  • Horizontal foam tank

    Product Name: Pressure Proportional Mixing Device

    The device is composed of a foam tank, a pressure proportional mixer, a diaphragm, a water inlet pipe, a liquid outlet pipe and a control valve.

    working principle:

    When the pressure water flows through the proportional mixer, a part of the pressure water (3% -6%) enters the foam liquid storage tank through the branch pipe to squeeze the capsule, displacing the same amount of foam liquid with another part of the water (97% -94%). The foam mixed liquid mixed in the mixer is provided to the foam generating device, which generates air foam for fire extinguishing.

    Use range:

    The device can be combined with fire pump (or fire truck), foam generating and spraying equipment to form a fixed (or semi-fixed) foam fire extinguishing system. It is widely used to extinguish Class A (except liquefied gas), Class B, and Class C fires. It is safe and reliable It has the advantages of high fire-extinguishing efficiency, and is the most commonly used fire-fighting equipment in oil depots, oil refineries, chemical plants, oil fields, terminals, tankers, aircraft depots, airports, and oil boiler rooms.

    The device divides the membrane type and the ordinary type according to the filling method, and divides it into horizontal and vertical types according to the tank placement method. The foam mixing ratio is generally 3% or 6%. The mixed liquid flow of this device is 32 ----- 160L / S, and the storage tank volume is 1000-16000L with different specifications. According to the required mixture flow rate and foam spraying time, the ratio mixer and foam tank can be arbitrarily combined into a series of products to meet the needs of engineering applications.

  • Mobile fire extinguishing device

    1. Semi-fixed foam fire extinguishing device is a new type of mobile foam fire extinguishing device, also called mobile foam fire extinguishing device. Its operation is fast, simple, and reliable. It is used to extinguish class A, B, and C water-insoluble liquid fires. It is widely used in municipal residential areas, factories and mines, oil depots, chemical departments, heat treatment workshops, gas stations and other places. It is mainly composed of foam liquid storage tanks, spray guns, proportional mixers, hoses, and cart chassis.

    2. Working principle of semi-fixed foam fire extinguishing device

    The semi-fixed foam fire extinguishing device is connected to the fire hose with the pipe joints at both ends of the pipeline proportional mixer during fire extinguishing, and is connected to the pressure water source. At the nozzle of the mixer, due to the lateral movement and diffusion of the jet particles, a vacuum (negative pressure) is formed in the chamber of the proportional mixer, so the foam liquid in the foam liquid storage tank enters the mixer through the suction pipe under the effect of atmospheric pressure , Mixed with pressure water, and finally reach a certain proportion of the mixed liquid. When the mixed liquid with a certain pressure flows to the spray gun, a certain amount of air is sucked in because of the performance of the spray gun. The foam mixture was foamed. So as to achieve the effect of foam fire.

  • PCL foam generator

    Model: PCL16

    Working pressure range: 0.4 ~ 0.6Mpa

    Flow: 16L / S

    Flow coefficient: 429

    Foaming multiple: 5.0 (minimum value)

    25% liquid analysis time: 2.1min (minimum value)

    The PCL air foam generator is mainly composed of a shell, a foam nozzle and a guide plate.
    When the mixed liquid flows through the foam nozzle, a diffused atomized jet is formed, which generates a negative pressure around it, thereby sucking a large amount of air to form an air foam. Air foam nozzles and guide plates are input into the storage tank, drip down the tank wall, and cover the combustion liquid surface smoothly for fire extinguishing.
