四、使用要求及注意事项 Operational requirement and points for attention:
１、使用前测量套管实际外径，是否符合该型套管卡瓦卡持范围。
２、使用前应检查各销轴是否转动灵活，有无卡阻现象。
３、严禁用大锤敲击手把和卡瓦背锥面，或将卡瓦从高处摔下，以免将手
把和背锥面碰坏。
４、应经常清洗，保持卡瓦表面清洁，转动部位和背锥面涂润滑脂，防止
锈蚀。
５、经常对卡瓦进行检查:
a.检查卡瓦牙固定螺栓是否松动，防止卡瓦牙落井;
b.检查卡瓦牙是否磨钝;
c.用直尺检查卡瓦体背锥磨损情况;
d.检查卡瓦连接销磨损情况。
６、卡瓦牙磨损后，应及时全部更换，切忌将新旧卡瓦牙组合使用，以免
承受集中载荷，造成卡瓦体损坏。
７、消除卡瓦圆锥面的磨砺性物质，减少卡瓦背锥面的磨损。
８、经常检查卡瓦圆锥面的磨损情况，以避免发生下沉落井事故。
９、长期不用时，应将卡瓦清洗干净，涂防锈油，放置干燥通风处。
１０、背锥磨损严重不得修复，如自己修复后影响卡瓦扣合质量，甚至酿
成质量事故，本厂概不负责。
1)It is necessary to measure the actual external diameter of the casing to see
whether it is in the holding range of the casing slips before using.
2
2)Whether the hinge pin is rotated smoothly and whether there is any blocks
or not should be checked before operation.
3)Knocking the handle and the back cone of the slips with big hammer is
strictly forbidden, and be sure do not drop the slips from higher position to avoid
any damage to the handle and cone surface.
4)The surface of the casing slips should be kept clean by daily cleaning and
the rotary part and back cone should be coated with lubrication oil against rusty.
5)Periodic inspection should be done for the casing slips:
a)Check whether the fixing bolt of the casing slip inserts are
loosed or not in order to avoid the slip inserts dropping to the well.
b)Check whether the casing slip inserts brunt or not.
c)Checking with ruler to see whether the back cone of the casing slips is worn
or not.
d)Checking the hinge pin's condition of the casing slips, to see whether it is
worn or not.
6)The casing slip inserts should be replaced entirely in time once found it is
worn out. Be careful do not use the old inserts with the new one at the same time in
order to avoid damages to the slips body due to concentrated load.
7)Remove the harden granules away from the slips cone surface to reduce the
weariness on the cone surface.
8)Often check the wear condition of the casing slips cone surface in order to
avoid dropping into the well.
9)When the casing slips are not in use for a long time, the slips should be
cleaned and coated with anti-rustic oil and placed in a dry place with good
ventilation.
10)The back cone can not be repaired for further using once it is seriously
worn out. This factory is not responsible for any accident caused by the fact that
the slips holding quality is affected by the self-repairing of the old back cone.
