    摘要: A cutoff for a blower housing. The cutoff comprises a cutoff having an edge, the edge includes first and second ends and a midsection. The midsection includes an acoustical reduction section. Each end includes an efficiency enhancing portion curving from a first smaller radial dimension to a second greater radial dimension proximal the acoustical reduction section. The acoustical reduction section is located between the first and second ends and has a greater third radial dimension greater than the first or second radial dimensions.

    摘要: An air handling blower housing for an HVAC system is formed by two opposed housing parts which are each fabricated of a compression molded reinforced thermoset polymer composition. The housing parts are joined along a parting line, preferably perpendicular to the axis of a motor driven impeller mounted within the housing by wedge shaped clips which engage cooperating bosses aligned with each other when the housing parts are joined. The construction of the housing parts provides for an improved method of assembly of an air handling blower of a type particularly adapted for HVAC systems.

    摘要: An airhandling unit for an HVAC system includes a cabinet having an electric motor driven centrifugal blower disposed therein. The blower includes a scroll or volute type blower housing which may be formed of opposed releasably connectable housing parts. The blower housing parts include opposed sidewalls with axially extending compound curved portions which cooperate with an end wall which is configured to have portions which are not of substantially constant increasing radial distance from the blower impeller axis of rotation. However, a constantly increasing airflow cross-sectional flow area is provided within the blower housing for blower discharge air. The disposition of the blower housing sidewalls with respect to the cabinet walls provides improved airflow distribution for air flowing into the blower air inlet openings.

    摘要: Disclosed are an axial fan assembly and a motor home air-conditioner using same. The motor home air-conditioner comprises an air-conditioner body (1). A heat exchanging system, a central air-inlet channel (2) and a peripheral air-outlet channel (3) are arranged in the air-conditioner body (1). The heat exchanging system comprises an evaporator assembly (4) distributed in a ring and an axial fan assembly (5) located within the evaporator assembly (4). The axial fan assembly (5) comprises an axial fan (6) and a skeleton-type blast ring (7). The axial fan (6) is mounted within the skeleton-type blast ring (7). The skeleton-type blast ring (7) comprises a drainage pressurized region (71) and an airflow diffusion region (72) for air to flow out. The airflow diffusion region (72) comprises a circumferential air-outlet region (721) and an axial air-outlet region (722). The present axial fan assembly not only meets the requirement of strength in installation, but also changes the direction of airflow blown by the axial fan to achieve the blowing effect of mixed windflows

    摘要: The present invention relates to a spiral pumping stage for a vacuum pump, which is particularly intended to be arranged at an additional side inlet (48) of a vacuum pump (40) and allows to obtain an improved pumping speed at said additional side inlet. According to the invention, the spiral pumping stage comprises both centripetal (11) and centrifugal (21) pumping channels, so that the gas is pumped from the periphery to the center of the pumping stage throughout a first group of pumping channels and it is pumped from the center to the periphery of the pumping stage throughout a second group of pumping channels. Thanks to this inventive arrangement, both the gas coming from a previous pumping stage or a main pump inlet (42) arranged upstream the pumping stage according to the invention and the gas coming from the additional side inlet (48) can be effectively pumped by the pumping stage according to the invention.
