Abstract
A measuring pump stroke control is disclosed by the utility model, which consists of an electric control mechanism and a servomechanism connected with the electric control mechanism. An input port and an output port are provided on the electric control mechanism. The servomechanism controlled by the electric control mechanism is provided on a stroke screw rod of the measuring pump, and thereby can control flow of the measuring pump according to position of the instruction control stroke screw rod of the electric control mechanism through the input port and input parameters, and display flow value through the output port. In addition, flow value is displayed through the output port, accordingly, labor intensity of workers is effectively reduced, and is usable with high accuracy of regulation.
Description
Technical field
The utility model relates to a kind of Metering Pump Stroke Control Control Device.
Background technique
At present, the adjustment of metering pump stroke all adopts manual roulette wheel to regulate the pump head plunger screw rod of metering pump, thereby reach the purpose of regulating the metering pump duty, as Fig. 1, shown in 2, in adjustment process, the operator can only operate the manual roulette wheel 1 pump head plunger screw rod 2 of metering pump ' regulate ' on one side, pointer display panel 3 by seeing on one side ', not only labor intensity of operating personnel is big to adopt this method, and the adjusting of metering pump flow is inaccurate, show not directly perceived because the numerical value that shows on the pointer display panel just measures throw of pump percentage, rather than the actual liquid flow value.
The model utility content
At the deficiencies in the prior art, the purpose of this utility model be to provide a kind of effective reduction labor intensity of operating personnel, easy to use, degree of regulation is high and can realize the Metering Pump Stroke Control Control Device of telemonitoring and control.
For achieving the above object, technical solution of the present utility model is:
A kind of Metering Pump Stroke Control Control Device reaches the servomechanism that is connected with this electrical control mechanism by electrical control mechanism and forms, and described electrical control mechanism is provided with input port and output port.
Further, described electrical control mechanism is a single-chip microcomputer.
Further, described servomechanism is formed by being connected in position transducer, motor on the described electrical control mechanism and the speed changer that is connected with the output shaft of this motor, and the input end of described position transducer is located on the stroke screw rod of metering pump.
Further, described position transducer is an angular displacement sensor.
Further, described electrical control mechanism is provided with communication interface.
After adopting said structure, because the stroke screw rod of metering pump is provided with the servomechanism by electrical control mechanism control, therefore by the input port input parameter, servomechanism can be according to the position of the command control stroke screw rod of electrical control mechanism, reach the purpose of control metering pump flow, and by output port demonstration flow value, effectively reduce working strength of workers, easy to use, degree of regulation is high, and, therefore also can further realize telemonitoring and telecontrol because electrical control mechanism is provided with communication interface.
