钻头真空定量注油是七十年代国外钻头生产的新工艺,这一新工艺对于保证钻头压力补偿系统的可靠性,提高钻头轴承的寿命有着重要的意义。为了尽快掌握这一先进技术,加快我国钻头生产发展的步伐,我们最近用8(1/2)″密封滑动轴承钻头作了真空定量注油的尝试:1.试验设备:2X-1A 旋片式真空泵,热偶真空仪,真空注油换向阀,真空胶管φ13×10。2.试验情况:用我厂8(1/2)″密封滑动轴承钻头和美国8(1/2)″史密斯钻头反复做了二十多次试验,基本上实现了钻头真空注油。我们做的试验属两类:第一类是单项试验,目的是确保设备能
Vacuum quantitative bit oiling is the seventies foreign bit production of new technology, the new technology for ensuring the reliability of the bit pressure compensation system to improve the life of bit bearings is of great significance. In order to grasp this advanced technology as soon as possible and speed up the pace of the development of bit production in our country, we recently tried to use 8 (1/2) “sealed plain bearing bit for vacuum quantitative oiling: 1. Test Equipment: 2X-1A Rotary Vane Vacuum Pump , Thermocouple vacuum instrument, vacuum oil-filled reversing valve, vacuum hose φ13 × 10.2 Test situation: use our factory 8 (1/2) ”sealed sliding bearing bit and the United States 8 (1/2)" Smith drill bit repeatedly More than 20 tests, basically realized the vacuum bit oiling. We do the test is two categories: The first category is a single test, the purpose is to ensure that equipment can
