收悉贵方21/4-20下午发来的照片。 我们判断I-II级和III-V

I received your photos from 21 / 4-20 pm. <br>We judge that the pinions of I-II and III-VI rotors are in good contact with the large gears and meet the assembly technical requirements of "contact marks are not less than 80% along the tooth width and not less than 55% along the tooth height. <br>Please complete the follow-up work of air compressor assembly according to the relevant technical requirements; at the same time, send the installation and debugging records of bearings, gas seals and shaft seals to us to understand the specific situation. <br>The specific test should be carried out in accordance with the manufacturer's operating instructions and our relevant mail.

收悉贵方21/4-20下午发来的照片。<br> 我们判断I-II级和III-VI级转子的小齿轮与大齿轮的接触情况良好，符合“接触斑痕沿齿宽不少于80%，沿齿高不少于55%”的装配技术要求。<br> 请贵方按相关技术要求完成空压机装配的后续工作；同时把轴承，气封，轴封的安装调试记录，发给我们以便了解具体情况。<br> 具体测试要按照生产厂的操作说明和我们的相关邮件进行。

We have received your photos on the afternoon of 21 / 4-20.<br>It is judged that the contact condition between the pinion and the big gear of the rotors of I-II and III-VI is good, which meets the assembly technical requirements of "the contact spot along the tooth width is not less than 80%, and the height along the tooth is not less than 55%".<br>Please complete the follow-up work of air compressor assembly according to relevant technical requirements; meanwhile, send the installation and commissioning records of bearing, air seal and shaft seal to us so as to understand the specific situation.<br>The specific test shall be carried out in accordance with the operating instructions of the manufacturer and our relevant emails.<br>
