Baijian Testing is mainly engaged in textile, insulation, cosmetics, food, hardware industry related product testing, as well as providing product certification services, but also in the broadening of the scope of the testing industry, the laboratory issued a report can be stamped CNAS/CMA/CAL qualification seal, the report is true and effective.
Report qualification: CNAS, CMA, CAL, etc.
Testing costs: Quotation sample size according to customer needs and experimental
complexity: Choose to send samples or come to the door according to the sample size
An air compressor is a device used to compress gases. The construction of an air compressor is similar to that of a water pump. Most air compressors are reciprocating plug type, with rotating blades or screws. Centrifugal compressors are a very large application. There are many types of air compressors. 1. According to its working principle, it can be divided into three categories: volumetric compressors, power compressors (speed or turbine compressors), and thermal compressors. 2. According to lubrication methods, it can be divided into oil-free air compressors and oil lubricated air compressors. 3. According to performance, it can be divided into low noise, variable frequency, explosion-proof and other air compressors. 4. According to their usage, they can be divided into: refrigerator compressors, air conditioning compressors, refrigeration compressors, oilfield compressors, natural gas refueling stations, rock drills, pneumatic tools, vehicle braking, door and window opening and closing, textile machinery, tire inflation, plastic machinery compressors, mining compressors, marine compressors, medical compressors, sandblasting and painting compressors. 5. According to the type, it can be divided into fixed type, mobile type, and closed type. Positive displacement compressor - a compressor that directly increases gas pressure by changing the gas volume. Piston type compressor - is a displacement type compressor, whose compression component is a piston that performs reciprocating motion within the cylinder. Rotary compressor - is a positive displacement compressor, where compression is achieved by the forced movement of rotating components. Sliding vane compressor - is a rotary variable capacity compressor, where the axial sliding vanes slide radially on the rotor that is eccentric with the cylinder body. The air trapped between the slides is compressed and discharged. Liquid piston compressor - is a rotary displacement compressor in which water or other liquids act as pistons to compress gas and then discharge the gas
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report

1, sending samples
2, checking requirements
3, targeted quotation
4, both parties determine, sign a contract, start
the experiment5, complete the experiment: the testing cycle (can be expedited) will be changed according to the sample and its testing items / methods, you can consult the engineer
6, issue a test report, and provide post-service.
