三、CPFOTM Low frequency constant pressure liquid supply system composition

1. Intelligent emulsion pumping station

2. Automatic emulsion dispensing station

3. Emulsion tank

4. Underground automatic water supply station

5. Influent backwash filter station

6. Liquid return and backwash filter station

三、Technical advantages

1. Low frequency work (special intelligent industrial motor can work safely and stably at low frequency (below 5HZ) for a long time)

2. Constant torque (the dedicated intelligent industry can still output constant torque even in low-frequency working conditions)

3. Low running current (1. Low starting current: starting current is not higher than rated current. 2. Low running current: current and output torque are proportional and linear. 3. Starting and load changes have little impact on the system.)

(1) Low-frequency dedicated intelligent industrial motor

It can work stably at a frequency of 5Hz for a long time;

It can meet the working conditions with frequent changes in load;

(2) Dedicated smart drive

Drive system Patent number: ZL201720963901X

Patented algorithm Patent number: ZL2015 2 1027323.6

(3) System data collection

Accurately collect the pressure of the emulsion system and transmit it to the driver's PID dynamic adjustment

四、Advantage

(1) Save energy more than 40%

Since the emulsion pumping station runs continuously for 24 hours, and 70%-80% of the time runs without load, there is a lot of energy-saving space.

(2) Low noise and low temperature

Using low-frequency working mode, emulsion pump noise is reduced by 50%, and temperature rise is reduced by 40%.

(3) Pump life is more than three times longer

Low-speed operation reduces mechanical wear and prolongs the life of the pump head.

(4) Extend the sealing life of the bracket

The emulsion pump works at low speed, the temperature of the emulsion is greatly reduced, and the life of the seal is greatly extended.

(5) Extend the service life of hydraulic pipe fittings and hydraulic valves

Constant pressure working mode, no pulse phenomenon in hydraulic pipeline.
