Frequency Conversion and Energy Saving Control System of Emulsion Pump Station
System introduction
The rated emulsion pressure of the commonly used emulsion pumping station equipment usually exceeds the actual emulsion pressure, and because the process requires the change of emulsion in operation, at present, the adjustment of pressure and flow rate by using baffle or pressure relief valve is more common, although the method is simple, it is actually achieved by artificially increasing the resistance. And with the development of technology, the invention of frequency conversion speed regulation technology has made the system of emulsion pumping station have practical application of energy saving and efficiency, and has received good results. The frequency conversion energy saving control system of emulsion pump station designed and developed by our company is designed for emulsion pump station system, and has achieved very good application effect.
System function
Safe pressure relief to ensure the safety of operators.
The suction, return liquid filtration timing automatic backwash.
Can achieve pump shaft temperature, oil level, oil pressure, motor shaft temperature, winding temperature protection.
The remote, short-range and network control can be realized, It can meet the requirement of master - control integrated computer.with the RS485 interface.
Automatic liquid distribution and rehydration function: the device can automatically carry out concentration ratio and rehydration of emulsion in emulsion tank of emulsion pumping station.
The automatic liquid preparation system: the automatic proportioning concentration of the emulsion can be detected on-line,1-5% can be continuously adjustable and set, and the precision is 0.2%. Automatic control of high and low oil level and liquid level.
Automatic detection and control emulsion pump operation function: the device can monitor and control the operation and stop the operation of emulsion pump on line and in real time.
The setting and display function of the working parameter: the control box adopts a Chinese character display man-machine interface, not only can set various working parameters at any time, but also can display the working state of the system in real time.
Protection function:leakage protection, overload, overheating, short circuit, three-phase unbalance balance, overvoltage, undervoltage, phase loss, grounding and other protection functions, with alarm function.
System characteristics
Improve the overall performance of the system: system fluid supply pressure stability, ease hydraulic shock; system pressure response fast.
The power saving is above 30% and the power factor is above 0.9.
The automatic control method is adopted to realize the constant pressure control, so that the operating frequency of the pressure relief valve is greatly reduced, the noise is reduced, and the working environment on the site is obviously improved.
The constant pressure control is realized by automatic control mode, so that the pressure in the hydraulic pipeline is maintained below the middle line of the average working pressure for most of the time, thus effectively reducing the working load of the hydraulic pipeline, prolonging the service life of the hose, and greatly reducing the loss of the sealing parts of the pipeline.
After adopting frequency conversion electronic control device in emulsion pumping station system, the maintenance times are reduced and the maintenance workload is reduced.
The system of the emulsion pump station is more comprehensive and reliable by adopting the frequency conversion electric control device
The automatic liquid distribution system is adopted in the emulsion pumping station system to make the operation of the system more intelligent, more accurate and more simple and convenient.
