The reversed resistance of sharf, while air discharge duct is biased to outgassing groove setting along eccentric orfice inner wall relative to air inlet duct, so that air cavity is let out
Pressure lag, sharf output torque increase, and effectively improve transmission efficiency and output torque.
Working principle is as follows:
When buried pipe says existing breakage, which is put into underground piping, whirl spraying is then drawn by wirerope
Repair apparatus slides into breakage, and then pressure-air enters air inlet duct from air inlet, and then enters eccentric orfice inner wall, sharf
The air cavity formed between outer circle, drive end bearing bracket, rear end cap 18 and blade, driving blade rotation, and then sharf rotation is driven, when this
Air cavity becomes larger, and carries out pressure release when turning to pressure-air discharge at air discharge duct, which continues to rotate to outgassing groove direction,
Under the air cavity gradually becomes at this time, remaining air is gradually compressed in air cavity, and the pressure release at outgassing groove, reduces turning for sharf
Dynamic resistance, sharf drive discharge head rotation, and repair paint enters discharge head inner cavity by feed pipe, and discharge head rotate from
Under the action of mental and physical efforts, by even application on underground piping inner wall, wanted when the repair paint thickness on underground piping inner wall reaches
When asking, wirerope draw whirl spraying repair apparatus along underground piping move axially, complete the spraying of breakage, the repair paint thickness compared with
It is small not influence the unobstructed of underground piping, while intensity is greater than underground piping.
The above is only the preferred embodiment of the present invention, are not intended to restrict the invention, it is noted that this technology is led
For the those of ordinary skill in domain, without departing from the technical principles of the invention, several improvements and modifications can also be made,
These improvements and modifications also should be regarded as protection scope of the present invention.
