摘要： A cyclonic separation device and a vacuum cleaner including the cyclonic separation device are disclosed. The cyclonic separation device includes a housing and a cyclonic separation device. The cyclonic separation device is provided in the housing to allow dirt in a dust-containing airflow to be separated. The cyclonic separation device includes a first-stage cyclone separator and second-stage cyclone separators located downstream of the first-stage cyclone separator in a flow direction of the airflow. The second-stage cyclone separators surround the first-stage cyclone separator. The first-stage cyclone separator includes an air guide channel and a first-stage cyclone channel surrounding a part of the air guide channel. The dust-containing airflow enters, from the air guide channel, the first-stage cyclone channel for cyclonic separation and then enters the second-stage cyclone separators again through the air guide channel.

摘要： A cyclonic separator (10) comprises a separation chamber (14), a feed inlet (16) leading into the separation chamber and an underflow discharge (18) leading from the separation chamber. The cyclonic separator further comprises a vortex finder which has an inlet end positioned in the separation chamber, an outlet end defining an overflow discharge, and a bleed opening (48) defined by the inlet and outlet ends of the vortex finder and through which a portion of an overflow stream can be bled from the vortex finder to remove oversized particles from the overflow stream.

摘要： A particle separator (1) for fluids has an outlet chamber (3) arranged within an inlet chamber (2) and is fluidically connected to same, wherein the inlet chamber (2) has a curved guide surface (5) extending around a main axis (4) running transverse to the main flow direction in the inlet chamber (2) for the fluid flowing into the inlet chamber (2) via an inlet channel (6). Particles can be filtered out of the fluid largely independently of the orientation of the particle separator relative to the gravitational vector and without entering the outlet channel even after separation of the fluid flow and possible positional change. The outlet chamber (3) is closed with respect to the inlet chamber (2) transverse to the direction of the main axis (4) and open in the direction of the main axis (4), and has an outlet channel (7) that extends through the inlet chamber (2).

摘要： A vacuum installation comprises a vacuum chamber having an inlet for aspirating a quantity of liquid or particulate material. A cyclone separation unit comprising a plurality of cyclones, communicating in parallel with the interior of the vacuum chamber is connected to a vacuum pump to draw air from the vacuum chamber through the cyclones and induce a separating vortex flow within the cyclones. A controller is arranged to control the vacuum pump to provide a chosen flow rate and to selectively deactivate one or more of the cyclones according to the chosen flow rate.
