Data and Analysis

1. Salt content

The room temperature during the experiment was (20-30 ℃), and according to the chart, it can be calculated that the salt content of the material has reached 25%, far exceeding 15%, which meets the experimental requirements:

The above figure shows the solubility of salt at different temperatures

2. Running time

From 3:00 pm on November 23, 2021 to 10:00 am on November 29, 2021, a total of 5 days and 19 hours, meeting the experimental requirements

Conclusion and Instructions for Use

1. Conclusion

Jingjin pump can stably transport materials with a salt content greater than 15% for a long period of time when the pressure is greater than 7MPa

2. Instructions for use

(1) It is recommended to turn on the plunger cleaning function when using a precision pump to transport high salt materials, in order to avoid wear and tear of the plunger rod caused by the precipitation of salt

(2) Carry out daily maintenance of the pump: After conveying high salt content materials, set the pump flow rate to 80% of the upper limit, rinse directly with a suitable solvent for 5 minutes to replace all the materials in the flow path. After cleaning, fill it with ethanol and seal it to prevent the solution in the pump flow path from evaporating or evaporating, and salt crystals from precipitating, causing blockage of the one-way valve or damage to the high-pressure sealing ring
