Definitions

  • the present invention relates to a device for introducing air into a hydropneumatic reservoir equipping a hydraulic pipeline which may be, in particular, a drinking water or irrigation distribution network, or a sewage disposal network or of chemical liquids.
  • a hyropneumatic tank can operate as a regulating tank (or hydrophore) to regulate the pumping pressure and ensure continuity of service in the pipeline, in a pressure range between a high level and a low level.
  • a regulating tank or hydrophore
  • the pump or one of the pumps feeding the pipeline is stopped.
  • the regulating tank then makes a supply of water in the pipe.
  • the pump is restarted to ensure sufficient pressure and flow in the pipeline.
  • a hydropneumatic reservoir can also be used as a surge tank for a hydraulic pipeline to compensate for the effects of depression and overpressure caused by, for example, stopping a pump or closing a valve.
  • the operation of such a tank is known in particular by the French Patent No. 2,416,417 (ROCK).
  • EP 0 617 227 also describes an air regulation system for a hydropneumatic reservoir.
  • hydro-pneumatic tank requires the maintenance of a quantity of air as constant as possible inside it.
  • the hydropneumatic reservoir indeed contains, in operation, water or any liquid flowing in the pipe, and air enclosed in the tank just above the surface of water or liquid. A dissolution of the air in the liquid can occur and thus create a variation in the amount of air trapped in the tank. It is therefore necessary to introduce air into the tank in case of insufficiency.
  • bladders which have drawbacks of cost or even of fragility, especially for large installations and high pressures, loss of pressure at the drain due to the establishment of a grid designed to prevent bladder extrusion, and need to control the air inflation of the apparatus.
  • air compressors are not recommended for drinking water systems because of the risk of oil in the injected air, and are relatively expensive.
  • the invention aims to overcome the disadvantages of the above systems by providing a simple air introduction device, inexpensive, low energy consumption and does not change the hydraulic operation of the installation.
  • the air introduction device is intended for a hydraulic system comprising a hydropneumatic reservoir mounted on a pipe.
  • the air introduction device is mounted to introduce air into a water zone of the system where the pressure is close to atmospheric pressure, that is to say lower or slightly higher.
  • the device is active only when a lack of air is found in the hydro-pneumatic reservoir. Thus, the energy required by the introduction of air is low, or almost zero in some cases.
  • the device comprises, in general, an air supply tube equipped with means for controlling the introduction of air.
  • the air introduction device is mounted on the pipe between a water intake and a pump.
  • the pipe is provided with a depressive means upstream of the hydro-pneumatic reservoir, the air supply tube being connected to said depressor means.
  • the air introduction device comprises a bypass tube connected to a water portion of the hydropneumatic reservoir, an auxiliary pump mounted on the bypass tube, and a depressor means mounted in downstream of the auxiliary pump, the air supply tube being connected to said depressor means.
  • the depressive means comprises a venturi tube.
  • the venturi tube makes it possible to obtain a liquid pressure that is locally lower than the atmospheric pressure.
  • Other means of depression can be envisaged: diaphragm, etc.
  • the air introduction device comprises an electric valve and a control valve or an air flow rate limiter disposed on the air supply tube.
  • the air introduction device is mounted upstream of a pump, the air supply tube opening into the low pressure zone of the pump.
  • the zone of low pressure designates the place of the pump where, during its operation, air can be injected and where the pressure of the liquid nets is minimal or close to the minimum.
  • the air supply tube may open into the inlet strainer of the pump.
  • the air introduction device comprises a small air booster mounted on the air supply tube, when the pressure P S is greater than the atmospheric pressure.
  • P S is the absolute pressure in the air introduction zone, pump strainer, low pressure zone of the pump, suction line upstream of the pump, etc.
  • the pressure P S is below atmospheric pressure and the booster is unnecessary.
  • the invention also relates to a pump equipped with an air introduction device and a hydropneumatic reservoir equipped with an air introduction device.
  • the hydraulic system comprises a pipe 1 provided with a pump 2 and a hydropneumatic reservoir 3 disposed downstream of the pump 2 on the pipe 1 and serving as a regulating tank or anti-tank ram.
  • the upstream end 1a of the pipe 1 is equipped with a strainer 4 and a foot valve, not shown, for taking water or any liquid in a tank 5.
  • the hydropneumatic reservoir 3 allows to adjust the flow of liquid in the pipe 1 to the needs of users.
  • the pump 2 is stopped and the hydropneumatic reservoir 3 is gradually emptied by supplying liquid in the pipe 1.
  • the pump 2 is restarted to ensure, on the one hand, the flow in the pipe 1 and, on the other hand, the filling of the hydropneumatic reservoir 3.
  • Another use of the hydropneumatic reservoir is the use as an anti-ram reservoir as already indicated.
  • the proper operation of the hydro-pneumatic reservoir 3 requires a relatively constant amount of air to be present inside. However, the air present in the hydro-pneumatic reservoir 3 tends to dissolve in the liquid.
  • an air introducing device 7 comprising a tube 8, one end of which opens into the open air and the other end of which opens into the pipe 1.
