Introduction:
I. Introduction
Mixed PHYM series pressure foam proportioning device consists of a pressure tank, capsules, proportioner, safety valve, exhaust valve, pressure gauge, check valve and various control valves and piping components. The main cause for the mining, paper, petroleum, chemical and underground garages and other places. After the pressure of the water supplied by the pump, the foam was replaced by a certain percentage out of the pressure water mixed with foam mixture into the device, because of the capsule will be separated from the foam liquid with water, foam liquid did not run again, next time you can continue to use and mix accuracy and stability, and reliability.
The device is suitable for a large range of flow pressure, pressure loss, in a variety of high, medium and low expansion foam fire extinguishing systems have been widely used, the structure can be divided into horizontal and vertical.
Second, the principle
When water flows through the proportioner pressure, a portion of the pressure water (3% -6%) by the manifold within the foam liquid into the extruded capsule storage tank, the replacement of the same amount of foam concentrate and another portion of water (97% -97%), mixed into a foam mixture in proportion to the foam mixer generating means for generating an air bubble out the fire.
Third, the time for the fluid
Press calculates mixer for mixing a liquid time and a flow rate ratio of
T = V / Q * r T: Time wonderful representation (S)
V: reservoir capacity liter (L)
Q: flow rate of a mixture of l / s (L / S)r: the mixing ratio of 3% or 6%
Next:Pressure foam proportioning device (vertical electric)
