MZ1200型(xing)便携式阀门(men)研磨机(ji)具有操作简单，可以在管(guan)道(dao)现场(chang)修复阀门(men)密封面等特点。适用于研磨大型(xing)闸阀阀座、闸阀阀芯等。

MZ1200型便携式阀(fa)门研磨机结构(gou)组成

MZ1200型便携式阀门研磨机操作说明

a) 阀门研磨机各部件按顺序装好。

b) 确认研磨盘在阀座(zuo)表面的中心，如(ru)有误(wu)差可调整左右(you)摆动调整螺母进行调节。

c) 旋动前后摆动调整头使(shi)研磨片与(yu)被(bei)研磨面(mian)轻微接触。

d) 启动(dong)(dong)电(dian)机使研磨头在无(wu)任(ren)何阻力下开始低速(su)转(zhuan)动(dong)(dong)，一般(ban)磨小阀(fa)门的(de)转(zhuan)速(su)调整稍(shao)高些(xie)。磨较(jiao)大的(de)阀(fa)门时转(zhuan)速(su)调整稍(shao)低些(xie)。

e) 前后摆动(dong)(dong)调整头应连续(xu)进给，不应使研(yan)(yan)磨(mo)盘和被研(yan)(yan)磨(mo)面松动(dong)(dong)。

f) 研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)阀体(ti)时，调(diao)(diao)整摆(bai)动调(diao)(diao)整头(tou)(tou)使研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)盘离(li)(li)开被(bei)(bei)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)面(mian)(mian)，将机体(ti)连(lian)(lian)同(tong)机架一同(tong)取出，检(jian)查(cha)(cha)被(bei)(bei)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)面(mian)(mian)的情况更(geng)换(huan)(huan)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)砂纸，检(jian)查(cha)(cha)或更(geng)换(huan)(huan)完(wan)砂纸后机体(ti)连(lian)(lian)同(tong)机架一同(tong)固定在阀门上。调(diao)(diao)整摆(bai)动调(diao)(diao)整头(tou)(tou)压住被(bei)(bei)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)面(mian)(mian)继续研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)。研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)阀芯时，调(diao)(diao)整摆(bai)动调(diao)(diao)整头(tou)(tou)使研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)盘离(li)(li)开研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)面(mian)(mian)，检(jian)查(cha)(cha)更(geng)换(huan)(huan)砂纸，检(jian)查(cha)(cha)或更(geng)换(huan)(huan)砂纸后，只(zhi)需(xu)调(diao)(diao)整摆(bai)动调(diao)(diao)整头(tou)(tou)压住被(bei)(bei)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)面(mian)(mian)即可继续研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)。

g) 本(ben)机使用后(hou)应认真进行清洁，并取下研磨砂纸。

h) 电机座内变速(su)齿(chi)(chi)轮(lun)必须(xu)定期清洁干净并(bing)涂上润滑脂（二硫化钼）或(huo)类似的(de)材(cai)料(liao)，不能使(shi)齿(chi)(chi)轮(lun)暴露(lu)，以(yi)免(mian)进(jin)入杂物损坏齿(chi)(chi)轮(lun)。
