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.
HD2004W the constant speed electric mixer to increase the electronic constant speed circuit, when you adjust the speed button, set at a certain speed, increase the load, resulting in a decrease in speed, speed signal voltage drop, then the given signal voltage unchanged. These two signals are compared in the operational amplifier, the output signal increases, so that the motor supply voltage increases, increases the torque, the speed is basically unchanged, and the purpose of constant speed is achieved. The constant speed electric stirrer adopts a deep closed loop at constant speed, so it can work at constant power at low speed. The speed regulation adopts a touch switch, which can reverse the work if necessary for stirring. The speed setting has a memory function and a timing function.
