Abstract
The utility model provides a screw-typed frequency conversion compressor, comprising a base, a sound insulation cover connected with the base, a machine foundation arranged in the sound insulation cover and an oscillation damper arranged between the machine foundation and the sound insulation cover; the sound insulation cover is provided with an air outlet and an air inlet arranged at the rear part of the air outlet; the machine foundation is fixedly connected with a normal motor; the rear end surface of the normal motor is fixedly connected with a guide cover; the sound insulation cover is also provided with an axial flow fan which is aligned with the guide cover; the guide cover and the axial flow fan are arranged at the rear part of the air outlet. The utility model has the beneficial effects that: 1. the guide cover is arranged by an installation hole at the rear end of the normal motor, which is convenient and easy to be implemented with simple structure; 2. the guide cover is provided with a blowhole and a cone angle which form an effective wind guide passage at the sound insulation cover, with small wind resistance and high heat dissipation efficiency; 3. owning to the application of the normal motor, the cost increased by the configuration of a frequency conversion motor is reduced, the generalization of the motor is improved and the storage of the motors is reduced; 4. the sound insulation cover effectively reduces the noise of the unit.
Description
(1) technical field
The utility model relates to a kind of screw type frequency-changeable compressor.
(2) background technique
The screw type frequency-changeable compressor is box, foundation-free structure substantially, and its motor all requires to adopt adjustable frequency motor, and the subject matter of this configuration is: 1. adjustable frequency motor is on the high side, has increased the cost of complete machine; 2. adjustable frequency motor and common motor are not general, cause stock's increase easily.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of screw type frequency-changeable compressor, the utility model provides a kind of can effectively reduce motor temperature, reduce the unit noise, reduce the motor cost, motor dispels the heat the simple screw type frequency-changeable compressor of flow guide structure.
The technical scheme in the invention for solving the technical problem is: a kind of screw type frequency-changeable compressor, comprise base, the sound-insulating cover that is connected with described base, be provided with support in the described sound-insulating cover, be provided with vibration damper between described support and the sound-insulating cover, offer exhaust port and the intake grill that is positioned at described exhaust port rear on the described sound-insulating cover, be connected with common electric machine on the described support, be connected with air guide sleeve on the ear end face of this common electric machine, also be provided with axial-flow blower on the described sound-insulating cover, described axial-flow blower is aimed at described air guide sleeve, and described air guide sleeve and axial-flow blower all are positioned at the rear of described exhaust port.
Further, described intake grill is positioned on the ear end face of described sound-insulating cover, and described axial-flow blower is located at described intake grill place.
Further, it is conical that described air guide sleeve is, and the cone-tip surface of air guide sleeve is to described axial-flow blower.
Further, offer vent hole on the described air guide sleeve.
Further, the bottom on described chassis evenly is provided with four rubber feet.
The utility model in use, being combined in of air guide sleeve and common electric machine forms air-guiding aisle between the sound-insulating cover, the heat radiation wind that axial-flow blower produces flows in air-guiding aisle, plays the effect of heat radiation.
The beneficial effects of the utility model are: 1. utilize the mounting hole of common motor rear end, air guide sleeve are installed, and convenient and easy, simple in structure.2. vent hole and cone angle are set on the air guide sleeve, form effective air-guiding aisle in sound-insulating cover, windage is little, the radiating efficiency height.3. the use common electric machine reduces the cost that increases because of the configuration adjustable frequency motor, and has improved the versatility of motor, reduces the stock of motor.4. sound-insulating cover has reduced the unit noise effectively.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of screw type frequency-changeable compressor, comprise base 1, the sound-insulating cover 2 that is connected with described base 1, be provided with support 3 in the described sound-insulating cover 2, be provided with vibration damper 4 between described support 3 and the sound-insulating cover 1, the bottom on described chassis 1 evenly is provided with four rubber feet 5 with further realization vibration damping.Offer exhaust port 9 and the intake grill that is positioned at described exhaust port rear on the described sound-insulating cover 2, described intake grill is opened on the ear end face of described sound-insulating cover 2, be connected with common electric machine 6 on the described support 3, be connected with on the ear end face of this common electric machine 6 and be conical air guide sleeve 7, offer vent hole on the described air guide sleeve 7.Also be provided with axial-flow blower 8 on the described sound-insulating cover 2, described axial-flow blower 8 is located at described intake grill place and is aimed at described air guide sleeve 7, and the cone-tip surface of air guide sleeve 7 is to described axial-flow blower 8.Described air guide sleeve 7 and axial-flow blower 8 all are positioned at the rear of described exhaust port 9.
The utility model in use, being combined in of air guide sleeve 7 and common electric machine 6 forms air-guiding aisle between the sound-insulating cover, the heat radiation wind that axial-flow blower 8 produces flows in air-guiding aisle, plays the effect of heat radiation.Sound-insulating cover has then reduced the unit noise effectively.
