Definitions

  • the present invention relates to a method of lubricating compressors, in particular of the helical type.
  • the quantity of oil necessary for this purpose is a function of the quantity of calories to be removed, since the temperature of the mixture of air and oil discharged from the compress must be within a well-defined temperature range, in order to avoid water condensation in the oil tank on the one hand, and auto-ignition of the air-oil mixture on the other.
  • the Demand therefore sought to reduce the quantity of oil when idling while reducing the power consumed at such a rate much more significantly than in conventional compressors, and this by implementing a simple secondary lubrication circuit and high reliability.
  • the object of the invention is therefore a lubrication process of a compressor for a fluid of the type comprising a compression chamber in which at least two rotors are rotated by at least one gear and each rotate on two end bearings, said bearings and gear being housed in flanges forming volute office, namely a suction flange and a discharge flange, said gear being linked to a driving shaft, the sealing of said shaft being ensured, suction side, by a friction grain seal, characterized in that, in operating speed under load, said compression chamber, said bearings, said gear, as well as said friction grain seal are supplied with oil coming from a separating tank and under a high pressure and substantially equal to that prevailing in said separating tank, while under idling conditions said compression chamber and said bearings housed in said delivery flange are supplied with oil from said tank s spacer but under low pressure, the bearings, said gear, as well as said friction grain seal housed in said suction flange being independently supplied with oil coming directly from the exhaust or
  • the invention also relates to a device for implementing the method according to claim 1, characterized in that it comprises two circuits, a main circuit and a secondary circuit, said main circuit comprising a pipe having its source in said separator tank of oil and subdivided into three branches, a first branch supplying said compression chamber, a second branch supplying said bearings, said gear and said friction grain seal housed in said suction flange via a valve, and a third branch supplying said bearings housed in said delivery flange, said secondary circuit comprising a pipe originating directly from the compressor exhaust, leading to a valve, then subdivided into two branches, a first branch supplying the bearings and the gear housed in said suction flange, by through a valve, and a second bypass supplying the friction grain seal.
  • the compressor lubricated in the known manner and represented in FIG. 1 therefore comprises a compression block 1 in which two helical rotors rotate, a male rotor 2 and a female rotor 3, the male rotor 2 being driven by means of a motor 4 and by by means of a gear 5 cooperating with a universal joint 6, housings such as 7 ensuring sealing.
  • This pipe 9 opens into an oil separator tank 10 above, of course, the oil level 11.
  • the compressed air is therefore evacuated to the place of use via the line 12 according to the arrows, after having abandoned the entrained oil particles at the level of a filter 13.
  • the suction 8 is therefore partially obstructed in order to reduce the pressure in the separator tank 10 and consequently the compression power.
  • the Applicant has therefore sought to remedy such a drawback and to significantly reduce the power consumed when idling, and this by implementing a simple, inexpensive and reliable additional lubrication circuit.
  • the compressor shown in FIG. 2 comprises a casing 20 or compression block inside which two rotors move in rotation, a male rotor 21 and a female rotor 22 of helical type. These rotors rotate on ball or roller bearings, namely bearings 23 and 24 for the male rotor 21 and bearings 25 and 26 for the female rotor 22.
  • Such bearings are housed in flanges 27 and 28, the flange 27 acting as a suction scroll, while the flange 28 assumes the role of discharge or exhaust scroll.
  • the male rotor 21 has a shaft end (not shown) on which is keyed a multiplier gear train 29 linked to a driving shaft 30 journalled on bearings 31 and 32, the seal being ensured by means of a seal grain rubbing 33.
  • two lubrication circuits are used, a main circuit and a secondary or additional circuit.
  • This bypass 40b can be opened or closed by a valve V2.
  • a third branch 40c supplying the bearings 24 and 26 via a conduit 42.
  • a second bypass 43b supplying the friction seal 33 as well as the bearing 32.
  • the pressure drops in said branches are predetermined so that the oil flow is sufficient.
  • the valve V2 is closed, but the oil still feeds the compression chamber 20, as well as the various organs on the discharge side by the branches 40a and 40c according, obviously, to a low flow rate, however sufficient.
  • the secondary lubrication circuit has a high cor..ductance, taking into account the relatively low pressure prevailing at point B.
  • valves V1 and V3 close, the valve V2 opens and so on.
  • the no-load power is divided by a coefficient at least equal to 2.5.
