Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As Fig. 1, a kind of energy-efficient three-dimensional flow multistage centrifugal blower shown in Fig. 2 and Fig. 3, comprise casing 1, impeller sets 2 and main shaft 3, described casing 1 adopts vertical front cover, described casing 1 comprises front screen 4, backboard 5 and integration are every dish 6, described front screen 4 and backboard 5 are separately positioned on the two ends of integration every dish 6, described integration is provided with cooling water chamber 7 every dish 6 inside, described integration is formed every dish room 8 in the middle of dish 6, described impeller sets 2 is arranged in dish room 8, described main shaft 3 is arranged in the middle of casing 1 through the two ends of casing 1, described impeller sets 2 is arranged on main shaft 3, described impeller sets 2 comprises multiple impeller 9, described impeller 9 comprises front wheel disc 10, blade 11 and rear trochal disc 12, described blade 11 is arranged on rear trochal disc 12, described front wheel disc 10 is arranged on the front side of blade 11, described blade 11 is ternary blade.
Described front screen 4 is provided with relief opening 13, for discharging air.
Described backboard 5 is provided with suction port 14, for sucking air.
The two ends of described main shaft 3 are respectively arranged with bearing 15, for installing external equipment.
Described blade 10 comprises multiple and is arranged on rear trochal disc 12 equably, forms three-dimensional flow impeller together with front wheel disc 10.
Described impeller 9 is that aluminum alloy material casting forms, and light with traditional impeller phase specific mass, run more stable, efficiency is higher.
The bottom of described casing 1 is provided with base 16, for supporting whole blower.
Blower casing 1 of the present invention adopts vertical front cover, namely with after single-piece work, from left to right, from side to opposite side assemblying body piecemeal, in assembling process, blower fan is erected and vertically assemble, terminating then to set level, is exactly front cover between that and another part, after unit is set level, it is vertical that each front cover combined rolls off the production line on being, this sample loading mode can make blower stator weight decline to a great extent, and the casing of suction port 14 and relief opening 13 and intermediate clapboard can parts processings, and processing is simple.Bearing 15 can use ball bearing, grease lubrication, save petrol station, for blower be in operation installation, simple to operately to lay the first stone, because multiple impeller 9 is a rotor set, be in operation due to the independence of vertical front cover single impeller 9 single housing, intensifications different in gas boost process is isolated, thus the vibration produced because swell increment is different preventing case material to bring under different temperature conditionss and multiple impeller 9 operate in resonance, ensure that blower pulsations value is for minimizing, and promote the life-span of bearing 15.Owing to being vertical assembling, easier add impeller 9 and integrated plane sealing between dish 6, stopped the overflow section of the leakage flowing that dynamic and static gap is formed thoroughly, added the flow resistance revealing runner.Have necessarily to the reaction thrust of rotor due to the thrust caused of boosting because planar tooth sealing is in operation, blower is run more steady, rotor thrust all-moving surface is less, to thrust-bearing 15 to bear load less, blower is significantly promoted working life, and frequency of maintenance significantly reduces.
Rotor based on the blower of three-dimensional flow on the basis of two-dimensional current impeller, stream curvature of a curve and slope is taken into account, also to consider the change radially of entropy and merit simultaneously, set up new flow model, break through " along the periphery " constraint of flowing, design the i.e. curved but also single impeller 9 of the vane type line turned round by Theory of Three-dimensional Flowing.This impeller 9 must meet the predetermined flow parameter (flow, pressure) under lower-speed state time (3000rpm), again by higher level pressure ratio (join several impeller and reach rated pressure), so just can there be higher efficiency (78%) and the scope of wider variable working condition, when an impeller 9 does not reach required pressure, can increase by two, three until more.And there is no direct mechanical friction due to any one parts, so there is not the low frequency noise produced due to mechanical friction in it, because it rationally determines the flow speed value at each position of flow passage components, to avoid as much as possible in runner and desulfurization phenomenon appears in minimizing, reasonably have selected entering of each flow passage components, exit angle, avoid turning unexpected in runner and expansion, decrease the impact loss of fluid, scream so irrational in gas flow, liquid collision sound is all reduced, the running noises of blower is made to drop to less than 80 decibels, and increased substantially the whole efficiency of blower, and make exit gas temperature minimized.
Integration is provided with cooling water chamber 7 every dish 6 inside, and the water circulation in cooling water chamber 7 can cooling blower temperature, and thermal power transfer becomes kinetic energy, increases pressure, raises the efficiency, and reduces noise.In running, therefore sound is refracted at the interface of air and water, and does not import in air, simultaneously water and cell wall also same refraction go back and reach the effect of the sound that goes out.
This blower in use adopts VFC, when operating mode resistance or flow need change, adopts different frequencies that rotating speed is changed, abandons the loss in efficiency that adjustments bring, improve the adjustable type of flow and pressure, thus reach more energy-conservation object.
The invention has the beneficial effects as follows: energy-efficient three-dimensional flow multistage centrifugal blower of the present invention, simple to operate, convert traditional unitary or two-dimensional impeller to three-dimensional flow impeller, mechanical friction can not be produced in the process of running, reduce noise and energy consumption, improve the whole efficiency of blower, make efficiency be increased to 78%; Casing adopts vertical front cover, can the vibration values of minimized reduction blower, blower is run more steady, increases the service life, reduce frequency and the expense of maintenance; Integration can reduce the noise of whole blower further every the design of coiling, and does not need additional acoustic isolation facility, reduces costs, increase work efficiency.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
