Description
The technical field of the invention
The present invention relates to electronic prime mover, relate in particular to and be used to open and/or the automatically controlled adjuster of control valve and damper, in order to the flow of control feed-line and ducted liquid.
Background technology related to the present invention
For industrial feed-line and ducted fluid, the automatic control equipment of its flow is extensive use of in a lot of fields, as generating, oil, oil, the purification of gasoline, paper pulp and paper, chemicals, Food ﹠ Drink, the processing of petroleum chemicals, the processing industry of water and waste water.So far, the AC asynchronous motor that constant speed is used is housed on such adjuster, this AC asynchronous motor links to each other with adjuster by a worm gear/gear on worm transmission case, and is integral with this adjuster.
A shortcoming of prior art systems is: the combination of different motor and gear box all needs to supply with the output speed of regulation, and this has caused high total amount.In addition, because the combination of each motor and gear box has a constant output speed, thus need change assembly or translative mode usually, so that realize the change of rotating speed.
Another shortcoming of prior art systems is to be a designated value in order keep output to change in wide rotation speed change scope to turn round, and needs a large amount of motor.In order to reduce cost, the quantity of motor is used in restriction in general the enforcement, and this causes changeing the increase of turning round with rotating speed and reduces.
Another shortcoming of prior art systems is: gear box makes and occurs wear surface (therefore causing friction loss) between motor and output driving shaft.
In this system, the adjuster of prior art comprises the electronics and the mechanical function element of different brackets, and they constitute this device, and regulate inside.But, these function element show some problems, comprise in order to realize that muscle power regulates, and cause lag of processing time, and the operations of inserting in the middle of all need to be used to reduce the time of the power of device, and the power that reduces device is for safety and access permission.
The lathe of most prior art is included in and carries out manually operated scheme in the supply of electric power failure procedure.In the meantime, mainly be induction and monitor these manual operations, so that holding position indication and can not lose the initial calibration scale.Some general existing adjusters are indicated for such position is provided, and complicated transmission mechanism is installed.
An object of the present invention is to provide a kind of improved automatically controlled adjuster that is used for by-pass valve control or damper, it provide a kind of in the whole range of speeds when constant commentaries on classics is turned round the rotating speed of stepless variable.
Summary of the invention
According to an aspect of the present invention, proposed a kind of automatically controlled adjuster that is used for by-pass valve control or damper, wherein, this valve or damper have a job changes the regulating shaft of turning round greater than 10Nm, and described automatically controlled adjuster comprises:
(ⅰ) support,
(ⅱ) rotating driving shaft that is installed in the support, it comprises one first end, this first end stretches out from support, and directly links to each other with the regulating shaft of valve or damper,
(ⅲ) one can produce the motor of turning round greater than the 10Nm commentaries on classics, and this motor axially is installed on the driving shaft, and
(ⅳ) device of control motor work.
In a preferred form of the present invention, the connection motor of a special use and the device of driving shaft are arranged, this driving shaft can suitably have a clutch.
Best this variable-ratio, permanent magnetism, the motor that constant commentaries on classics is turned round is that DC motor is turned round in a big commentaries on classics by pulse width modulation (PWM) control.
The permanent magnet direct current motor of this pulse width modulation control provide one can stepless change in whole minimum/maximum (top) speed scope output speed (is one-level with a RPM).Therefore one embodiment of the present of invention can comprise 6 to 12 kinds different from the alternating current motor of prior art and the adjuster that assembles of gear box.Setting by changing the pulse width modulation duty-cycle (by a keypad that is installed on this device, or a hand-held device, or from a remote position) can change the rotating speed of this motor in the scope of a regulation.Two embodiment of the present invention can substitute the combination (supplier's extent of supply) of the alternating current motor and the gear box of 24 kinds of different prior aries, and this causes low reserve level, and have not been required to be change rotating speed/commentariess on classics and turn round and make up and the change pattern is satisfied the demand.
This permanent magnet direct current motor provides one to keep constant commentaries on classics to turn round in the whole range of speeds.
Axially motor of installing and direct-connected axle have been eliminated the wear surface of the required gear box of prior art systems.Because the intrinsic friction energy loss in the prior art systems is eliminated, so the mechanical efficiency that the invention provides.Another advantage of the present invention is that location sensitive and supervision need not transmission mechanism and just can realize in the manual control process.
Motor comprises a stator and a rotor.Stator links to each other with the solid-state semiconductor conversion equipment of a three-phase, and this conversion equipment is carried direct voltage from a three-phase rectifier.By opening this solid-state device, motor is driven as an alternating current motor.Therefore this conversion equipment plays inverter.
By control the running of this solid-state conversion equipment with a pulse width modulating signal, the rotating speed of motor can infinitely change between minimum of stipulating and maximum.Electronic function is designed to the range of speeds in an appointment of the commentaries on classics place of turning round of requirement output.
A microprocessor is controlled the pulse width modulating signal of the rotating speed of this regulation, and keeps these rotating speeds with reference to rotor-position sensor, and wherein these rotating speeds are set in the work Control Parameter.
If the load that puts on the axle causes that rotating speed begins to descend, microprocessor is with the corrected impulse bandwidth modulation signals so, this will make the voltage that is transformed on the stator become big, and allow the rotating speed that requires is revised, and bigger commentaries on classics be turned round need and can be kept at the constant rotational speed place that sets.
When this motor was used as the base of an adjuster, the device of a particular design of permission produced the output commentaries on classics of regulation and turns round in the mobility scale of output speed.
Adjuster of the present invention is equipped with a motor driving controller and a manual interface microprocessor controller.This motor driving controller comprises all drivings and protects the required circuit of this motor.
This microprocessor is according to program work, so that control impuls width modulated device, motor speed just can change in its whole range of speeds like this.This microprocessor allows to set all work Control Parameter, and send a special alarm when arbitrary setting exceeds also with loader.
In one embodiment of the invention, this adjuster comprises an artificial interface controller, and this manual interface controller comprises the circuit that allows all parameters to set from the Local or Remote position.For this basic operation of adjuster, this controller connects into microprocessor, is complementary with the specification of control system, and this controller is an element on the function in control system.Field signal control also is by this circuit, manages through an interface that is complementary.
