Abstract

The invention provides an efficient airtightness faucet for an engineering driller. The faucet comprises a rotation core tube and a rotation shell body; bearings are respectively installed at the twoend heads of the rotation core tube, and the rotation shell body sleeves the rotation core tube; rotation seals are installed on the sides of the bearings, and bearing end covers are arranged on the other sides of the bearings; end cover seals are arranged in the bearing end covers and connected with the bearings, and soft steel base plates are arranged on the sides of the bearings and the bearingend covers; a gooseneck is arranged in the middle of the rotation shell body. Through the ingenious design of the structure, the performance requirements of good airtightness, work stability, safetyand reliability, long service life and quick and convenient replacement are met, the technical problems that the airtightness performance is poor, and a sealing piece can be easily damaged are solved,the faucet can met the technical requirement that the efficient airtightness is achieved in any severe environment, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a high-efficiency airtight faucet for engineering drilling rigs, which belongs to the technical field of engineering machinery and is suitable for providing working media for rotary drilling tools. Background technique [0002] Fengshui faucet is an important device connected to the driver to provide working medium for rotary drilling tools. According to the needs of engineering drilling rig research and development, it is necessary to develop a high and medium pressure sealed Fengshui faucet to provide working medium for rotary drilling tools. [0003] At present, the sealing performance of the existing structure of the Feng Shui faucet seal is poor and the sealing life is short. During the drilling work, the seal needs to be replaced frequently, so that the construction cost and working time are increased, resulting in high labor intensity and low work efficiency. Inconvenient to operate. Contents of the invention [0004]...
