一烧车间的50m~2烧结机是日伪时期的老设备,其配套使用的3200离心式风机,耗电多、效率低,严重影响烧结生产的技术经济效果。 为贯彻提高产品质量和降低能源消耗的经济发展方针,烧结总厂技术人员在参照英国毫甸式后弯型风机结构,设计了SJ3500新风机。投产后,与离心式3200风机比较,负压提高292mmH_2O,风机效率提高到
A burning workshop 50m ~ 2 sintering machine is the old equipment during the Puppet period, supporting the use of 3200 centrifugal fan, power consumption, low efficiency, seriously affecting the technical and economic effects of sintering production. In order to carry out the economic development guideline of improving product quality and reducing energy consumption, the technical personnel of Sintering Plant designed SJ3500 new blower with reference to the structure of Housed Bend Fan in UK. After put into operation, compared with the centrifugal fan 3200, negative pressure increased 292mmH_2O, fan efficiency increased to
