MAIN LINE PRESSURE [13 records]

Record 1 2018-09-14

English

Subject field(s)
  • Rail Transport Operations
  • Railroad Safety
CONT

While setting off the cars at Maxville, the conductor closed the angle cocks on the adjoining ends of the cars to be separated and did not vent the air, leaving the air brake line charged on the 74 cars left unattended on the main line. This practice is known in the industry as "bottling the air. "During a train service brake application, the head-end air brake pipe pressure is reduced below the tail-end air brake pipe pressure, creating a pressure differential. When the angle cock on a car is closed before the air pressure equalizes in the brake pipe, a pressure wave is created. This wave can initiate a brake release on the car, which will then cause the brakes to release on subsequent cars.

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.
