◆ Maintenance significance

The laboratory is like a 24-hour running machine, which needs regular or irregular professional maintenance to effectively increase the service life of the laboratory and improve the use efficiency.

◆ Maintenance content

◆ Laboratory HVAC system operation and maintenance services

Hvac system mainly includes heating engineering, ventilation engineering, air conditioning engineering and water supply and drainage engineering, etc., through regular inspection, investigation, testing and debugging, consumables replacement and other ways to ensure that the laboratory HVAC operation is normal, to ensure the environmental comfort of the laboratory working area, the effective removal of harmful waste gas, pipe and valve parts work normally.

◆ Laboratory electrical system operation and maintenance services

The strong current system is the power source for the normal operation of the laboratory. Through maintenance, potential faults are investigated, aging components are replaced, and power protectors are regularly reset, etc., to ensure the normal use of dual circuits, UPS, grounding system, explosion-proof, emergency power failure, weak current system, and quick-plug interface, screen for line damage, corrosion, loose connections, and optimize distribution load.

◆ Laboratory gas supply system operation and maintenance services

Regular maintenance of the central gas supply system, through the special gas equipment such as gas storage tank, transmission pipeline and valve control components of daily inspection, regular testing, etc., to ensure that the pipeline no leakage, alarm device sensitive, quick plug interface safety, emergency exhaust normal;

According to the provisions of the "Combustible gas detector" (GB 15322.2-2019), the detection cycle of the combustible gas detector (acetylene, methane, propane, etc.) should be determined according to the use environment, use conditions and test results, generally not more than 12 months, so it is recommended to calibrate once a year.

◆ Laboratory automatic control system operation and maintenance services

Laboratory automatic control system mainly includes fresh air system control, exhaust system control, environmental monitoring, purification system control, cold storage and constant temperature and humidity system control, etc., through regular inspection and investigation of electronic components, replacement of accessories, etc., to ensure that all kinds of laboratory systems control normal, accurate control parameters, automatic system logical setting, etc.

◆ Furniture and supporting facilities, equipment maintenance services

Experimental furniture system includes fume hood, test bench, high cabinet, biosafety cabinet, ultra-clean workbench, balance table, safety cabinet, etc., through regular maintenance, according to the change of the environment, timely adjust the material of accessories, such as the construction of the neutral environment, now for the acidic environment, furniture and accessories in the environment must be transformed into acid-resistant materials; Regularly check the airflow direction and surface wind speed of the biosafety cabinet and the biosafety cabinet, record and compare with the control panel, and adjust the value gap in time.

◆ Laboratory upgrade, renovation, relocation services

In the process of laboratory operation, the functional systems and equipment often fail or do not meet the needs of use, and need to be repaired or reformed. Provide timely, efficient and professional laboratory full-function system maintenance and upgrading; General laboratory relocation involves the relocation of experimental instruments and experimental furniture and the corresponding instrument 3Q verification, etc. Public and third-party testing and identification laboratories also need to re-conduct CNAS and CMA certification.

◆ Special laboratory and special facilities and equipment maintenance

In addition to the above independent functional system maintenance, some special laboratories need to maintain the overall performance of the laboratory, such as biosafety laboratories, purification laboratories, constant temperature and humidity laboratories, etc.

Such as: biosafety laboratory regular maintenance to ensure that the pressure gradient is normal, the enclosure structure is normal, the disinfection facilities are normal, the air filtration facilities are normal, the biosafety cabinet is normal, etc.

The purification laboratory is regularly maintained to ensure that the pressure gradient is normal, the envelope is normal, the cleanliness is normal, the air filtration facilities are normal, etc.

The constant temperature and humidity laboratory is regularly maintained to ensure that the constant temperature and humidity are stable and up to standard, and that the constant temperature and humidity units operate normally and consume reasonable energy.
