Configuration intelligence frequency conversion is dynamoelectric carry out implement, characteristic of control valve product
Dynamoelectric carry out implement, the control that control valve wants to realize high quality and high accuracy, above all response of little to controlling signal change is sensitive; Implementation trends has been answered, actuator traversal speed must become scale with control signal extent; Want to overcome systematic static difference, actuator moves to amend set-point through ability of extremely strong fine tuning action with low speed only small error. Apparent, the execution that does not have gearshift function implement be to satisfy afore-mentioned requirements hard.
Configuration intelligence frequency conversion is carried out implement it is to use digitlization frequency conversion, sheet piece machine technology, transform what have at present to carry out implement make have intelligence to change, gearshift moves, trends has been answered, adjust fixed position precision tall, stability low, life grows good, fault rate reach the characteristic with applied more extensive circumstance.
Configuration intelligence frequency conversion is carried out implement cooperate with body of all sorts of a powerful person, can make frequency conversion of of all kinds configuration intelligence dynamoelectric control valve (next weighing frequency conversion a powerful person) . A powerful person of this kind of frequency conversion is adjusting in the process, core of a powerful person its traversal speed is change, inputting signal and a powerful person when feedback signal error is bigger, faster than common and dynamoelectric control valve, adjust quickly action. But as input signal and a powerful person feedback signal deviation is reduced, speed of electric machinery of a powerful person can slow, the athletic rate of core of a powerful person also can fall subsequently. Be close to a balance to choose career of electric machinery of a powerful person more the meeting is slower. Around valve is nodded to little is opened or can be shut in the balance, have extremely powerful fine tuning effect, its are the control precision that raised valve greatly as a result.
(one) main characteristic:
1.Imitate signal is received to control speed to be able to achieve ideal adjustment result outside using
Frequency conversion a powerful person is passed inside the control of imitate speed signal that buy intelligence turns control module to be offerred to transducer, repass transducer controls servo electric machinery to move with different speed. This one speed controls have the aid of of frequency conversion a powerful person signal, can open around set value with inferior speed, the acuteness wave motion that shuts valve to be able to prevent force of conduit internal pressure effectively. If interference makes be moved when parameter and set value deviate are bigger, the risk that frequency conversion a powerful person will operate valve to overcome interference with splitting speed and can avoid hole action to cause gradually can protect conduit and valve to avoid had sufferred press and wear away.
