Under normal operating conditions, its power consumption is broadly divided into two parts to traditional emulsion pump：First, it is emulsification pump
" useful part " consumed when being pressurizeed for emulsion；Second, " the useless portion of emulsification pump invalid operation consumption under unloaded state
Point ".This two parts power consumption is analyzed below：
One pumping station system is set for each coal-face, 2 emulsification pumps (the using and the reserved) of often station installation.If separate unit is newborn
The rated power for changing pump is N (Kw), emulsification pump operation 7 hours per bottom class.The liquid time one is typically actually used in face timbering operation
As be 1 hour or so (being consistent substantially with practical measurement), then the emulsification pump no-load running time be 6 hours.
For being useful power consumption for the useful power consumption that emulsion pressurizes.Useful power consumption is calculated as follows per hour：
W1=k1h1N=0.85 × 1 × N=0.85N (Kwh)
In formula：W1- per the useful power consumption of bottom class, Kwh；k1- emulsification pump descends the rate of load condensate of motor at full capacity, takes 0.85；h1—
It it is 1 hour per bottom class's supporting operation with the liquid time；N-separate unit emulsification pump motor rated power, it is N (Kw).
Emulsification pump after unloading, emulsification pump still full-speed operation, emulsification pump not discharge pressure emulsion, therefore be invalid fortune
OK.In the invalid operation phase, its power consumption is mainly the wasting of motor, the mechanical friction loss of emulsification pump and emulsion by suction
Pressure loss caused by pipeline, liquid sucting valve, tapping valve, feather valve and back liquid pipeline circulate.At this moment, although emulsification pump is in
A kind of light running state, but because emulsion will overcome the spring into, tapping valve to produce resistance, emulsification during circulating
Pump is still carried and run under certain pressure, and therefore, the power that it is consumed is still larger.Through practical measurement, emulsification pump unloading operation
When, its load factor reaches motor rated power more than 60%, and its per bottom class's run time up to 6 hours, its electricity consumed
Far more than useful power consumption.Emulsification pump is lost during unloading operation per bottom class and is expressed as：
W2=k2h2N=0.6 × 6 × N=3.6N (Kwh)
In formula：W2- per the electricity of bottom class's emulsion unloading operation consumption, Kwh；K2Load under the unloading operation of-emulsification pump
Rate is 0.6；h2- per bottom class's emulsification pump unloading run time, it is 6 hours；N-separate unit emulsification pump motor rated power, it is N
(Kw)。
Per bottom class, the electricity of consumption is expressed as when separate unit emulsifies pump operation：
W=W1+W2=0.85N+3.6N=4.45N (Kwh)
In formula：W-each working face of traditional feed flow is per the electricity of bottom class's emulsification pump consumption, Kwh；W1- per bottom class's useful work
Consumption, Kwh；W2- per the electricity of bottom class's emulsion unloading operation consumption, Kwh.
If a mine has the operation simultaneously of n coal-face, per bottom class, the total electricity of consumption is full mine emulsification pump：
WAlways=n × 4.45N (Kwh)
In formula：WAlways- when using the present embodiment feed flow full mine per the total electricity of bottom class's emulsion consumption, Kwh；N-complete
Mine while operation working face number；N-separate unit emulsification pump motor rated power, it is N (Kw).
The present embodiment employs VFC to emulsification pump, realizes " constant pressure, on demand feed flow ", therefore completely eliminate emulsification
The invalid operation of pump.If approximate supplying face pressure emulsion by the feed flow in the present embodiment and traditional feed flow two ways
What is consumed has power consumption to regard equal (being consistent substantially with actual) as, then is disappeared using the full mine of ground central fluid supply mode per bottom class
The total electricity of consumption is calculated as follows：
W’Always=n × W1=n × 0.85N (Kwh)
After traditional feed flow is changed into the present embodiment feed liquid way, its power saving rate is calculated as follows：
§=(WAlways- W 'Always)÷WAlways=(n × 4.45N-n × 0.85N) ÷ n × 4.45N=81%
Analysis is calculated more than to draw, can relative to traditional feed liquid way power saving rate using the feed liquid way in the present embodiment
Up to more than 80%.
