AKFC-92A-type dust sampler 20L / min

AKFC-92A-type dust sampler main technical indicators: 1, sampling flow: 20L / min 2, suction vacuum:> 3000Pa 3, load capacity: ≥1000Pa 4, mining dust Range: Full dust, respirable dust 5 , time range: 0 to 99 minutes in any setting 6, continuous working time:> 120min 7, the operating noise: ≤70dB (A) 8, explosion-proof type: Mine intrinsically safe ibI (150 ℃) 9, Applications: Temperature -5 ~ 35 ℃ Relative humidity ≤95% RH 10, Dimensions: 200 × 140 × 80mm 11, Instrument Weight: 1.8kg Second, product information: AKFC-92A-type dust sampler is based on "MT162-1995 by dust sampler technical conditions "," JJG (coal) 03-96 mine dust sampling test procedures "," GB16225-1996 air of workplace health standards for respirable silica dust "," GB16238-1996 shop air to breathe cement dust hygiene standards " , "GB16248-1996 air of workplace health standards for respirable coal dust", "GB5748-85 workplace air dust measurement method" "MT79-84 Inoue workplace under the selection and arrangement of the measuring points, dust concentration and dispersion of Determination, "the design and manufacture, is a method for measuring the ambient air concentration of dust floating in conventional instruments. Suitable for dust monitoring industrial and mining enterprises, labor safety, labor hygiene and environmental protection sectors. The dust sampler consists of high performance suction pump, automatic time control circuit, flow control circuit, automatic feedback constant current circuit, undervoltage protection alarm circuit, safe power supply and other components, also has a variety of pre-trap dust. Which is used to determine the total dust concentration in the whole pre-trap dust; another method for determining the concentration of respirable dust impact pre-trap, such a pre-trap can harm the body's respiratory and non-respiratory dust dust separation, can an acquisition can have both respiratory and respirable dust samples of two non, the separation efficiency of the internationally recognized "BMRC" standard curve, is a more reliable and practical dust pre-separation device. The instrument uses ibI (150 ℃) grade intrinsic safety explosion-proof structure, especially for coal mine and other workplace containing explosive hazardous gases. The machine chassis with a high-strength ABS plastic, and made moisture-proof, dust-proof, anti-static and other special treatment. The instrument has no pulsing air, vacuum, load capacity, automatic timed sampling, safe, reliable, durable, easy to carry and field use, etc., the main technical indicators have reached or approached the international advanced level.
