Abstract
The invention discloses a heat-insulating and shock-absorbing coil pipe component applied to a refrigerating compressor. The coil pipe component comprises an inner air exhaust coil pipe, wherein one end of the inner air exhaust coil pipe is riveted on an air exhaust silencing cover; the other end of the inner air exhaust coil pipe is connected to a housing; and an heat-insulating and shock-absorbing sleeve pipe layer is coated on the inner air exhaust coil pipe. The coil pipe component has a simple structure, is convenient to form and process, and achieves a good heat insulation effect and a good shock absorption effect.
Description
(1)Technical field: the present invention relates to the parts of refrigeration compressor, specifically is a kind of adiabatic damping coil pack that is applied to refrigeration compressor.
(2)Background technology: refrigeration compressor moves reciprocatingly in cylinder block cylinder hole through piston, thereby realizes air-breathing, compression, the exhaust of refrigeration compressor, the cyclic process of expansion.The efficiency of compressor and noise are its key parameters.Interior exhaust coil pipe is used for being connected of exhaust noise silencing chamber and the outer pipeline of housing, be the refrigerant vapour of HTHP owing to what discharge, so air-flow is bigger to the impulse ratio of coil pipe, and airstream vibration is the main source of high frequency noise.At present mainly at coil pipe vibration larger part, promptly the middle part of the coil pipe damping spring that installs certain-length additional comes absorbed oscillation, reduces noise.But coil arrangement is complicated, and the artificial suit of damping spring is inconvenient, and efficient is lower.Because the coil pipe and the damping spring that adopt are metalwork, no heat insulation capacity, radiations heat energy is remarkable in housing, has increased the enclosure interior temperature, has reduced compressor output to a certain extent.
(3)Summary of the invention: the object of the invention improves exhaust coil arrangement in existing exactly, provides a kind of simple in structure, and machine-shaping is convenient, the adiabatic damping coil pack that is applied to refrigeration compressor of adiabatic good damping effect.
The internal exhaust coil arrangement of the present invention improves, and two kinds of schemes are specifically arranged.
Scheme one: be applied to the adiabatic damping coil pack of refrigeration compressor, exhaust coil pipe in comprising, said interior exhaust coil pipe one end is riveted on exhaust noise silencing and covers, and the other end is connected in housing; Its improvements are: the exhaust coil pipe is coated with the adiabatic casing layer of an ability in described.This adiabatic sleeve pipe also can reduce shock effect.
Described casing layer is the sleeve pipe that NR (natural rubber), SBR (butadiene-styrene rubber), BR (butadiene rubber), CR (neoprene), EPDM (ethylene propylene diene rubber), Q (silicon rubber) or PU (polyurethane) material are processed, and directly wraps to attach to be sleeved on outside the described interior exhaust coil pipe.
Described casing layer should coat all the other the inside exhaust pipe parts except that the required welding portion of technology.
Scheme two: be applied to the adiabatic damping coil pack of refrigeration compressor, exhaust coil pipe in comprising, said interior exhaust coil pipe one end is riveted on exhaust noise silencing and covers, and the other end is connected in housing; Its improvements are: the exhaust coil pipe is coated with the casing layer of the adiabatic damping of an ability in described.
Described casing layer is the formed coating of exhaust coil pipe outer surface in PU coating is coated in.
Described coating is coated in interior exhaust coil pipe middle part and forms one and is coated with interval, and coating layer thickness is 1-3mm; Interior exhaust coil pipe exposes 5-15mm and 25-45mm respectively and forms naked section with an end of exhaust noise silencing lid riveted joint and an end that is connected with housing; Be coated with between interval and the naked section with the transition of R arc.
In the such scheme one; The sleeve pipe that adopts NR, SBR, BR, CR, Q, EPDM modified rubber material to process replaces traditional carbon steel wire damping spring, and coil pipe is covered by sleeve pipe, because the high-elastic characteristic of sleeve pipe itself; Absorbed partial vibration; Having alleviated maybe be because the improper coil pipe bump that cause of assembling, has improved coil pipe service life, has reduced noise.
In the such scheme two since casing layer be the coating that is painted on the coil pipe outer surface with PU coating; Improved the integral rigidity of coil pipe; Reduce its natural reonant frequency,, avoided the propagation of vibration to the external world simultaneously as the internal vibration of an effective absorbent assembly of inner elastomeric physical efficiency; Owing to being coated with interval and naked section, avoiding stress to concentrate and cause the coating damage to come off simultaneously with the transition of R arc.
Because the casing layer among the present invention program one, two all is to adopt polymeric thermal insulation materials; And these materials all have good thermal insulation; Effectively completely cut off the exhaust coil pipe to compressor internal radiation heat, its most of heat with high pressure draught outside coil pipe is discharged casing.Increase the outside heat conduction of enclosure interior, reduced the enclosure interior temperature, improved gettering efficiency and refrigerating capacity, improved the COP of compressor to a certain extent.
Therefore, the coil pack after improving can reach the purpose of adiabatic damping.
