Dosing pump is also called dosing device, mainly used in the water treatment industry, play a directional dosing effect, then as a dosing device, what preparation work needs to be done before dosing start? Various dosing devices on the market are basically the same, and special attention should be paid to the high pressure range of phosphate dosing should be strictly implemented in accordance with safety procedures. Follow the metering pump manufacturers to understand it!
Note: Whether the dosing pump and stirring motor are turned clockwise (the motor housing is marked with the turn sign).
1, artificial water: add salt water to the specified position of the solution tank.
2, manual dispensing: Add a variety of drugs to the box, and reach the specified concentration (can be manually determined). Y-type filter is cleaned every three months, after cleaning, there is gas in the low pressure pipeline, then the pump should be opened to vent (apply the manual way to open the pump, when the vent screw slightly loose a small amount, as long as there is water out), until the water is intermittently emitted from the vent hole, indicating that the pressure has entered the high pressure area.
3, adjust the amount of liquid discharge of the pump: a small range of adjustment, according to the calibration of the rocker on the scale 10%- 99% can be slightly rotated, - generally 30%- 90% should be selected as the value. Large range of adjustment, next to the oil hole, unscrew the small cover, with the hex slightly fine adjustment, clockwise for large, counter-clockwise for small.
