Abstract
An air replenishment system includes at least one air storage tank, a pump, a plurality of air fill stations, and a check valve. The at least one air storage tank has air at a storage pressure greater than or equal to 3000 psig. The pump is coupled with the at least one air storage tank. The pump is to receive the air from the at least one storage tank and output the air at a target pressure. The plurality of air fill stations is to receive the air from the pump. The check valve is to direct air from the at least one air storage tank to the plurality of air fill stations responsive to the storage pressure being greater than or equal to the target pressure.
Claims20
An air replenishment system, comprising:
- at least one air storage tank having air at a storage pressure greater than or equal to 3000 psig;
- a pump coupled with the at least one air storage tank, the pump to receive the air from the at least one storage tank and output the air at a target pressure;
- a plurality of air fill stations to receive the air from the pump;
- and
- a check valve to direct air from the at least one air storage tank to the plurality of air fill stations responsive to the storage pressure being greater than or equal to the target pressure.
An air replenishment system, comprising:
- at least one air storage tank having air at a storage pressure greater than or equal to 3000 psig;
- a pump coupled with the at least one air storage tank, the pump to receive the air from the at least one storage tank and output the air at a target pressure;
- a plurality of air fill stations to receive the air from the pump;
- and
- a pressure regulator to control a drive pressure of drive air provided to drive the pump, the drive pressure less than a nominal pressure rating of the pump.
A system, comprising:
- a plurality of first air cylinders to provide air for use in a firefighting operation;
- a plurality of second air cylinders to store air at a storage pressure;
- at least one pump to pump air from the plurality of second air cylinders to the plurality of first air cylinders;
- a check valve coupled with the plurality of first air cylinders and with the plurality of second air cylinders, the check valve to allow air in the plurality of second air cylinders to flow to the plurality of first air cylinders responsive to the storage pressure being greater than or equal to a target pressure for the air in the plurality of first air cylinders;
- and
- a pressure regulator coupled with the at least one pump to provide drive air for the at least one pump to use to pump the air from the plurality of second air cylinders to the plurality of first air cylinders, the pressure regulator having a pressure setting less than 100 psig.
