摘要： To obtain a vacuum pump which appropriately performs temperature management of a gas flow path and reduces restrictions on a gas flow rate attributable to the temperature management. A cooling tube performs temperature adjustment of a gas flow path. A first temperature sensor is arranged at a position closer to the gas flow path than the cooling tube, a second temperature sensor is arranged at a position closer to the cooling tube than the gas flow path, and a control apparatus controls, based on a sensor signal of the first temperature sensor and a sensor signal of the second temperature sensor, (an on-off valve of) the cooling tube so that a temperature of the gas flow path approaches a predetermined gas flow path target temperature.

摘要： A heating pump includes a driving electric motor; a pump case, wherein a pump cavity and a heating cavity are defined in the pump case, the pump cavity and the heating cavity are roughly arranged side by side in an axial direction and are in communication by means of a communication channel, and a water inlet and a water outlet are formed in the pump case; an impeller arranged in the pump cavity; and a heating member arranged in the heating cavity. Therefore, not only is the size of the heating pump favorably reduced, the impeller may also be prevented from being radiated at a temperature by the heating member, such that the premature aging of the impeller may be prevented, and thus, the usage performance of the heating pump may be improved.

摘要： A fluid pump includes a pump element where rotation of the pump element generates suction at the inlet and pressure at the outlet to move fluid through a fluid path. An inlet orifice directs a portion of the fluid through the accessory fluid path that includes a low-restriction return path providing a continuous flow of the fluid through the accessory fluid path and to an outlet orifice. A circuit board housing includes a contoured portion and a PCB with a thermistor in communication with contoured portion. The continuous flow is directed between the contoured portion and the outlet orifice between a rotor and the outer wall. The low-restriction return path maintains a temperature of the continuous flow of the fluid within the contoured portion of the accessory fluid path to be similar to a temperature of the fluid in the fluid path.
