Abstract
The utility model relates to a single-stage multi-segment Roots blower, which belongs to mechanical devices and comprises a blower casing, an oil tank and an impeller shaft in the blower casing, wherein the impeller shaft is in a two-segment or multi-segment integrated structure of an impeller. The utility model adopts inside grading compression without middle cooler, has the advantages of small occupation area, material cost reduction, easy assurance of assembly precision, low energy consumption and blower noise reduction, and the weight of the two-segment blower is just one third as heavy as that of the two-stage blower.
Description
Technical field
The utility model relates to a kind of root's blower, belongs to mechanical device.
Technical background
Root's blower extensively applies to industrial fields such as environmental protection, electric power, oil, chemical industry, grain conveying.The induced pressure that the separate unit root's blower can bear is lower, be generally less than 0.1MPa, when requiring induced pressure to surpass 0.1Mpa, all adopt the form of two roots blower series connection, but it is not enough that the two-stage blower fan of two typhoon machines series connection form exists, and shows: 1, two roots blower series connection forms, and the centre need be provided with cooler, cool off the leaving air temp of one-level, cause that the blower fan floor space is big, complex structure, consumptive material be many; 2, two roots blowers quite produce the noise stack with two noise sources, cause the fan noise height.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, provide that a kind of volume is little, consumptive material is few, the single-stage multistage roots blower that noise is low, its innovative point is many typhoons machine is designed to one, compress to reach mesohigh by interior segment section, specifically be achieved like this: single-stage multistage Roots blower, comprise the impeller shaft in the Blower Housing, fuel tank, Blower Housing, it is characterized in that impeller shaft is the linking body structure of two sections or multistage impeller shaft.The utility model adopts the internal classification compression, and impeller suitable and two or many simple fan impeller length sums make the inner high pressure-temperature air that forms of blower fan, produce moderate finite deformation in order to prevent the blower fan axle under high pressure-temperature, can strengthen the blower fan diameter of axle.；
Blower fan is inner to adopt segmentation to compress, back segment is more much higher than the pressure that leading portion bears, like this, the high-pressure air of back segment certainly will want some to be leaked to the previous stage section, in order to prevent to reveal, raises the efficiency, with two impeller housing outer side slots of intermediate connecting shaft jointing place in all set Sealing, Sealing can be a teflon, also can be the close material of other high-performance, guarantees the axle envelope that each is intersegmental.
Blower fan is owing to the working pressure height, and the fan temperature rise height in order to reduce the blower fan operating temperature, all is equipped with chilled water unit on Blower Housing and the fuel tank.
The utility model single-stage multistage blower fan adopts the internal classification compression, need not establish interstage cooler, and floor space, two sections blower fan weight have only 1/3 of two-stage blower fan, and cost of material reduces greatly, and assembly precision easily guarantees, less energy consumption, and fan noise reduces greatly.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Embodiment 1, two sections Roots blowers of single-stage, comprise the impeller shaft in Blower Housing (5), fuel tank (4), the Blower Housing (5), impeller shaft is two sections impeller shafts (1,3) linking body structure has groove with two impeller shafts (1, the 3) hull outside of intermediate connecting shaft jointing place, all set Sealing (2) in the groove, all be equipped with chilled water unit (6) on Blower Housing (5) and the fuel tank (4).
Embodiment 2, reference example 1, and the impeller shaft in the single-stage multistage Roots blower, Blower Housing (5) is the linking body structure of plurality of sections (more than two sections) impeller shaft.
Claims (4)
