Abstract
A pump assembly includes a pump having a fluid inlet and a fluid outlet, and an electric motor having a drive mechanism that is connected to the pump mechanism. The assembly includes an adapter plate having an inlet port, an outlet port, and at least one fluid passage between the inlet port and the outlet port. The at least one fluid passage is at least partially defined by the adapter plate. The motor is thermally coupled to the adapter plate and the fluid outlet of the pump is fluidly connected to the inlet port of the adapter plate. The pump is configured to pump fluid through the at least one fluid passage of the adapter plate, and the adapter plate is configured to discharge the fluid.
Claims20
A pump assembly comprising:
- a pump having a fluid inlet and a fluid outlet;
- a motor having a drive mechanism that is connected to the pump mechanism;
- and
- an adapter plate having an inlet port, an outlet port, and at least one fluid passage between the inlet port and the outlet port, the at least one fluid passage being at least partially defined by the adapter plate,
- wherein the motor is thermally coupled to the adapter plate and the fluid outlet of the pump is fluidly connected to the inlet port of the adapter plate, the pump being configured to pump fluid through the at least one fluid passage of the adapter plate, and the adapter plate being configured to discharge the fluid.
An open pump system comprising:
- an enclosure;
- a pump arranged within the enclosure, the pump having a pump housing with a fluid inlet and a fluid outlet, and a pump mechanism enclosed by the pump housing;
- a motor arranged and sealed within the enclosure, the electric motor having a motor housing and a drive mechanism enclosed by the motor housing, wherein the drive mechanism is connected to the pump mechanism;
- and
- an adapter plate arranged within the enclosure, the adapter plate having an inlet port, an outlet port, and at least one fluid passage between the inlet port and the outlet port, the at least one fluid passage being at least partially defined by the adapter plate, wherein the motor housing is thermally coupled to the adapter plate,
- wherein the fluid outlet of the pump is fluidly connected to the inlet port of the adapter plate, the pump being configured to intake fluid from outside the enclosure through the fluid inlet and pump the fluid through the at least one fluid passage of the adapter plate, and
- wherein the fluid is discharged out of the enclosure from the outlet port of the adapter plate.
A method for cooling a motor in a pump and motor assembly, the method comprising:
- intaking a flow of fluid through a pump inlet of a pump;
- discharging at least part of the flow of fluid through a pump outlet of the pump;
- pumping the at least part of the flow of fluid through a fluid passage defined in an adapter plate that is fluidly connected to the pump outlet, wherein the adapter plate is in thermal contact with a motor housing that contains the motor;
- and
- discharging the at least part of the flow of fluid through a discharge passage defined in the adapter plate.
