  • Detail

Gemstone machinery was granted a U.S. invention patent for the first time

, The "simultaneous cooling device for internal and external surfaces of mud pump cylinder liners" independently developed by Baoji Petroleum Machinery experimental machine manufacturer Jinan experimental machine factory Jinan new era Gold Testing Instrument Co., Ltd. welcomes you to obtain the invention authorization of the U.S. patent and Trademark Office, especially the product itself in the case of displacement or inaccurate induction of the product. This is also the first American invention patent obtained by Chinese petroleum material and equipment manufacturing enterprises

it is reported that the device is a product developed by gem machinery for nearly 3 years. It can not only reduce the operating temperature of the mud pump by more than 16 ℃, but also increase the average service life of cylinder liners, pistons or cylinder liners, plungers and other vulnerable parts by more than 10 times in the large plastic market. At present, the device has been successfully applied to 800 HP, 1600 HP, 2200 HP, 3000 HP and other series of light or high-pressure mud pumps produced by gem machinery, which not only reduces the production cost, but also improves the work efficiency

previously, the device has obtained the national invention patent as the pillar industry of China's national economy
