Coal 450kw 5hz Constant Pressure Liquid Supply System
CPFOTM low frequency constant pressure liquid supply system
Scope of application
Green mine intelligent heart CPFOTM low frequency constant pressure liquid supply system, applied to
the coal emulsion pump station
Product system
It is composed of professional low-frequency intelligent industrial
motor, special driver and data acquisition system. The PID dynamic
adjustment of the special intelligent driver can detect the
pressure signal of the pipe network from time to time, and compare
with the pressure setting signal. The output frequency of the
intelligent driver can be adjusted to make the actual pressure of
the pipe network consistent with the set pressure, so as to achieve
the effect of constant pressure liquid supply in the system, and
the pressure fluctuation range is around 1%.

⑦Low frequency constant pressure fluid supply technology
(1)Intelligent industrial motor for low frequency
It can work stably at a frequency of 5Hz for a long time.
It can meet the condition that the load changes frequently.
(2)Dedicated intelligent driver
Driving system Patent No. :ZL201720963901X
Patent Algorithm Patent No.:ZL2015 2 1027323.6
(3)System data acquisition
Accurately collect the pressure of the emulsion system and transfer
it to the driver for dynamic PID adjustment
Core technology
(1)PID dynamic adjustment of intelligent drive
The PID dynamic adjustment of the intelligent drive makes the
actual pressure of the pipe network consistent with the set
pressure, so as to achieve the effect of constant pressure liquid
supply system, and the pressure fluctuation range is around 1%.
- Low-frequency constant torque operation
The special intelligent industrial motor can work stably under 5Hz,
and the torque output follows well when the load changes. The
current is in the rated range, and there is no current impact on
the power grid.
- Automatic switching according to load and working mode
According to the load changes automatically adjust the output
frequency, automatic control of multi-machine working mode and
stop, switch
Advantages
- Save energy by over 40%
As the emulsion pump station operates continuously for 24 hours,
with no load for 70%-80% of the time, the space for energy saving
is large.
- Low noise and low temperature
Using low frequency working mode, the noise of emulsion pump is
reduced by 50% and temperature rise by 40%.
- Pump life extended more than three times
Low-speed operation reduces mechanical wear and extends the life of
the pump head.
- Extend the seal life of the bracket
The emulsion pump works at a low speed, which greatly reduces the
temperature of the emulsion and extends the life of the seal.
(5) Prolong the life of hydraulic pipe fitting and hydraulic valve
Constant pressure working mode, so that the hydraulic pipeline no
pulse phenomenon.
