Definitions

  • the present invention relates to a self-priming side channel pump particularly intended for pumping liquid gases, such as butane-propane mixtures, in buried tanks, in particular with a view to their distribution by gun to users.
  • liquid gases such as butane-propane mixtures
  • This pump with vertical axis for buried tanks of liquid gases comprising a pump body with impellers fixed on the motor shaft and a suction mechanism connected to the pump body comprising a suction flange, a centrifugal wheel, a non-return valve and a closing valve housed at the foot of a well and controlled against return springs, characterized in that the non-return valve integral with the suction flange of the centrifugal wheel can communicate with the contents of the tank by the shut-off valve and in that one or more drain valves housed in a ring of the suction flange, allowing the complete evacuation of the residual liquid gas contained in the pump body as well as between the check valve -return and the closing valve.
  • This vertical axis pump is intended to be housed in a well 1 fixed on a crown 2 bolted to the manhole provided at the top of the tank 3 so that it can be easily put in place or removed; the motor (not shown) is fixed to an external lantern 4.
  • the pump essentially comprises a high self-priming assembly 41 similar to that of known self-priming pumps with a horizontal axis situated below open-air tanks, that is to say that on the drive shaft 5 the finned wheels 40 and intermediate suction and delivery bodies are fixed.
  • This shaft is guided at its ends in bearings 7 and 8 and coupled at its free end to a shaft 14 which extends it vertically.
  • the self-priming top assembly 41 is fixed at the top and bottom on fixed flanges 6 carrying the bearings 7 and 8 of the shaft.
  • the bolted rods 9 secure the pump body to the crown 2.
  • the dispensing orifice 10 of the delivery flange 11 At the upper part of the top assembly 41 is provided the dispensing orifice 10 of the delivery flange 11.
  • the flange 17 is secured by bolted rods 19 with a suction flange 20 at the base of which is fixed a non-return valve constituted by a grid 21 serving as a support surface for a flexible membrane 22 and delimiting a space of suction 23 under the centrifugal wheel 31.
  • This flange 20 is integral with a crown 25 which encloses the grid 21 with the pump part.
  • This assembly can slide in a cylindrical sleeve 24 welded to the base of the tubular well 1.
  • This sleeve 24 has a square return 26 which serves as a seat for the closing valve 27, which, when it is open due to the stop of the fingers 30 against the crown 25 of the suction flange 20, allows communication between the pump and the tank and which, pushed by a return spring 28, is applied against the angle return 26 when the suction assembly slides upwards.
  • Seals 42 seal between the valve 27 and its seat 26 on the one hand and seals 44 seal between the outer face of the crown 25 and the machine 24 during the disengagement stroke of the pump.
  • the fingers 30 have a height such that the valve 27 remains open when it is pushed by the crown 25 and closes on its seat 26 when it is pushed back by the spring 28 when the pump is removed.
  • drain valves 32 each comprising a finger 33 whose upper end is capped by a flexible open membrane 34 and whose lower end is pushed elastically through the orifice 35 of a partition 36 of sleeve 24.
  • the low centrifugal assembly 16 comprising the centrifugal body, the centrifugal suction wheel 31 and the suction flange 20, rests on the seat formed by the angle return 26 of the sleeve 24; the valve 27 abuts with its fingers 30 against the crown 25 against the return spring 28 revealing the communication channels 43 between the pump and the tank.
  • valve 27 when the pump is removed, the valve 27 is closed, the non-return valve 21, 22 is closed, the drain valve 32 is open and the seal between pump body and well is ensured until valve 27 is completely closed by seals 44.
  • the non-return valve 21, 22 can be of any known type.
  • the invention resides in the adaptation under the central lower assembly 16 of a closing valve 27 controlling the communication between the contents of the tank 3 and the pump, this valve closing automatically when the pump is removed, d '' at least one drain valve 32 housed in the ring 25 and a sealing system between the closing valve 27 and its seat 26 on the one hand and between the periphery of the ring 25 secured to the suction flange 20 and the fixed sleeve 24 forming a valve seat on the other hand.
