- 1 METHOD OF PRIMING A FILTER PUMP OF A SYSTEM FILLED WITH WATER AND PRIMING CONNECTION FOR

THE IMPLEMENTATION OF THE PROCESS

The field of the invention is essentially that of swimming pools.

A swimming pool is a basin which is associated with a technical room in which there is mainly a filtration pump, associated with a filter, generally with sand or cartridge, through which the water of the basin continuously flows after it has been filled, precisely to filter this water permanently. The basin is connected to the pump by several suction pipes and a discharge pipe. Generally still, to a filtration pump are connected suction pipes connected, respectively, to a bottom drain, to “skimmers”, to a socket for manual broom.

When you put the pool out of service, in full wintering, so when you have drained all the water from the technical room, you stop the pump - which can be at a level higher than that of the surface of the pool water - and the water in the pump and at least in the adjacent portion of the suction pipes flows into the basin, in any case, towards the basin.

When the swimming pool is put back into service, you must prime the filtration pump. To do this, open the pump by removing its top cover, inject water into the pump from above, which should descend by gravity into the filtration pipes connected at the bottom of the pump, close the pump and the pump is started. It is also possible to inject water through the pump pre-filter.

But a problem frequently arises.

Indeed, a suction pipe may have been improperly installed, with elevation differences, elbows and other cant, to the point that air pockets

B E2017 / 5511

- 2 are there, so that the pump does not manage to suck up the water, with the risk, without betting on the flooding of the room, that the pump undergoes a destructive heating. Even admitting that, by repeating the priming steps, we end up priming the pump, priming only takes place after a much too long time.

It will be noted that this problem of re-priming a filtration pump can just as easily arise during the first priming of a new pump.

It will also be noted that the same problem can also arise in an automatic watering installation which includes a booster, very similar to a swimming pool filtration pump, but without a pre-filtration device.

The invention of the present application therefore aims to solve the problem presented above and therefore relates to a method of priming a filtration pump of an installation filled with water, connected to the installation by at least one pipe. suction and a water discharge line in the installation, the pump comprising a suction inlet port, a discharge outlet port, a purge outlet port at the bottom of the pump and a inlet port for priming water injection in the upper part, process characterized in that:

- the pump priming water injection inlet port being closed and the pump stopped,

- the purge outlet port is opened,

- water is injected into the pump through the purge outlet port and

- the pump is started,

- the boosting of the pump and of the suction pipe ensuring, after evacuation of possible air pockets in the water of the installation, priming of the pump.

B E2017 / 5511

- 3 Note that (the priming process may only be implemented after emptying the installation of its water.

Naturally, after priming, the injection of water is stopped by the purge outlet port which is closed, while leaving the pump in operation.

If air is drawn into the pump during these last operations, it is too small to prime the pump.

Thanks to the process of the invention, any risk of overheating of the pump or deterioration of equipment is avoided. The priming is carried out without constraint, effort and with ease.

If the installation comprises several suction pipes, either they do not have a shut-off valve, and, then, the priming process is implemented simultaneously with all the pipes, or the pipes have a shut-off valve and, then, one proceeds to the method of priming pipe by pipe with its shutter valve open, the other valves being in the shutter position.

If the discharge line can be blocked, it is closed before opening the purge outlet port and the valve is released before restarting the pump, which allows a much faster feeding.

The priming process can therefore be applied to a swimming pool filtration pump, which is connected to a basin filled with water, the discharge pipe being intended to discharge the water into the basin.

The priming process can also be applied to an automatic sprinkler installation, the filtration pump being qualified as a booster then without a pre-filtration device and the reB E2017 / 5511 pipe.

- 4 bearings being intended to discharge water into pipes and sprinkler nozzles of the installation.

The invention also relates, as an intermediate product which could be supplied for the implementation of the method of the invention, and therefore proceeding as such from the same inventive concept, a priming connection c

comprising an inlet port, arranged to be connected to a garden hose, and an outlet port, arranged to be connected to a purge outlet port of a filtration pump of a group water installation comprising a swimming pool and a sprinkler system, for implementing the method of the invention.

The filtration pump purge outlets generally comprising a tapped port closed by a threaded plug and the garden hoses generally comprising a lance connected to the hose by two so-called male and female quick couplings, respectively, the connector of the invention com15 carries a male threaded output port and a male quick connect input port.

The term quick connection is understood to mean a connection by means of two male and female connectors arranged to cooperate by snap-fastening or clipping or bayonet cooperation.

Preferably, the connector of the invention comprises, between the two inlet and outlet ports, a movable closure means, of the quarter-turn rotary type.

The invention will be better understood on reading the following description made with reference to the appended drawing, in which:

- Figure 1 is a sectional view of a swimming pool with the main equipment of its technical room and the pipes connecting the basin to these equipment;

B E2017 / 5511

- 5 - Figure 2 is a view of a swimming pool filtration pump, with its various suction pipes;

FIG. 3 is a side view of a connector for implementing the method of the invention and

FIG. 4 is a side view of a filtration pump on which the connector of FIG. 3 is mounted,

The swimming pool in Figure 1 has a basin 1, filled with water, with a port 2 for filling, better discharge, a bottom drain 3, for sucking water or emptying the basin, skimmers - only one 4 is visible in the figure - to draw water from the surface, and a socket 5 for the manual broom, for cleaning the bottom and walls of the basin 1.

The water in the pool, when the pool is running, flows from pool 1 to a filter 6, here a sand filter, via a filtration pump 7, and from filter 6 to the pool 1.

