9. Cái gì làm chữ cái in the chống cháy nổ cấp Exd II CT6 đại diện?
Ex explosion-proof public mark d Flameproof type (electrical equipment with flameproof enclosure) Class II: all electrical equipment used in explosive gas environment except coal mine and underground. C: It refers to the ignition energy uJ, 280,>180,60... 80,<60. T6: refers to the temperature group, T6 is 85 degrees.
Online gas analyzers should be widely used in complex working conditions, as the moisture, dust, high temperature, etc. of the sample gas can have various impacts on the detection of the instrument. Through the pre-treatment system, the sample gas can be sampled, insulated, degreased, dusted, condensed and dehydrated, pressurized or depressurized, constant flow, and pressure, and then sent to the gas analysis instrument for testing, ensuring the accuracy and stability of the measured values.
11. What are the principles of online oxygen detectors for detection?
Zirconia, Điện hóa, thuận từ, Laser
12. Tại sao là it cần thiết to fill out the background gas composition in detail in in industrial and mining survey form?
13. Cái gì vai trò không xoáy bình ngưng phát in tiền xử lý?
Under what circumstances do pressure reducing valves need to be used in the pre-treatment of online gas detectors? Under what circumstances does a suction pump need to be used?
Khi the sample gas pressure in the pipeline is greater than % 7b% 7b0% 7d% 7d.2MPa% 2c a áp suất giảm van nên be sử dụng. Khi nào the áp suất is less than 50KPa% 2c a hút bơm nên be sử dụng.
What are the types of dust removal steps in the pre-treatment of online gas detectors?
Nói chung, có are ba levels of filtration: sampling probe filtration, pre-treatment filter, and analytical instrument fine filtration. The specific configuration depends on the actual working conditions.
16. Cái gì là the general setting of the oxygen deficiency alarm point for the oxygen gas detection alarm device?
18.5 phần trăm VOL
If the analytical instrument pipeline is in a vibration state, which detection principle cannot be used?
Laser nguyên tắc và thuận từ nguyên tắc
