摘要 |
<p>A side channel pump (10) has a pumping cavity (26) which includes an inlet port (78), a discharge port (80) and side channels (72,74). An impeller (54) is mounted for rotation in the pumping cavity. A reservoir (20) holds an ample supply of liquid for pump priming and pump cooling during periods of gas pumping. A bypass suction duct (24) carries liquid from the reservoir to the pumping cavity during priming, gas pumping and normal operating and a bypass return duct (22) returns some discharged liquid to the reservoir during gas pumping and normal operation. The reservoir acts as a heat sink to enable the liquid ring formed during gas pumping operation to absorb more heat and provide pump cooling.</p> |
