Disclosed is a permanent magnet direct-drive slurry pump based on gas film drag reduction, which includes a permanent magnet motor, a main shaft, an impeller, and a valve block. The permanent magnet motor includes a housing, a stator core, stator windings, a rotor core, and a permanent magnet. The rotor core and the impeller share the main shaft, and an airflow channel is provided inside the main shaft. The impeller includes a front cover plate, a back cover plate, and blades. The blades are modularly manufactured, and blade gas jet holes and hemispherical pits are provided on the pressure surface. The airflow channel in the main shaft is communicated with the blade gas-jet holes. The valve block is disposed at the tail end of the main shaft so as to control gas exhaust and prevent liquid from entering the shaft. The present invention has such advantages as a small size, high efficiency, and strong wear resistance.

The present disclosure relates to the technical field of low-temperature pumps, in particular to a permanent magnet leakage-free low-temperature pump. The permanent magnet leakage-free low-temperature pump comprises a pump body, wherein a pump impeller is arranged in the pump body, the pump impeller and a permanent magnet motor are of a coaxial structure, no coupler device is arranged between the pump impeller and the permanent magnet motor, a motor barrel is arranged in the pump body and connected with an external power source through a wiring device to work, a first flange plate is arranged at the position, located at the front end, of the outer wall of the pump body, and a second flange plate is arranged at the position, located at the rear end, of the outer wall of the pump body.

A heating element and fluid pump including that heating element. The heating element for a fluid pump comprises a substrate, preferably made of glass, in particular quartz glass, or ceramics, a thin layer of monocrystalline, polycrystalline or amorphous material provided on top of the substrate, and electrical contacts provided in contact with the thin layer, preferably made of conductive ink or an electrically-conductive paste, wherein the thin layer has a thickness equal to or smaller than 10 μm.

The present invention relates to a modularized pump. The pump has end lids 12, 13 with an inlet and an outlet for pumped fluid, and at least two pump modules 7 sandwiched between the end lids 12,13. Each pump module includes a casing 1 with an enclosed volume 20 and at least two pump stages 6. At least one coolant inlet 10 and outlet and a separate power connection 16 for connection to a VSD is included in each module. Each pump stage 6 includes an impeller 5 with a rotor 4, a stator 2 surrounding the rotor 4, provided to drive the rotor and a can 3 between the impeller 5 and the stator 2.

Disclosed are a blade-heating heat pump cover and a heat pump. The blade-heating heat pump cover comprises a cover body having a first surface in contact with liquid and a second surface opposed to the first surface. The heat pump cover further comprises a heating element having a first end on one side of the first surface, and a second end passes through the cover body and protrudes from the second surface. The second end is provided with an electrical connection section used for energizing. The first end comprises a heating section and a non-heating section, the non-heating section is on one side of the heating section away from the second end, and the non-heating section is connected to the heating section.

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.

A fuel pump arrangement including a housing and an impeller located within the housing configured for receiving cold fuel through an inlet of the housing, wherein the impeller includes a series of vanes for drawing fluid and a nose cone defining an axis, wherein the nose cone includes a channel therethrough for passing warm fuel to an exterior surface of the nose cone for mixing with the cold fuel.

Motor housings and shrouds are detailed. Inlets of the shrouds may be included on any or all portions of their peripheries (as well as on rears of shrouds if desired). Air hence need not necessarily be drawn wholly linearly into the shrouds, permitting the shrouds to abut, or at least be closely proximate, other objects without materially diminishing air flow into the shrouds. Moreover, plates within the shrouds may be positioned so as to create torturous paths through which the air must travel. Channeling air through these torturous paths helps reduce noise as the air moves to the fans.

Embodiments disclosed herein include temperature control systems. In an embodiment, a temperature control system comprises a fluid reservoir for holding a fluid, and a spray chamber fluidically coupled to the fluid reservoir. In an embodiment, a pump is between the spray chamber and the fluid reservoir, where the pump provides the fluid to the spray chamber. In an embodiment, the temperature control system further comprises a vacuum source fluidically coupled to the spray chamber, where the vacuum source controls a pressure within the spray chamber, and where the fluid reservoir is between the vacuum source and the spray chamber.

A fluid pump includes a pump element in communication with an inlet and an outlet. Rotation of the pump element generates a suction at the inlet and pressure at the outlet. The suction and pressure cooperate to move a fluid through a fluid path. An accessory fluid path is in communication with the inlet and outlet. The accessory fluid path includes a thermistor in communication with the accessory fluid path. The thermistor monitors a temperature of the fluid within the accessory fluid path.
