How to deal with these failures in SF double glass reactor? SF double glass reactor It has an automatic up and down lifting device with simple operation The main engine rises by touching the up key, the main engine drops by touching the down key, and stops when the hand is off the key In addition, there are emergency hand wheels When the lifting motor fails, turn the hand wheel, and the main engine can also rise or fall The unique sealing structure and fine selected sealing materials have good vacuum performance The temperature is displayed by numbers and sensed by metal probes When the sensor is inserted into the heating tank, when the water temperature reaches the preset temperature, the heater power will be cut off automatically When the water temperature is lower than the preset temperature, the heating power will be turned on automatically In this way, the water temperature can be controlled alternately The hundred digit of the position switch of the temperature control meter must be set to "0" The heating tank is made of stainless steel, and the water temperature is automatically controlled by the temperature digital display Please use mercury thermometer to measure the water temperature directly When replacing, cut off the power supply first, and then open the seat cover to replace the fuse SF double glass reactor can be used in the determination of heavy metals such as lead, copper, pot, zinc, calcium, manganese, iron, mercury, etc it can also be used as a high-temperature, high-pressure, corrosion-resistant and high-purity reaction vessel, as well as organic synthesis, hydrothermal synthesis, crystal growth or sample digestion and extraction Before sample preparation, heavy metals, agricultural residues, food, sludge, rare earth, aquatic products, organic matters, etc are digested Therefore, SF double glass reactor is widely used in the research and production of petrochemical, biomedical, material science, geological chemistry, environmental science, food science, commodity inspection and other departments Common faults and causes of SF double glass reaction kettle: 1 Turn on the power switch and the indicator light is not on; if the external power supply is not connected or the contact is poor, ask a professional electrician to check the power supply and socket; 2 Short circuit of safety tube: put the power switch of SF double glass reaction kettle in the off position and replace the safety tube; 3 The power indicator light is on, but it does not rotate: the rotating shaft is rusty, stop using, and contact the supplier Motor and electrical box are in fault, 7-core plug is not connected, and 7-core plug is reconnected; 4 Vacuum disappears suddenly: glass is cracked, switch is damaged, check glass parts, and replace switch; 5 There is vacuum, but it cannot be extracted: sealing ring is worn, please replace sealing ring and switch if there is leakage in connecting vacuum switch; 6 Sometimes there is no dirt in vacuum: if there is dirt on the steel shaft, please remove the dirt Check the vacuum gauge and vacuum pump 7 Aging of vacuum hose: replace the vacuum hose for SF double glass reactor.
