Biochemical incubator maintenance method
The biochemical incubator may encounter some minor faults during use. If you encounter a fault, you can check the accompanying instructions first. The general manual contains the biochemical incubator maintenance method . The following is a description of the troubleshooting of biochemical culture and biochemical incubator maintenance methods for Shanghai Dongsheng Instruments : Fault phenomenon Reason for failure Troubleshooting No power at boot (Light does not shine) The power outlet has no power or has poor contact with the plug repair Box power cord is broken or plug is not plugged in Repair, reinsert Power switch is broken (or not open) Replace and open the power switch Fuse off If the power is still blown after the change, it is necessary to check whether the motor and other components are short-circuited (the motor has bad odor, the wire package is black, etc.) or the through-shell (insulation resistance is 0). Meter no display Wiring off or instrument burnout Reconnect the wires or replace the meter the meter shows "- - - -" The sensor is broken or the wiring is broken (falling off) Repair or replace Pt100 (100Ω, 0.3Ω/°C at 0°C) Temperature value is out of control range Use the appropriate temperature value within the specified value Not cooling The switch is not in the correct position Set the correct position Compressor is broken or pipeline blockage or R12 leak Replace, block, add R12 Compressor overheat protector start When the compressor temperature drops, it naturally recovers Compressor protector burned out (burnt smell) Replacement protector The temperature is out of control and AL1 alarm light is on AL1 setting is incorrect Reset Two-way thyristor is broken down Temperature controller is bad (AL1 alarm light is off) Replace the temperature controller Not warming up Large temperature control error Or have a static difference Temperature controller is bad HEAT light bright two-way thyristor non-conducting Replace the temperature controller The timing function is used, and the temperature rises and then falls. Make T1≠0 Not warming up Large temperature control error Or have a static difference The fan is broken (not turning) Replace the fan Pt100 has poor contact and the resistance becomes larger Rewiring Parameter (HL, SC) setting is incorrect Reset PID and other parameters are set incorrectly Re-adjust parameters The condenser has too much frosting and low cooling power Warming down Fan sound is abnormal Or noisy (greater than 70db(A)) The fan is broken or the compressor fan is broken. Replace the fan Rub the rear duct plate or the fan blade Repair, replacement If abnormalities, smells, smog, etc. cannot be handled during use, please turn off the power immediately. Users should not blindly repair. They should inform Shanghai Dongsheng Instrument Equipment Co., Ltd., and the repairs are provided by professionals. We provide home repair service.
Titanium alloy has high strength, low density, good mechanical performance, good toughness and corrosion resistance.The process performance of titanium alloy is poor, the cutting process is difficult, in the hot processing, it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen and carbon.There is also poor wear resistance and complex production process.Industrial production of titanium began in 1948.The need for the development of the aerospace industry has enabled the titanium industry to grow at an average annual growth rate of about 8%.The annual production of titanium alloy has reached more than 40,000 tons, nearly 30 kinds of titanium alloy.The most widely used titanium alloys are ti-6al-4v (TC4), ti-5al-2.5sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).
Titanium Parts is the workpiece is fixed on the lathe, using high speed rotating machine drives the workpiece to turning. tool on the workpiece so the product shape is round.The processing materials are commonly used in steel. The machining precision is 0.01mmand concentric 0.01mm of the CNC Turning Machining. we have specialized equipment to test products, these instruments include: TESA Grohe, micrometer, projector, calipers. Product surface treatment has polishing,brushing, powder coating, laser engraving LOGO, etc.
