How to do the test report? Why do you need to do product inspection? Third-party testing institutions provide product testing services in various industries, and there are many cooperative laboratories across the country, mainly serving companies, enterprises, individual businesses, universities and scientific research.
Report qualification: CNAS, CMA, CAL, etc
. Presentation style: electronic
version of the testing cycle: 3-15 working days (expedited can be expedited)
Testing cost: Quotation according to customer needs and experimental complexity
Sample size: Choose to send samples or visit the door according to the sample size
A compressor is a driven fluid machinery that elevates low-pressure gas to high-pressure gas, and is the heart of a refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and then exhausts high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thereby achieving a refrigeration cycle of compression, condensation (heat release), expansion, and evaporation (heat absorption). A linear compressor uses the principle of magnetic levitation and a spiral ring fluid dynamics structure to compress gas and provide power for refrigeration. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. A piston compressor is generally composed of a shell, an electric motor, a cylinder body, a piston, control equipment (starter and thermal protector), and a cooling system. There are three cooling methods: oil cooling, air cooling, and natural cooling. Linear compressors do not have shafts, cylinder bodies, seals, and heat dissipation structures. The compressors of general household refrigerators and air conditioners are powered by single-phase AC power, and their structural principles are basically the same, but they use different refrigerants
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problems100% inspection and testing process:
