First, temperature and humidity are important factors that affect the performance of the instrument. They can cause mechanical components to rust, reduce the smoothness of the metal mirror surface, cause the error or performance of the mechanical part of the instrument to decline; cause the aluminum film of the optical components such as gratings, mirrors, and focusing mirrors to rust, resulting in insufficient light energy, stray light, Noise, even the instrument stops working, thus affecting the life of the instrument. Maintenance should be regularly corrected. There should be an equipment room with four seasons of constant humidity, equipped with a constant temperature device, especially a laboratory located in the southern region.
Second, dust and corrosive gases in the environment can also affect the flexibility of mechanical systems, reduce the reliability of various limit switches, buttons, and optocouplers, and it is also one of the reasons that aluminum films must be rusted. Therefore, it must be cleaned regularly to protect the environment and the instrument's indoor sanitary conditions and prevent dust.
3. After the instrument has been used for a certain period of time, a certain amount of dust will accumulate inside the instrument. It is advisable for the maintenance engineer or the engineer to periodically open the instrument housing to clean the interior of the instrument, and at the same time re-tighten the radiator of each heating element. The sealed window of the box is cleaned, the light path is calibrated if necessary, the mechanical part is cleaned and the necessary lubrication is made. Finally, the original shape is restored and some necessary tests, adjustments and records are performed.
The carbon-sulfur analysis instrument uses an electric arc burner to burn the sample, and the gas capacity is legally carbon and the iodine method is used to automatically titrate and determine the sulfur. Xinyao Analytical Instrument is fully automatic with carbon and sulphur determination; imported precision micro-pressure sensor and microcomputer programming automatic control working procedures, detection and measurement results, so that carbon and sulfur element content can be directly read and print measurement results automatically. The electronic balance was connected with the microcomputer to realize the quantitative analysis of carbon and sulfur analysis. It is suitable for the determination of carbon and sulfur in various materials such as carbon steel, high-middle-low alloy steel, stainless steel, cast iron, ductile iron, alloy cast iron, and ferromanganese.
Therefore, in addition to the precautions listed above, the maintenance of carbon-sulfur analyzers should also pay attention to the following points:
1. The electric arc furnace must clean the dust every day. The cleaning site is inside the furnace body and the dust collector. It is found that the damage of the dust removal paper should be replaced immediately. Napkin or other paper cannot be used instead.
2. Whenever the measuring cylinder on the analysis box and the two electrodes on the buret do not touch each other, otherwise the instrument program cannot operate normally. 3. Whenever the rubber stopper on the buret tube must open a notch, otherwise the titrant is added. Do not go.
4, sensor to add silicone oil to protect the sensor, or easy to corrosion.
5. Avoid strong vibration or dampness. Turn off the oxygen main valve and the instrument power supply when you are off work.
As the name implies, Round Molded Graphiteis a cylindrical product of graphite electrode, which is made of graphite block materials by crushing, screening, batching, shaping, cooling, roasting, dipping and graphitization of post section petroleum coke and medium temperature coal tar pitch. It has the advantages of high temperature resistance, corrosion resistance, good conductivity and light weight. It is mainly used for large DC resistance furnaces, blast furnace bricks, conductive electrodes, lining anti-corrosion and other purposes.
The high-purity graphite, graphite block and Molded Graphite produced by Pingdingshan Carbon Graphite Factory for many years are excellent, and the specifications of Round Molded Graphite are as follows: φ 450*800, φ 520*400 φ 630*420, φ 660*620 φ 780*600, φ 820*350~500 φ 900*350~400, φ 1050*350~400 φ 980~350*400, φ 1160*350~680 φ 1260*350~680, φ 1330*400 φ 1420*400, φ 1520*400 φ 1630*350, φ 1800*350 φ 2000*350, φ 520~2000*680
