1.Electrical vacuum drying oven common faults and troubleshooting methods 1 Vacuum can't pump 2 Large temperature fluctuations 3 Not warming up 4 Temperature control failure temperature rise 2. Common Faults and troubleshooting electric oven blast 1 Not warming up 2 After the temperature reaches the set value, it still surges sharply. 3 Temperature fluctuation is too large 4 Poor temperature uniformity 5 III, IV type box is charged 1.Electrical vacuum drying oven common faults and troubleshooting methods Serial number Fault phenomenon the reason Method of exclusion 1 Vacuum can't pump 1 seal aging failure Replace the seal. Seal the strip as far as possible from the organic solvent and its atmosphere. 2 vacuum pump failure Replace the vacuum pump 3 doors are not closed Re-tighten and gently push the glass when vacuuming begins. 4 vacuum gauge vacuum shows illusion. Replace the vacuum gauge 2 Large temperature fluctuations 1 large external power supply voltage change Take voltage regulation measures to meet the power supply requirements of the equipment. 2 temperature control instrument drift Replace the temperature control instrument. 3 Not warming up 1 heater circuit breaker If the wiring is broken, the fault may still be replaced. 2 sensor open circuit After the wiring is disconnected, the fault may still be replaced after the sensor is replaced. 3 relay open circuit If the wiring is broken, the fault will still be replaced and the contactor will be replaced. 4 temperature control meter is not set Reset the temperature control instrument according to the requirements of the manual. 4 Temperature control failure Temperature rise 1 sensor short circuit If the wiring is shorted, the fault may still be replaced after the sensor is replaced. 2 relay short circuit Replacement relay 3 temperature control instrument failure Replace the temperature control instrument. Collagen is the most abundant protein in mammals, accounting for 25% to 30% of the total protein. It is widely present in all tissues from the body surface of lower vertebrates to mammalian bodies. Collagen monomers are long cylindrical proteins with a length of about 280 nm and a diameter of 1.4–1.5 nm. It consists of 3 polypeptide chains that are supercoiled around each other.
