Abstract
A cleaning system comprises a power plant, a regenerative blower having a power input shaft, a suction port, and a discharge port, an interface assembly configured for transmitting power from the power plant to the regenerative blower, a pump configured for generating pressurized water, and a heat exchanger system configured for heating the pressurized water.
Claims18
A cleaning system, comprising:
- a power plant;
- a regenerative blower having a power input shaft, a suction port, a discharge port, and an impeller coupled to the power input shaft;
- an interface assembly configured for transmitting power from the power plant to the regenerative blower;
- and
- a pump configured for generating pressurized water.
2 more elements
A cleaning system, comprising:
- a power plant having a power output shaft;
- a regenerative blower including a blower housing having a suction port and a discharge port and defining a blower chamber, the regenerative blower further including an impeller disposed within the blower chamber and a power input shaft extending from the impeller, wherein the impeller includes a central hub and a plurality of blades extending around a circumference of the central hub, wherein each of the blades is curved between a first end adjacent to the central hub and a second end spaced from the central hub;
- an interface assembly configured for transmitting power from the power output shaft of the power plant to the power input shaft of the regenerative blower;
- a pump configured for generating pressurized water;
- and
- one or more wands having an input configured to receive the pressurized water for distribution to a surface to be cleaned.
3 more elements
A vacuum extraction cleaning system, comprising:
- a power plant;
- a regenerative blower including:
- a blower housing having a suction port and a discharge port and defining a blower chamber;
- one or more impellers disposed within the blower chamber;
- a power input shaft extending from the one or more impellers;
- and
- one or more bearings configured to allow rotation of the one or more impellers within the blower chamber;
- an interface configured to allow coupling of the power plant to the power input shaft of the regenerative blower;
- a pump configured for generating pressurized water;
- one or more wands configured to receive the pressurized water for distribution to a surface to be cleaned;
- and
- a vacuum recovery tank, the vacuum recovery tank having a first input coupled to the suction port of the regenerative blower and one or more second inputs coupled to one or more vacuum hoses extending between the recovery tank and the one or more wands.
