3、射芯机热盒射芯机适于制造各种形状复杂的砂芯,随着铸造新工艺的发展,射芯机应用日益广泛,射芯机每射一次砂要排气一次,这时瞬时排气产生很强的噪声。射芯机排气噪声在产生的机制上与气吊噪声相似,但由于射芯机的射芯压力很高,如ZZ8640型射芯机的压力可达50公斤/毫米~2,ZZ8625型射芯机的压力达45公斤/毫米~2,所以排气产生的噪声更强,如ZZ8625型射芯机在距排气口0.5米处测量,
3, Core shooter Hot box core shooter is suitable for manufacturing all kinds of complex sand cores. With the development of new casting technology, the application of core shooting machine is becoming more and more widespread. Instantaneous exhaust produces strong noise. Core jet exhaust noise generated in the mechanism and the air suspension noise similar, but because of the shooting core shooter pressure is high, such as ZZ8640 core shooting machine pressure up to 50 kg / mm ~ 2, ZZ8625-type shooting core Machine pressure up to 45 kg / mm ~ 2, so the noise generated by the exhaust stronger, such as ZZ8625 core shooting machine 0.5 meters away from the exhaust port measurements,
