Abstract
The invention relates to a high-pressure air-cooling roots blower. The high-pressure air-cooling roots blower comprises an enclosure, an impellor, a rotary shaft, a wall board, an oil tank and a gear. The high-pressure air-cooling roots blower is characterized in that an air intake pipe and an air exhaust pipe on the enclosure are respectively perpendicularly welded and fixed on the outer peripheral surface of the enclosure; the air exhaust pipe and the air intake pipe are coaxially distributed; the cross sections of the inlet of the air intake pipe and the outlet of the air exhaust pipe are rhombic; the opening direction of the outlet of the air exhaust pipe is vertically downward; the outlet of the air exhaust pipe is connected with a silencer; the impellor is fixedly connected with the rotary shaft integrally; the rotary shaft is connected with the wall board via a bearing; and the gear is a helical tooth synchronous gear. Further, the gear is connected with the rotary shaft in a key-free mode. The high-pressure air-cooling roots blower guarantees the integral rigidity of the blower and the rotary shaft, and can still run well under the running conditions of high pressure and high flow rate.
Description
Technical field
The present invention relates to blower fan technical field, particularly a kind of high pressure air cooling roots blower.
Background technique
Existing roots blower is used widely because have employed the design form superior performance of three leaf composite rotorss, but, when impeller high speed rotating, the rigidity of impeller and rotating shaft is just on the hazard, make the connection of impeller and rotating shaft that breakage etc. occur, long operation makes the hydraulic performance decline of blower fan, blower fan even also may occur and damage and cannot use.In addition, the noise of blower fan eliminates problem is also the problem generally received publicity now; The rotating shaft driven gear of High Rotation Speed rotates, and the location between gear and rotating shaft, running stability etc. are also the aspects needing to improve.
Summary of the invention
For overcoming problems of the prior art, the invention provides a kind of rigidity good, operating steadily, the high pressure air cooling roots blower that the life-span is long.
The present invention solves the technological scheme that its technical problem takes: a kind of high pressure air cooling roots blower, comprise casing, impeller, rotating shaft, wallboard, fuel tank and gear, it is characterized in that: the air intake pipe on described casing and air outlet tube are respectively perpendicular on casing outer rim side face, air outlet tube and air intake pipe coaxial line distribute, the cross section of described air intake pipe import and air outlet tube outlet is rhombus, and the opening direction of described air outlet tube outlet straight down, air outlet tube outlet is connected with silencing apparatus; Described impeller and rotating shaft are connected to one, and rotating shaft is connected with wallboard by bearing; Described gear is oblique-toothed synchronous gear.Further, described gear and rotating shaft are for be connected without key.
Further, Profile Connection is passed through in described gear and rotating shaft.
Further, described silencing apparatus and base are for being fixed as one.
Further, described fuel tank adopts aluminum alloy material.
To sum up, the beneficial effect of technique scheme of the present invention is as follows: by by impeller and the integral formula of pivot design, ensure that the rigidity of blower fan and rotating shaft entirety, under the operating conditions of high pressure, large discharge, blower fan still can well run.By gear and rotating shaft are adopted without key Connecting format, gear is located reliable, operate steadily, noise is low, intensity is high, the life-span is long.By by air intake pipe import and air outlet tube exit design being the reduction that rhombus better ensure that concentrating of air quantity and noise.
Accompanying drawing explanation

Fig. 3 is sealed structural representation of the present invention.
In figure: 1 impeller, 2 rotating shafts, 3 wallboards, 4 fuel tanks, 5 gears, 6 air intake pipe imports, 7 air outlet tube outlets, 8 bearings, 9 sealing configurations, 91 seal cartridges, 92 packings, 93 hermetically sealed cases, 94 flinger rings, 10 setting sleeves, 11 discs, 12 expansion sets.
Embodiment
Be described in detail to characteristic sum principle of the present invention below in conjunction with accompanying drawing, illustrated embodiment, only for explaining the present invention, not limits protection scope of the present invention with this.
As shown in Figure 1, this kind of high pressure air cooling roots blower, comprises casing, impeller 1, rotating shaft 2, wallboard 3, fuel tank 4 and gear 5.
Vertical solid welding is on the outer rim side face of casing respectively for described air intake pipe and air outlet tube, and air outlet tube and air intake pipe coaxial line distribution design, make the flowing of wind more smooth and easy.
As shown in Figure 2, the cross section of described air intake pipe import 6 and air outlet tube outlet 7 is designed to rhombus, better ensure that concentrating of air quantity.
And the opening direction of described air outlet tube outlet straight down, air outlet tube outlet is connected with silencing apparatus, and that runs under ensure that high pressure on the one hand is steadily reliable, also reduces the brought running noise that runs up to a certain extent on the other hand.
Described impeller 1 is connected to one with rotating shaft 2, substantially increases the rigidity of impeller and rotating shaft entirety, ensure that blower fan still can stability and safety run under the operating condition of high pressure, large discharge.Decrease the time of maintenance and inspection, improve Security.Meanwhile, also eliminate the movable connection structure of impeller and rotating shaft complexity, decrease the installation time, improve working efficiency.
Described rotating shaft 2 is connected with wallboard 3 by bearing 8, at bearing, adopts sealing configuration 9 between rotating shaft and impeller, as shown in Figure 3, comprise seal cartridge 91, packing 92, hermetically sealed case 93 and flinger ring 94, achieve good sealing, prevent the leakage of oil, the operating pressure of blower fan in guarantee.
Described gear 5 adopts accurate Hardened gear face oblique-toothed synchronous gear, ensure that the hardness requirement of gear, improves the stationarity of fan operation, reduce noise.
Further, described gear and rotating shaft are for be connected without key, and axis location is realized by setting sleeve 10, disc 11 and expansion set 12, and location is more reliable, run more steady, and noise is low, join strength is high, the life-span is long.
Further, Profile Connection is passed through in described gear and rotating shaft.
Further, described silencing apparatus and base are for being fixed as one, and compact structure, reduces the volume of complete machine.
Further, described fuel tank adopts aluminum alloy material, reaches good radiating effect.
Above-described embodiment is only the description carried out the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; relevant technical staff in the field, to various distortion of the present invention and improvement, all should expand in the determined protection domain of claims of the present invention.
