Description
Technical field
The present invention relates to a kind of fluid machinery, described fluid machinery has lower housing portion, from top, is inserted into composite members and housing top lower housing portion, described composite members comprises two opposed housing lid and the rotor with axle that is guided through these two housing lid, and described housing top surrounds composite members and is fixed on lower housing portion from top.
Background technique
Fluid machinery is for expanding or pressurized gas.During the air inlet therefore in the situation that of turbo machine with high pressure is directed to turbo machine and expand at that, release energy on rotor.Compressor again for by air or other gas compression to until 100bar or higher final pressure.At this, also can compress the rodent gas of not answering in entered environment.Correspondingly fluid machinery is sealed as, and its working gas can not or only outwards be spilt through the gap between axle and housing slightly.
Known a kind of turbo-generator installation that is arranged on the turbo machine in housing that has from GB 219 016 A.That the axle of turbo machine is arranged on is independent, be arranged on the bearing support in turbine casing external body and the housing of self.The supporting member of axle is by oil lubrication, and bearing oil is positioned at the inside of the bearing housing of bearing support.From the leaked steam of turbine cylinder and the radiation heat of turbine cylinder, can cause the less desirable heating of the bearing oil in the bearing housing of bearing support.In order to keep out this heating, GB 219 016 A arrange the protective cover screwing on bearing housing, and described protective cover correspondingly has water cooling plant.
Summary of the invention
The object of the invention is, propose a kind of fluid machinery, by described fluid machinery, can realize reliable shaft sealing.
This object realizes by this class fluid machinery of mentioning at the beginning, at least one in its middle cover have around the directed temperature control mechanism of axle for around the region of axle control the temperature of lid.Can resist the motion relative to each other causing due to temperature of lid and axle.
The present invention is from following viewpoint: fluid machinery loads with gas, and the temperature section ground of described gas is obviously different from the case temperature of fluid machinery.Therefore turbo machine for example loads with hot gas, and described hot gas expands in turbo machine.Correspondingly, compare with other element, some elements of turbo machine are heated more by hot gas.In when compression, can again occur that extremely cold gas is imported into and compressed, place, the place cooling housing that gas is being become a mandarin consumingly.Guiding according to working gas through fluid machinery, the different element of fluid machinery is cooling with different speed.This also relates to these two axial lids of housing, and described lid is with respect to axle quick and consumingly cooling or intensification relative to housing.
In the situation that axle is arranged in lid, shaft seal is arranged on axle and supports between described axial lid, for example labyrinth or fluid seal, have gap between the part of described shaft seal rotation on axle at it and the static part covering.If so cooling or thermogenic action is on sealing area, this causes the shortcoming at seal aspect so.
In order to ensure best sealing, gap should be as far as possible little, yet it must be just also enough large, to avoid element collision when axle is worked.If the lid around axle is cooling, so described lid shrinks gap is increased, and makes to seal variation.On the contrary, in the situation that lid heats up tempestuously, for example, at the gas of compressor, discharge in side, gap dwindles.For fear of collision, gap must be chosen as in this case, and make it is correspondingly enough large in the operating temperature of all permissions of lid.Sealing off gap must be sized relative to the earth thus, and this is unfavorable for good sealing.
This problem can and suitably determine by installation shaft well that in less machine the size of sealing off gap solves satisfactorily, and described problem needs more to expend to solve in large machine.Because the large size of lid mean for the temperature variation of every degree thermal expansion also corresponding be large, sealing off gap can be moved several millimeters in the situation that of the cooling 100K of lid.Such temperature variation realizes with the size of suitably determining sealing off gap with the good heat isolation by lid to realize the good difficult sealing of axle.
In addition, large machine is characterised in that, its lid sealing can realize via two or more sealing levels, and wherein inner level is compared and had larger diameter with outside level.At the situation lower cover of this structure, can axially outwards be pressed against Sealing with respect to housing seal.Certainly to make together with two lids of rotor and this to put in the bottom of housing as installation unit or composite members be necessary to this embodiment.
By the temperature control mechanism of lid, the lid of the large machine during operation temperature in the region around axle can be controlled as, gap is marginally changed when work, make described gap aspect its size, keep being similar to gap width best for sealing.Can abandon the heat the expending isolation of lid or isolate to expend keeping little.
