Abstract
A kind of end cover structure of screw compressor, it includes that one is fixed by bolts to the disc end cover body of casing one end by Flange joint limit, the inner chamber of described end cover body makes the air collecting chamber of evagination, and is radially arranged the venthole of connected set air cavity on a side of end cover body；It is evenly equipped with at least five outer convex cylindrical with bolt hole on the flange of described end cover body respectively, the lateral wall of described end cover body is provided with a plurality of radial reinforced rib bar；It has simple in construction, rationally, it is simple to maintenance, beneficially compression efficiency carries high.
Description
Technical field
The utility model relates to the end cover structure of a kind of screw compressor, belong to screw compressor technical field.
Background technology
Screw compressor is that a kind of gas after piston compressor and helical-lobe compressor is put aside between volution trough
And utilize and rotate machinery that gas is compressed, because of its have that efficiency is high, volume is little, light weight, operate steadily and by extensively
It is applied in the fields such as refrigeration, air-conditioning and heat pump.This screw compressor is mainly by sealed enclosure, fixed scroll and dynamic vortex
Dish, drive shaft and the composition such as support and motor, fixed scroll and orbiter are both provided with vortex wall, and fixed scroll is fixed
It is arranged in casing, and orbiter is arranged on the drive shaft end bias axle head of lateral arrangement, and at orbiter end face
It is fitted with cross slip-ring；In the running, orbiter is subject to the driving of eccentric axle head and is retrained by cross slip-ring screw compressor,
Making the motion of plane circular shaft, the vortex wall of two dishes engages configuration in opposite directions, by reducing the multiple pressures being formed between mutual crimping successively
Contracting room, compression enters the fluid in screw compressor.But the screw compressor of said structure structurally there is also not at present
Rationally, essentially consisting in arranging of sealed enclosure, the gas compression efficiency causing screw compressor is not high enough.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art to exist, and provides a kind of simple in construction, rationally, just
End cover structure in the screw compressor that maintenance, beneficially compression efficiency improve.
The purpose of this utility model completes by following technical solution, the end cover structure of a kind of screw compressor,
It includes that one is fixed by bolts to the disc end cover body of casing one end, the inner chamber system of described end cover body by Flange joint limit
Become the air collecting chamber of evagination, and on a side of end cover body, be radially arranged the venthole of connected set air cavity.
As preferably: be evenly equipped with at least five outer convex cylindrical with bolt hole on the flange of described end cover body respectively,
A plurality of radial reinforced rib bar it is provided with on the lateral wall of described end cover body.
This utility model belongs to improvements over the prior art, and it has simple in construction, rationally, it is simple to maintenance, favorably
High is carried in compression efficiency.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model.
Fig. 2 is side-looking structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.Fig. 1, shown in 2, one described in the utility model
The end cover structure of screw compressor, it includes that one is fixed by bolts to the disc end of casing one end by Flange joint limit 1
Lid 2, the inner chamber of described end cover body 2 makes the most convex air collecting chamber 3, it is simple to by casing by the gas axle of scroll compression
To row to end cover side, and concentrate on described air collecting chamber 3, and on a side of end cover body 2, be radially arranged connected set air cavity 3
Venthole 4.The gas after compression can be picked out conveniently by connecting tube from this venthole 4.
Shown in figure, the Flange joint limit 1 of described end cover body 2 is evenly equipped with respectively at least five with bolt hole 5 outside
Convex cylindrical 6, the lateral wall of described end cover body 2 is provided with a plurality of radial reinforced rib bar, to strengthen the use intensity of end cover body.
