Description
Technical field
The present invention relates to a kind of foam proportioning unit.Rotated more particularly to one kind by the fire-fighting water-driven hydraulic turbine,
The operating of foam impeller pump is driven, the fire water rotated after foam solution is pressurizeed with the driving hydraulic turbine is mixed to form fire-fighting foams liquid
Rotor machinery is pumped into formula foam proportioning unit.
Background technology
Foam proportioning unit, it is indispensable device in fire fighting device.Foam proportioning unit is main at present
There is following four generations product：
First generation product：The foam solution proportion mixer of negative pressure form.Produced during fire water passing ratio blender negative
Pressure, foam solution suction is mixed to form foam mixing liquid with fire water, is structure letter the advantages of this foam proportioning unit
It is single, low cost.Foam can also add, and shortcoming is that foams mix ratio is not precise and stable enough.
Second generation product：Pressure type foam proportioning unit, foam solution are stored in the capsule of pressure vessel, a part
Fire water extrudes foam solution into foam solution pressure vessel, and passing ratio blender is mixed to form foam solution with fire water.This
The advantages of kind foam proportioning unit is that foams mix ratio is more stable than first generation product.Shortcoming is that foam solution can not add,
Concentrated tank is pressure vessel.
Third generation product：Pressure balance type foam proportioning unit.Foam solution is stored in non-pressure vessel, and foam solution leads to
Cross pump and be pressed and delivered to equilibrated valve, equilibrated valve is by balancing foam hydraulic coupling and fire fighting hydraulic pressure, it is ensured that can pass through
Equilibrated valve enters the foam hydraulic coupling of proportioner and fire water pressure difference substantially constant, any excess foam liquid are back to foam
Flow container.This foam solution proportion mixer advantage is that foam solution can add at any time, and foams mix ratio is more stable.Lack
Point is that structure is more complicated than the second generation, and volume is big, and foam pump needs diesel engine, motor or hydraulic turbine driving, consumes certain energy.
Proportioner brings certain fire water pressure drop, simultaneously as equipment is more, fault rate is higher than the second generation.
Forth generation product：Machinery, which is pumped into formula foam proportioning unit, includes the extraordinary hydraulic turbine, foam pump and shaft coupling three
Part forms.
With the advantages that mechanism is compact, system capacity utilization rate is high, and reliability is high, and foam solution can add at any time.System
During work, mechanical energy is rotated by the hydraulic turbine output on fire water pipeline, foam pump, foam pump are driven by shaft coupling
By in the foam pressurization injection fire fighting supply pipeline in normal pressure foam tank, mixed with fire water.Suitable turbine parameter is set,
Correct foam pump is selected, foams mix keeps constant than can.Hydraulic turbine output speed and the fire water by the hydraulic turbine
Flow is directly proportional, and the output flow of foam pump is directly proportional to the rotating speed of foam pump, because hydraulic turbine main shaft and foam pump main shaft are same
Step rotation, also ensure that the ratio between the flow of foam solution and the flow of fire water keep constant.
At present, the machinery for having two kinds of forms is pumped into formula fixed froth installation:
1. the vane type hydraulic turbine is connected with foam foam gear pump by shaft coupling, the vane type hydraulic turbine and foam gear pump peace
On a common base；
Vane type hydraulic turbine major defect is due to that fire water does not have lubricity, it is easy to scratch blade, causes the hydraulic turbine
It is stuck.Require that fire water is clean simultaneously, it is impossible to there are solid foreign materials.
Because the machinery of this kind of form is pumped into formula foam proportioning unit, the vane type hydraulic turbine is placed on one with foam pump
On individual public prying body, connected by shaft coupling and transmit moment of torsion.Volume is larger.
2. the double-screw type hydraulic turbine is connected with foam three screw pump by shaft coupling, the double-screw type hydraulic turbine and the spiral shell of foam three
Bar pump is arranged on a common base.
At present, the double-screw type hydraulic turbine, driven screw rotation, when the hydraulic turbine works, active spiral shell are driven using active spiral
Rotation drives driven spiral rotating, does not have synchromesh gear to transmit moment of torsion between active spiral and driven spiral, active spiral with it is driven
Abrasion can be produced between spiral, meanwhile, active spiral, between driven spiral and the hydraulic turbine housing and have a contact, spiral with
Also abrasion can be produced between housing, so, it is desirable to fire water is clean, it is impossible to has solid particle, otherwise spiral water turbine can be ground
Damage is even stuck.
Because the machinery of this kind of form is pumped into formula foam proportioning unit, screw type water turbine is placed on one with foam pump
On individual public prying body, connected by shaft coupling and transmit moment of torsion, volume is larger.
