Subject field(s)
  • Fire-Fighting and Rescue Equipment
  • Extinguishing Agents
DEF

A type of foam concentrate proportioning system in which a pump and appropriate devices feed the concentrate to a metering orifice or controller at the same pressure as that of the water supply.

CONT

Balanced pressure proportioner: The use of a separate pump for transporting and pressurizing foam concentrate to be delivered in the correct proportions to a flowing water stream offers the greatest advantage for reliable and accurate operation of a foam concentrate proportioning system which must function at varying rates of volume or pressure during its use. ... The balanced pressure system ... relies on: (1) a hydraulically monitored pressure control valve in a bypass foam concentrate line from a pump, and (2) a correctly sized venturi-type proportioning controller in the water line for correct and automatic proportioning over wide ranges of flow.

CONT

Balanced-pressure proportioners and around-the-pump proportioners are both systems that are built into the apparatus fire pump. Apparatus equipped with a balanced-pressure proportioner have a foam concentration line connected to each discharge outlets. This line is supplied by a foam concentrate pump separate from the main fire pump. The foam concentrate pumps draws the concentrate from a fixed tank on the apparatus. This pump is designed to supply foam concentrate to a desired outlet at the same pressure at which the fire pump is supplyng water to that discharge.

Record 6 2005-08-16

English

Subject field(s)
  • Fueling Systems (Motor Vehicles)
CONT

Fuel in the D4D is pressurised to an extremely high 135mpa within the "common rail" that feeds all four cylinders (older diesel engines have a separate pipe leading from the pump to each cylinder). The high pressure injection creates better fuel atomisation for complete burning and increased power output. And because there is less fuel wasted through inefficient combustion, the D4D delivers better fuel economy too.

OBS

A common rail engine is designed to supply constant fuel pressure to electronically controlled injectors through a shared fuel reservoir. This means that the fuel supply is not dependent on the engine revs. A common rail system is built around four basic components : a high pressure pump with pressure regulator and inlet metering valve, a rail which contains a pressurised reserve of fuel, injectors which inject precise amounts of fuel into the combustion chamber as required and a Diesel Control Unit-the ’brain’ of the system, which precisely controls injector flow and timing as well as rail pressure while continuously monitoring the operating conditions of the engine.

French

Domaine(s)
  • Alimentation (Véhicules automobiles)
DEF

Rampe d'alimentation commune, maintenue à très haute pression, qui permet une injection directe du carburant dans chaque cylindre du moteur.

OBS

Le secret de la «rampe commune», c'est son tube interposé entre la pompe d'injection et les injecteurs. Alors que dans un système d'injection directe classique, la pression dépend du régime-moteur, cette rampe commune, d'un volume de quelques centimètres cubes, va jouer le rôle de réserve de pression. Ainsi, quel que soit le régime-moteur, le moteur dispose d'une pression pouvant atteindre 1500 bars.

English

Subject field(s)
  • Pumps
CONT

Metering pumps move precise volumes of liquid in a specified time period to provide accurate flow rates. This class of pumps moves liquids in two stages : the suction stroke and the discharge stroke. During the suction stroke, liquid is pulled into the pump cavity past the inlet check valve. During the discharge stroke, the inlet valve closes; the outlet valve opens, and the liquid is pushed out. Vary the flow either by changing the stroke length or by adjusting the cycle frequency. Described below are a few types of metering pumps [i. e. ] bellows pumps,... diaphragm pumps,... piston pumps,... travelling cylinder pumps...

CONT

The Akzo Nobel water-phase preparation unit includes four holding tanks for the water-phase chemicals and dosage and mixing equipment for emulsifier, acid, stabiliser and water. All equipment is mounted on a steel structure with a pipe system that allows the use of the dosage pumps for dosing as well as for circulation, and for filling the tanks.

Record 8 2003-02-12

English

Subject field(s)
  • Diesel Motors
  • Fueling Systems (Motor Vehicles)
DEF

An injector which is camshaft-driven and incorporates a plunger. The plunger works in conjunction with orifices in the injection body to determine the beginning and end of injection. The plunger has a helix and is rotated by a rack so the beginning and end of injection can occur closer together or farther apart, thus shortening or lengthening the injection period and changing metering. A special pump which supplies fuel through an orifice to the injector operates at a pressure which is precisely controlled depending on the changes in engine speed.

Subject field(s)
  • Scientific Research Equipment
  • Printed Circuits and Microelectronics
CONT

The typical particle counter for metering the amount of particulate matter in clean work station air is an optical assembly. Air is drawn into and through the optical subassembly of the particle counter until a pre-set volume of air has been seen. The particles which are drawn into this optical subassembly cause a pulse of light to be scattered for each particle present. The light pulse is sensed by a detector which converts the pulse to an electrical voltage signal. Each signal is cumulatively counted, for the pre-set volume of air. From the amplitude of the voltage, the size of each particle can be determined. All particle counters consist of three basic subassemblies. These are the optical subassembly which "sees" the particles, a pump subassembly which draws the air stream into and through the optical subassembly, and an electronic subassembly for converting each particle size/unit number to an electrical signal. Also available, usually as an option, is some form of printer.
