[Depth] China New Energy Vehicle Charging Facilities Market Research Report
 At this stage, the field of charging equipment has become a red sea, the business model is mature, but the profit margin is limited, the competition is fierce, there is homogenization phenomenon, and it will enter the stage of industrial integration; while the charging operation field is blue ocean, the business model is immature, and it is in a loss state. However, the future is vast and it is urgent to explore new business models. Swimming Pool Solenoid Dosing Pump

*Swimming pool water treatment: dosing chlorine dioxide
*Industries: e.g. paper industries, plastic industries, tissue industries: dosing additives
*Potable water treatment: dosing disinfectants
*Several types: manual control or automatic control, the automatic control can divided to: 4-20mA electric current signal control, digital impulse signal feedback control, digital impulse feedback control with Rs485 communication interface, 4-20mA electric current signal control with Rs485 communication interface.
*High speed operation: high measurement precisions, up to 360 strokes
per minute which eliminate the pulsation
effect.
*Compact size: small, quiet and stable
operation
*Durable diaphragm: the diaphragm is made by PTFE, which is
compatible with all kinds of chemicals. In typical use, the diaphragm
can last up to five years, which 5 times as national standard
GB/T7782-2008
*Strong stability: working stability in AC 100-240V, and
suitable for the range of
50-60Hz

it allowed pump to provide safe services at severe operaton
condition
*Ball check valves: it through double valve ball, seat and
sleeve to form the sealing system, that enhance the
precision
*Percentage adjustment: local adjust percentage for stroke
and frequency
0~100%
*Level monitor, low-level shutoff with alarm output
