XA-120 Medium Flow Particle Sampling Pump
1、 Execution standards
JJG943-1998 "Total Suspended Particle Sampler"
HJ/T374-2007 Technical Requirements and Testing Methods for Total Suspended Particle Samplers
2、 Purpose:
The sampler uses the XA-120 medium flow particulate matter sampling pump produced by our company as the pumping power. This pump has been widely equipped by environmental monitoring, labor health, scientific research and other departments in major systems across the country. It has been tested under long-term and sometimes harsh conditions, proving its excellent performance and reputation for reliability and durability, and has been well received by users.
3、 Characteristics
1. The sampling pump is self-lubricating, has low noise, and can operate continuously.
2. Optional PM10 cutter for PM10 sampling, optional PM2.5 cutter for PM2.5 sampling.
3. The optional dual membrane sampling head can meet the requirements of HJ-480-2009 Determination of Fluoride in Environmental Air for oxide sampling.
4、 Technical parameters
1. Flow range; 60 L/min～120L/min
2. No load flow rate: ≥ 130L/min.
3. Ultimate vacuum degree: ≥ 60KPa
When the power supply voltage is AC 220V ± 10% and the filter membrane load changes from 3.0Kpa to 6.0KPa, the average pumping speed of the sampling port is 0.3m/s ± 5%;
5. Sampling head filter membrane diameter: φ 90mm;
6. Fault free working time>2000h;
When the ambient temperature ranges from 10 ℃ to 35 ℃ and the relative humidity is ≤ 85%, the insulation resistance of the motor terminal to the casing or ground is greater than 20M Ω.
