Cement tube machine technical ways and methods for prevention and control of industrial noise
Cement tube machine technical ways and methods for prevention and control of industrial noise Cement tube machine's noise coming from the air dynamic noise and mechanical noise and three kinds of electric magnetic noise, mechanical noise is the most in the base, also is the most serious. With the development of noise control study, people mastered the various methods of prevention and control of noise, here, according to the characteristics of the cement pipe forming and the equipment to try a few comments/technical ways and methods for prevention and control of noise. A technical way, 1. Cement tube machine equipment is large and heavy, so to minimize the equipment components caused by the machining accuracy is not high and the impact and friction of noise is very necessary, and the correct calibration of equipment center, keep the dynamic mass balance is also indispensable. 2. Low noise process. Our country at present, a large number of the external vibration, the centrifugal or composite process, vibration and vibration pressure and vibration table attached type vibrator vibration and centrifuge, the centrifugal compacted cement products, such as the noise emitted by these devices forming is very big, if use internal dense - mandrel and roller suspension vibration type cement tube machine molding, pressure grouting technique can effectively reduce the noise. 3. The plasticizer and the application of high efficiency water reducing agent. In the concrete mixed with high efficiency water reducing agent and plasticizer, can improve the mobility of the concrete workability, avoid to choose strong means of dense, and compacted molding can shorten the time and the noise can play a role. Second, the technical method of noise control is a comprehensive technical measures, because the direct control from the source, it is hard to get ideal technical and economic effect. Now often USES vibration isolation and damping, sound absorption and sound insulation methods, such as for comprehensive control of noise. 1. The damping method. Using damping materials on the metal plate on the surface of the coating on the bottom of the sound body, in order to increase the interior of the sound energy loss, so as to achieve the radiation dose and the duration and reduce the noise. This law outside the vibration table, cement pipe mould vibration on the application, the effect is very good. 2. The method of vibration isolation. This method is on the basis of noise source unit vibration isolation treatment, the vibration from passed to other structures and ground. 3. The absorption method. By means of sound absorbing material to absorb the noise sound energy, sound waves of multiple reflections to abate noise. Sound-absorbing material is good for high frequency sound absorption effect. Good sound absorption material is glass wool, mineral wool, etc., more than 4 cm in thickness, high frequency sound absorption coefficient is 0.85 ~ 0.9; Intermediate absorption material such as industrial felt, asbestos, gas porous brick and etc, sound absorption coefficient is above 0.6. 4. The acoustic method. Will sound source from the production, life and other areas, such as sound insulation cover (room), sound insulation, etc., between which handled well also can effectively reduce the noise, but the large investment, long construction period, operation inconvenience. 5. Noise elimination method. It is to eliminate the air dynamic noise method. Such as boiler, air compressor and other emissions from air after noise elimination, loss of power flow and noise reduction. The above news is compiled zheng, hope to have some help to you!
