Compressor still can be run to stability and high efficiency, to meet the requirement of client；On the other hand, in daily use, casing 4 is improved
The antifatigue degree of air intake duct 2, to extend the service life of compressor and entire compressibility.
Specifically, as shown in Figure 1 to Figure 2, the preferred metal tube of casing 4, internal diameter are slightly larger than the outer diameter of air intake duct 2, outside
Diameter is slightly less than the bore of suction inlet, also, the inner wall of the outer wall of casing 4 and suction inlet welds, the one end of casing 4 far from shell 1
It is welded with the outer wall of air intake duct 2.In addition, the length for the pipeline section that air intake duct 2 protrudes into liquid storage chamber 3, which can be greater than casing 4, protrudes into storage
The length of pipeline section in sap cavity 3 might be less that the length for the pipeline section that casing 4 protrudes into liquid storage chamber 3, but for the ease of casing 4
It is assembled with air intake duct 2, the length for the pipeline section that air intake duct 2 protrudes into liquid storage chamber 3 is generally equivalent to the pipe that casing 4 protrudes into liquid storage chamber 3
The end face that the end face of one end that the length of section, i.e. air intake duct 2 protrude into liquid storage chamber 3 and casing 4 protrude into one end in liquid storage chamber 3 is flat
Together.
Preferably, as shown in Figure 1 to Figure 2, suction inlet be equipped with to 3 inner bending of liquid storage chamber concave edge 11, concave edge 11 with
The first packing groove 5 is formed between the outer wall of casing 4；Likewise, casing 4 is equipped with far from one end of shell 1 to 2 place side of air intake duct
The other side bending convex edge 41, the second packing groove 6 is formed between convex edge 41 and the outer wall of air intake duct 2.First packing groove 5
It is identical with the effect of the second packing groove 6, it is that the fill solder for filling solder, to ensure weld is full, improves welding
Quality.
Next, the present embodiment will be in the case of not increasing casing 4 and in the case of having increased casing 4, to air intake duct 2
Stress condition analyzed, increase the rigidity of air intake duct 2 to prove that casing 4 has, reduce the effect of stress suffered by air intake duct 2.
Fig. 3 is the force analysis figure of the air intake duct 2 in the case of not increasing casing 4, and Cong Tuzhong can visually see, and is inhaled
Tracheae 2 only the junction (at the A in Fig. 3) at it with suction inlet by stress σ.The external force size that known air intake duct 2 is subject to is
W, external force direction are perpendicular to air intake duct 2, and air intake duct 2 is exposed to the length of the pipeline section of the outside of shell 1 for L, outside air intake duct 2
Diameter is h, then can be calculated:
Fig. 4 is the force analysis figure of air intake duct 2 and casing 4 in the case of having increased casing 4, can be intuitively from figure
Find out, in addition to casing 4 in its junction (at the B in Fig. 4) with suction inlet by stress σ1In addition, air intake duct 2 is in itself and set
The junction (at the C in Fig. 4) of the one end of pipe 4 far from shell 1 is also by stress σ2.The external force size that known air intake duct 2 is subject to
For W, external force direction is perpendicular to air intake duct 2, and the length that air intake duct 2 is exposed to the pipeline section of the outside of shell 1 and casing 4 is
L2, the outer diameter of air intake duct 2 is h, casing 4 with a thickness of b, the length that casing 4 is exposed to the pipeline section of the outside of shell 1 is L1, and
And L1+L2=L can then be calculated:
Obviously, σ1< σ, σ2< σ, that is to say, that after increasing casing 4, either air intake duct 2 or casing 4, their institutes
The stress received is respectively less than air intake duct 2 and does not increase stress suffered when casing 4, this is sufficed to show that, casing 4, which has, increases air intake duct
2 rigidity, reduce the effect of stress suffered by air intake duct 2.
In addition, it is also found that the thickness b of casing 4 is to stress σ from above-mentioned formula1Size have an impact, and casing 4
It is exposed to the length L of the pipeline section of the outside of shell 11To stress σ2Size have an impact.
Based on this, stress σ1There are relationship as shown in Figure 5 between 4 thickness b of casing, therefrom can visually see,
The thickness b of casing 4 is bigger, stress σ1It is smaller, thus, in practical applications can the metal according to used in casing 4 yield strength come
Corresponding thickness is chosen, to obtain optimal effect.
Likewise, stress σ2The length L of the pipeline section of the outside of shell 1 is exposed to casing 41Between there are as shown in FIG. 6
Relationship therefrom can visually see, and casing 4 is exposed to the length L of the pipeline section of the outside of shell 11It is bigger, stress σ2It is smaller, but
In practical applications, it needs to fix using fixture when assembling with shell 1 due to air intake duct 2, in order to avoid casing 4 influences fixture
Connection, L1With L2Between usually require to meet following require:
L1≤2×L2。
Embodiment two
As shown in fig. 7, unique difference of the present embodiment and embodiment one is that air intake duct 2 is equipped with branched pipe 21, and divides
Branch pipe 21 is perpendicular to air intake duct 2.Since branched pipe 21 increases the load that air intake duct 2 is connected, thus, what air intake duct 2 was subject to
Irregular stress will be more serious, and therefore, for the air intake duct 2 with branched pipe 21, the effect of casing 4 will be brighter
It is aobvious.
Preferably, with the popularization and application of air injection enthalpy-increasing technology, the preferred increasing enthalpy pipe of branched pipe 21, increasing enthalpy pipe generally has two
A effect, first is that the delivery temperature of compressor under worst cold case is reduced, to ensure reliability；Second is that increasing cold under worst cold case
Matchmaker's flow improves greenhouse ability.
In addition to above-mentioned difference, other specific structures of the present embodiment are consistent in embodiment one, corresponding principle and skill
Art effect is also consistent, and details are not described herein again.
To sum up, the utility model embodiment provides a kind of liquid storage device, is covered by being arranged between shell 1 and air intake duct 2
2 rigidity of air intake duct of pipe 4, the liquid storage device is strong, not easy to break, not only contributes to compressor by adding vibration test, to meet client
Requirement, additionally it is possible to extend the service life of compressor and entire compressibility in daily use.
