Definitions

  • ABSTRACT The present invention relates to sealing of shafts of mining face engines.
  • the principal object of the invention is to eliminate the disadvantages of the known apparatus of this kind. To achieve this object it has a floating piston which com- [51] Int. 49/04, presses the face seal pair that opened under the effect ofvibra- F04b l/12 tion, thereby restoring normal functioning of the seal.
  • the object of the present invention is to create an arrangement to seal the shaft of mining face engines, which would permit sealing the rotating shafts at large pressure drops with a high degree of reliability in operation.
  • the plunger pump be driven by the shaft of the'drilling engine through a bevel washer.
  • a gauge pressure of the order of. 100 kg../crn. acting in space l is directly taken up by the hydraulically relieved end seal 2.
  • the oil leaking through this seal comes via channel 3 into chamber 4 separated from the low pressure space S by the second (additional) end seal 6, and an annular piston 7, space 8 above being through channel 9 connected to the low pressure space 5.
  • a plunger pump 10 which consists of plunger 11, spring 12, suction valve 13, and pressure valve 14.
  • the arrangement is enclosed outside by casing 17, and inside-by shaft 15.
  • annular piston 7 performs oscillatory movements during which pump 10 evacuates oil from chamber 4 to the high pressure space 1 or alternately works idly.
  • the constantly maintained low pressure drop at the second face seal 6 ensures stable operation of this seal with a minimum oil leakage to the low pressure space.
  • An arrangement for sealing the shaft of a drilling face engine comprising; a casing encompassing said shaft to form an annular space; a first face seal dividing said annular space into high and low pressure spaces; a second face seal being mounted in said annular space at the low pressure space side thereof so as to define a chamber between said first and second face seals; a plunger pump including a suction valve mounted in said chamber, said pump being adapted to pump oil leaking from said high pressure space into said chamber back to said high pressure space; and a floating piston being located in said chamber intermediate said pump and said first face seal, said floating piston being adapted to open the suction valve of said pump when pressure in said chamber drops and to press up said first seal when pressure in said chamber rises respective to the pressure in the low pressure space.
