Description
Technical field
The invention belongs to Compressor Technology fields, specifically, the present invention relates to a kind of full envelope horizontal type scroll compressors.
Background technique
Screw compressor is mainly made of control section, motor part, compression section, and compression section has a pair of of whirlpool disk, whirlpool
The main compression process of rotation compressor is realized by whirlpool disk.Refrigerant is collapsed into high temperature and high pressure gas, high temperature and pressure gas by whirlpool disk
Body is discharged through the gas vent in fixed scroll, is discharged again through exhaust pipe after being passed to compressor inner space.Whirlpool currently on the market
Revolving compressor, there are two types of structure types.The first is high temperature and pressure cavity compressor: i.e. motor, whirlpool disk are largely all located at exhaust end
High-temperature and high-pressure cavity in.The disadvantage is that controller causes the motor component of controller to be easy overheat close to high temperature and high pressure environment
Damage；Or additional cooling device cooling controller is used, causing compressor, structure is complicated, occupies too many space, uncomfortable
For needing the motor compressor of small size.Second is low-temp low-pressure cavity compressor: i.e. motor, whirlpool disk are predominantly located in suction
In the low-temp low-pressure chamber at gas end.The disadvantage is that the low-temperature refrigerant of inlet end is heated by motor simultaneously in cooling controller, formed
Harmful invalid overheat causes compressor whole refrigeration capacity to reduce, reduced performance.
Therefore need to research and develop that a kind of space hold is small, controller can cool down effectively, does not generate harmful overheat now
Horizontal full envelope screw compressor.
Summary of the invention

Gas separating pipe 31 is respectively positioned in discharge chamber 30.The oil droplet gathered in oil-gas separation tube 31 under the effect of gravity will be along inner wall of the pipe
It flow in discharge chamber 30, is then delivered in the oil sump in 8 region of motor under the action of oil pump 28.
Referring to Figure 14 and Figure 15, as the improvement of the present embodiment, it is additionally provided on the casing 29 of 30 end of discharge chamber unidirectional
Check-valves 36.One way stop peturn valve 36 and opposite 29 inner wall of casing form accommodating chamber, and exhaust pipe 22 is connected to accommodating chamber；It is unidirectional to stop
Returning valve 36 includes valve plate 37 and valve block 38, offers venthole 39 on valve plate 37,38 one end of valve block is fixed in valve plate 37 and row
The opposite surface of air cavity inner wall, 38 other end of valve block are put up on venthole 39.Wherein, the level height of venthole 39 is higher than row
The level height of tracheae 22.Referring to schematic diagram 15, one way stop peturn valve 36 in a quiescent state, valve block 38 under the effect of gravity with
Valve plate 37 fits together, and valve block 38 will cover the venthole on valve plate 37 39.Referring to schematic diagram 16, in working condition
Under, high temperature and high pressure gas is entered by the venthole 39 on valve plate 37 by after the jack-up of valve block 38, is then discharged again via exhaust pipe 22
To compressor.The liquid refrigerants of 22 outlet end of exhaust pipe will enter in the cavity of one way stop peturn valve 36 in case of flowing backwards,
And valve block 38 can stop liquid refrigerants at this time, therefore liquid refrigerants cannot be entered inside compressor, effectively prevent liquid
State refrigerant flows back to inside compressor via exhaust pipe 22.
It is provided with 22 degree of 29 ends of casing of exhaust pipe as the improvement of the present embodiment referring to schematic diagram 1 and Figure 16 and also sets up
There is safety valve 40, safety valve 40 includes valve body 42, spool, air inlet 44 and gas vent 45；42 both ends of valve body be respectively arranged with into
Stomata 44 and gas vent 45, spool are set in valve body 42 between air inlet 44 and gas vent 45；Spool includes spring 46 and envelope
Blocking film 47,46 first end of spring are fixedly connected with plugging sheet 47, and 46 second end of spring is fixedly connected with cavity inside, plugging sheet 47
Close to air inlet.46 first end of spring is fixedly connected with plugging sheet 47, and 46 second end of spring is fixedly connected with cavity inside, is blocked
Piece 47 is close to air inlet 44.The diameter of plugging sheet 47 is greater than 44 diameter of air inlet.The first end and plugging sheet 47 of spring 46 are fixed
Connection, second end are fixedly connected with cavity inner wall.In slightly compressed state when spring 46 is placed in cavity, plugging sheet 47 is set
Close to one end of air inlet 44 in cavity, it is under the elastic deformation state of compression, plugging sheet 47 can be pushed up due to spring 46
Firmly it is adjacent to air inlet 44.The diameter of plugging sheet 47 is slightly larger than the diameter of air inlet 44, and is less than the internal diameter of cavity；Such plugging sheet
After 47 block air inlet 44, the high temperature and high pressure gas inside compressor is lower than the deformation power of spring 46 to the pressure of plugging sheet 47
When, high temperature and high pressure gas cannot open plugging sheet 47；Only when high temperature and high pressure gas pressure is more than the deformation power of spring 46,
Plugging sheet 47 can be opened to enter in cavity.When compressor works normally, the refrigerant of low-temp low-pressure enters in compressor from air inlet pipe
Portion, subsequently into high temperature and high pressure gas is compacted into the disk of whirlpool, subsequent high temperature and high pressure gas diffuses to motor region, and
Enter discharge chamber by oil-gas separation tube, then enters exhaust pipe via one way stop peturn valve and be expelled to outside compressor.Work as compressor
When inside is normal pressure (for example being lower than 5MPa) state, at this moment the pressure of compressor internal high temperature high pressure gas is relatively low, by
Plugging sheet, is withstood and is adjacent to air inlet, therefore gas will not enter safety valve by the elastic deformation effect of spring in safety valve
In；When pressure value inside compressor reaches elevated pressures state (such as 5MPa or more), high temperature and high pressure gas is to closure
The pressure of piece has been more than the elastic deformation power of spring, can open the plugging sheet connecting with spring, then high temperature and high pressure gas into
Enter spool, be discharged using gas vent, to reach self-relieving purpose.
By setting discharge chamber and oil-gas separation tube, the oil-gas separation efficiency of compressor is significantly improved, height is efficiently solved
The technical issues of warm high pressure gas takes lubricating oil out of；By the way that one way stop peturn valve is arranged, it effectively prevent outside exhaust outlet end
Liquid refrigerants flowed backward to inside compressor via exhaust pipe, improve the working efficiency of compressor, reduce the energy consumption of compressor；It is logical
Setting safety valve is crossed, is not vented when realizing compression normal operating conditions, is vented automatically in the case that compressor internal pressure is excessively high,
To guarantee the safety of compressor, safety valve structure is simple, is not easy blocking and high efficient and reliable.
