Description
Technical field
The present invention relates to the flushing liquid sealing device in rock borer.The invention still further relates to method, flushing housing and the rock borer for this device, produced.
Background technology
Previously known has the rock borer of the drill string that impacts and rotate, and drill string band is useful on the liquid wash that removes the well drilling detritus forming during boring.This rock borer is provided with built-in flushing liquid rotary body (swivel) in the region of the drill string guiding device of for example rock borer.In this fluid body rotary body, the bit shank of rock borer (shank adapter) is provided with one or more radial hole, described one or more radial hole enters into the axial flushing hole of drill string for the flush fluid making into, this transfers to flow out drill bit.The rotary body of previously known is arranged on the either side of the opening that is included in described radial hole and is fixed on the liquid sealant in rock borer.
As flush fluid, conventionally use the local water obtaining at boring sites in curing place, described water is substantially only separated with solid particle essence and be pumped into immediately rock borer, further to transmit downwards through the flushing hole in drill string.Because this water can comprise a high proportion of salt, therefore normally deep-etching of this water, thus cause the risk to the exposed component corrosion of rock borer.Therefore, on the sealing surfaces of bit shank, occur corrosion-damaged, described sealing device with sealing surface against contacting.This has caused the shortening in the application life of sealing device; Especially because the corrosion impact surface part on bit shank is passed through the promptly sealing surfaces of abrasion sealing device of its surface roughness.Especially, after machine down, sealing device easily suffers damage when restarting due to the described corrosiveness on bit shank.
Other problem is the risk to the grievous injury of bit shank, and especially in the region of described radially flushing hole, due to what occur, corrosion-damagedly can cause causing fatigue fracture.The generation of this fracture can cause rock borer grievous injury and cause the withholding period of rock borer.
The example of technology can be mentioned in WO03078788 as a setting, and WO03078788 discloses a kind of erosion-resisting method of corrosion susceptibility parts making in rock drill, and wherein, bit shank covers with special protectiveness compound.
