Description
Technical field
Compressor arrangement is the utility model is related to, more particularly to a kind of compressor.
Background technology
Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to gases at high pressure, is the heart of refrigeration system
It is dirty.Compressor generally comprises main casing and reservoir, is connected between reservoir and main casing by air intake duct group, to cause liquid storage
Refrigerant in device can be flowed into main casing and is compressed in the cylinder of installation, and the high-temperature high-pressure refrigerant gas after compression passes through
Blast pipe is discharged, so as to realize the kind of refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).
It is high temperature and high pressure gas in the main casing of compressor in refrigerative circle system, and air intake duct group is tightly connected all the time
Reservoir and main casing, the heat of main casing are easy to conduct by the outer wall of air intake duct group low to air intake duct group internal flow
In warm gaseous coolant, suction superheat problem is caused.Research shows, suction superheat be influence compressor efficiency principal element it
One.In order to avoid the problem, a kind of compressor assembly is disclosed in existing patent (application publication number CN105221431A), its
In order to eliminate suction superheat problem, instlated tubular is set up in air intake duct group, for obstructing the heat of main casing into air intake duct group
The conduction of the gaseous coolant of portion's flowing.However, this cause the subregion of air intake duct group be formed as four layers of body (instlated tubular, in
Between pipe, the discharging tube of conduit and reservoir) nested structure, it is complicated, be unfavorable for manufacturing.Also, in air intake duct group
It is easy to occur due to leakage caused by failure welding during pipe welding.
Therefore, on this basis, existing solution is to use middle instlated tubular, i.e., by instlated tubular and intervalve with one
The body that root has effect of heat insulation substitutes, to simplify the structure of air intake duct group.But during practical set, on main casing
The presence difference in height being difficult to avoid that between the pipe axis height of conduit and the axially bored line height of the suction hole of the cylinder in main casing,
The discharging tube of reservoir stretches into from conduit, and keeps axis to overlap with conduit, then the pipe axis of discharging tube and the suction hole of cylinder
Axially bored line between necessarily lead to deviation, and the both ends of middle instlated tubular need to be tightly connected suction hole and the discharge opeing of cylinder respectively
Pipe, therefore, instlated tubular has good flexural deformation energy among the hole axle deviation requirement between discharging tube and the suction hole of cylinder
Power, to adapt to above-mentioned installation deviation, but in fact, the high material of low thermal conductivity, intensity often crooked deformability is poor, in
The selection of interval heat pipe is difficult to take into account heat-insulated, installation strength and the aspect of crooked deformability three.
To sum up, existing air intake duct group structure is further improved.
Utility model content
The purpose of this utility model is to overcome above mentioned problem existing for prior art, there is provided a kind of compressor, the pressure
Contracting machine can be with relatively simple air intake duct group structure, while the problem of compressor air suction overheats is improved so that cylinder
When height tolerance between suction hole and conduit be present, middle instlated tubular can be installed correctly, and misalign the material of interval heat pipe
Material proposes too high bending property requirement.
To achieve these goals, the utility model provides a kind of compressor, including main casing and reservoir, the main casing
