Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 with to Fig. 6
A kind of air compressor that has sound-insulating cover, comprise air compressor 1, be covered with sound-insulating cover 2 on the air compressor 1, sound-insulating cover 2 is made of framework 21 and acoustic board 22, described frame facet and end face are provided with dismountable acoustic board 22, and acoustic board 22 is provided with the acoustical cotton (see figure 1).
The air intake filter of air compressor 1 directly is installed on the air compression machine host and does as a whole placing in the acoustic hood 2, has eliminated the suction noise (see figure 2) effectively.
The gas of the by-pass port emptying of air compressor 1 returns intakeport by recovery channel, and the integral body of forming a compact structure with the air compressor main frame places in the acoustic hood 2, has both saved the energy, has reduced bypass exhaust sound (see figure 2) again effectively.
The hot air that motor exhausting mouth 3 is discharged 4 is directly arranged to acoustic hood 2 outsides through the labyrinth by the exhaust passage again, making compression curve move down thereby the hot air of both having avoided the motor cooling to produce causes the ambient temperature in the case to raise makes the output power rising of motor increase energy consumption, avoided motor and electric control box to break down again because of overheated, simultaneously, the sound output that goes out through the motor exhausting oral instructions decays through the labyrinth, noise be effectively controlled (seeing Fig. 3 a and 3b).
At framework 21 tops, acoustic hood 2 is designed to double layer construction, and top layer is designed to inlet and outlet labyrinth 4 structures of separation mutually.The case side in the place ahead is driven gas port 41 on compressor 1 main frame, from the downward aeration in main frame top, guarantees the air supply of compressor inlet through top layer air inlet labyrinth 4; Open the suction port 41 of motor radiating cooling air in case side, motor rear, this suction port 41 connects a Sound Attenuator, has avoided the leakage of noise effectively; The gas port 42 that above motor, begins to rehearse above the case, and can match ventilating fan, the air of discharge through the exhaust labyrinth from case top exhaust.Like this, the exhaust that makes progress from the air inlet of two sides, front and back and from the middle part of the circulating air of case inside, air flows all plays the effect (see figure 4) of good natural cooling to main frame and motor.
Described sound-insulating cover 2 is provided with the flange 6 that is used for the pressurized air exhaust, and the flange 6 inner flexible pipes that adopt are connected with air compressor 1.Described sound-insulating cover 2 be provided be used for cooling circulating water into and out of flange 7, the inner flexible pipes that adopt of flange 7 are connected with air compressor 1.The employing flexible pipe is connected, and can compensate the position degree deviation that case and main frame are installed, and the outside makes things convenient for the client that (see figure 6) is installed.
Whole sound-insulating cover 2 is designed to demountable structure, four channel-section steels are formed the case underframe, " ∏ " shaped steel of moulding and angle steel connect to form the framework of case as column and crossbeam by bolt, and the crossbeam on the top adopts " ∏ " shaped steel to be inverted and slight inclination, can play the effect of rhone.All paste two inches thick acoustical cottons on the door-plate, can directly assign on the underframe, guarantee door-plate and framework installation firmly closely by door lock again by the locating stud on the case underframe.Need only open door lock during maintenance takes off door-plate and gets final product.The case underframe can link to each other with the main frame underframe by four " L " type constitutional details, thereby makes case become as a whole with compressor, makes things convenient for whole Transporting.In the compressor operating process, case and compressor must be separate, to avoid noise and vibration transfer.Case also can disperse independent shipping, can save shipment and delivery cost greatly like this.
The sound-insulating cover of a kind of centrifugal compressor described in the utility model, the design of sound-insulating cover have effectively reduced the outside transmission of noise, have reduced the noise pollution of environment, and sound-insulating cover described in the utility model is simple in structure, and be easy for installation.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
