Description
Technical field
The utility model is related to a kind of foam proportioning units.It is revolved by the fire-fighting water-driven hydraulic turbine more particularly to one kind
Turn, drive the operating of foam impeller pump, the fire water after foam solution is pressurizeed with driving hydraulic turbine rotation is mixed to form fire-fighting foams
The screw machine of liquid is pumped into formula foam proportioning unit.
Background technology
Foam proportioning unit 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.Fire water generates negative when passing through proportioner
The advantages of foam solution sucking is mixed to form foam mixing liquid by pressure with fire water, this foam proportioning unit is structure letter
It is single, low cost.Foam can also add, the disadvantage is that the inaccurate stabilization of foams mix ratio.
Second generation product:Pressure type foam proportioning unit, foam solution are stored in the capsule of pressure vessel, a part
Fire water enters foam solution pressure vessel and squeezes out foam solution, and foam solution is mixed to form by proportioner and fire water.This
The advantages of kind foam proportioning unit is that foams mix ratio is stablized than first generation product.The disadvantage 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 is logical
It crosses pump and is 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 flow back into foam
Flow container.This foam solution proportion mixer advantage is that foam solution can add at any time, and foams mix ratio is more stablized.It lacks
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, failure rate is higher than the second generation.
Forth generation product:It includes the extraordinary hydraulic turbine, foam pump and shaft coupling three that machinery, which is pumped into formula foam proportioning unit,
Part forms.
The advantages that, system capacity utilization rate height compact with mechanism, reliability is high, and foam solution can add at any time.System
When work, by the hydraulic turbine output rotation mechanical energy 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 ratio can be kept constant.The hydraulic turbine exports rotating 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, since hydraulic turbine main shaft and foam pump main shaft are same
Step rotation, also ensures that the ratio between the flow of foam solution and the flow of fire water are kept constant.
Currently, the machinery there are two types of form is pumped into formula fixed froth installation:
1. the vane type hydraulic turbine is connect 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 since fire water does not have lubricity, it is easy to scratch blade, cause the hydraulic turbine
It is stuck.It requires fire water clean simultaneously, cannot there is solid foreign materials.
Since 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 a public prying body, is connected by shaft coupling and transmit torque.Volume is larger.
2. the double-screw type hydraulic turbine is connect with foam three screw pump by shaft coupling, three spiral shell of the double-screw type hydraulic turbine and foam
Bar pump is mounted on a common base.
Currently, 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 torque between active spiral and driven spiral, active spiral with it is driven
Will produce abrasion between spiral, meanwhile, active spiral is also to have a contact between driven spiral and hydraulic turbine shell, spiral with
Also it will produce abrasion between shell, so, it is desirable that fire water is clean, cannot there is solid particle, and otherwise spiral water turbine can be ground
Damage is even stuck.
Since 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
It on a public prying body, is connected by shaft coupling and transmits torque, volume is larger.
