粗管裝在泵頭的粗槽內(nèi)）。
3. 預(yù)測(cè)流量，選擇好合適內(nèi)徑的硅膠管，調(diào)整泵頭后面的調(diào)壓螺絲，同時(shí)按“排
氣” 旋鈕，使硅膠管內(nèi)的空氣排出，然后用量杯可預(yù)測(cè)需要的流量，此時(shí)只需調(diào)節(jié)
“調(diào)速”旋鈕可改變流量，流量確定后請(qǐng)把“調(diào)速”旋鈕上的“鎖緊開關(guān)”往下鎖緊，并記錄對(duì)應(yīng)的轉(zhuǎn)速。
4. 使用 “順逆”開關(guān)，可以改變輸液方向，使加液改變?yōu)槌橐海訅焊淖優(yōu)槌閴骸?
5. 調(diào)節(jié)板兩側(cè)的調(diào)節(jié)螺絲是用于調(diào)節(jié)液體壓力的，般只要擰到有液體流動(dòng)即可，調(diào)節(jié)時(shí)須注意不要擰的太緊，否則滾子會(huì)擱死。
6. “排氣”按鈕的作用是在慢速時(shí)不改變?cè)瓉碓O(shè)定流量的情況下快速排除管內(nèi)空氣或清洗管道。
7. HL-2B數(shù)顯恒流泵與BS系列收集器連用時(shí)，將四芯插頭插入收集器后面板的“恒流泵”插座中，其電源受收集器控制。此機(jī)單獨(dú)使用時(shí)，將四芯插頭改為芯電源插頭即可，本機(jī)附有備件。

1. HL-2B digital constant-current pump Overview:
HL-2B digital constant-current pump is in the HL series of constant-current pump, based on the increase shows that the function of constant-current pump speed. Advantage of being able to directly observe the constant speed pump, through the conversion and projections to calculate the actual current flow pump to facilitate the constant-current pump control, intuitive, more accurate speed control, you increase production and experiment sample (liquid) and the sample (liquid) is the ideal instrument.
HL-2B digital 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, performance reliable and so on. 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.
. HL-2B digital constant-current pump main technical indicators:
1. Flow: (single) HL-1B; 1-600ml / h 2. Speed :0-50 r / min around
(Dual channel) HL-2B; 2 × (1-600) ml / h (digital display)
3. Supply voltage: AC220V ± 10% 50HZ 10W 4. Pressure: ≥ 3kg
5. The use of environment: temperature 0-40 ℃ Humidity: <85% 6. Continuous working time: ≥ 200h
7. Overall dimension: 120 × 120 × 180 mm 8. Weight: 2kg
III. HL-2B digital constant-current pump to use:
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 bed,
Rough pipe installed in the pump head of the rough bed).
3. Forecast traffic, the choice of a good fit of the silicone tube diameter, the pressure regulator adjustment screw behind the pump head and at the same time press the "row
Gas "knob, so that the silicone tube from the air, and then the amount of glass needed predictable flow, only regulate at this time
"Speed" knob can change the flow of traffic after determining the "speed" knob on the "lock switch" lock down, and record the corresponding speed.
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, or else will be tied up roller.
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. HL-2B constant-current pump with a few notable 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.
