摘要: A method for cleaning an air duct, in particular an air duct of a rail vehicle. The need to cool at least one load connected to the air duct is determined, the need to clean the air duct is determined, and a cleaning process of the air duct is initiated if there is no or a low need to cool the at least one load connected to the air duct and if there is a need to clean the air duct. There is also described an air intake system.

摘要: A heating/ventilating/air conditioning (HVAC) air duct cleaning system with certain improvements having a system housing containing a vacuum-generating subsystem, a rotating motor with an output shaft, and a debris reservoir; a hose connection panel on the system housing positioned at an angle of approximately 45 degrees from horizontal; and a hose coupler on the hose connection panel, configured to receive a duct cleaning hose and to transfer rotational energy from the output shaft to a connection end of a rotatable cable when received into the guide portion, wherein the coupler provides coaxial alignment between the guide portion and the output shaft.

摘要: A cleaning method includes a first removal step of causing an inert gas to which a pulsation is applied to flow into an exhaust pipe after a silicon single crystal doped with an n-type dopant is produced, to peel and remove a deposit; and a second removal step of causing an atmospheric air to which no pulsation is applied to flow into the exhaust pipe through a chamber to burn a part of the deposit with the atmospheric air, the part being not removable in the first removal step, and peel and remove a burned substance of the deposit.

摘要: The object of the invention is to provide a device which can, with high efficiency, polish and clean the inner surface of a pipe, dry the wet inner surface of the pipe, and perform coating, wherein the device does not require a large pump or a large motive force, and does not require a blast hose or a suction hose. More specifically, provided is an intra-pipe turbine blast system that moves along the inside of a pipe and performs work by spraying a fluid toward the inside of the pipe, wherein: a gas injected from a fluid supply device to the upstream-side end inside the pipe imparts speed to a mixed phase fluid consisting of a liquid and solid particles which are likewise injected into the pipe; the flow speed of the mixed phase fluid is set to 3 m per second which is the critical speed at which solid particles can float without precipitating in the liquid, and as a result of such setting, there is a great effect on reducing the energy required for causing the mixed phase fluid to move; and the mixed phase fluid with such setting is injected at a high speed from a rotation nozzle of a turbine crawler which moves inside the pipe, thereby polishing the inner surface of the pipe, and following the polishing work, the turbine crawler can clean, dry and coat the inner surface of the pipe.

摘要: A build material management system for a 3D printing system is described in which a non-fused purged build material port is to output purged non-fused build material from a build material transportation system. An emptying of substantially all non-fused build material from at least a portion of the build material transportation system to the non-fused purged build material port in response to a received purge signal is controlled by processing circuitry of the build material management system.
