Abstract
The paper describes measures to reduce the level of acoustic emittion of a low-gear external gear pump. On the basis of the experiment on a bench installation, the acoustic efficiency using rotors were made from PEEK material in the design of a gear pump was evaluated when shaft speed was of 1000 ... 2500 rpm and a discharge pressure of 3 ... 12 bar. For comparison, the article presents the acoustic efficiency by the relative difference of the acoustic emittion of the pump with configuration of the «steel-steel» and «steel-PEEK» rotors. It also provides an overview of methods for reducing mechanical noise in gears, damping of modern structural polymeric materials based on polyamide, polyacetal, polyphenylenesulfide and polyetheretherketone in comparison with traditional engineering materials - steel, aluminum, gray cast iron is estimated. Recommendations for using of polymeric materials in the design of the pump are proposed.