  • the electric valve 9 is connected to a air loss detector 11 disposed on the hydropneumatic reservoir 3.
  • the air loss detector may be, for example, a level sensor but other systems are possible.
  • the electric valve 9 Only when a lack of air is to be filled in the hydropneumatic reservoir 3 and the pump 2 is in operation, the electric valve 9 is open, which causes the introduction of air through the tube 8 into the pipe 1 in upstream of the pump 2. Indeed, the pressure P S prevailing in the portion of pipe 1 limited by the pump 2 and the strainer 4, is lower than the atmospheric pressure due to the suction of the pump 2 and the fact that it is disposed above the level of the body of water. The air thus introduced then passes into the pump 2 and then into the hydropneumatic reservoir 3.
  • an air trap 12 can be provided. disposed at the base of the hydropneumatic reservoir 3.
  • the air trap 12 may consist of a downwardly sloped pipe portion in the downstream direction.
  • the tank 5 is disposed at an altitude higher than that of the pump 2.
  • the air introduction device 7 is then placed in the immediate vicinity of the pump 2, the air supply pipe 8 opening into the zone low pressure of the pump 2 to take advantage of the fact that the pressure P S y is lower than the atmospheric pressure.
  • the pump 2 is of the submerged type.
  • the air introduction device 7 is again provided with the tube 8 opening into the low pressure zone of the pump 2 to take advantage of the fact that the pressure P S y is lower than the atmospheric pressure.
  • the air introduction device operates in the same way for a pump or for a plurality of pumps arranged in parallel. Only one device can be provided for several pumps, the tube 8 then comprising ramifications towards each pump after the electric valve 9 and the control valve 10 ( Figures 1, 2, 3 ), or each equipped with an electric valve to prevent pressurized air from reaching the strainers of the pumps at standstill ( figures 4 and 5 and possibly 6).
  • the air supply tube 8 of the air introduction device 7 opens into the strainer 4 of the pump 2.
  • the pressure P S prevailing in the strainer 4 is slightly greater than the atmospheric pressure.
  • the air introduction device 7 is therefore provided with an air booster 13 arranged upstream of the control valve 10 and capable of providing a slight overpressure with respect to the pressure P S prevailing in the strainer 4 minus the pressure atmospheric pressure and the pressure drops in the device. For example, an overpressure of the order of a few tenths of bars may be necessary.
  • the figure 5 shows a variant close to the figure 4 , in which the pump 2 is replaced by a pump unit immersed provided with a pump 14 and a drive motor 15.
  • the electric valve is not necessary because the introduction of air is controlled by the operation and stop of the booster 13.
  • the booster 13 works only when it is necessary to compensate for an air deficit in the air. hydro-pneumatic tank and when the pump is running. It is possible to equip the air supply tube 8 with a valve 16.
  • the figure 6 shows a hydraulic system identical to that of the figure 2 but in which the air introduction device is similar to that of the figure 4 because P S is greater than the atmospheric pressure.
  • the air introduction device is provided with a booster 13 and its tube 8 opens immediately at the inlet of the pump 2 or, which is better, in the low pressure zone of the pump 2, which reduces the value of P S.
  • the booster 13 may be equipped with a buffer bottle, not shown, in case its flow rate is too great.
  • the valve 16 or an electric valve 9 is here essential to prevent a return of liquid to the booster 6, when the pump 2 is stopped and the booster.
  • the air introduction device 7 is provided with a submerged booster 13, the control valve 10 being disposed in the open air, upstream of the booster 13 on the air supply tube 8.
  • the tube 8 is connected to a strainer or to the low pressure zone of a submerged pump, not shown.
  • the hydropneumatic reservoir 3 is disposed in an extended position and is connected to an upstream pipe portion 1b and to a downstream pipe portion 1c.
  • the two pipe portions 1b and 1c open directly into the hydro-pneumatic reservoir 3 without being interconnected, it is ensured that air arriving through the upstream pipe portion 1b remains in the hydropneumatic reservoir 3 and is not sent in the downstream pipe portion 1c.
  • An equivalent system can equip a hydro-pneumatic reservoir in a vertical position, the pipe portions 1b and 1c then arriving in the convex bottom of this tank.
  • a venturi tube 17 which is in the form of a necking, is disposed on the pipe 1.
  • the venturi tube 17 comprises a convergent 17a, a cylindrical portion 17b and a divergent 17c.
  • the operating pressure P S in the cylindrical portion 17b is much lower than the pressure prevailing in the remainder of the pipe 1.
  • the venturi tube 17 is dimensioned so that the pressure P S is less than atmospheric pressure.
  • the air introduction device 7 comprises an air supply tube 8 in communication with the cylindrical portion 17b, an electric valve 9 and a control valve 10. It is thus possible to introduce air into a pipe . under high pressure when the electric valve 9 is open.
  • the invention there is a device for introducing air into a hydropneumatic reservoir adapted to hydraulic systems of various types, anti-ram balloons, regulating tanks, low cost and low energy consumption. .
