重庆升降机发动机磨损尺寸在前后两缸的上部,应重点测量这两缸。气缸套的磨损情况通常用量缸表测量,量缸表就是普通的内径百分表。
1、根据货梯磨损前的缸径尺寸选择合适的接杆,在接杆上拧上固定螺母,将其拧入量缸表下端,将量缸表的测杆插入气缸套上部进行测量。
According to Hangzhou freight bore size selection before abrasion suitable extension rods, screw on the connection rod retaining nut, which is screwed into the cylinder form the lower amount, the amount of the cylinder rod inserted into the cylinder sleeve section table of measurements.
2、为了保证货梯测量的准确性,需在缸套内孔壁的上、中、下三个位置进行测量。上部位置是活塞在上止点时,第一道活塞环与缸壁接触部位;中部位置是在缸套的中部;下部位置是活塞处于下止点时,下面一道油环所对应的缸壁位置。
In order to ensure the accuracy of Hangzhou freight measurement need to be measured on the cylinder liner bore wall, the next three positions. The upper position is at the top dead center, the first piston ring and cylinder wall contact area of the piston; the central location is in the middle of the cylinder liner; the lower position of the piston is at bottom dead center, following a oil ring position corresponding to the cylinder wall .
3、将重庆升降机量缸表在磨损最大部位的横断面上转动90°测量,此时表针所指数值,即为圆度误差值,将内径百分表上下移动到一定位置测量,可测得气缸的圆柱度。
Hangzhou freight volume will rotate 90 ° cylinder table wear measurements on the largest part of the cross section, then hands the value referred to, is the circularity error value, will move to a certain position up and down the inside diameter dial indicator measuring cylinder can be measured cylindrical degrees.
