On some important quantities influencing proper functioning of the differential pneumatic comparator
Апстракт
Back-pressure air gauging is an effective and practical way of controlling
machine parts in large-scale production. It is a non-contact measuring
technique based on the flapper-nozzle effect. The proper functioning of a
differential pneumatic comparator depends on several geometric para–
meters as well as flow conditions inside the device. The main problems of
this controlling technique are the fouling of the measuring nozzle head and
changes in the accuracy of the comparator. This paper examines the
influence of the supply pressure, the diameter of the orifice in the
measuring branch, and the axial distance in the flapper-nozzle area on
pneumatic comparator performance. In a way, we are trying to optimize
the performance of a given pneumatic comparator with respect to the
tolerance field for which it is intended. The size, strength, and position of
the vacuum in the flapper-nozzle area depend on the supply pressure and
the axial distance between the measuring nozzle outle...t cross-section and
the workpiece surface. For a certain combination of these two parameters,
we can influence the vacuum quantities. A pneumatic sensitivity of a
comparator can be increased by increasing the supply pressure. The
greater accuracy of the back pressure air gauge, the smaller the
application range, i.e. the tolerance field that we can control with a given
device.
