Precautions for use of centrifuge

Centrifuge is a kind of common equipment used in the laboratory It mainly uses the high-speed cyclotron to separate the colloidal solution from the solid and liquid phases It is widely used in the chemical industry, petroleum industry, food production and other industries Because the laboratory centrifuge is a kind of more precise equipment, in order to give full play to the use function of the centrifuge, we should pay attention to the relevant operation items 。 So, what are the precautions for centrifuge operation? 1 Before the operation of the centrifuge, cut off the power supply and release the brake of the centrifuge You can manually rotate the drum to see if there is any brake bite Check other parts for looseness and abnormality 2 Turn on the power supply and start the vehicle in a clockwise direction (usually it takes about 40-60 seconds from the static state to normal operation) Generally, each equipment shall be operated for about 3 hours without any abnormality after arriving at the plant 3 Materials shall be placed evenly as far as possible 4 It must be operated by special personnel, and the capacity shall not exceed the fixed amount 5 It is forbidden to overspeed the machine to avoid affecting the service life of the machine 6 After the machine is started, if there is any abnormal condition, it must be stopped for inspection, and if necessary, it must be disassembled and cleaned for repair 7 The centrifuge operates at high speed, so it is not allowed to touch the body and its drum to prevent accidents 8 The mesh number of filter cloth shall be determined according to the size of solid particles of the separated materials, otherwise, the separation effect will be affected In addition, when installing the filter cloth, the filter cloth sealing ring shall be embedded in the sealing groove of the drum to prevent the material from running in 9 To ensure the normal operation of the centrifuge, please refuel and maintain the rotating parts every 6 months At the same time, check the operation and lubrication of the bearing to see if there is any wear; if there is any wear on the components of the brake device, replace them seriously; if there is any oil leakage on the bearing cover 10 Clean the machine after use and keep it clean 11 Do not separate the non anticorrosive centrifuge from the highly corrosive materials; in addition, operate in strict accordance with the equipment requirements and regulations The non explosion-proof centrifuge must not be used in flammable and explosive occasions.
