In the present embodiment, gas-liquid separation component is set inside fluid machinery, gas-liquid separation is carried out to mixed state refrigerant,
It is provided with external gas-liquid dispenser outside fluid machinery, but does not limit whether fluid mechanical external is arranged external gas-liquid dispenser
System, when internal gas-liquid separation component can satisfy the gas-liquid separation demand of fluid machinery, can not use external gas-liquid liquid separation
Device.
As shown in Fig. 2, fluid machinery further includes shell 7, shaft 9, gas-liquid separation component and cylinder 12 are arranged at shell 7
Interior, the liquid after gas-liquid separation flows into the bottom of shell 7.Shell 7 is located at outside shaft 9, gas-liquid separation component and cylinder 12, with
Above structure is protected, prevents the impurity such as dust from entering to the normal operation in above structure and influencing fluid machinery.On
The structure for stating structure is simple, is easy assembly, realizes.Specifically, mixed state refrigerant carries out the mistake of gas-liquid separation in disengagement chamber 15
Cheng Zhong, the liquid after separation flow into the bottom that lower bearing 13 is formed by cavity 154 under Gravitative Loads, then will not influence fluid
Mechanical normal operation.
As shown in Fig. 2, gas-liquid separation component is located at the lower section of cylinder 12.In this way, separation after gas due to density it is smaller,
It naturally moves upward, cylinder 12 is arranged in the top of gas-liquid separation component, so that gas enters cylinder 12 more after separation
It is easy, does not need to increase additional pipeline gas is guided, so that fluid machinery internal structure is simpler, reduce
The processing cost of fluid machinery.Meanwhile the liquid after separation moves downward under its Gravitative Loads, the above-mentioned position of cylinder 12 is set
Setting can prevent liquid from entering in cylinder 12, and then guarantee the normal operation of fluid machinery.

Specifically, motor drives shaft 9 to be rotated, and drives roller 11 to rotate in cylinder 12, to realize cylinder 12
Air-breathing, compression and exhaust.Mixed state refrigerant carries out gas-liquid separation under the action of filtration members 16, and the gas after separation enters cylinder
In 12, the liquid after separation cannot pass through filtration members 16 and the bottom of inflow disengagement chamber 15.
Optionally, filtration members 16 are one layer or multiple filtration net, and when filter screen is multilayer, multiple filtration net is along fluid
Mechanical axis direction interval setting.
In fluid machinery operational process, the internal temperature of fluid machinery is higher, and lower bearing is immersed in high temperature grease,
17 temperature of lubricating oil to make to be wrapped in outside lower bearing 13 is very high, and liquid phase refrigerant is stored in lower bearing cavity, due under
Bearing is surrounded by high temperature grease, and liquid phase refrigerant is easy to gasify, and compressor internal high temperature lubricating oil further freezes liquid phase
Agent gasification, compressor gas-liquid separation ability greatly promote.Compared to enjoying external gas-liquid separator, the inside Separate System of Water-jet
The ability of gas-liquid separation is stronger, effectively prevents absorbing gas belt liquid in compressor operation, simultaneously because the inside gas-liquid separation
System has independent gas liquid separating function and liquid phase refrigerant storage effect, therefore the volume of rotor compression outboard portion liquid device can
It is even removed with opposite reduction, external dispenser external surface area is reduced, i.e., acoustic radiation area is reduced, and reduces making an uproar for compressor
Sound.
The working principle of the fluid machinery of the present embodiment is as shown in Figure 3: mixed state refrigerant is entered by air intake duct, lower bearing
Mouth 151 enters in lower bearing cavity 154, the gasification of gas liquid separating function and high temperature grease 17 through filtration members 16,
Vapor phase refrigerant flows through cylinder entrance 121 by the outlet 152 of lower bearing, to be compressed in cylinder 12；Liquid phase refrigeration
Agent is then stored in the cavity 154 of lower bearing.In the fluid machinery course of work, the gas liquid separating function and Gao Wenrun of filtration members 16
The gasification of lubricating oil 17 carries out simultaneously, therefore its separation liquid ability is stronger, effectively prevents air-breathing in compressor operation
Band liquid, avoids the damage of compressor pump part, since the inside Separate System of Water-jet has independent gas liquid separating function
It is acted on liquid phase refrigerant storage, external liquid separation body product can design smaller or even cancel, therefore the utility model reduces outside
Portion's dispenser outer surface acoustic radiation bring noise, effectively reduces the noise of compressor.
Present invention also provides a kind of heat exchange equipment (not shown)s, including above-mentioned fluid machinery.Optionally, it exchanges heat
Equipment is air conditioner.In the present embodiment, with gas-liquid separating function gas-liquid separation component be located at fluid machinery inside and
Together with the equal Standards of cylinder 12, and then reduce the noise source and vibration source of fluid machinery, reduces the vibration of fluid machinery
Moving noise and disequilibrium.In addition, the fluid machinery in the present embodiment reduces the vibration transmitting of heat exchanging equipment, heat exchange is reduced
The vibration noise of equipment.
In conclusion the fluid machinery of the utility model, constructs internal Separate System of Water-jet, increase a gas-liquid separation
Process and increase a liquid phase refrigerant storage chamber, can complete refrigerant air-liquid separation and liquid phase refrigerant storage and it is complete
It compresses, and further liquid phase refrigerant can be gasified by compressor internal high temperature lubricating oil at vapor phase refrigerant, strainer
The gasification of gas liquid separating function and high temperature grease carries out simultaneously, and gas-liquid separation effect greatly promotes, and effectively prevent compressing
Absorbing gas belt liquid in the machine course of work avoids damaging compressor pump because of absorbing gas belt liquid, improves compressor reliability, because of building
Internal Separate System of Water-jet, the system have independent gas liquid separating function and a liquid phase refrigerant storage effect, and compressor
The effect of external gas-liquid separator is equally gas liquid separating function and liquid phase refrigerant storage effect, so its volume can be opposite
Reduce and even remove, after the volume of gas-liquid separator is reduced, external surface area greatly reduces, i.e., radiated noise area is reduced, and has
Effect reduces compressor noise.
