Embodiment
Referring to accompanying drawing, embodiments of the present invention are described.Fig. 1 is synoptic diagram when representing that the buffer rubber member 10 of one embodiment of the present invention is arranged at compressor 20.In addition, Fig. 2 is the II-II sectional view representing the compressor 20 shown in Fig. 1.
See figures.1.and.2, in the refrigerant circuit of compressed steam, compressor 20 is the rotary compressors for being used by the refrigerant compression of low pressure to high pressure.Compressor 20 comprises compressor body 21, accumulator 22, fixed component 23 and restraint zone 24, wherein, described accumulator 22 stores the refrigeration agent sucked by compressor body 21, described fixed component 23 fixes accumulator 22 to compressor body 21, and described restraint zone 24 presses accumulator 22 to fixed component 23.
When being transmitted the vibration that compressor body 21 when compressor 20 operates produces by fixed component 23, accumulator 22 will become the generation source of vibration and noise.Therefore, but make the buffer rubber member 10 as the material that shakes be wound in accumulator 22, and make it between accumulator 22 and fixed component 23.Thereby, it is possible to reduce result from compressor body 21 and by fixed component 23 to become vibration and noise generation source accumulator 22 transmit vibration.
As existing buffer rubber member 10, but be used as the EPDM of shake material and the low price be widely used.But the inside due to accumulator 22 is the drum in cavity, and its quality is less, therefore, when the vibration that compressor body 21 produces is passed, vibration and noise will amplify.And inventor is conceived in the buffer rubber member 10 using existing EPDM, and cannot fully reduce with the accumulator 22 included by such a compressor 20 is the vibration in generation source and the problem of noise.
Inventor, by repeatedly testing, determines using butyl rubber as buffer rubber member 10, produces at compressor body 21 and the vibration of being transmitted to accumulator 22 by fixed component 23 thereby, it is possible to fully reduce.
And then, determine by being used as a kind of halogenated butyl rubber of butyl rubber to form buffer rubber member 10, because its compression set is than IIR little of general butyl rubber, even if therefore Long-Time Service, be also difficult to cause falling down or tilting of accumulator.
And then, determine when butyl rubber comprises the tackifying resin making coefficient of losses improve, the vibration of transmitting to accumulator 22 can be reduced further.Will be described below about its detailed content.
Here, but but coefficient of losses refers to one of evaluation index of the characteristic of shaking of the material that shakes, the material that coefficient of losses is larger more reduces vibration.In addition, tackifying resin refers to more than one the resin selected from the group formed by abietic resin, terpene resin, petroleum resin, coal resin, phenolic resin and xylene resin.In addition, relative to the butyl resin of 100 weight portions, the content of tackifying resin is below more than 0 weight portion 100 weight portion.Preferably, below more than 0 weight portion 50 weight portions.
