Cooling water circulating pump product use method and use matters needing attention

2022-07-28

cooling water circulation pump is to take the form of mechanical refrigeration low temperature liquid circulation equipment, with the provision of low temperature liquid, low temperature water bath function. Combined with evaporator, vacuum freeze drying oven, circulating water vacuum pump, magnetic stirrer and other instruments, multi-functional chemical reaction operation and storage at low temperature.

cooling water circulating pump can be matched with a variety of instruments (rotary evaporator, fermentation tank, chemical reaction kettle, freeze-drying equipment, biopharmaceutical reaction kettle, etc.); The refrigerating capacity is large and the refrigerating speed is fast, which greatly improves the working efficiency. The flow rate of the circulating pump of this machine can be adjusted and customized to greatly meet the actual needs of different users. All models of this machine can be used at low temperature and refrigerating capacity according to user requirements, reasonable collocation between low temperature and container volume.

product use:

1, open the water tank cover, according to the required constant temperature requirements, pour the corresponding amount of medium (2cm below the bath side).

2. Connect the cooling circulating pump to the system used in the experiment according to the general method shown in Figure 1, and connect the liquid inlet and outlet of the equipment with the liquid outlet and inlet of the experimental instrument correspondingly with the heat preservation hose. If only the cooling circulating pump is used for cold bath operation, connect the inlet and outlet of the circulating pump.

3. Put the power plug properly into the dedicated independent socket.

4. After power on, turn on the safety switch and power switch, and the instrument displays the actual temperature.

5, turn on the refrigeration switch, and the compressor starts to work after a three-minute delay. (For both machines, the high-temperature machine works first, and the low-temperature machine works after a three-minute delay to the -30°C set by the high-temperature machine, and the refrigeration indicator light is on)

6. At the same time, if there is an internal training cycle, the internal circulation valve of the pump switch can be opened at the same time to ensure that the bath temperature can be opened (intermittent opening. Otherwise, it is necessary to start the circulating pump.

7. After the temperature reaches the set temperature, open the circulation switch and valve, cool the cooling instrument, and start the test.

. After the experiment is over, turn off the circulating pump switch, refrigeration switch, power switch, pull down the safety switch and unplug the power plug for the instruments that need to be cooled first.

9. If it is not used for a long time, please release the coolant. Rinse with clean water.
