Product Details
Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.
The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.
Working principle
This product has both cooling function and heating function. It is composed of refrigeration unit, heating unit, circulation system and control system.
The refrigeration part is the use of fully enclosed compressor mechanical refrigeration, air-cooled condenser, plate heat exchanger, expansion valve, pressure protector and other components to meet the cooling requirements; heating part is the use of electric heating tube to heat the circulating liquid. The refrigerant or heat medium is transported to the interlayer of the supporting equipment through the built-in circulating pump and the external circulating pipeline to indirectly cool down and heat the materials in the reactor.
During external circulation, the upper outlet pipeline of the product is connected to the lower inlet pipeline of the kettle body, and the circulating liquid returns to the lower outlet of the product through the pipeline from the upper circulation port to form a complete circulation space.
