Study abroad introduced for gear pump

Gear pumps for domestic and foreign research focuses on the following aspects:
( 1 ) Gear pump structure parameters and the optimal design of the basic design parameters of the gear pump determines the flow characteristics of the pump and the engaging performance index .truck seal Application optimization design method design parameters can be selected to meet the design requirements of gear parameters.
( 2 ) trapped oil shocks and unloading measure the phenomenon of trapped oil gear pump gear pump for the hydraulic system as a whole have had a lot of harm . Trapped oil shock and gear size and overlap factor unloading it completely and so have a great relationship ( including unloading slot position , shape and size , etc. ) .
( 3 ) the flow rate characteristics of the gear pump gear pump because a large flow pulsation , the pressure pulsation in some of the higher hydraulic systems , gear pumps rarely used . On reducing gear pump flow pulsation are already many ways , such as using composite gear pump ; reasonable choice of parameters gear ; using split gear.
( 4 ) new tooth profile of the gear pump technology research as computer-aided design and CNC machining technology rapid development , many of the past that is very complex surfaces in the design and manufacture of tooth profile becomes relatively easy. Thus, the emergence of various shapes tooth profile gear pump , such as linear conjugate tooth profile gear pumps , external gear type cycloid gear pump , and the outer envelope of the arc of the wedge toothed internal gear pumps. Straight tooth profile conjugate internal gear pump is considered to be the best overall performance ,stainless steel cable ties simple structure , displacement pressure , wide coverage, especially under high pressure , low noise and long life make it in the growing hydraulic technology figures prominently advantage position. Is Thus, for non- involute gear pump research is showing rapid development trend.
( 5 ) the characteristics of the composite compound gear pump gear pump gear pump can significantly reduce flow pulsation , but also has large displacement , small size , high mechanical efficiency , meshing force balance each other , etc. are taken seriously.
