Gushchin N.S., Korotchenko A.Y., Nuraliyev N.F. Production of submersible centrifugal pump work members from austenitic nodular iron
Discussed is the technology of making cast impellers and guide vanes from flake graphite austenitic iron for submersible centrifugal pumps used in oil production. Proposed is the technology of making those castings from high-strength spheroidal graphite austenitic iron. Discussed are several methods of producing high-strength austenitic iron, established have been noticeable advantages of the MDS process. As a result of comparative studies there has been shown the prospectivity of using spheroidal graphite austenitic iron in the production of work members for submersible centrifugal pumps to enhance their operational reliability.

Vasenin V.I., Bogomyagkov A.V. Investigation of the work of the Bernoulli equation in multiple-gate runner system
It is shown that the Bernoulli equation is suitable for calculating the gating system with variable flow rate (mass), which varies for many times at the collector as flux distribution to gates. For the calculation the gating system breaks on two half-ring. The decision is the method of successive approximations given the difference the loss head in the halfring before the point fusion. By the fusion streams takes place the fall of the head in collector in comparison with heads before the fusion (haves the fall in 4 one).
Key words: Pouring basin, sprue, collector, feeder, head, resistance coefficient, expence coefficient, stream speed, consumption of liquid.
