The technical solution provided is as follows:
The SPZY-5400 gas analyzer is a carefully designed electrical instrument equipment specifically designed for online continuous/sampling detection of gas composition. High reliability, equipped with world-class analyzer sensors, as well as advanced measurement technology and sophisticated sampling pre-processing combination, its characteristics are complete functionality, safety and reliability, low maintenance, easy operation, and long service life.




1. Performance and technical characteristics
A.Sampling and preprocessing device
a. Sample gas sampling
B.Sampling pipeline
C.Sampling pre-processing device
The preprocessing process is that after the sample gas is extracted or depressurized, a portion is purified through filters, dryers, etc. and sent to the instrument for measurement, while the other portion is vented through a bypass valve; The purpose of setting a bypass valve is to shorten the lag time; There are also specially designed valves and interfaces for switching between standard gas and sample gas in the gas circuit, making it more convenient and efficient to calibrate instruments, avoiding air pollution in the gas circuit, and saving the amount of standard gas used;
Sample purification pretreatment unit: a special filter component is used to thoroughly purify the sample gas, removing dust particles and acid mist from the sample gas; Composed of dryers, fine filters, etc. to complete fine level purification treatment; The sample is composed of a flow controller and other components for gas extraction and stable pressure and flow operation. Ensure that the sample gas undergoes a series of steps including purification, dust removal, dehumidification, pressure stabilization, and flow stabilization, with a filtration accuracy of up to 0.1 μ m. Send the tested gas that meets the requirements into the analytical instrument, ensuring the accuracy and long-term reliability of the instrument's operation.

◆working principle
◆ Installation and wiring
The installation work of this system mainly includes the installation of sampling pipelines and analysis cabinets. The environmental conditions should meet the requirements of normal sampling and normal working conditions in the technical characteristics. Only by using this system in the designated environment can the safe operation and normal functioning of the system be guaranteed.
Installation of analysis cabinet
The analysis cabinet should be installed on the ground, and the mechanical vibration at the installation location should be negligible.
The large components (such as analytical instruments) inside the analysis cabinet are disassembled and packaged separately. When installing, refer to the system analysis flowchart, assembly diagram of the analysis cabinet, and electrical wiring diagram.
Installation of sampling pipeline
◆Sealing performance of the system:The airtightness inspection of the system shall be carried out in accordance with the enterprise standards.
◆Grounding:In order to ensure safe operation and avoid electromagnetic interference, the analysis cabinet is reliably grounded through the grounding terminal, with a grounding resistance of less than 4W.
◆ Wiring:Referring to the electrical wiring diagram, the wiring terminals inside the analysis cabinet electrical box need to be externally connected or interconnected during on-site installation, and all other electrical circuits should be connected before leaving the factory. Before the system is put into operation, the external electrical circuits should be connected correctly and the connections on each component should be checked for looseness or detachment.
