The metering pump is a motor driven by a direct-connected transmission system to push the rack and pinion for variable-speed motion, and under the effect of the crankshaft connecting rod, the rotary motion is transformed into a reciprocating uniform linear motion. The metering pump slide rail and the valve plate are immediately connected. When the slide rail moves repeatedly during operation, the valve plate is directly pushed (pulled) to instigate back and forth. The actual effect of opening and closing the throttle valve on the top of the pump head is used for suction and discharge purposes, and it reaches the liquid transporting point. Function.
Due to the electromagnetic driven metering pump, there is only one fitness movement component - electric linear axis. Generally speaking, the lower the movable member, the stronger the sunlight metering pump works.
The metering pump is very suitable for low flow and low working pressure workplaces, and it has a better compensation effect when the power supply voltage fluctuates. Compared with a diaphragm metering pump with fixed frequency and modified stroke length, what are the advantages of a metering pump with fixed stroke length and modified frequency? Through calibration, the dose per stroke is known. Therefore, the overall dosing amount can be calculated (dosing amount = dosing amount per stroke * frequency).
The total dosage is linearly related to the frequency (50% frequency = 50% dosage). Through the external single-pulse or analog control, the dosage can be changed from Z to Z within one second. In addition, it is much lower than the maintenance cost of the stroke length of the motor drive. The metering pump is a machine that can measure and verify the transportation of liquid, also known as variable pump and proportional pump.
The general outline is: the metering pump is a kind of production process that can meet all kinds of tough requirements, and the total flow can be adjusted within the range of 0-99.9%. An especially positive displacement pump for transporting liquids (especially corrosive liquids).
