ND Electric Stroke Adjuster

Remote Control Electric Stroke Adjuster: It can receive analog signal (4-20mA) from user’s control system to change the stroke length of dosing pump in real time, further, accurately modify the displacement of dosing pump. The adjuster overcomes all major defects of modifying the capacity of dosing pump by variable frequency speed control.
Manual Control Electric Stroke Adjuster: Stroke length of dosing pump can be accurately set and displayed via the operation panel of the adjuster. With error compensation function, the adjuster overcomes the error between actual displacement and its set value directly caused by the random change of stroke length of dosing pump, because traditional knob adjuster doesn’t have the self-lock function.

ND Electric Stroke Adjuster Functional Characteristics

It can receive an analog signal (4-20mA) to change the stroke length of the dosing pump in real-time, further, accurately modify the displacement of a dosing pump.
In manual mode, the stroke length of the dosing pump can be accurately set and displayed via the operation panel of the adjuster. With the error compensation function, the adjuster overcomes the error between actual displacement and its set value directly caused by the random chance of stroke length of the dosing pump because the traditional knob adjuster doesn’t have the self-lock function.
The return-to-zero operation in the functions simply and effectively calibrates the accuracy of electric stroke adjustment, making dosing more accurate.
The disassembly and installation of the dosing pump check valve may help you better know its working principle.
In the analog signal (4-20mA) control mode, dosing in direct proportion or in inverse proportion can be achieved according to the user requirements.
In the impulse signal control mode, water meters and other impulse generation elements can be directly connected and other secondary meters need not be connected.
In the computer communication control mode, the stroke length of the dosing pump can be controlled online and the change of stroke length can be monitored and adjusted online in a real-time way, and the response is quick and accurate.
Electric stroke adjustment can achieve the adjustment of stroke length of dosing pump in other different forms on the market. Modular interface design can customize a linkage to change the dosing pumps that only allow variable frequency adjustment into the dosing pumps of which stroke length can be adjusted intelligently.
