刮(gua)(gua)板(ban)(ban)(ban)機(ji)(ji)(ji)(ji)中部槽是刮(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送機(ji)(ji)(ji)(ji)的機(ji)(ji)(ji)(ji)身，由中板(ban)(ban)(ban)和(he)槽幫(bang)剛(gang)等組成，上槽運(yun)煤下槽供(gong)刮(gua)(gua)板(ban)(ban)(ban)鏈(lian)返程用。傳(chuan)統(tong)刮(gua)(gua)板(ban)(ban)(ban)機(ji)(ji)(ji)(ji)中部槽的中板(ban)(ban)(ban)對接后表面的平面度有較(jiao)大誤差，增大了(le)刮(gua)(gua)板(ban)(ban)(ban)運(yun)行阻力，加(jia)速(su)了(le)中板(ban)(ban)(ban)的非正常磨損。我單位(wei)生產的刮(gua)(gua)板(ban)(ban)(ban)輸(shu)(shu)送機(ji)(ji)(ji)(ji)耐(nai)磨中部槽和(he)普通(tong)型的相比(bi)，其使(shi)用壽命平均延長了(le)2-3倍，大幅度減少了(le)返修工作量(liang)，顯(xian)著提高了(le)煤礦經濟(ji)效(xiao)益。
刮(gua)(gua)板(ban)(ban)(ban)(ban)機中部槽(cao)是刮(gua)(gua)板(ban)(ban)(ban)(ban)輸(shu)送機的(de)(de)機身，由中板(ban)(ban)(ban)(ban)和(he)槽(cao)幫剛等組成(cheng)，上(shang)槽(cao)運(yun)煤下槽(cao)供刮(gua)(gua)板(ban)(ban)(ban)(ban)鏈(lian)返程用(yong)(yong)。傳統刮(gua)(gua)板(ban)(ban)(ban)(ban)機中部槽(cao)的(de)(de)中板(ban)(ban)(ban)(ban)對(dui)接(jie)后表面的(de)(de)平(ping)面度(du)有較(jiao)大誤(wu)差(cha)，增大了(le)刮(gua)(gua)板(ban)(ban)(ban)(ban)運(yun)行阻(zu)力，加速了(le)中板(ban)(ban)(ban)(ban)的(de)(de)非正常(chang)磨損。我單位生產(chan)的(de)(de)刮(gua)(gua)板(ban)(ban)(ban)(ban)輸(shu)送機耐(nai)磨中部槽(cao)和(he)普通型(xing)的(de)(de)相(xiang)比，其使用(yong)(yong)壽命平(ping)均延(yan)長了(le)2-3倍，大幅度減少了返修(xiu)工作量，顯著提高了煤礦經濟效益。
