It is unnecessary fuzzy.Aircraft of the invention is described combined with specific embodiments below flies the method that attached mounting base expands nozzle opening,
Mounting base class of the method for the invention mainly for measuring flow, casing class product, are unsatisfactory for figure in data on flows
When paper requires, flow value can be improved by this expanding method, and guarantee oil circuit direction zero deflection.Be mainly used in fly it is attached
Mounting base nozzle opening expands operation, and the position degree of spray orifice, circularity, prevent the drill bit that fractures after raising second reaming.
Referring to attached drawing 2, the specific steps are as follows:
Step 1: calculating the aperture value after reaming；
Flow value=flow velocity × area of nozzle, wherein flow velocity is related with pressure, temperature and lubricating oil viscosity, test when this
Three kinds of parameters are fixed values, therefore flow should be directly proportional to the aperture area of spray orifice, can pass through flow rate calculation aperture.
