Fig. 2.122. Check of valvate springs

Check a spring deviation from a vertical which should not exceed 1,2 mm (fig. 2.122).

Check calibrating of springs.

Length of springs under loading:

– under load of 18-20 N length of a spring makes 34,50 mm;

– under load of 56,3-61,7 N length of a spring makes 24,50 mm;
