The operation and maintenance of CEMS (online flue gas monitoring system) is a key technical service to ensure the accuracy and reliability of environmental monitoring data and the stable operation of the system, covering daily patrol inspection, fault handling, calibration and verification, quarterly maintenance, technical renovation and overhaul, and compliance management, so as to ensure that the monitoring data meet the requirements of environmental protection assessment.

The operation and maintenance of online water quality monitoring equipment is a professional technical service to ensure the stable operation of the automatic water quality monitoring system and the accurate and reliable data. Its core is to achieve the full life cycle management of equipment through standardized processes, covering daily patrol inspection, fault handling, calibration and verification, quarterly maintenance, technical renovation and overhaul, and compliance management, so as to ensure that the monitoring data meets the requirements of environmental protection assessment.

The maintenance service of industrial automation instruments and DCS (distributed control system) is the core link to ensure the safe, stable and efficient operation of the production process, which covers preventive maintenance, fault emergency treatment, system optimization, technical renovation and maintenance, personnel training, etc., and regularly carries out zero calibration, range calibration, and loop testing (from field instruments to signal joint debugging in the control room) to ensure measurement accuracy and control stability.

Installation and commissioning is an important link to ensure the normal operation of equipment, which involves the on-site installation of DCS control system and electrical instruments, system joint commissioning, functional testing, technical renovation and maintenance, and operation optimization. Technicians complete the equipment positioning, pipeline connection, electrical wiring and software configuration according to the design drawings and operating specifications, and simultaneously carry out single machine commissioning and linkage testing to ensure the functional integrity and operational reliability of the equipment and help the project to be put into efficient operation.
