Abstract
The invention discloses a rolling oil controlling system for controlling the flow and the pressure of rolling oil in aluminum rolling mill production. The system comprises an oil tank, a main pipeline connected on the oil tank and a PLC (Programmable Logic Controller) control system capable of controlling the whole system, wherein the other end of the main pipeline is connected with an injector head; a variable frequency pump driven by a variable frequency motor is arranged on the main pipeline at one side of the oil tank; a pressure sensor and a flow sensor are arranged on the main pipeline at one side of the injector head; detection signals sent by the pressure sensor and the flow sensor are input to the PLC control system; control systems of the PLC control system is output to the variable frequency pump; and the revolving speed is adjusted by the variable frequency pump according to the control signals. By adopting the structure, the pressure and the flow can be controlled; the power can be automatically adjusted according to the pressure and the flow; and therefore, the energy-saving production is realized.
Description
Technical field
The present invention relates to be used in the production of a kind of aluminium milling train the flow of controlled rolling oil and the rolling EFM Electronic Fuel Management of pressure.
Background technology
In the Rolling Production process; The flow of ROLLING OIL and pressure; Quality to sheet material has played crucial effect; Traditional control mode all is to send the signal of 4-20mA through pressure sensor, comes the pressure of controlled rolling oil through the pneumatic diaphragm control valve of PLC control bypass, adopts such control mode can only controlled pressure and can not the oily flow of controlled rolling.The employing pneumatic diaphragm control valve not only can be because of source of the gas and quality problems; Usually do not reach the effect of better controlling, and adopt bypass to come controlled pressure, the power of pump is in unanimity from start to finish; Can not regulate power automatically, the energy has been caused waste because of the pressure size.
Summary of the invention
The technical problem that the present invention will solve provide a kind of not only can controlled pressure and flow, and can regulate the rolling EFM Electronic Fuel Management that power carry out energy-conservation production automatically according to the size of pressure and flow.
In order to solve the problems of the technologies described above, rolling EFM Electronic Fuel Management of the present invention comprises fuel tank and is connected the main line on the fuel tank that the other end of main line is connected with injector head, and the main line that is positioned at fuel tank one side is provided with the variable frequency pump that is driven by variable-frequency motor; Be positioned at the main line that sprays first side and be provided with pressure sensor and flow sensor; Comprise that also one can be controlled system to the PLC that whole system is controlled; The detection signal that pressure sensor and flow sensor send inputs to PLC control system, and the control signal of PLC control system exports variable frequency pump to, and variable frequency pump is regulated rotating speed according to control signal.
After adopting above-mentioned structure; Owing to control the motor speed of variable frequency pump through PLC control system; Thereby reach the purpose of control flow and pressure, with the pneumatic diaphragm control valve control mode of traditional pressure sensor control bypass, the signal that makes pressure sensor and flow sensor transmission 4-20mA into is through the variable-frequency motor control of PLC to variable frequency pump; Thus not only can controlled pressure and flow, and can regulate power automatically according to the size of pressure and flow and carry out energy-conservation production.
Description of drawings
Fig. 1 is a ROLLING OIL control system schematic of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, rolling EFM Electronic Fuel Management of the present invention is done further explain.
As shown in the figure; Rolling EFM Electronic Fuel Management of the present invention; Comprise fuel tank 1 and be connected the main line 2 on the fuel tank 1; The other end of main line 2 is connected with injector head 3, and the main line 2 that is positioned at fuel tank one side is provided with the variable frequency pump 5 that is driven by variable-frequency motor, and two or more variable frequency pumps 5 that driven by variable-frequency motor of parallel connection can be set according to actual needs; Be positioned at the main line 2 that sprays first side and be provided with pressure sensor 6 and flow sensor 7; Comprise that also one can be controlled system 8 to the PLC that whole system is controlled; Pressure sensor 6 inputs to PLC control system 8 with the detection signal that flow sensor 7 sends, and the control signal of PLC control system 8 exports variable frequency pump 5 to, and variable frequency pump 5 is regulated the rotating speed of variable-frequency motor according to control signal.
Through above-mentioned setting, variable frequency pump sends the signal of telecommunication of 4-20mA through pressure sensor and flow sensor, and to PLC control system, system controls the motor speed of variable frequency pump through PLC control, thereby reaches the purpose of control flow and pressure.
Energy-conservation realization is following:
1, production technology needs, and a former rolling intact roll bending material needs to shut down, wear band, and it is rolling to carry out next time again, and pump is not out-of-work in the meantime, oepration at full load always, through L type tee ball valve to tank drainback, energy waste.Adopt the pump of variable-frequency motor now, can make when shutting down, frequency is transferred to minimum, reduces rotating speed, reaches purpose of energy saving like this.
2, work the time is not adopted the bypass decompression but frequency reduces the control rotating speed of motor, reaches purpose of energy saving.
