Abstract
The utility model discloses an energy conservation flow control device, which comprises an electric motor connected with a transfer pump, an automatic control mechanism connected with the electric motor. The automatic control mechanism comprises a sensor, a controller and a pressure switch which are sequentially connected. The pressure switch is connected with the electric motor. When a drawbench is in working position, the automatic control mechanism sets a pressure value in advance. The sensor receives the pressure of the transfer pump and feeds back signals to the controller by a signal output interface. The signals are processed by the controller. When pressure signals sent out by the controller reaches a rated vale, the pressure switch closes and is communicated with the electric motor. The electric motor regulates rotating speed by the size of the pressure, thus controlling the fluid-flow of the transfer pump and achieving the power output by the transfer pump in line with actual production requirements.
Description
Technical field
The utility model relates to the flow control device that is used to control fluid flow, particularly a kind of energy-saving type flow control device.
Background technique
At present, mechanization is produced popularizes and improves, and the flow monitoring and the control of industrial machinery cooling, lubrication system has been become an important problem.Drawbench on the enameled cable field is used for the drawbench component are lubricated the wire drawing liquid of processing, its flow drives infusion pump by speed-adjustable motor with peak output, and this power is fixing output.Lack monitoring and control gear between speed-adjustable motor and the infusion pump at fluid flow, drawbench according to different structure and model, sometimes need big flow, but do not satisfy requirement because of being in end, sometimes need small flow, therefore but cause waste, can't be according to different needs and the flow of regulated fluid also can't record actual amount.In actual applications, the power of exporting because of motor is fixed value, causes the loss of electric power bigger, has increased the manufacture cost of enameled cable, and has influenced the working life of drawbench.
Summary of the invention
The utility model purpose is to overcome original technical deficiency part, and the energy-saving type flow control device of a kind of easy to operate, accurate regulated fluid flow and environmental protection and energy saving is provided.
Goal of the invention of the present utility model is achieved in that a kind of energy-saving type flow control device, comprise the motor that is connected with infusion pump, it is characterized in that: described flow control device also comprises the automatic control mechanism that is connected with motor, this automatic control mechanism comprises sensor, controller and the pressure switch that connects in turn, and pressure switch is connected with motor.
Described sensor is located on the infusion pump, and sensor is connected with signal input interface on the controller by signal output interface.
Described sensor is a pressure transducer.
Described controller is the PID controller.
The utility model improves the flow control device of prior art, sets up automatic control mechanism, and this automatic control mechanism comprises sensor, controller and pressure switch, and sensor is located on the infusion pump.When drawbench is in running order, automatic control mechanism preestablishes force value, sensor receives the pressure of infusion pump, feed back signal on the controller by signal output interface, signal is handled by controller, when the pressure signal that sends when controller reaches rating value, pressure switch closed and with the motor conducting, motor is by the size adjustment rotating speed of pressure, thereby the fluid flow of control infusion pump reaches the required power of the infusion pump output realistic production of operation.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
With reference to the accompanying drawings shown in 1, energy-saving type flow control device of the present utility model, the motor 2 that is connected with infusion pump 1, this motor 2 is a speed-adjustable motor.Flow control device also comprises automatic control mechanism, and this automatic control mechanism comprises sensor, controller 3 and the pressure switch 4 that connects in turn, and pressure switch 4 is connected with motor 2.Wherein sensor is a pressure transducer, and this sensor is located on the infusion pump 1, and sensor is connected with signal input interface on the controller 3 by signal output interface, the pressure feedback of the required pumping fluid flow of infusion pump 1 in controller 3; Controller 3 is the PID controller, and this PID controller is made up of ratio unit and differentiation element.It is to regulate the pressure signal of sensor feedback by ratio unit proportional gain of regulating and the differentiation element that suppresses overshoot; Pressure switch 4 is a pressure control device, comprises elastic element and switching element, when by the measuring pressure overrate, the free end of elastic element produces displacement, directly or after relatively promote switching element, change the on off operating mode of switching element, reach control by the purpose of measuring pressure.Thereby the fluid flow of control infusion pump 1 reaches the required power of the infusion pump 1 output realistic production of operation.
