Abstract

The pressurising pump consists of a body (6) defining a chamber (7) in which moves axially, a piston (8) connected to a rod (9) whose movement is controlled by a motor. Inlet to the pump of the fluid is via the portion (10) and outlet is via the porting (11) from whence it is fed to an applicator (3). The pump is characterised in that its external face (14) is enclosed in a jacket (16) which forms a space (18) between this face (14) and the inner wall (17) of the jacket (16). The jacket is fixed in a removable fashion at the points (15). A fluid can circulate in this space (18) via connection pieces (20). <IMAGE>

Description

L'invention se rapporte a une pompe pour la projection sous pression d'un produit de marquage.The invention relates to a pump for the spraying under pressure of a marking product.

L'invention trouve son application notamment dans le domaine du marquage routier.The invention finds its application in particular in the field of road marking.

Pour le marquage routier, on utilise une installation comprenant :

  • un réservoir pour le produit à projeter,
  • un dispositif applicateur,
  • un circuit principal comprenant au moins une pompe qui, prélevant le produit stocké dans le réservoir, amène celui-ci au dispositif applicateur avec une pression prédéterminée.
For road marking, an installation is used comprising:
  • a reservoir for the product to be sprayed,
  • an applicator device,
  • a main circuit comprising at least one pump which, taking the product stored in the reservoir, brings the latter to the applicator device with a predetermined pressure.

Ces installations sont couramment appelées "AIRLESS" car le produit est projeté sans l'aide d'un gaz.These installations are commonly called "AIRLESS" because the product is sprayed without the help of a gas.

Classiquement, quel que soit le type de pompe utilisée pour ces applications routières, chaque pompe comprend :

  • un corps délimitant une chambre dans laquelle se déplace axialement un piston dont le déplacement est provoqué par le déplacement d'une tige reliée à un moteur tel un moteur hydraulique,
  • des moyens de contrôle dit d'entrée pour le passage d'un liquide depuis un circuit d'alimentation vers la chambre principale et
  • des moyens de contrôle dit de sortie pour le passage du liquide depuis la chambre principale vers un circuit alimentant un dispositif applicateur tel au moins une buse de pulvérisation.
Conventionally, whatever the type of pump used for these road applications, each pump includes:
  • a body delimiting a chamber in which a piston moves axially, the displacement of which is caused by the displacement of a rod connected to a motor such as a hydraulic motor,
  • said input control means for the passage of a liquid from a supply circuit to the main chamber and
  • so-called output control means for the passage of the liquid from the main chamber to a circuit supplying an applicator device such as at least one spray nozzle.

Pour le marquage routier, on utilise à ce jour deux types de produit de marquage.For road marking, two types of marking product are used today.

Les produits du premier type sont dits "à froid" car ils peuvent être appliqués à la température ambiante tandis que les seconds dits "à chaud" doivent être appliqués à une température supérieure à la température ambiante, c'est par exemple le cas des peintures thermofusibles ou des bitumes.The products of the first type are called "cold" because they can be applied at room temperature while the second so-called "hot" must be applied at a temperature above room temperature, this is for example the case of paints hot-melt or bitumen.

Les produits projetés à froid sont moins coûteux que les produits à appliquer à chaud mais, en contrepartie, pour leur durcissement, il faut attendre plus longtemps et donc neutraliser les voies de circulation pendant une durée non négligeable.Products sprayed cold are less expensive than products to be applied hot but, in return, for their hardening, it is necessary to wait longer and therefore neutralize the traffic lanes for a significant period.

Il faut donc faire un choix en fonction de chaque cas de marquage.A choice must therefore be made according to each marking case.

Les produits dits à chaud sont toutefois de plus en plus utilisés mais il n'est pas possible d'être certain de la continuité et de la rapidité de cette évolution.The so-called hot products are however increasingly used but it is not possible to be certain of the continuity and the speed of this evolution.

L'inconvénient est bien sûr que les matériels et notamment les pompes connus à ce jour pour la projection des produits à chaud doivent comporter des moyens de réchauffage qui en augmentent le coût.The disadvantage is of course that the equipment and in particular the pumps known to date for the projection of hot products must include heating means which increase the cost.

Ainsi, dans le cas d'installation pour projeter des produits à chaud, pour assurer le réchauffage de la pompe, l'installation comprend des moyens de réchauffage des éléments de l'installation et, à cet effet, le corps de la pompe loge une chambre annulaire entourant la chambre principale et dans laquelle chambre annulaire circule le liquide de réchauffement pour éviter le durcissement du liquide à projeter dans le corps de la pompe.Thus, in the case of an installation for projecting hot products, to ensure the heating of the pump, the installation comprises means for heating the elements of the installation and, for this purpose, the pump body houses a annular chamber surrounding the main chamber and in which annular chamber circulates the heating liquid to prevent hardening of the liquid to be projected into the body of the pump.

