Definitions
- the present invention relates to a self-priming side channel pump particularly intended for pumping liquid gases, such as butane-propane mixtures, in these buried tanks, in particular with a view to their distribution by gun to users.
- liquid gases such as butane-propane mixtures
- this pump comprises two main parts, a pump with a battery of impeller wheels of a conventional type but with a vertical axis, high and low flanges for assembling the pump by bolted lateral rods, a distributor flange with the upper part and a fixing of this assembly on a vertical well fixed at the periphery of a manhole at the upper part of the tank.
- the motor shaft driven by a motor mounted on an external lantern is sleeved at its base with a shaft actuating the centrifugal impeller of a second part of the pump.
- This second part comprises a pump connection tube with a body constituted by a suction flange, by the centrifugal wheel, a crown fixed to the base of this flange, a support flange being bolted to the base of the connection tube and connected by tie rods to the crown.
- This crown is used for fixing an anti-siphoning valve and housing at least one purge valve.
- a sleeve with an inward angle return which serves as a seat for a shut-off valve arranged below the siphon valve and near the bottom of the well; this valve is normally moved away from the valve to allow free communication between the tank and the pump, but it is subjected to the action of springs to apply on its seat and cut the communication if the pump is removed, for example for its maintenance.
- the locking valve In normal service, the locking valve is open, being in abutment against the suction flange of the centrifugal wheel; if the pump is removed, it gradually closes to let the purge valve empty the pump of its contents.
- Seals O-rings for example, are provided on this valve to complete the seal.
- Other seals are also provided on the external wall of the crown fixed to the base of the suction flange which is in rubbing contact with the sleeve; the displacement stroke of this ring corresponds to the clearance of the valve between its open and closed positions.
- the pump motor starts and drives the shaft on which its wedged the impeller wheels of the pump and the centrifugal wheel of the suction flange , the valve of the liquid suction chamber is open as well as the valve which controls the communication openings of the pump with the tank; the drain valves are closed.
- the membrane of the suction valve closes on its support grid, the drain valves open, thus emptying the liquid contained in the pump and the valve for communicating the pump with the tank is pushed elastically back onto its seat, interrupting all communication of the contents of the tank with the well and preventing any infiltration thanks to the seals.
- 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 housed in an external lantern 4.
- the pump essentially comprises an upper part which is 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 are wedged the fins 40 and an intermediate delivery body 11.
- 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 pump body 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 35 At the upper part of the pump body 41 is provided the dispensing orifice 10 of the delivery flange 35.
- an assembly comprising a connecting tube 12 of a height such that it is flush with the base of the tank 3. and which supports the flange 17, the centrifugal wheel 31 and the anti-siphon valve 21; the lower end of the shaft 14 is mounted in a bearing 15 of the extension of the flange 17 secured to the base of the tube 12.
- This assembly receives the centrifugal suction wheel 31 driven by the shaft 14.
- the flange 17 is secured by bolted rods 19 with a cylindrical suction flange 20 at the base of which is fixed a grid 21 serving as a support surface for a flexible membrane 22 forming a suction space 23 under the centrifugal wheel 31
- This flange 20 is integral with a crown 25 which encloses the grid 21 with the pump.
- This assembly can slide in a cylindrical sleeve 24 welded to the base of the tubular well 1 of the pump.
- This sleeve 24 has a square return 26 which serves as a stop for a concave plane 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 the communication of the pump and the tank and which, pushed by springs 28, is applied against the angle return 26 when the suction assembly slides upwards.
- O-rings 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 sleeve 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 springs 28 when the pump is removed.
- drain valves 32 each comprising a finger 33 whose upper end is capped by a flexible split membrane 34 and whose lower end is pushed elastically towards the orifice 35 of a partition 36 against the sleeve 24.
- valve 27 when the pump is removed, the valve 27 is closed, the valve 22 is closed, the drain valve 32 is open and the seal between pump body and well is ensured until the complete closure of the valve 27.
- the anti-siphoning valve can be of any known type.
- the invention lies in the adaptation to the flange of a control valve for communication of the contents of the tank and of the pump which closes automatically when the pump is removed, at least one drain valve housed in the suction flange and seals between the closing valve and its seat on the one hand and between the side of the suction flange and the fixed sleeve forming the valve seat on the other hand.
