As shown in Figures 1 to 7, increasing enthalpy passage 50 structural representation provided according to embodiments of the present invention, this increasing enthalpy passage 50 includes quiet dish and increases enthalpy passage the 51, first Moving plate increasing enthalpy passage 52 and the second Moving plate increasing enthalpy passage 53, in outside, compression refrigerant gas passes sequentially through the first Moving plate increasing enthalpy passage 52 or the second Moving plate increasing enthalpy passage 53 that quiet dish increases in enthalpy passage 51 and orbiter 30, eventually enters into the first compression chamber 41 or the effect of the second compression chamber 42 realization increasing enthalpy QI invigorating.First Moving plate increases the tail end of enthalpy passage 52 and the second Moving plate increasing enthalpy passage 53 and utilizes and can seal by screw-in sealing-plug 60.Quiet dish increases enthalpy passage 51 and increases the second intercommunicating pore 52b of enthalpy passage 52 or the 4th intercommunicating pore 53b alternate communication of the second Moving plate increasing enthalpy passage 53 along with the gyration of orbiter 30 with the first Moving plate, thus realizing under preset pressure ratio to the purpose of Gas-supplying enthalpy-increasing in compression chamber.
Specifically, the first Moving plate increases enthalpy passage 52 and the second Moving plate and increases enthalpy passage 53 and do not reducing on the basis of structural strength of orbiter 30, passage aperture can design relatively greatly, flow through drag losses herein reducing cold-producing medium.Wherein, the second radial passage 52c is towards the internal diameter direction of orbiter 30 to design, to facilitate processing.One end of this second radial passage 52c offers the first intercommunicating pore 52a connected with the first compression chamber 41, and the other end offers the second intercommunicating pore 52b connected with the first axial passage 51b.The aperture of the first intercommunicating pore 52a and the second intercommunicating pore 52b is not limit, and the position of the first intercommunicating pore 52a can be designed in distance scrollwork tooth wall 0.15mm to 0.2mm position, so will not be able to damage scrollwork tooth wall by cutter when processing the first intercommunicating pore 52a.This second radial passage 52c and the three radial passage 53c is through hole in the excircle direction of orbiter 30, therefore need to seal, the present invention adopts the sealing-plug 60 that can screw in be arranged on the end of close excircle of the second radial passage 52c and the three radial passage 53c, and coats screw thread glue when assembling and can realize sealing herein.Refrigerant gas fully enters in the first compression chamber 41 or the second compression chamber 42 after the first Moving plate increases enthalpy passage 52 or the second Moving plate increases enthalpy passage 53.The first intercommunicating pore 52a in the invention process example is opened in the scrollwork inwall place of orbiter 30, thus outside colder refrigerant injection being increased in the first compression chamber 41 that enthalpy to orbiter 30 inwall and fixed scroll 20 outer wall seals.In addition, in orbiter 30, it is additionally provided with the second Moving plate increases enthalpy passage 53, third connecting hole 53a is opened in outside the scrollwork wall of orbiter 30, it is achieved outside colder refrigerant injection increases enthalpy to the second compression chamber 42 of orbiter 30 outer wall and fixed scroll 20 inner wall sealing.
When orbiter 30 moves, quiet dish increases the second duty that enthalpy passage 51 is configured to have the first duty connected with the first Moving plate increasing enthalpy passage 52 and connect with the second Moving plate increasing enthalpy passage 53.
As shown in Figure 7 and Figure 8, the present embodiment carries out any instant of gyration at orbiter 30, increase enthalpy passage 50 to connect with one of them compression chamber, as shown in Figure 7, the outside colder refrigerant now stored in connectivity slot 51c enters in the second radial passage 52c by the second intercommunicating pore 52b, first intercommunicating pore 52a and first compression chamber 41 of the second radial passage 52c other end connect, and refrigerant gas eventually enters in the first compression chamber 41.And in the process, the second Moving plate increases enthalpy passage 53 and the first axial passage 51b is constantly in closure state.It is capable of two compression chambers by this connectivity slot 51c and alternately increases enthalpy QI invigorating incessantly.For the ease of the design of connectivity slot 51c, specifically, the first Moving plate is increased enthalpy passage 52 and the second Moving plate increases enthalpy passage 53 and is disposed side by side on orbiter 30.
Screw compressor also includes: sealing-plug 60, and the first Moving plate increases the port of enthalpy passage 52 and the second Moving plate increases and is provided with sealing-plug 60 on the port of enthalpy passage 53.So ensure that the first Moving plate increases the port of enthalpy passage 52 and the sealing property of the second Moving plate increasing enthalpy passage 53.
As shown in Figure 8, A represents second intercommunicating pore 52b movement locus on fixed scroll 20 end face, B is the 4th intercommunicating pore 53b movement locus on fixed scroll 20 end face, second intercommunicating pore 52b, the 4th intercommunicating pore 53b compliant scroll dish 30 do gyration together, so orbital radius corresponding to A, B is the same, movement locus direction is the same.Now, the second intercommunicating pore 52b and connectivity slot 51c is in correspondence position when just connecting, and the 4th intercommunicating pore 53b is in correspondence position when just separating with connectivity slot 51c.The connectivity slot 51c structure of the embodiment of the present invention is to realize uninterrupted injection increasing enthalpy in two compression chambers.Namely the second intercommunicating pore 52b from connect with connectivity slot 51c position move to separation point position time, the 4th intercommunicating pore 53b from connectivity slot 51c disconnected position to connecting position.Outside colder refrigerant is made to enter in the first compression chamber 41 only by the first intercommunicating pore 52a all the time or be entered in the second compression chamber 42 by third connecting hole 53a.The first compression chamber 41 and the second compression chamber 42 that this structure is constituted for the fixed scroll 20 and orbiter 30 with asymmetric molded line, owing to the pressure in synchronization two compression chamber is unequal, when compression chamber need not increase and work under enthalpy QI invigorating operating mode, cold-producing medium in the compression chamber of elevated pressures is leaked in the compression chamber of lower pressure without the enthalpy passage 50 that increases passing through to connect, cause cold-producing medium to pass through to increase the internal leakage of enthalpy passage, affect the compressor service behaviour when not increasing enthalpy.
As shown in Figure 9, the second compression chamber 42 that 42a is the invention process example increases enthalpy QI invigorating angle range, the first compression chamber 41 that 41a is the invention process example increases enthalpy QI invigorating angle range, two lines is increasing enthalpy QI invigorating angle range of the prior art below, it appeared that existing increasing enthalpy passage two compression chamber alternately increases to exist between enthalpy QI invigorating is interrupted angle range from figure.And increasing enthalpy passage 50 structure that the present embodiment provides can realize the QI invigorating to compression chamber maximum magnitude, improve compressor efficiency during Gas-supplying enthalpy-increasing under compressor worst cold case.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
