The present application relates to the technical field of air jet speed balancing of
spinning machines, and particularly relates to a
spinning machine air jet speed balancing method and
system based on an elliptical eccentric
air chamber, which comprises the following steps: changing the second
air chamber in the double
air chamber into an elliptical air chamber, and offsetting it to the direction of the supply
pipe by setting a centrifugal distance; calculating the gas
mass flow at the inlet of the supply
pipe, and then solving the pressure distribution of the first air chamber; mapping the
ellipse to a circular domain and calculating the gauge coefficient, and obtaining the pressure distribution of the elliptical air chamber in combination with the pressure distribution of the first air chamber; establishing a
jet flow speed calculation model of the air jet hole, and calculating the air jet speed of the
spinning machine in combination with the pressure distribution of the elliptical air chamber; and solving the optimal elliptical semi-
minor axis and centrifugal distance with the target of minimizing the air jet hole speed variance, and adjusting the shape and position of the elliptical air chamber. The present application reduces the
pressure difference at the positions of the air jet holes by the design of the
ellipse plus eccentricity, so as to balance the flow, reduce the air jet hole speed difference, and meet the production demand of high-quality spinning.
