Example Embodiment

[0013] The features and principles of the present invention will be described in detail below with reference to the accompanying drawings. The examples cited are only used to explain the present invention and are not intended to limit the protection scope of the present invention.

[0014] Such as figure 1 As shown, the high-pressure air-cooled Roots blower includes a casing, an impeller 1, a rotating shaft 2, a wall plate 3, an oil tank 4 and a gear 5.

[0015] The air inlet pipe and the air outlet pipe are respectively vertically welded and fixed on the outer peripheral surface of the casing, and the air outlet pipe and the air inlet pipe are coaxially distributed to make the flow of wind smoother.

[0016] Such as figure 2 As shown, the cross-sections of the inlet 6 of the air inlet pipe and the outlet 7 of the air outlet pipe are designed to be rhombus, which better ensures the concentration of air volume.

[0017] Moreover, the opening direction of the outlet of the air outlet pi...

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 [0001] The invention relates to the technical field of blowers, in particular to a high-pressure air-cooled Roots blower. Background technique [0002] The existing Roots blower has been widely used because of the superior performance of the design form of the three-blade composite rotor. However, when the impeller rotates at high speed, the rigidity of the impeller and the shaft is threatened, causing damage to the connection between the impeller and the shaft. Long-term operation will degrade the performance of the fan, and even the fan may be damaged and cannot be used. In addition, the noise reduction of the fan is also a problem that is generally concerned at present; the high-speed rotating shaft drives the gear to rotate, and the positioning between the gear and the shaft and the smooth operation are also aspects that need to be improved. Contents of the invention [0003] In order to overcome the problems in the prior art, the invention provides a ...
