5. 连续工作时间：≥200h
6. 重 量：2kg
7. 外形尺寸：120×120×180mm
三. HL-1恒流泵使用方法：
1. 初次使用时，先把“调速”旋钮调到中速位置，然后接通电源，此时指示灯亮，
滚子开始运转，调节“调速”旋钮，观察仪器运转是否正常，正常后即可使用。
2. 安装硅胶管，根据流量需要选用合适内径的硅胶管，（细管装在泵头的细槽内，粗管装在泵头的粗槽内）。
3. 预测流量，选择好合适内径的硅胶管，调整泵头的调压螺丝，同时按“排气” 旋钮，使硅胶管内的空气排出，用量杯可预测需要的流量，此时只需调节“调速”旋钮可改变流量，流量确定后请把“调速”旋钮上的“锁紧开关”往下锁紧。
4. 使用 “顺逆”开关，可以改变输液方向，使加液改变为抽液，加压改变为抽压。
5. 调节板两侧的调节螺丝是用于调节液体压力的，般只要拧到有液体流动即可，调节时须注意不要拧的太紧，否则滚子会轧死。
6. “排气”按钮的作用是在慢速时不改变原来设定流量的情况下快速排除管内空气或清洗管道。
7. 此机与BS系列收集器连用时，将四芯插头插入收集器后面板的“恒流泵”插座中，其电源受收集器控制。此机单独使用时，将四芯插头改为芯电源插头即可，本机附有备件。
四. HL-1恒流泵注意事项：
1. 调节“调速”旋钮时，请不要在“锁紧”开关锁定情况下强行调节，以免损坏旋钮。
2. 仪器在使用期间，应随时注意硅胶管是否完好，般在中速情况下运转为佳，当发现硅胶管使用老化时，应及时更换硅胶管。当仪器开始运转时，硅胶管可能有向端拱起现象，可用手拉直即可。
3. 要注意保持泵头槽内清洁，尤其对滚子轴套（中间只）必须擦干净，以免滚子轧死。
4. 恒流泵长期不用时，请把硅胶管从泵头中取出，延长其使用寿命。硅胶管是易损物品，使用段时间后请及时更换。不然会造成漏液，损坏仪器！
5. 根据不同介质和不同流量，请选用不同粗细的硅胶管。
6. 本仪器不宜输送有机溶剂和强酸强碱溶剂！

1. Overview:
HL-1 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.
. HL-1 constant-current constant-current pump pump main technical indicators:
1. Flows: HL-1 (single); HL-1S (PTFE pump head) 1-600ml / h
HL-2 (dual channel); HL-2S (PTFE pump head) 2 × (1-600) ml / h
2. Pressure: ≥ 3kg
3. Supply voltage: AC220V ± 10% 50HZ 10W
4. The use of the environment: Temperature 0 ~ 40 ℃ Humidity: <85%
5. Continuous working time: ≥ 200h
6. Weight: 2kg
7. Overall dimension: 120 × 120 × 180mm
III. HL-1 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 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.
IV. HL-1 constant-current pump 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!
