ZDA-ZXF-01F type resuspension sampler Introduction: The ZDA-ZXF-01 particle resuspension sampler is mainly composed of a control system, a sample delivery system, a resuspension chamber, an air filtration system, a cutter, a pneumatic control system and external connection components. Among them, the sample delivery system sends the dried and sieved particles into the suspension tank, and simulates the resuspension environment by using the aerodynamic principle of particulate suspension. The suspension tank is a sealed box in which the particulate matter is resuspended in the atmosphere. The four well-distributed openings provide clean air to the suspension tank. The cutter completes the sampling of the PM10 and PM2.5 by different cutting heads. The control system is the source of power for resuspension and provides an experimental environment that meets the sampling requirements of the cutter through controllable components. Reference standards and specifications: Guide to Technical Analysis of Sources of Atmospheric Particulates (Trial) "Technical requirements and test methods for ambient air particulate matter (PM10 and PM2.5) samplers" Features: (1) It can simulate the process of the pollution source sample entering the atmospheric environment, complete the sampling of the open source sample, and facilitate the relevant analysis; (2) The powder sample can be sampled and sampled with different particle sizes such as PM10 and PM2.5. The four-channel design can be combined with PM10/PM2.5 sampling. The sampling channel is flexible and can be freely selected and can be used as a parallel sample. The sampling module satisfies the source spectrum analysis requirements; (3) It has high sampling efficiency, simple and economical operation, and has high practical value for unorganized emission source spectrum analysis. Good sampling parallelism and stability can effectively distinguish the characteristics of each emission source; (4) The system has self-diagnosis and safety protection functions, which can monitor the experimental environment and process in real time, and have automatic alarm functions such as humidity, temperature, pressure and flow when abnormal environmental parameters occur; (5) Segmented unique structure design, the sample is quickly and evenly mixed with fresh clean air, the sampling efficiency is higher, and the suspension tank and sample compartment are convenient for quick cleaning; (6) Spring-pressed secondary retention sedimentation filter holder design (patented design), good sealing and uniformity, easy and quick film change; (7) The suspension chamber is electropolished and polished stainless steel to withstand sufficient pressure; (8) Full-automatic operation data acquisition and control system, one-button start, data automatic recording and sampling, automatic recording of sampling process data (flow, temperature, humidity, pressure, time), generate sampling report, system data is permanently saved and stored 10 Annual data. (9) Fully imported high-precision mass flow control system, multi-point control, stable and reliable sampling; (10) All imported sampling pump, high load and large flow, equipped with frequency conversion system, shock absorption and noise reduction design, high precision control, stable operation and low noise; (11) Fully imported air filtration and dehumidification system, high filtration, dehumidification efficiency, stable operation and convenient maintenance; (12) Touch screen operation, convenient for sampling data setting, storage, export, printing, can automatically complete the calculation and conversion of working condition volume and standard condition volume, and the human-machine interface dynamically displays the sampling process; (13) Full-automatic monitoring of the sampling process, real-time display of faults, single point test can be realized, and the fault point can be judged; (14) Standard Ethernet communication interface, USB data interface support data download, remote fault diagnosis, remote system upgrade;
