is connected with output shaft 2 by gearing (booster engine) 3.End in drive motor 1 side of this running shaft 4, is provided with first order compressor 5.End at the opposition side of running shaft 4, is provided with high stage compressor 6.Running shaft 4 passes through gearing 3 transmission of drive force at central part, and at the distolateral impeller that first order compressor 5 is installed as drive motor 1 side, at another distolateral impeller that high stage compressor 6 is installed.
The first order and high stage compressor 5,6 are configured to, and in the surrounding that is installed on the impeller of running shaft 4, possess diffuser and volute chamber.The first order and high stage compressor 5,6 transfer the air (gas) attracting to be accelerated to radial outside at the central part of impeller by impeller high-speed rotary.Air through accelerating is slowed down by diffuser and volute chamber, and the kinetic energy of bestowing this air converts pressure energy to.
In gearing 3, gearwheel (master gear) is connected with the output shaft 2 of drive motor 1, accelerates rotation with the small gear (planetary pinion) of this gearwheel engagement, thereby to running shaft 4 transmission of drive force.
Fig. 4 means the sectional elevation of formation of framework of the turbocompressor of Fig. 1.
In framework 46, be separated into: as first and second cooling chamber 44,45 that guides the path of air; Be filled with the oil tank 60 of the required lubricant oil of bearing, the gearing 3 of running shaft 4; And venting baffler chamber (blow down container) 80.At the first cooling chamber 44 and the second cooling chamber 45, accommodate First Heat Exchanger (interstage cooler) 47 and the second heat exchanger (recoler) 48 for cooling-air.Framework 46, together with interior separation being become to the demarcation strip of the first cooling chamber 44, the second cooling chamber 45, oil tank 60 and venting baffler chamber 80, consists of integratedly foundry goods.Venting baffler chamber 80 holds venting baffler 82, and between the first cooling chamber 44 and the second cooling chamber 45 and oil tank 60.
And, as shown in Figure 1, in the side of drive motor 1, dispose suction pipe 7 and the filter by suction 8 of first order compressor 5.Filter by suction 8 is for preventing from sucking the device of the foreign matter of atmospheric air.In this turbocompressor, utilize first order compressor 5, from suction pipe 7, suck extraneous gas, this extraneous gas is by first order compressor 5 compression, and via the air flue portion of framework 46, as shown in Figure 4, from the entrance 44a of the first cooling chamber 44, deliver to the first cooling chamber 44 of framework 46.
The compressed air of delivering to the first cooling chamber 44 reaches 200 ℃ of left and right, but is cooled to 40 ℃ of left and right by First Heat Exchanger 47.By the cooling air of First Heat Exchanger 47, from the first cooling chamber 44, via outlet 44b and the conduit 9 of the first cooling chamber 44, delivered to high stage compressor 6.
In this turbocompressor, when compressed air is when the consumption of superfluous, the compressed air such as factory reduces than the intake of extraneous gas, the outlet pressure of compressor rises.And, when the detected force value of sensor that is arranged at compressor outlet portion when utilization exceeds predefined value, open bleed valve 83.Now, untapped compressed exhaust is sent in venting baffler chamber 80 with the conduit 81 of venting baffler chamber inlet 80a via the outlet 45b that connects the second cooling chamber 45.Delivering to the exhaust of venting baffler chamber 80 emits to extraneous gas from venting baffler chamber outlet 80b via being contained in the venting baffler 82 of this venting baffler chamber 80.Venting baffler 82 is on one side the exhaust of compression to be carried out to the exhaust of described compression is emitted in noise reduction on one side in venting baffler chamber 80 and by the flow velocity of exhaust being lowered reduce the device of noise of the air vent of turbocompressor.This venting baffler 82 is configured to has the structure that comprises baffler that the pressure loss is little, is pasted with the passage of sound absorbing material, and noise is suppressed.
In this turbocompressor, form other unit of this turbocompressor, control the flow of air suction control valve, control running, stop and the lubricated required oil supplying device of the control panel of control valve, bearing, gear and in order not make lubricant oil make the fume extractor etc. of the interior maintenance negative pressure of framework 46 all be arranged in framework 46 in order to realize save space to the outside leakage of framework 46.
In addition, in this turbocompressor, venting baffler 82 is contained in framework 46, thus, realize the reduction of number of spare parts, reached cheapization of manufacture cost, and can either comprise venting baffler, described turbocompressor can also be arranged on to narrow and small place.
In addition, in this turbocompressor, venting baffler chamber 80 is between the first cooling chamber and the second cooling chamber 44,45 and oil tank 60, and in addition, framework 46 consists of integratedly foundry goods, thus, can strengthen the erasure effect being produced by venting baffler 82.Compressed air, when emitting to atmosphere, reaches sound pressure level more than 120dB, still, can utilize this venting sound of 80 pairs of baffler chambers of venting to cover, and makes its decay, and can fully reduce the outside noise of turbocompressor.
When oil tank 60 being built in to framework 46 when interior, in the next door of first and second cooling chamber 44,45, produce heat exchange, lubricant oil absorbs heat from high temperature air, through cooling air, again heats up.When this phenomenon produces, need to increase the capacity of oil cooler, in addition, cause the decline of the compressor efficiency that the rising by air temperature causes.In this turbocompressor, it is suppressed that the temperature of the lubricant oil in oil tank 60 rises, and therefore, do not need to increase the capacity of oil cooler, in addition, also can not produce the decline of the compressor efficiency that the rising by air temperature causes.
Industrial application feasibility
The present invention be applicable to as the power source of factory or process with and the turbocompressor used, thereby be particularly useful for the turbocompressor that compactness, quietization have been realized in framework built-in venting baffler chamber.
