<br> Quantitative pump pipe fitting instructions: 1, y-type filter: filter liquid impurities, avoid impurities into the pump, pump cause obstruction, hazards, <br> 2. diaphragm type pressure gauge: measurable pipeline pressure detection is abnormal, < .br> 3, release pressure valve (valve): when pumped out side line congestion, liquid through a safety valve to return to the original medicine drum, not cause flashlamp pumping out side pressure continues to increase, and endanger the pump or pipeline, General .safety valve set pressure is usually smaller than the pump of the maximum working pressure or system under pressure (min) about 1 KGF / CM ². <br> 4. pulse of the buffer (air): Elimination of pulsation, the spits out side .as to open the tap, not a front for a while, the system uses water-air compression of principle, its capacity to design more pumped out large, showing its effects only. But this kind of pulse buffer, air time will gradually dissolve in .the water for a long time, and reduces the amount of air, and the results are poor, so the fixed period of time, should be open at the top of the switch, so that the air entering the room. Although more hassle, but .its cost is relatively low. <br> 5. pulse of the buffer (balloon): the use of liquid pressure balloon, elimination of pulsating, no charge, but its cost in trouble. <br> 6, back pressure valve: the role .of the general phenomenon for backsiphonage medicine drum level compared to the bottom, then when the pump stopped, the liquid flow out and will continue until the end of the stream, its prevention method for loading back pressure valve, setting pressure, pump became operational, .the pressure must be greater than the back pressure valve set pressure is through the back pressure valve dosing, and when the pump stopped, stop the medication in a outlet port out straightaway..
