In the context of "Made in China" and "Created in China", product quality, as the lifeline of manufacturing companies, has attracted the attention of many manufacturing companies. In the compressor industry, forward-looking companies in the market are planning to improve their product quality. GMCC has persisted in improving quality inspection for many years, realizing highly automated quality inspection in the industry, playing the "trilogy" of quality inspection with an attitude of excellence, and playing a role in promoting the overall quality of the industry.
01 "Three inspections", accuracy of 0.001 mm
Material analysis is one of the important production links of GMCC compressors. The accuracy of its parts will directly affect the life of the compressor and the cooling effect. Therefore, GMCC pays attention to incoming inspection, emphasizes parallel testing and production, and inspects parts in three stages.
GMCC has set up a special material inspection room to strictly manage incoming materials. It uses automated testing equipment to carry out routine inspections of dimensions, apertures, thicknesses and other parts of crankshafts, valve plates, and cylinders, and conducts data analysis. In the machining workshop, GMCC specially sets up inspection posts, and manual inspection of the finished parts by manual operation of equipment. In addition, GMCC also conducts sampling tests from processed parts-the GMCC quality control room is equipped with a variety of high-precision instruments to conduct special tests for different characteristics of different parts. For example, in the sampling test of the cylinder, the GMCC inspector puts the cylinder under test on the inspection table, activates the three coordinates, and the probe scans the data in a circular area to measure the circularity and aperture of the cylinder round hole with an accuracy of up to 0.001mm for automatic and efficient detection.

02 Process visual inspection to ensure quality, infrared scanning
Compressor parts manufacturing starts from the machining workshop. After the rough machining of the parts, multiple finishing processes are carried out in the winding workshop to realize the finished parts. The different parts are merged in the final assembly shop, and then the shell assembly, welding, cleaning and drying processes are performed. .
During the manufacturing process, GMCC installed visual inspection devices at multiple locations such as the production line-stator appearance inspection, rotor clearance inspection, rotor ring gauge inspection, center hole inner diameter inspection, etc., to truly synchronize production and inspection, and complete quality and quantity. Production tasks.
For example, in the rotor production line of the GMCC winding workshop, automatic equipment is used to complete the process from production to inspection. After the high-impact rotor core is inserted into the magnet, an automatic visual inspection is performed. The "eye of fire" of the infrared scanning system is automatically and efficiently identified The shape, aperture, weight and other information of the tested rotor are fast and accurate.

03Backed by the testing laboratory, strictly control the performance of the whole machine
GMCC works step by step. After implementing the parts inspection work, the inspection of the performance of the compressor is started. In the GMCC R & D and Testing Center, noise testing and analysis, compressor calorimeter test, compressor single durability test room, motor performance test room, air conditioner performance test room and other test laboratories are developed for compressor technology. And overall performance testing.
GMCC performs long-term continuous operation or on-off operation of the compressor in the endurance test. The combination of the harsh ambient temperature, suction pressure, exhaust pressure, and various speed operation times around the compressor totals the test time. Thousand hours. In the compressor noise test, the GMCC inspector simulates the operating state of the compressor connection detection equipment. After a period of professional testing, a data report is obtained. The report will show the test standards and the actual measured noise decibels. The GMCC monitors According to the report, the compressors which have not been up to date are repaired and improved.

By playing the "trilogy" of quality inspection, GMCC steadily embarked on the road of branded production and operation. In the future, GMCC will continue to uphold the development core of "responsibility, innovation, and technical quality". While strengthening the concept of sustainable development, it will continue to invest a lot of scientific research resources to comprehensively improve the compressor's "quality manufacturing" capabilities, optimize product performance, and create more users. Satisfied and more reliable compressor.