Les entreprises qui effectuent ces travaux de marquage doivent donc disposer de machines distinctes, chacune spécifique à un produit.The companies that carry out this marking work must therefore have separate machines, each specific to a product.

Pour répondre ponctuellement à des augmentations de charge de travail, pour l'application soit des produits à chaud soit des produits à froid, l'entreprise doit parfois être suréquipée en un type de machines voire les deux types.To respond punctually to increases in workload, for the application of either hot products or cold products, the company must sometimes be over-equipped with one type of machine or both.

Après l'achat d'une certaines quantité de pompe pour produits à froid, les entreprises risquent que le marché évolue vers les produits à chaud ce qui nécessiterait un nouvel investissement pour acquérir des pompes de l'autre type.After purchasing a certain quantity of pump for cold products, companies risk that the market will evolve towards hot products which would require a new investment to acquire pumps of the other type.

Pour limiter ce risque, il est possible de n'acheter que des pompes pour produits à chaud et de les utiliser aussi pour des produits à froid sans faire fonctionner le circuit de réchauffage mais, en raison de la différence de coût de ces pompes, l'investissement est beaucoup plus lourd.To limit this risk, it is possible to buy only pumps for hot products and also use them for cold products without operating the heating circuit but, due to the difference in cost of these pumps, the investment is much heavier.

Un des résultat que l'invention vise à obtenir est une pompe du type cité plus haut qui remédie aux inconvénients ci-dessus cités.One of the results which the invention aims to obtain is a pump of the type mentioned above which overcomes the drawbacks mentioned above.

A cet effet, l'invention a pour objet une telle pompe notamment caractérisée en ce que :

  • d'une part, autour de sa face externe, le corps de la pompe présente des moyens de fixation amovible d'une chemise apte à ceinturer le corps de la pompe en réservant entre la face externe du corps de la pompe et la face interne de la chemise et entre leurs portées de contact, une chambre dite annexe et,
  • d'autre part, l'un des éléments que sont la chemise et le corps comprend au moins indirectement notamment au niveau des portées précitées des moyens d'étanchéité de l'emmanchement de la chemise sur la face externe du corps de la pompe, l'ensemble comportant en outre des moyens de raccordement hydraulique de la chambre à un circuit annexe dans lequel circule un fluide d'échange thermique.
To this end, the subject of the invention is such a pump, in particular characterized in that:
  • on the one hand, around its external face, the pump body has means for removable attachment of a jacket capable of encircling the pump body by reserving between the external face of the pump body and the internal face of the shirt and between their contact spans, a so-called annex room and,
  • on the other hand, one of the elements that are the jacket and the body comprises at least indirectly in particular at the abovementioned bearing surfaces of the sealing means of the fitting of the jacket on the external face of the pump body, l 'assembly further comprising hydraulic connection means of the chamber to an annex circuit in which circulates a heat exchange fluid.

L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement :

  • figure 1 : une vue schématique d'une installation,
  • figures 2 et 3 : deux exemples de pompe selon l'invention.
The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the attached drawing which schematically represents:
  • FIG. 1: a schematic view of an installation,
  • Figures 2 and 3: two examples of pump according to the invention.

En se reportant au dessin, on voit que l'installation 1 comprend :

  • un réservoir 2 pour le produit à projeter,
  • un dispositif applicateur 3,
  • un circuit principal 4 comprenant au moins une pompe 5 qui, prélevant le produit stocké dans le réservoir, amène celui-ci au dispositif applicateur avec une pression prédeterminée.
Referring to the drawing, it can be seen that the installation 1 comprises:
  • a tank 2 for the product to be sprayed,
  • an applicator device 3,
  • a main circuit 4 comprising at least one pump 5 which, taking the product stored in the reservoir, brings the latter to the applicator device with a predetermined pressure.

Ces installations sont couramment appelées "AIRLESS" car le produit est projeté sans l'aide d'un gaz.These installations are commonly called "AIRLESS" because the product is sprayed without the help of a gas.

