complete mobile foam bladder tank
| 1.Mobile foam tank brief introduction: |
Half fixed foam extinguishing device is a new mobile foam extinguishing equipment, also called mobile foam extinguishing equipment, its operation is simple, reliability quickly. Used to put out a, b, c class water-insoluble liquid fire.It is widely used in municipal residential areas, factories and
mines enterprises, oil depot, chemical engineering department, heat treatment workshop, gas
stations and other places, mainly made by the foam liquid storage tanks, spray gun,proportioning mixer, hose, and cart chassis, etc
| 2.Mobile foam tank working principle |
Half fixed foam extinguishing device in extinguishing the in-line mixer at both ends of the tube
tooth interface with fire hose connection, and connect the pressure water, when there is water
that no less than 0.6 MPa pressure through the nozzle of the proportioning mixer at high speeds, due to the effect of the spread of the lateral movement of the fluid particle, proportioner indoor
form vacuum (negative pressure), so the foam liquid storage tank inside the foam liquid under the action of atmospheric pressure through pipettes into the mixer, mix with pressure water, finally
reaches a certain proportion of the mixture.When the mixture flow with certain pressure to the
spray gun, because the performance of the spray gun will air suction to quantitative.Make foam
mixture foam.So as to achieve the effect of the foam fire fighting.
