关于滑触线每年的检查工作：
About sliding contact line annual inspection work:
1、检查集电器电刷绷簧压力应正常，一般1.8-2.3N/Cm2。
1, check the collector brush spring pressure should be normal, average 1.8-2.3 N/Cm2.
2、经过一年的运用滑触线的导管内一般积尘都会许多，可用压缩空气吹气，或用洁净回丝擦拭。
2, after a year of using sliding contact line of intraductal general dust will be a lot of, can use compressed air to blow, or use the waste to wipe clean.
3、检查导管有否明显变形、弯曲，选用调整悬挂螺栓方位方法进行校直。如有弯曲，变形等表象可检验校直，如无法校直应立马更换，阻止在此运用。
3, check the catheter has obvious deformation, bending, selects the adjustment hanging bolt location method for alignment. Such as bending, deformation and surface inspection alignment, such as not alignment should be replaced immediately, stop the use.
4、从导管端部取下滑触线集电器，接插电刷磨损有否超越有用长度刻度线并及时更换，检查颈部磨损情况。
4, falling from the catheter end wire collector, plug brush wear ever beyond useful to change in time, the length of the calibration and check the abrasion of the neck.
5、检查滚轮磨损情况。滚轮可保证电刷在导管中上下左右方位，滚轮磨损过多，将使电刷被擦伤或发生断电表象，电刷属易耗物品，需要经常检查，及时更换。
5, check the wheel wear. Roller ensures brush up and down or so in the catheter bearing, roller wear too much, will make the brush abrasion or blackouts appearances, brush consumable items, need to check, change in time.
6、检查导管，导轨街头如有松动、锈蚀应技能更换，检查悬吊夹、固定夹是不是松动。

6, check the catheter, guide the street such as loose, rust should change skills, check the suspension clamp, clamp is loose or not.
