6results about How to "Increased pressure loss" patented technology

This invention discloses a variable flow pulsating flow pressure balancing system, belonging to the field of gas flow technology. It includes a pressure-stabilized gas source, characterized by: a gas flow meter and a synchronization valve installed on a first gas flow pipe, a first pressure tap on the first gas flow pipe, and a second pressure tap on a second gas flow pipe. One end of the main pipeline is connected to the pressure-stabilized gas source, and the other end of the main pipeline is connected to the inlet of a variable flow pulsating flow pressure balancer. The outlet of the variable flow pulsating flow pressure balancer is connected to both the first and second pressure taps. A first pressure transmitter is installed on the first pressure tap, and a second pressure transmitter is installed on the second pressure tap. A throttling valve is installed on the second gas flow pipe, located at the second pressure tap. When used in variable flow or pulsating flow scenarios, this invention can effectively reduce pressure fluctuations, ensure that the gas flow state in the pipeline remains stable within a very short time, and improve measurement accuracy.

The present invention provides a turbine exhaust chamber housing that forms a turbine exhaust chamber into which a hot medium flows through the moving blades of the final stage of the turbine, and forms a plurality of exhaust chamber outlets for discharging the hot medium from the turbine exhaust chamber toward the outer side of the turbine in a radial direction toward the turbine.

This application relates to an engine, powertrain, and vehicle. The engine includes: a main body; a turbocharger disposed on the exhaust side of the main body; an intake manifold disposed on the intake side of the main body; and an intercooler, partly disposed on the intake side of the main body and partly disposed on the cylinder head side of the main body. Both the turbocharger and the intake manifold are disposed close to the cylinder head side of the main body. The intercooler is fluidly connected between the intake manifold and the turbocharger. The beneficial effect of this application is that by rationally arranging the main body, turbocharger, intercooler, and intake manifold in the engine, pressure loss caused by excessively long air passages is mitigated.

The invention relates to a fluid passage system (100) for a partition of a turbine engine of an aircraft, comprising a plate (110) configured to be attached to the partition, characterized in that: - the plate (110) comprises a plurality of fluid passage channels, the channels being joined together at least two by two; - the peripheral wall of each channel extends on both sides of the plate to form a first duct (130) and a second duct (140); and - the plate (110) forms a single integral part with the first and second ducts (130, 140).
