刮(gua)板(ban)(ban)(ban)機中部槽(cao)(cao)是(shi)刮(gua)板(ban)(ban)(ban)輸(shu)送(song)(song)機的機身,由中板(ban)(ban)(ban)和槽(cao)(cao)幫(bang)剛等組成,上槽(cao)(cao)運煤下(xia)槽(cao)(cao)供刮(gua)板(ban)(ban)(ban)鏈返(fan)程用(yong)。傳(chuan)統刮(gua)板(ban)(ban)(ban)機中部槽(cao)(cao)的中板(ban)(ban)(ban)對接(jie)后表面的平(ping)面度有較大誤差(cha),增大了(le)刮(gua)板(ban)(ban)(ban)運行阻力,加(jia)速(su)了(le)中板(ban)(ban)(ban)的非正常(chang)磨損。我(wo)單位生產(chan)的刮(gua)板(ban)(ban)(ban)輸(shu)送(song)(song)機耐磨中部槽(cao)(cao)和普通型的相(xiang)比,其使用(yong)壽(shou)命平(ping)均延長(chang)了(le)2-3倍,大幅度減少了(le)返(fan)修工(gong)作量,顯著提(ti)高了(le)煤礦經濟效益(yi)。
刮(gua)(gua)板(ban)機中(zhong)部槽(cao)(cao)是刮(gua)(gua)板(ban)輸(shu)送(song)機的(de)(de)機身,由中(zhong)板(ban)和槽(cao)(cao)幫剛等組成,上槽(cao)(cao)運(yun)(yun)煤下槽(cao)(cao)供刮(gua)(gua)板(ban)鏈返程用。傳統(tong)刮(gua)(gua)板(ban)機中(zhong)部槽(cao)(cao)的(de)(de)中(zhong)板(ban)對接后表面的(de)(de)平面度有較大誤(wu)差(cha),增(zeng)大了(le)刮(gua)(gua)板(ban)運(yun)(yun)行(xing)阻力,加速了(le)中(zhong)板(ban)的(de)(de)非正常磨損。我單位生產的(de)(de)刮(gua)(gua)板(ban)輸(shu)送(song)機耐(nai)磨中(zhong)部槽(cao)(cao)和普通型的(de)(de)相比(bi),其(qi)使用壽命平均延長(chang)了(le)2-3倍,大幅(fu)度減(jian)少(shao)了(le)(le)返修工作量,顯著(zhu)提高了(le)(le)煤礦經(jing)濟(ji)效益(yi)。
1. 抗沖(chong)擊力高于(yu)中板 16Mn 鋼板,不開裂,不剝落。
2. 平均硬(ying)度為 HRC60-70 ,為中板的三(san)倍以上。
3. 摩(mo)擦(ca)系數比中板降低(di) 50% 。
4. 耐酸耐堿耐鹽(yan)水腐蝕性是(shi) 16Mn 鋼板的10 倍以(yi)上。
5. 按照刮板運行方式經計算合(he)理布局,使運行阻力和(he)噪音降(jiang)至很低。
