| 摘要 |
<p>The invention relates to a machine (1) for fluid transportation, especially compressor or pump, comprising: a fluid displacement unit (FDU), a driving unit (DU), a common shaft (SH), which transmits torque from the driving unit (DU) to the fluid displacement unit (FDU), a common casing (CS), a suction line (SL) and a discharge line (DL), wherein the flow (PF) is divided by at least one division unit (DV) into a primary flow (Fl) to be pumped or compressed and a secondary flow (F2), which is led to internal heat sources (HS) in the casing (CS) for cooling purpose by a conduction system (CO). A throttling device (TH) is arranged in the suction line (SL) and a division unit (DV) is arranged upstream, wherein the flows (F2, Fl) are reunited downstream the throttling device (TH).</p> |
