Laboratory Hospital University Easy To Use TD4 Low Speed Centrifuge

The TD4 desktop low-speed centrifuge Features:

★ The bio-safety airtight angle rotor adopts a silicon rubber integral sealing ring (EU RoHS 2015/863), which can avoid aerosol spillage and fully guarantee the safety of the staff and the laboratory environment.

★ The rear austenitic 304 stainless steel centrifugal cavity is equipped with all-steel spray-plastic shell, one-piece stamped and formed steel front face and three-layer steel protective cover and other security devices, which are both sturdy and durable, and ensure the safety of staff and laboratories. .

★ The use of silent electromechanical integrated motor door lock is easy to use. Just gently close the door cover, and the door lock system will be triggered to lock the door cover safely.

TD4 Low Speed centrifuge Common failure analysis

★ After the power is turned on, the control panel displays normally. When the start button is pressed, the centrifuge works normally. But when the stop switch is pressed, the centrifuge has no response and cannot stop working. According to the analysis of the failure phenomenon, the failure should be in the stop control part of the control circuit part, which includes the stop switch, the power control board and the timer control board. Turn on the centrifuge, use a multimeter to check the stop switch, it is normal; after starting, measure the signal output from the power control board to the timer control board is AC 16V is normal, the fault should be on the timer control board, the timer control board can not execute the stop when the stop signal is obtained task. After troubleshooting one by one, it was found that the C9013 transistor on the timer control board and the capacitor with the model of 16V, 470μF broke down, and the new transistor and capacitor were worsened. The fault was eliminated.

★ After the power is turned on, the control panel displays normally. When the start button is pressed, the centrifuge works normally. But when the stop switch is pressed, the centrifuge cannot stop working immediately, but slowly stops after spinning for a long time. According to the analysis of the fault phenomenon, the fault should be in the stop brake control part of the control circuit part. The brake control part includes the model: WJ176-12V intermediate relay, the brake resistance R: 20-30Ω, the model: KBPC50A10M silicon stack and wire . Turn on the centrifuge and use a multimeter to measure the brake resistance, intermediate relays and wires. They are all normal. After turning on the machine, press the stop button and use the multimeter to measure the 4 corners of the silicon stack. There is AC 12V input but no DC 12V output. It is judged that the silicon stack is broken and replaced. New, troubleshooting.