Classiquement, chaque pompe 5 comprend :

  • un corps 6 délimitant une chambre 7 dans laquelle se déplace axialement un piston 8 dont le déplacement est provoqué par le déplacement d'une tige 9 reliée à un moteur (non représenté) tel un moteur hydraulique,
  • des moyens 10 de contrôle dit d'entrée pour le passage d'un liquide depuis un circuit d'alimentation vers la chambre principale, et
  • des moyens 11 de contrôle dit de sortie pour le passage du liquide depuis la chambre principale vers un circuit alimentant un dispositif applicateur 3 tel au moins une buse de pulvérisation.
Conventionally, each pump 5 comprises:
  • a body 6 delimiting a chamber 7 in which a piston 8 moves axially, the displacement of which is caused by the displacement of a rod 9 connected to a motor (not shown) such as a hydraulic motor,
  • means 10 of said input control for the passage of a liquid from a supply circuit to the main chamber, and
  • means 11 for controlling said outlet for the passage of the liquid from the main chamber to a circuit supplying an applicator device 3 such as at least one spray nozzle.

Ces moyens de contrôle 10, 11 sont logés pour l'un (11) dans le piston 8 et pour l'autre (10) dans l'une (12) des faces 12, 13 extrêmes du corps de la pompe.These control means 10, 11 are housed for one (11) in the piston 8 and for the other (10) in one (12) of the end faces 12, 13 of the pump body.

Selon l'invention :

  • d'une part, autour de sa face 14 externe, le corps 6 de la pompe présente des moyens 15 de fixation amovible d'une chemise 16 apte à ceinturer le corps de la pompe en réservant entre la face externe 14 du corps de la pompe et la face 17 interne de la chemise et entre leurs portées de contact, une chambre 18 dite annexe et,
  • d'autre part, l'un des éléments que sont la chemise et le corps comprend au moins indirectement notamment au niveau des portées précitées des moyens 19 d'étanchéité de l'emmanchement de la chemise sur la face externe du corps de la pompe, l'ensemble comportant en outre des moyens 20 de raccordement hydraulique de la chambre à un circuit annexe dans lequel circule un fluide d'échange thermique.
According to the invention:
  • on the one hand, around its external face 14, the body 6 of the pump has means 15 for removable attachment of a jacket 16 capable of encircling the body of the pump by reserving between the external face 14 of the body of the pump and the internal face 17 of the jacket and between their contact surfaces, a chamber 18 called annex and,
  • on the other hand, one of the elements that are the jacket and the body comprises at least indirectly in particular at the aforementioned ranges means 19 for sealing the fitting of the jacket on the external face of the pump body, the assembly further comprising means 20 for hydraulic connection of the chamber to an annex circuit in which a heat exchange fluid circulates.

Les moyens 15 de fixation amovible comprennent des moyens de positionnement radial de la chemise autour du corps et des moyens de verrouillage axial de la chemise sur le corps.The removable fixing means 15 comprise means for radially positioning the jacket around the body and means for axially locking the jacket on the body.

Par exemple, le corps de la pompe présente deux portées 21 cylindriques sur lesquelles s'appuient localement la face interne de la chemise qui présente, à cet effet, également deux portés 22 cylindriques.For example, the pump body has two cylindrical bearings 21 on which the internal face of the jacket is supported locally, which also has two cylindrical bearings 22 for this purpose.

Les portées cylindriques d'une des deux pièces que sont la chemise et le corps de la pompe sont présentées par des collerettes 30 solidaires d'une des deux pièces précitées.The cylindrical surfaces of one of the two parts that are the jacket and the pump body are presented by flanges 30 integral with one of the two aforementioned parts.

Le moyen 23 de verrouillage axial peut consister en un système vis écrou voire en au moins une tige de vis qui s'engage dans une perforation radiale de la chemise et du corps de la pompe.The axial locking means 23 may consist of a screw nut system or even at least one screw rod which engages in a radial perforation of the jacket and of the pump body.

L'homme du métier sera apte à choisir le type de moyen de verrouillage le plus approprié.Those skilled in the art will be able to choose the most appropriate type of locking means.

Pour le montage, il suffit de faire coulisser la chemise sur le corps de la pompe, de verrouiller celle-ci puis de raccorder le circuit de chauffage.For assembly, simply slide the jacket over the pump body, lock it and then connect the heating circuit.

Ces particularités techniques sont intéressantes car, à tout moment, il est possible de transformer une pompe pour produit à froid en une pompe pour produit à chaud sous réserve d'ajouter, à l'installation existante, le circuit de chauffage qui est relativement indépendant du fonctionnement de l'installation d'application.These technical features are interesting because, at any time, it is possible to transform a pump for cold product into a pump for hot product subject to adding, to the existing installation, the heating circuit which is relatively independent of operation of the application installation.

L'invention permet d'avoir, à la chemise amovible prés, des pompes identiques pour l'un ou l'autre type de produits, ce qui concourre à la réduction du prix de revient et facilite la maintenance.The invention makes it possible to have identical pumps for one or the other type of product with the removable shirt, which contributes to reducing the cost price and facilitates maintenance.
