COMPLESSO A POMPA PER L'EROGAZIONE DI LIQUIDI A GAS |
摘要 |
A pump assembly for delivering liquids or gases include a pump and an electromotor for driving the pump, the speed and/or torque of the electromotor being made variable by a static frequency converter. The frequency converter can be miniaturized by highly-integrated circuits and other provisions for a sufficient emission of dissipation heat. The frequency converter is arranged inside or on the pump assembly, forming a structural unit with pump assembly, and the dissipation heat of the frequency converter is emitted by the fluid delivered or to be delivered by the pump assembly, the fluid acting as dissipator. |
