A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside of a cavity. In some cases these vanes can have variable length andor be tensioned to maintain contact with the walls as the pump r...
Experimental and numerical investigations have been carried out to study the behaviour of a centrifugal pump operating in direct mode or turbine mode. First of all, the complete characteristics head, power, and efficiency were measured experimentally using a specific test loop. The numerical data obtained from a CFD study performed with the ANSYS CFX software and based on steady state and ...
2012-3-14In the surface-mounted magnet arrangement Fig. 3a, using modern rare-earth materials with magnetic relative permeability close to unity, the effective air gap is equal to the sum of the physical airgap between rotor and stator plus the magnet depth.

2003-6-29We have experienced a noise problem with the motor that drives a vertical turbine can pump.After disassembling the motor it appeared that the rotor was touchingscratching the stator.Some opinions say that its because of the improper sized thrust bearing,but no clear cause is finalized.
2015-2-5Upping the rotor magnetic field strength, again by increasing the number of turns, or increasing the field current, as Delco did with some european models by going from a 3amp to 7amp field, also give greater output to a lesser extent, as does reducing the rotorstator air gap obvious production limitations.
2006-6-2Motor Pump. The information you had is not related to the rotor. As above, 9 leads are the quantitity of terminal wires 18 AWGfrom the stator winding. this allows for dual voltage wye connection eg 230460 Volts. The last data slotgrade of steel 30329 is very starnge, not a comon nameplate data. Who is the motor manufacturer.
The rotor-stator unit can be lifted out after opening the inspection cover on the pump housing without any special tools. The pump offers continuous, pressure-stable, low-pulsation conveyance of almost any process fluid without being affected by fluctuations in pressure and viscosity.
Progressive cavity pump,is a pump that transfers fluid through a sequence of small, fixed shape cavities as an helix shaped rotor is rotated. The rotor is formed as a single helix shape of some length. The stator or cylinder is formed as a double-helix having twice 2X the pitch of the rotor.
2016-6-10On the -1B 787, since its electric start its a simple matter to reduce the starter torque to keep the motoring speed down, but on the -2B 747-8 the pneumatic starter air valve is either openclosed, so to keep the motoring speed down they reschedule the stator vanes during the bowed rotor motoring to keep the N2 speed down.
A progressing cavity pump is a kind of rotary positive displacement pump. The main components are a rotating part, known as the rotor, and a stationary part, called the stator. The rotor is a kind of round thread screw with extremely high pitch, large thread depth and small core diameter.
The magnitude of the friction torque depends on the interference fit of the rotor and stator, the type of rotor coating and stator elastomer, the lubricating properties of the fluid, and the pump length. Because friction torque reduces the mechanical efficiency of a PC pump, use of rotorstator pairs with excessive values should be avoided.

2016-6-21In the post flight conference everybody was still confused by it until an old test pilot noted something similar was seen on the B-47 and it was due to a fuel pump issue. Fortunately for Boeing, they had certified two different manufacturers fuel pumps, otherwise the 737-300 would have had a delivery delay of several months.
