The High Pressure Coolant Injection (HPCI) System consists of a pump or pumps that have sufficient pressure to inject coolant into the reactor vessel while it is pressurized. It is designed to monitor the level of coolant in the reactor vessel and automatically inject coolant when the level drops below a threshold.
An air pump is a pump for pushing air. Examples include a bicycle pump , pumps that are used to aerate an aquarium or a pond via an airstone ; a gas compressor used to power a pneumatic tool , air horn or pipe organ ; a bellows used to encourage a fire; a vacuum cleaner and a vacuum pump .
High Pressure Pure Air Generator (HiPPAG®) is a registered trade mark belonging to Ultra Electronics for a type of Pure Air Generating System (PAGS). [2] HiPPAG® is an integrated pure air compressor and filtration system, which continuously consumes atmospheric air during flight or on the ground, and then provides high pressure pure air to cryogenically cool the infrared detector in missile ...
Map of pressure systems across North America. A pressure system is a peak or lull in the sea level pressure distribution, a feature of synoptic-scale weather.The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg).
A hydropneumatic pulsation filter is a pressure container with separate inlet and outlet, connectable to a pipe system so that all pressure changes must attempt to pass through said chamber. Entry and exit of said chamber being of a diameter relative to chamber diameter that provides a high discharge coefficient, and without close proximity of ...
A high-integrity pressure protection system (HIPPS) is a type of safety instrumented system (SIS) designed to prevent over-pressurization of a plant, such as a chemical plant or oil refinery. The HIPPS will shut off the source of the high pressure before the design pressure of the system is exceeded, thus preventing loss of containment through ...
In science and engineering the study of high pressure examines its effects on materials and the design and construction of devices, such as a diamond anvil cell, which can create high pressure. High pressure usually means pressures of thousands (kilo bars ) or millions (megabars) of times atmospheric pressure (about 1 bar or 100,000 Pa).
Usually there are 2 systems, one to control the pressure and the other to control the flow. The inputs are usually from pressure and temperature probes from the intake and at various points through the engine. Also throttle inputs, engine speed etc. are required. These affect the high pressure fuel pump.
