Guoqiang CCZ20 Mine dust sampler

I. Overview 1 Features mine dust sampler used by high performance suction pump, automatic time control circuit, flow control circuit, automatic feedback constant current circuit, undervoltage protection alarm circuit, power supply and other safety components. With no pulsing air, vacuum, load capacity, automatic timed sampling, safe, reliable, durable, easy to use features. It can be widely used in industrial and mining enterprises, labor safety, health and environmental protection departments, measuring the concentration of floating dust in the ambient air. 2, product performance standards GB 3836 "explosive gas environment with electrical equipment" GB / T 20964-2007 "dust sampler" Q / SD 003-2009 "CCZ2 type of individual dust sampler" Second, the main technical parameters of the project: Technical Parameters Sampling Traffic: 2L / min flow sampling error: ≤ ± 5.0% FS Sampling flow stability: ≤3.0% FS (8h within) Load capacity: ≥1000Pa continuous working time: ≥8h working noise: ≤65dB (A) sampling head airtight resistance: at 1000Pa pressure, pressure changes within 1min shall not exceed 100Pa meter accuracy: not less than 2.5 Battery group: Model QNY AA NiMH battery pack 1.2Ah × 5, the battery in series 3.06Ω / 10W (the six 0.51Ω / 10W resistor in series) of the current limiting resistor, and with epoxy potting as a whole, constitute intrinsically safe battery pack: Ue = 6V, Uo = 7V, Io = 2.0A, its maximum surface temperature ≤ 150 ℃ Explosion-proof type: Mine intrinsically safe (ExibⅠ) Dimensions: 120 × 80 × 42 Weight: 0.45kg Environment: Operating temperature: Underground (0 ~ 40) ℃; ground (-10 ~ 40) ℃; relative humidity : ≤95%; Atmospheric pressure: (86 ~ 110) kPa; three sets of 1, samplers host 1; 2, a sampling head; 3, leather case 1; 4, charger 1; 5, 1 filter paper box; 6, membrane sandwiched 5; 7, a screwdriver; 8, forceps 1; 9, connecting hose 1; 10, an instruction manual; 11, certificate 1.
