Abstract:
Thew ater hydraulic interna l gear pump w ith ant-i leaking and ant-iw ear and ant icorrosive ab ilities is studied. Thema thematic models o f the interna l leakage flow and the optimum c learance betw een themov ing-pair parts are established. The force o f the seal compensat ionmechan ism is analyzed. The structura l opt imum design and thema in parts design are accomplished. The frict ion-pa ir materia ls o f the SF composite and the 9C r18 stainless steel and the LC9 a lum inum-alloy are used. The surface techn iques o f the p lasm a immersion, implantation for sta in less steel and the m icro arc ox idation for the alum inum-a lloy are app lied. The gear-pa ir and the sea l compensation and the shaft and the journal bearing are manufactured. The test of the pump indicates that the 75% of the vo-l ume efficiency and the 71% o f the overall effic iency are achieved w ith the tap w ater under 3. 2MPa at 32mL / r and 1 500 r /m in. The results prov ide a useful theory basis and techno logy reference.
