The object of the invention is to overcome the deficiencies in the prior art, a kind of freezer compressor air suction silencer that improves gettering efficiency is provided, this air suction silencer is simple in structure, design science is reasonable, can effectively reduce the negative pressure in muffler cavity, reduce compressor overall noise, improve the stability of compressor.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of freezer compressor air suction silencer that improves gettering efficiency, this air suction silencer comprises noise reduction cavity, silencing and damping pipe, suction port and air outlet, silencing and damping pipe is arranged in noise reduction cavity, in its this noise reduction cavity, shock resistance demarcation strip is set, this shock resistance demarcation strip is divided into one-level silencing and damping chamber and secondary silencing and damping chamber by noise reduction cavity, the volume ratio in this one-level silencing and damping chamber and secondary silencing and damping chamber is 1:1.6, suction port is arranged on noise reduction cavity one side lower part, silencing and damping tube inlet is corresponding in one-level silencing and damping chamber with suction port, the outlet of silencing and damping pipe is connected with air outlet.
And described suction port is broadening formation.
And described silencing and damping pipe is arranged in noise reduction cavity by fixing frame.
And described silencing and damping pipe is provided with pressure relief opening in secondary silencing and damping chamber.
And described pressure relief opening is two and is symmetricly set on silencing and damping pipe.
And, described silencing and damping pipe comprises inlet duct, the first reduction of speed bend pipe, the second straight tube, the 3rd reduction of speed bend pipe, the 4th reduction of speed bend pipe, the 5th straight tube and the outer pipe being linked in sequence successively, between the 3rd reduction of speed bend pipe and the 4th reduction of speed bend pipe, is provided with pressure relief opening.
Advantage of the present invention and beneficial effect are:
1, the freezer compressor air suction silencer of this raising gettering efficiency comprises noise reduction cavity, silencing and damping pipe, suction port and air outlet, silencing and damping pipe is arranged in noise reduction cavity, in its this noise reduction cavity, shock resistance demarcation strip is set, this shock resistance demarcation strip is divided into one-level silencing and damping chamber and secondary silencing and damping chamber by noise reduction cavity, the volume ratio in this one-level silencing and damping chamber and secondary silencing and damping chamber is 1:1.6, suction port is arranged on noise reduction cavity one side lower part, silencing and damping tube inlet is corresponding in one-level silencing and damping chamber with suction port, the outlet of silencing and damping pipe is connected with air outlet, the present invention is by the effect that the reasonable distribution of noise reduction inside cavity ratio is reached to balance pressure and reduce noise, by determining that the volume ratio in one-level silencing and damping chamber and secondary silencing and damping chamber provides space to the diameter that expands silencing and damping pipe, reduced the air-breathing pressure loss, thereby promoted efficiency.
2, silencing and damping pipe of the present invention comprises the inlet duct being linked in sequence successively, the first reduction of speed bend pipe, the second straight tube, the 3rd reduction of speed bend pipe, the 4th reduction of speed bend pipe, the 5th straight tube and outer pipe, between the 3rd reduction of speed bend pipe and the 4th reduction of speed bend pipe, be provided with pressure relief opening, this pressure relief opening is two and is symmetricly set on silencing and damping pipe, the length of silencing and damping pipe and the mating reaction of noise reduction cavity in air suction silencer of the present invention, during suction valve chip is opened, the interior pressure surge of gas of silencing and damping pipe and the breakdown action of suction valve chip coordinate more excellent, thereby suck more refrigerant, promoted freezer compressor gettering efficiency.By increasing, the displacement of silencing and damping rostrum is put and the sectional area of cavity in addition, has increased the long-pending ratio of this section area and pipe section, thereby has effectively increased the loss value that transmits sound from suction valve chip, has reduced noise.
3, the present invention passes through to calculate the acoustic mode state of this cavity in the frequency multiplication at compressor operation frequency (100,150,200) Hz place, thereby has reached the object of resonant silencing, has reduced the noise figure of harmonic wave.Meanwhile, by acoustic pressure, more refrigerant is compressed into cylinder, additionally increase efficiency.
4, the present invention is simple in structure, and design science is reasonable, can effectively reduce the negative pressure in muffler cavity, reduces compressor overall noise, improves the stability of compressor.

Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of freezer compressor air suction silencer that improves gettering efficiency, this air suction silencer comprises noise reduction cavity 3, silencing and damping pipe, suction port 1 and air outlet 2, silencing and damping pipe is arranged in noise reduction cavity, silencing and damping pipe is arranged in noise reduction cavity by fixing frame 11 furtherly, in its this noise reduction cavity, shock resistance demarcation strip 6 is set, this shock resistance demarcation strip is divided into one-level silencing and damping chamber 4 and secondary silencing and damping chamber 13 by noise reduction cavity, the volume ratio in this one-level silencing and damping chamber and secondary silencing and damping chamber is 1:1.6, suction port is arranged on noise reduction cavity one side lower part, suction port is broadening formation, silencing and damping tube inlet is corresponding in one-level silencing and damping chamber with suction port, the outlet of silencing and damping pipe is connected with air outlet, silencing and damping pipe is provided with pressure relief opening 9 in secondary silencing and damping chamber, pressure relief opening is two and is symmetricly set on silencing and damping pipe, silencing and damping pipe comprises the inlet duct 15 being linked in sequence successively furtherly, the first reduction of speed bend pipe 14, the second straight tube 12, the 3rd reduction of speed bend pipe 10, the 4th reduction of speed bend pipe 8, the 5th straight tube 7 and outer pipe 5, between the 3rd reduction of speed bend pipe and the 4th reduction of speed bend pipe, be provided with pressure relief opening.
Working principle of the present invention: when freezer compressor is air-breathing, because leave space between the silencing and damping pipe in suction port and noise reduction cavity, the a part of gas entering from suction port enters one-level silencing and damping chamber, another part gas directly sucks and in silencing and damping pipe, carries out reduction of speed damping, and enters secondary silencing and damping chamber at pressure relief opening part gas.Gas in silencing and damping pipe is inhaled in cylinder by the variation of compresser cylinder inside and outside differential pressure.Pulse pneumatic, by repeatedly expand decompression in baffler, has reduced noise.By the breakdown action with suction valve chip is more excellent, coordinate, thereby suck more refrigerant, promoted gettering efficiency.
