Abstract
The utility model relates to the screw air compressor that a kind of female rotor front end installs block additional, comprising: female rotor suction end bearing, casing, female rotor and the male rotor be meshed with female rotor; Also comprise: be placed in female rotor front end block; Described arrangement is enclosed within the suction end axle of female rotor by female rotor front end block; Female rotor front end block its uneven is directly close to the suction end spiral section end face of female rotor, and another smooth surface is adjacent to mutually with female rotor suction end bearing; Described female rotor suction end bearing axial restraint front end block, anti-stop block double swerve on rotor; Described casing fixes female rotor suction end bearing, plays the effect of fixing front end block; Described male rotor and female rotor carry out engagement driving, compress gas; The beneficial effects of the utility model are: due to the suction end dress block at female rotor, can improve the air quantity of compressor to a great extent, and reduce specific power.
Description
Technical field
The utility model relates to a kind of screw air compressor, particularly relates to this screw air compressor female rotor front-end architecture.
Background technique
Its superior performance of double-screw compressor, reliable, shake little, efficiency is high, is the Developing mainstream of world today's air compressor.
Now oil spout double-screw compressor commercially increases tightness between rotor by the oil of jet lubrication in pressing chamber, reduces gas and leaks.This kind of method can only solve the leakage between rotor, and can not solve the leakage of suction end rotor, affect the size of air quantity and specific power, this also has a great impact for compressor overall performance.
Fig. 1 is the structural representation of screw air compressor suction end rotor in prior art; In figure: female rotor suction end bearing 10, casing 20, female rotor 40, the male rotor 50 be meshed with female rotor.
Summary of the invention
The utility model technical issues that need to address there is provided the screw air compressor that a kind of female rotor front end installs block additional, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: female rotor suction end bearing, casing, female rotor and the male rotor be meshed with female rotor; Also comprise: be placed in female rotor front end block; Described arrangement is enclosed within the suction end axle of female rotor by female rotor front end block; Female rotor front end block its uneven is directly close to the suction end spiral section end face of female rotor, and another smooth surface is adjacent to mutually with female rotor suction end bearing; Described female rotor suction end bearing axial restraint front end block, anti-stop block double swerve on rotor; Described casing fixes female rotor suction end bearing, plays the effect of fixing front end block; Described male rotor and female rotor carry out engagement driving, compress gas.
Compared with prior art, the beneficial effects of the utility model are: due to the suction end dress block at female rotor, can improve the air quantity of compressor to a great extent, and reduce specific power.
Accompanying drawing explanation
Fig. 1 is the structural representation of screw air compressor suction end rotor in prior art;
Fig. 2 is the utility model structural representation;
Fig. 3 A is stop block structure schematic diagram in front end in the utility model;
Fig. 3 B is the A-A direction view of Fig. 3 A.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
From Fig. 2, Fig. 3 A, Fig. 3 B: the utility model comprises: female rotor suction end bearing 1, casing 2, female rotor 4 and the male rotor 5 be meshed with female rotor; Also comprise: be placed in female rotor front end block 3; Described arrangement is enclosed within the suction end axle of female rotor by female rotor front end block 3; Female rotor front end block 3 its uneven is directly close to the suction end spiral section end face of female rotor, and another smooth surface is adjacent to mutually with female rotor suction end bearing 1; Described female rotor suction end bearing 1 axial restraint front end block 3, anti-stop block double swerve on rotor; Described casing 2 fixes female rotor suction end bearing 1, plays the effect of fixing front end block 3; Described male rotor 5 carries out engagement driving with female rotor 4, compresses gas.
In the utility model, front end block 3 is arranged on female rotor 4 front end, and be wherein directly close to the suction end spiral section end face of female rotor for its uneven, another smooth surface is then adjacent to mutually with bearing, is compressed by block, guarantee that block can be close to rotor by bearing; Because the compressed side of helical-lobe compressor and suction side all exist leakage triangle, and the leakage area of suction side is much larger than compressed side, according to theory: suction side inter-tooth volume does not exist pressure reduction, it affects little on the efficiency of compressor and leakage rate, but reality still has impact, so the gas leaked from leakage triangle can be reduced at female rotor suction end dress block, improve capacity for wind and specific power.
The installation method that the utility model increases rotor block is:
First, public affairs, female rotor and bearing support are installed as usual; Secondly, block is arranged on female rotor suction end, block must be close to rotor; Then bearing is loaded in the female rotor bearing hole of casing; Then public affairs, female rotor are slowly loaded in casing, the block being contained in female rotor suction end can be adjacent to the rib of bearing, therefore when female rotor rotates because bearing edge guard is by block pushing down tightly, block can be followed female rotor and be rotated together; Finally, according to normal flow, remainder is installed.
