ST-03 image of the surface pore size analyzer Bo circuit fault and the treatment of common Failure. Huan 2 thermal conductivity cell failure and troubleshooting (z) disconnect the power. Cha Chi balanced bridge. Specific methods are as follows: after opening the instrument panel, the thermal conductivity cell incubator five o'clock on a certain block wiring board with a multimeter check the resistance between 1-2,2-3,3-4,4-5. Each block box should be around 5011. If the resistance is great. Hot Received Date: 2ooo a 06-09 lead unit of the corresponding pool of Troubles and methods are listed in Table 2. (3) Check the pool balance adjustment potentiometer is normal or not rhyme. If the potential negative performance, replace the potentiometer. In addition, the recorder itself, failure, maintenance recorder. 1.2 Failure 2: Failure disproportionate attenuation and treatment: The instrument output attenuation using \Consists of 9 files (respectively, 1 / 2 \the right to see the House that there is a point of not more than 1000's output resistance. not by the attenuation is due to decay than the side of the variable resistance resistor. processing method is first used to observe the law. see \have cast a fracture, the phenomenon of burning black. Second multimeter test method used to identify variable resistance resistor, the replacement of the same type of resistance. 1.3 Troubleshooting 3: baseline \Huan 3 and fault troubleshooting 1.4 Fault 4: pool balance transfer bad failure causes and treatment methods: first with two 4.7kn potentiometer replacement in the 2 car hesitate 2k resistor (potentiometer resistance adjustment 0.8k-2k range control in between). gradually adjust the effective resistance of the potentiometer. observe the pool balance reconciliations, until you find a suitable resistance, and then replaced with two equivalent resistance 2 2k resistor. If by the experiment. pool balance transfer still is not good, then thermal conductivity should be replaced per 9 2001 59 * light metal fluoride salt factory's main environmental problems and countermeasures Xu Qing (magnesium and Design Institute, Shenyang, Liaoning, Shenyang 110001,ugg milano, China ) �� To: Ting built of wood of the technical status of the salt factory. cuddle on the existence of the ring are analyzed. From the high level of sustainable presented an insanity Park. straight to the mushroom and the construction of the Community Relations t tune: fluoride salt; environmental protection; can see the cup special morning; leaves mushrooms in the field sub-Lou Columbia: x3 labeled {fl von literature: B article {� No. :1002-1752 2001) 09-8059-051 fluoride production technology situation of China 2 Environmental issues Analysis of fluoride products are mainly cryolite Na3AlF) and aluminum fluoride fluoride industry is heavily polluting industries, the environmental problem (AIF ~) two. 60 years ago, domestic and industrial raw fluoride gradually valued by the people. produced only by fluorite (ca) the wet production process as raw materials. into the fluoride salt factory to find out the main environmental problem is after the end of 60 years. With the increasing requirements for fluoride . Taiwan fluoride fluoride-depth analysis of the production process. the production technology has also been growing rapidly. But the development speed of the existing wet process 2I degree of environmental protection is lagging behind,ugg italia, yet no big change, big Most fluoride fluoride salt factories still wet production. its relatively backward technology and equipment. to 60 years of production technology to maintain production, technology, equipment behind the process can be divided by the oxygen from the acid fluoride preparation, preparation of cryolite and the low level of fluoride action, environmental issues more. Only very few plants prepared using the first three parts of aluminum. the process and the nodes are shown in Figure sewage into the technology, such as Xiangxiang fluoride salt factory in the early 90s the introduction of the Swiss Technology 1 La, Yan Wang date won! On respect: | Robinson * Gan twenty twenty * **** **** twenty twenty twenty twenty twenty-bashing *** {ten twenty * twenty * twenty Gan flutter *_*** shaking * Twenty pieces of components because of thermal conductivity with long, tungsten temperature coefficient of thermal components will change,air jordans, resulting in unbalanced bridge output, adjust the effect of pool balance. 15 Fault 5: Constant Temperature can not maintain the target temperature of the l constant temperature control circuit apparatus shown in Figure 1. prince Yu l Block diagram of temperature control unit failure causes and treatment methods, such as shown in Table 4 closing date of 20 1-03-12 prayer Failure atlas 4 Conclusion and treatment 2 (1 ) repair large and medium-sized instrument,air jordan shoes cheap, they can follow the first block of the fault and then locate the precise location of the fault principle, allowing of much smaller, to avoid all the circuits of the instruments to improve maintenance efficiency. (2) in the maintenance of Power can be taken off-line measurement and method of combining static measurement, the failure to obtain access for more information. improve the accuracy of fault location.
