Description

FIRE FIGHTING EQUIPMENT USING FIRE PUMP

TECHNICAL FIELD The present invention relates to fire fighting equipment, and more particularly, to a fire fighting equipment including a fire pump.

There are many types of fire suppression equipment, but water fire fighting equipment is the most economical and effective method for extinguishing most general fires, except for oil fires, electric fires and other special circumstances. Water fire fighting equipment is required to supply water from a reservoir or a water supply pipe and to eject water from the spraying unit. For this purpose, a fire pump must be installed in the water fire fighting equipment. A pump is a device that applies mechanical energy obtained from a driving device such as an electric motor or an internal combustion engine to a liquid or a gas and transports the liquid or gas to a high place, a long distance, or at a high speed through a pipe. In particular, fire pumps have been developed and developed in such a way that the extinguishing agent such as water or halogen compounds can be ejected at a constant pressure from the nozzle through a fire hose of a fire engine or a fire pipe of a building.

Fire pumps mainly use centrifugal pumps such as volute pumps and turbine pumps.They are intended for use, the construction and layout of buildings, the total capacity of fire fighting equipment, and the head of the pump. The vertical height at which it can be pulled up, the flow rate and pumping pressure available at the inlet line, and the piping design.

However, although the risk of fire in a building is high, but it is rare that a fire actually occurs, a fire pump designed with such a variety of factors is not actually used or used once or twice during the service life of several decades. It is only likely to be used. No one can guarantee that a fire pump installation that is in such a long-term standby state will operate as designed in a real fire situation. In addition to the fire pump itself, a drive such as a motor that drives the fire pump cannot guarantee emergency operation unless it is operated for a long time.

To check if the fire pump equipment is actually working, you need to perform an operation test. Unlike other fire equipment such as smoke control and disaster prevention shutters, fire pumps, sprinklers, etc. are not actually used unless you introduce personnel inside the building and remove equipment. It is virtually impossible to test the operation with In the case of halogen fire extinguishing equipment for electric fire, operation tests are not often performed because extinguishing fluid is not only harmful to the human body but also extinguishing agent is very expensive. For these practical reasons, only formal checks are made during the fire checks of the authorities, and regular facility replacement should be performed instead of the operation test.

The problem to be solved by the present invention is to provide a fire fighting equipment that can ensure the emergency operation of the fire pump in the fire fighting equipment including a fire pump in the long-term standby state.

Fire fighting equipment according to an aspect of the present invention, a fire fighting equipment including a fire pump having a supply port in which the supply of the fluid is controlled by the supply valve and a discharge port in which the discharge of the fluid is controlled by the discharge valve,

Drive may be sufficient. Further, the starting of the fire pump 11 may be sufficient to last for several tens of seconds to several minutes.

The controller 15 may include a clock device and a scheduler therein to open the operation test valve 13 and start the fire pump 11 at regular intervals such as daily, weekly, or monthly. In addition, the controller 15 may open the operation test valve 13 and start the fire pump 11 whenever the manager of the field desires or according to an external instruction such as a fire receiver or a control center.

Meanwhile, the control unit 15 attaches a plurality of sensors to the fire pump 11 and the drive unit 14 to measure mechanical to electrical performance, for example, rotation, measured at the time of operation of the fire pump 11 and the drive unit 14. It is possible to determine whether the fire fighting pump 11 and the drive unit 14 operate normally on the basis of speed, pressure, voltage, current, power factor and their time change. Furthermore, the control part 15 can notify the outside whether a fire pump 11 and the drive part 14 operate normally, for example to a fire alarm receiver or a control center by wire or wirelessly.
