The direct-reading spectrometer can be maintained for more than 5 years.

With the rapid development of industrial technology, direct-reading spectrometers are widely used in metallurgy, foundry, machinery, scientific research and other major industries. As after-sales staff of direct-reading spectrometer manufacturers, we will encounter various problems from customers. However, Summarizing the reasons, there are many failures that are not caused by the instrument itself, but are caused by improper and incorrect operation by the operator. Below I will take everyone to understand the matters that should be paid attention to and the problems that are easy to encounter during the operation of the direct reading spectrometer.

        I. Environmental requirements
        1. Ambient temperature: generally 15 ℃ -25 ℃ is suitable;
        2. Ambient humidity: relative humidity 20-80%;
        3. Dustproof: prevent harmful solid dust from entering the instrument and operating environment;
        4. Power supply requirements: The power supply voltage is not allowed to fluctuate greatly, and it is best to equip it with a regulated power supply;
        5. Electromagnetic interference: The resistance of the ground wire should be small. Keep it away from large strong electrical equipment to reduce interference.
        Operational precautions
        After the instrument is turned on, the vacuum level meets the requirements, and the sample can be analyzed after high pressure is added. To achieve the best state, it takes more than four to six hours to stabilize, so the spectrometer should not be turned off unless it is not used for a long time.
        1. The first thing we do every day is to preheat the instrument. Generally, the waste samples are stimulated about 10 times. The cast iron may take longer.
        2. Stimulate a standard sample with a specific content and check the accuracy of the instrument. If it is not ideal, standardize it, then do a sample calibration and then analyze the sample. Under normal circumstances, it is recommended to perform sample control calibration every day, trace around 15 days, standardize once every 2-3 days, and clean up the spark table around 7 days (if a large number of samples are excited every day, you need to clean up in time).
        Third, the correct sampling and preparation
        In addition to the accuracy of the data, the accuracy of the data is closely related to sampling and sample preparation.
        1 Preparation of test specimens: The samples should be representative and free of pores, cracks, trachoma and slag inclusions.
        2 Grinding of the sample: it should be smooth, textured, and it should not be touched by hand after being ground, and should not be stained with water or oil.
        3 Excitation point: The excitation point of the circular sample is 1/2 of the radius, and the excitation point of the irregular sample is 1/2 of the diagonal (cannot be excited multiple times at the same location).
        Fourth, the maintenance of the spectrometer vacuum pump
        Vacuum pump is one of the supporting equipment of our spectrometer. Many customers only pay attention to the instrument itself and often ignore the maintenance of supporting equipment. However, the maintenance of the vacuum pump is also an important part.
        1. Check the oil quality and oil level in the pump daily.
        2. Check if the vacuum pump is leaking oil every week, and use the air gun to clean the dust and debris left on the air intake filter.
        3. Check the function of the exhaust filter every month for smoke and fuel injection.