Temperature control mechanism can be heating machanism and/or cooling mechanism.Suitable, it not only can be for cooling and can be used in heating.This is especially favourable in compressor, because the housing lid at suction port place comes the housing lid of cooling and exhaust ports to heat by the hot gas of discharging by the cold air entering in this compressor.By means of the temperature control mechanism of working in an identical manner aptly in these two lids, the housing lid at suction port place is heated and the housing lid of exhaust ports is cooled.
Fluid machinery can be decompressor, as turbo machine, or compressor, for example turbocompressor, particularly single shaft radial compressor.Composite members can also comprise other element except lid and rotor, for example movement-oriented equipment, the particularly guide device that becomes a mandarin.
In a favourable mode of execution of the present invention, temperature control mechanism is directed around shaft seal, and described shaft seal is arranged between lid and axle.Thus shaft seal can with around the protected less desirable temperature of avoiding from external action of mode, hot or cold.
Control the temperature of lid, the particularly temperature of the sealing area around axle of control lid, can realize in many ways.Can use heating coil, yet the electric power of described heating coil must be shielded well.It is also feasible using heating cushion, yet described heating cushion is must be well sealed and be withstand voltage.Especially advantageously, temperature control mechanism has the first temperature control passage in lid, and described the first temperature control passage is fluidly connected with temperature control liquid storage.Temperature control liquid can be taken to desired temperature and be directed to around axle or shaft seal with which, in this place, states temperature control liquid releasing heat or cold.
To the existence of this temperature control liquid, be necessary, described temperature control liquid can be any suitable liquid.Yet can use bearing oil as temperature control liquid, described bearing oil is provided for installation shaft, so bearing oil is for a plurality of objects, makes it possible to abandon another liquid memory and additional temperature control liquid mechanism.
Advantageously, temperature control passage directly to being worked in lid, directly flows through lid temperature control liquid according to length.Especially advantageously, temperature control passage is machined in the inner side of lid.Because this inner side is directly connected with working gas, so it is especially cold or hot, make lid play therefrom cooling or heating consumingly.If temperature control passageway machining is in the inner side of lid, this temperature control passage is offset the less desirable temperature impact of institute especially effectively so.Direct fluid equipment can be positioned on the inner side of lid, and described direct fluid equipment can be the guide device or go out to flow guide device of becoming a mandarin.
Of the present invention another preferred embodiment in, temperature control mechanism has the second outside temperature control passage that is arranged on diametrically the first temperature control passage.Can realize thus the especially gapless temperature shielding of sealing area.The second temperature control passage can directly be connected with the first temperature control passage, and through-flow carry out successively or separately that makes these two passages makes for example to realize parallel through-flow.
Suitable, temperature control passage is opened directed around axle annularly.If described temperature control passage is arranged in axial plane at this especially, ring must be opened so, to allow inlet and outlet.By this opening hereinafter referred to as the gap without temperature control passage of ring, heat or cold energy are enough diametrically from the region of the inside of outer inlet passage and then to shaft seal.For fear of this situation, further propose: the second temperature control passage is directed to around the first temperature control passage, make tangential gap without temperature control passage in the region of the first temperature control passage at radially outer by the second temperature control channel mask.
Lid region is more closely arranged on shaft seal, and its accurate temperature is controlled just more important.In order to realize this, advantageously, these two temperature control passages are connected to each other to, and make before temperature control liquid turns back in temperature control liquid storage, and first temperature control liquid flows through the temperature control passage of inner radial and flow into the temperature control passage of radially outer from that from temperature control liquid storage.
The less desirable heat of institute or coldly not only can enter into shaft seal from radially outer, and can enter in the axial direction.Therefore advantageously, there is the temperature control passage of difference in functionality, particularly function of shielding radially and axial function of shielding.When these two temperature control passages have in the cross section of rectangle and described temperature control passage one and in axial direction have another in longer stretched dimensions and temperature control passage and radially have longer stretched dimensions, can realize this two kinds of functions.In the situation that in axial direction longer stretched dimensions can realize shielding radially and in the situation that radially longer stretched dimensions can realize axial shielding.
Suitable, at the temperature control passage of radially outer, there is longer stretched dimensions in axial direction and there is longer stretched dimensions radially at the temperature control passage of inner radial.Be positioned at diametrically thus inner most region and can be avoided the hot or cold of guide device that become a mandarin by shielding most effectively.
In another favourable design proposal of the present invention, for the gas of shaft seal, supply with directed between two temperature control passages of temperature control mechanism diametrically.Thereby the gas that is directed to thus shaft seal can remain on and in desired temperature, keep good sealing.Shaft seal can be fluid seal gas effect or oil effect.Labyrinth is also feasible.
