peristaltic pump , constant flow pump DHL-A
1. Overview:
constant-current pump is a liquid extract of the quantitative increase in equipment, it has a transmission flow stable, continuously adjustable, non-delivery of material contact with the outside world to prevent pollution and small size, light weight, reliable performance, etc. advantages. Therefore, it is widely used in factories and mines, universities, hospitals and research institutes, and will become a production and research equipment essential one, all the needs of micro, quantitative fluid infusion or extraction can be used for occasions.
2. Usage:
1)The initial use, the first "Speed" knob to the medium-speed position, and then connect the power, when the indicator light,
Roller started to regulate the "Speed" knob, observation equipment is functioning properly, you can use normal.
2) The installation of silica gel tube, according to the need to use the appropriate flow of the silicone tube diameter, (thin tube installed in the pump head of the small shafts in the pump head tube rough rough bed).
3) Forecast traffic, the choice of a good fit of the silicone tube diameter, adjust the regulator screw pump head, at the same time press the "exhaust" knob, so that the silicone tube from the air, dosage cup predictable flow needs at this time only regulation of "Speed" knob can change the flow of traffic after determining the "speed" knob on the "lock switch" lock down.
4) The use of "good or bad times" switch, you can change the direction of fluid, so that the rate of change for pumping liquid fluid, pressure to change the pump pressure.
5) Adjustment plate on both sides of the adjustment screw for regulating the liquid pressure is generally as long as the twist of the liquid can flow, be careful not to adjust the screw too tight, otherwise the roller will be run over.
6) "Exhaust" the role of the button when in slow traffic does not change the original settings quickly ruled out the air tube or pipe cleaning.
7) This machine with the BS once a series of traps, it will be four core plug collector panel after the "current pump" in the socket, the power control by the collector. This machine used alone, it will be replaced by two four-core plug to plug, the machine with spare parts.
3. NOTES:
1) Regulation "Speed" knob, do not "lock" switch lock circumstances forced adjustment knob so as to avoid damage.
2) In the use of period instruments, should be at any time pay attention to whether silicone tube intact, the general circumstances in the medium-speed running is better, when the aging was found when the use of silica gel, silica gel tube should be replaced. When the equipment started to operate, the silicone tube may have to end arch phenomenon can be straightened by hand.
3) We should pay attention to maintaining the pump head tank cleaning, in particular roller sleeve (the middle one) must be clean so as not to run over rollers.
4) The long-term constant-current pump when not in use, please put in the silicone tube from the pump head removed, extending its life. Silicone tube is fragile items, use a period of time after the replacement in time. Not cause leakage, damage to equipment!
5) According to different media and different flow, use of different thickness of the silicone tube.
6) The equipment should not transfer the organic solvent and strong acid strong base solvent
