正壓稀相氣力輸送系統(tǒng)是采用羅茨風機或者羅茨空壓泵作為動力源。利用空氣動能作為輸送介質(zhì)，物料以比較高的速度并以分散懸浮的狀態(tài)在管道中輸送。輸送的壓力一般根據(jù)工況條件不同可在幾千帕到幾百千帕范圍內(nèi)調(diào)整。　　正壓氣力輸送利用氣體動壓，物料以較高速度在輸送管道中前進(8m/s-25m/s )，輸送壓力沿輸送管道逐漸降低?！　⌒读祥y/星型卸料器/旋轉(zhuǎn)閥常用在氣力輸出系統(tǒng)中。對于壓力輸出系統(tǒng)或負壓輸出系統(tǒng)，星型卸料器可以均勻、連續(xù)地向輸料管供料，以保證氣力輸出管內(nèi)的氣、固態(tài)比較穩(wěn)定，從而使氣力輸送能正常工作，同時又能將卸料器的上、下部氣壓隔斷而起到鎖氣作用。因此，星型卸料器是氣力輸送系統(tǒng)中常用的重要部件。【電話/微信咨詢：陳經(jīng)理18068546632】　　正壓風送卸料閥針對物料粘接，風力直吹轉(zhuǎn)子清理物料?！　≈饕馁|(zhì)：不銹鋼304-316、鈦合金、鋁合金、各種合金?！倦娫?微信咨詢：陳經(jīng)理18068546632】     《掃二維碼-添加 陳經(jīng)理 微信-咨詢防卡型正壓風送卸料閥》　　The positive pressure dilute phase pneumatic conveying system uses Roots blower or Roots air pump as the power source. Using air kinetic energy as a conveying medium, materials are transported in pipelines at relatively high speeds and in a dispersed and suspended state. The conveying pressure can generally be adjusted within the range of several thousand pascals to several hundred kilopascals according to different working conditions.　　Positive pressure pneumatic conveying utilizes gas dynamic pressure to move materials at a high speed (8m/s-25m/s) in the conveying pipeline, and the conveying pressure gradually decreases along the conveying pipeline.　　Unloading valves/star shaped unloaders/rotary valves are commonly used in pneumatic output systems. For pressure output systems or negative pressure output systems, the star shaped unloader can uniformly and continuously feed the conveying pipe to ensure that the gas and solid in the pneumatic output pipe are relatively stable, so that the pneumatic conveying can work normally, and at the same time, it can also block the upper and lower air pressure of the unloader and play a role in air lock. Therefore, the star shaped unloader is an important component commonly used in pneumatic conveying systems.
