Through the rational planning of the structure of the low-speed centrifuge, the hygienic dead angle can be effectively eliminated. The transition of the structural parts is smooth, and the surface is polished. External structural components, fasteners, and rollers are made of stainless steel. The clamshell is a clamshell that allows for thorough cleaning of the interlayer space of the centrifuge housing without the need for a bowl. It can be started with an inverter, which is stable and stable, and the separation factor is adjustable; non-touch energy braking system; Anti-static belt drive; fuselage closed structure; The seals are made of silicone rubber or fluoroelastomer. It can meet the requirements of airtight explosion-proof, and is suitable for toxic, flammable and explosive occasions.
A high-speed centrifuge is a machine that uses centrifugal force to separate components from liquid and solid particles or mixtures of liquids and liquids. Centrifuges are primarily used to separate solid particles and liquids from suspensions; or separating two non-solutions with different densities in the emulsion (e.g., separating cream from milk); It can also be used to remove liquids from wet solids, such as drying wet clothes in a washing machine; The special overspeed tube separator also separates gas mixtures with different densities; Some sedimentation centrifuges can also classify solid particles according to their density or particle size, using different densities or different particle sizes to settle at different rates in liquids.

The difference between overload and overcurrent of the inverter
(1) The maintenance objectives are different
Overcurrent is mainly used to maintain the inverter, whereas overload is mainly used to maintain the motor. Because the capacity of the inverter sometimes needs to be increased by one or even two gears than the capacity of the motor, in this case, the inverter is not necessarily overcurrent when the motor is overloaded.
