丹佛斯齿轮泵、萨澳液压齿轮泵，齿轮泵是依靠泵缸与啮合齿轮间所形成的工作容积变化和移动来输送液体或使之增压的回转泵。由两个齿轮、泵体与前后盖组成两个封闭空间， 当齿轮转动时，齿轮脱开侧的空间的体积从小变大，形成真空，将液体吸入，齿轮啮合侧的空间的体积从大变小，而将液体挤入管路中去。吸入腔与排出腔是靠两个齿轮的啮合线来隔开的。齿轮泵的排出口的压力完全取决于泵出口处阻力的大小。 11035282 SNW3NN/075LN07SLNNBCBBNNNN/NNNNN 11035284 SNQ3NN/075LN11DBP1BCBBNNNN/NNNNN 11035500 SNP3NN/055LN02FAP1F6F6NNNN/NNNNN 11035453 SNW2NN/017RN06SVNNC7C3NNNN/NNNNN 11035458 SNW2NN/019RN06SVNNC7C3NNNN/NNNNN 11034742 SNW2NN/017RN06SMNNE6E5NNNN/NNNVN 11034700 SNP2EN/011RN03CAE4E6E5NNNN/VIWNN 111.20.590.00 SNP2NN/014RNA9BJP1C7C3D6DN/NNNNN 111.20.822.00-0L SNP2EN/011L601B1E2C3C3NNNN/VGRNN 111.20.C70.00 SNP2NN/8,0LN01SAP1C3C3NNNN/NNNNN 111.25.081.0A SNP3NN/055LN06AAP1BBBANNNN/NNNNN 121.20.790.00-0S SNU2GN/019LN02AAP1B7BBZZNN/NNNAN 121.20.791.00 SNM2GN/8,0RN01BAM1C3C3NNNN/NNNNN 121.20.792.00 SNM2DN/8,0BN06GAD2E5E5NNNN/NNNNN 121.20.793.00 SNM2GN/014LN01BAM1C7C7NNNN/NNNNN 121.26.026.00 SGM3YN/026RN07GBY6NNE6NNNN/XNNNN 211.20.888.00 SNW2NN/014RN05AGNNB7B5NNNN/NNNNN 211.25.260.0C SNW3NN/075RN02BLNNF7F6NNNN/NNNNN 11035058 SNW2NN/6,0LN02DONNB6B5NNNN/NNNNN 11032378 SNW3NN/090RN07SLNNEAE9NNNN/NNNNN 11035070 SNU1NN/3,8RN01BAP1F3F3NNNN/NNNNN 11035590 SNM2GN/022RN06GAM6E6E6NNNN/NNNNN 11035105 SKW2NN/025RN01BXNNC8C7NNNN/NNNNN 11035591 SNO2NN/025LN03CHNNB7B5NNNN/NNNNN 11035801 TAW4NN/106L502RDNNCDCBSDNN/NNNNN 11036041 SNO2NN/019LN03DONNC7C3NNNN/NNNNN 11036103 SHP2NN/022LN04DBP1B7B5NNNN/NNNNN 11035864 SNC2NN/017LN04AAC1NNNNNNNN/NNNNN 11035706 TAP4NN/106LN01DAP1CDCBNNNN/NNNNN 11035607 SNW3NN/048RN07GDNNA4A3NNNN/NNNNN 11037067 SNP2NN/011LNA9BJP1C7C3D6DN/NNNNN 11037166 SNP3NN/055LN03FBP1F6F6NNNN/NNNNN 11037122 SNP2EN/6,0RN06SAE6E6E5NNNN/VGPNN 11036159
