Description
Technical field
The utility model relates to a kind of measuring pump control device, particularly a kind of fullly drawn yarn (FDY) measuring pump control device.
Background technology
The thick dawn of fullly drawn yarn (FDY) has about 55 positions at present, reason owing to the description thickness, the waste silk that each shovel board is produced is more, also influence the quality of shovel board, cause broken end more, heavy denier yarn consumption gas is many, loses bigger, hot-rolling twines waste silk easily and reduces the repiece success rate during coiling repiece, and suction gun is not easy to operate, for improving coiling repiece success rate, reduces the generation of waste silk, in the repiece process, implement the frequency conversion operation usually, promptly when repiece, reduce fullly drawn yarn (FDY) measuring pump machine operation frequency, slow down wire vent speed, increase the ease for operation of repiece success rate and suction gun, after finishing etc. repiece work, the fullly drawn yarn (FDY) measuring pump machine operation that raises again frequency ordinary production.But frequency converter is usually located in the control room, is not in the production scene, and when needs changed the frequency converter operating frequency, the staff must be positioned at the control room frequency converter is operated.And frequency converter hand-manipulated, the frequency change fluctuation is wayward greatly, and staff's variation of the on-the-spot wire vent of perception in person again, frequency conversion operation often are difficult to satisfy the requirement of producing, and influence product quality.
Summary of the invention
The purpose of this utility model be provide a kind of for the deficiency that solves above-mentioned technology and can operate at the scene, fullly drawn yarn (FDY) measuring pump control device that frequency change is stable.
In order to achieve the above object, the fullly drawn yarn (FDY) measuring pump control device that the utility model is designed, it mainly comprises measuring pump, frequency converter, contactor, breaker, electrothermal relay, measuring pump motor terminals pass through contactor, electrothermal relay links to each other with inverter output terminal, the frequency converter input links to each other with power bus by breaker, frequency converter is the frequency converter that the two-speed output function is arranged, the two-speed control signal input of frequency converter links to each other with master control electrical apparatus, master control electrical apparatus can be the rotary switch that contains at least two pairs of normally opened contacts, rotary switch can be positioned on the control box of working site, the two-speed control signal input of frequency converter, indicator lamp links to each other with the normally opened contact of rotary switch respectively, can operate frequency converter by knob at the scene, it is operated at high frequency or low frequency state, because frequency converter is two kinds of duties only, frequency change is stable, and can directly show its duty by the indicator lamp that is positioned on the control box.
The resulting fullly drawn yarn (FDY) measuring pump of the utility model control device, equipment investment is few, alleviates intensity of workers; FREQUENCY CONTROL is carried out high low speed second gear in process of production, frequency change is stable, the control of wire vent speed accurately, when the low speed wire vent, spinning worker's shovel board success rate has improved greatly, thereby reduces the number of times of broken end, suction gun is controlled easily during coiling worker repiece, increase the repiece success rate, shortened the repiece time, thereby reached the order that reduces waste silk, energy savings; And the indicator lamp that is positioned on the control box can be known the duty that shows frequency converter, thereby avoids the generation of operate miss, has eliminated hidden danger of quality, improves work quality.