The bottom drain 3, the skimmers 4 and the brush outlet 5 are respectively connected to the pump 7 by three suction pipes 8, 9, 10 united in a single pipe 11 upstream of the pump 7.

Upstream of the suction pipe 11 connected to the pump 7, shut-off or stop valves 12, 13 are mounted on the suction pipes 8, 9 of the bottom drain 3 and of the skimmers 4 .

Between the filtration pump 7 and the filter 6 is mounted a multi-way valve 14 connected to the pump 7 by a discharge line 15, to the filter 6, by two water inlet pipes to be filtered 16 and water outlet filtered 17, in the basin 1, by another discharge line 18 and, here, in the sewer 50 by a line 51.

B E2017 / 5511

- 6 The filtration pump 7 installed here comprises an inlet pump body 19, with a suction inlet port 20, and an outlet pump body 21, with a discharge outlet port 22.

The pump impeller, not visible in the drawing, can be rotated by a motor 23. The inlet pump body 19 in FIG. 4 has, at the top, an upper cover 24 which, when removed, clears an opening qualified here as an inlet port 25 for priming water injection, through which operators used to inject water to prime the pump after a period of non-operation. The inlet pump body 19 of the filtration pump 7 also comprises, at the bottom, an orifice, or outlet port, for purging 26 which, in operation, is closed by a plug.

The priming of the pump 7 is carried out by a process which makes use of a particular priming fitting 27 (FIG. 3). The connector 27 comprises a male inlet nozzle 28, designated here by the inlet port, which can be connected to a garden hose. The most available garden hoses on the market have a lance generally mounted on the hose via a so-called quick coupling. This is why, the inlet end piece of the connector 27 is shaped so as to be able to cooperate with a quick coupling of the garden hose and therefore therefore includes an annular peripheral groove 29, for receiving snap lugs provided on the integral connection of a garden hose.

The connector 27 also includes a male outlet end piece 30, designated here as the outlet port, which, in this case, is threaded so that it can be screwed into the female bleed outlet port 26 of the pump 7 which is located here. tapped.

B Ε2017 / 5511

-Ί The two end pieces 28, 30 of the connector 27, of generally tubular shape, are here coaxial and a shutter butterfly 31 is disposed inside the connector between the two end pieces, operable by means of an external valve. 32. The papifion 31 is mounted here rotary on a quarter turn.

The initiation process of the invention will now be able to be described.

Filtering pump 7 has been switched off for some time and drained of water, and thus before the reboot, and the bung ¹⁰ base 3 located in the basin, which is then drained of water by, the stop valve 13 of the skimmers 4 and the multi-way valve 14 and therefore also the discharge outlet port 22 of the pump are closed, while leaving the cover 24 in the closed position.

¹⁵ Note that if the bottom drain 3 had not been in the basin, it would have been necessary to close the valve 12 and leave the stop valve 13 of the skimmers open, while ensuring that the water level is three-quarters in the skimmers 4 and therefore start priming with the suction line 9 of the skimmers.

The filtration pump still being stopped, the purge plug of the pump is removed to open its purge outlet port 26. The connector 27 is screwed into the purge outlet port 26 by its outlet nozzle 30, with interposition of an O-ring 33 (Figure 3). The rac25 cord 27 is connected to a garden hose by its inlet nozzle 29.

Through the garden hose and the priming connector 27, water is injected into the inlet pump body 19 through the purge outlet port 26, it is expected that the pipes 11, 8 are filled with water and the multi-way valve 14 is opened. The pump is started. Optionally, you may want to stop the pump 7 for a few moments so that the pipes E2017 / 5511

- 8 tions 11, 8 fill with water and restart the pump again and this, several times in burst until the priming of the pump. The boosting of the pump and of the suction pipes 11, 8 pushes back any air pockets in the basin 1, which can be seen, and it ensures the priming of the pump. Of course, after priming the pump 7, the connector 27 is closed using the lever 32, the garden hose is removed and, leaving the pump running, the connector 27 is unscrewed from the pump and it is filled in. purge 26 by its plug. The air that could be sucked in then is not enough to defuse the pump.

The method of the invention offers the advantage of considerably accelerating the priming time, from five to ten times faster than traditional priming. For example, for a filtration pump 5 m away from the pool and simple filtration, priming can be carried out in 30 to 60 s; for a complex installation and a technical room far from the basin, it is necessary to count, according to the method of the invention, to be able to prime the pump in 15 to 30 minutes, against 45 to 60 minutes according to the traditional method.

In certain installations, the filtration pump can be connected to several suction pipes on which stop valves are mounted. With reference to FIG. 2, in which the elements similar to those of FIG. 1 are associated with the same reference numbers, the filtration pump 7 is connected to the suction pipe 8 for bottom drain suction, with interposition of the valve. 12, to the suction line 9 of the skimmers, with the interposition of (a valve 13, and to the line 10 of the brush connection, with the interposition of a stop valve 40. It will be noted that at the outlet of the valve multichannel 14, a bromine / chlorine metering device 42 is mounted in parallel on a stop valve 41 mounted on the discharge pipe 18 and that the pump 7 is controlled by an electrical filtration cabinet 43.

In the case of the assembly of FIG. 2, for priming the pump, the suction pipe is carried out by suction pipe. So,

- 9 starting with the suction pipe 8 of the bottom drain 3, the suction valves 13, 40 are closed and the valve 12 is slowly opened.

After having, so to speak, purge the pipe 8, the valve is closed and the valve 40 is kept closed, and the valve on the skimmers pipe is slowly opened. Then we proceed with the line 10 of the brush outlet, closing the valves 12, 13 and slowly opening the valve 40.
