The Reason Why The Domestic Desktop High-speed Centrifuge Is More Popular Is Here

The desktop high-speed centrifuge is widely used in various production industries and is also widely used in various laboratory research units because of its technical advantages and physical advantages.

Of course, desktop high-speed centrifuges are also the darlings of clinical medicine, biochemistry, genetic engineering, immunology, etc., and are common equipment used by hospitals, research institutes, and institutions of higher learning for centrifugation.

According to incomplete data statistics, domestic desktop high-speed centrifuges are more popular in the industry because of the lower price and more reliable maintenance than the similar centrifuges in foreign countries. Of course, the main reason is that the installation is convenient, because after the purchase of the domestic desktop high-speed centrifuge, the installers will come together to install and teach the basic operators to work, and the imported centrifuge can rarely do this. Explain the comparison of the installation requirements of domestic and imported desktop high-speed centrifuges:

When the imported desktop high-speed centrifuge is in operation, the unit has strict airflow direction requirements, otherwise it is difficult to make the equipment reach the ideal state.

(1) The exhaust side of the discharge port for separating the mother liquid is a natural exhaust vent;

(2) For the forced air inlet, the desktop high-speed centrifuge is designed with an intermediate compartment, and the airflow discharged by the solid phase and the liquid phase is sealed by the air volume of the inlet air to serve as a sealing function. When the centrifuge is running, the chamber is negatively pressurized due to the centrifugal action, and the suction is equal to the suction, so that the solid phase and the liquid phase of the centrifuge are discharged;

(3) For the forced exhaust vent, this airflow will not be discharged, which will cause the air resistance of the silo of the desktop high-speed centrifuge, increase the running current and vibration, and cause accidents due to bridging in serious cases (the dewatering filter cake has a certain water content, flow Very bad). When considering forced exhaust, there is a margin to calculate the exhaust volume because there is extraneous gas intervention in the intermediate chamber of the imported centrifuge. When the domestic centrifuge is in the running state, the domestic centrifuge has no intermediate chamber, and the solid-liquid two-phase sealing is completed by the labyrinth seal and the soft seal.

(1) For the natural exhaust vents, the equipment manufacturer shall bring its own steam-water separation tank, and the piping at the upper end of the separation tank shall meet the exhaust requirements;

(2) For the forced exhaust port, although the domestic centrifuge does not have the intervention of external gas, in order to enable it to achieve the good operating state, forced exhaust should be considered.

China's centrifuge manufacturers pay attention to quality development, so the centrifugal machine production technology is very invested, so the domestic desktop high-speed centrifuge is also making progress, there are some medium and high-end centrifuge equipment on the market, with operation. Smooth, small size, beautiful appearance, low temperature rise, high efficiency and wide applicability.
