Definitions
- the present invention relates to a pumping device.
- Domestic pumps are known, in particular horizontal pumps self-priming, including a hydraulic part and a motor, the motor actuating the hydraulic part.
- This hydraulic part generally comprises a pump body with several wheels (multicellular pumps, typically 4 to 5 floors). It is usually necessary to cool the engine.
- Domestic pumps are known, called standard, in which the engine is cooled by forced ventilation, with an apparent carcass (for example in aluminum).
- a major disadvantage of these pumps is related to the inconvenience caused by the noise level they reach in operation.
- the noise level of these pumps is all the more undesirable when these pumps are surface pumps for domestic use, with application to, for example, the housing and agriculture.
- the invention proposes a pumping device comprising: pump with a hydraulic part and a motor actuating the hydraulic part; a engine cooling fan, having a suction side and a side delivery to the engine; a partition between the suction side and the side of fan discharge; and a housing in which are the pump, the fan and the partition, the housing having a suction port on the same side of the partition as the suction side of the fan.
- the invention proposes a pumping device comprising a pump with a hydraulic part and a motor actuating the hydraulic part as well as a fan.
- the engine cooling fan has a suction side and a discharge side to the engine.
- the device further comprises a partition between the suction side and the discharge side of the fan and a housing in which are the pump, the fan and the partition.
- the housing has an orifice on the same side of the partition as the suction side of the fan.
- the partition allows to isolate the cold air in depression on the suction side by the hot air fan in overpressure on the discharge side, relative to the partition.
- the air pulsed by the fan especially on the engine, can not be directly pushed back to the suction port.
- the elimination by the partition of direct a Vogellic trajectories (ie in a straight line) between the pump and the suction port attenuates the noise of the pump and further improves the engine cooling.
- Figures 1 and 2 show a partial section, without scale, of a pumping device according to the invention, in vertical median planes and horizontal, respectively.
- the pumping device 10 comprises a pump 20 with a hydraulic part 22 and a pump motor 28.
- the part hydraulic pump may for example have a pump body 26 containing one or several pump wheel (s), as known in the art.
- the hydraulic part can, if necessary, have a reservoir 24.
- a bearing 27 is between the engine and the body.
- a fan 30 is connected to the motor, for example fixed to the motor casing. This fan has a suction side 32 and a discharge side 34, towards the 28.
- the fan 30 may for example comprise blades fixed to a hub (not shown).
- the device 10 further comprises a partition 40 disposed between the suction side 32 and the discharge side 34 of the fan 30 and a housing 50.
- the partition can for example be monobloc with the housing 50.
- the pump 20, the fan 30 and the partition 40 are arranged inside the casing 50.
- the casing has a suction port 52 located on the same side of the partition 40 as the side 32
- the partition and the casing form, on the suction side, a suction chamber.
- Current lines on the figures symbolize possible trajectories of the air sucked into the crankcase.
- the motor 28 actuates the wheels of the pump, typically via a rotor shaft (not shown) extending along an axis 15 of rotation of the motor 28, as it is known from the art.
- the pump is axial suction and radial discharge. In operation, the fluid centrifuged by the pump wheels follows a pumping current indicated by solid arrows on Figure 1.
- the blades of the fan 30 may for example be driven by the rotor, itself driven by the motor 28. Air is thus pulsed from the side suction of the fan 30 to the discharge side, that is to say towards the engine 28. More precisely, the air can be pulsed on fins (not shown) of the motor, thus ensuring its cooling.
- the partition separates the suction side from the discharge side of the fan, if although in operation, the air pulsed by the fan on the motor can not (or almost not) to be directly pushed back to the suction port.
- the partition eliminates therefore aeraulic trajectories direct from a point downstream of the partition (side fan discharge) to the suction port. So the sounds coming from motor (or motor noise) or the hydraulic part (hydraulic noise) and likely to escape through the suction port are attenuated by the partition.
- the partition attenuates or even eliminates a phenomenon of re-circulation of the air pulsed by the fan towards the suction side of the fan. Forced air comes mainly from the suction chamber where the air is cooler than in the overpressure zone. Thanks to the partition, there is no or little air, which after being pulsed on and heated by the motor, circulates again through the fan. It follows that cooling gains efficiency over pumping devices in the art prior. Typically, the temperatures of the areas of depression and overpressure are equal to the ambient temperature plus 5 to 15 ° C. Thanks to the partition, the temperature gain in the engine cooling can be between 10 and 20 ° C, preferably about 15 ° C. Thus, with equal cooling efficiency, the airflow needed to cool the engine is decreased compared to the devices of the prior art. Therefore, the noise generated by the fan can be decreased, by adapting the power of the fan.
- the suction port 52 of the housing 50 is off-axis relative to the axis of rotation of the motor 28 of the pump 20, the axis of rotation of the fan being preferably aligned with this axis.
- Such an arrangement of the orifice 52 makes it possible to avoid the propagation of sounds towards the outside and along the axis 15, that is to say sound coming directly from the motor 28 and the fan 30.
- the suction port 52 is masked, in order to create an effect of baffle in the air circulation.
- the casing may, in a mode of embodiment, have a lip 57 facing the suction orifice 52 (that is to say the overhanging) to create a baffle on the path of the air sucked by the fan 30 and coming from outside the housing 50.
- This lip 57 is for example formed by one end of the hull 59 of the dashboard of the housing, as will be discussed below.
- This baffle eliminates direct paths between the fan and the orifice suction, thereby reducing the noise generated by the pump and, in particular, by the fan.
- the suction port 52 is next to the partition. It should be noted that the effect of chicane is so much more efficient than the partition limits the re-circulation of air to the suction port. The noise attenuation effect resulting from the baffle does not simply add to the attenuation effect resulting from the partition but is therefore associated with it.
- the casing 50 further has an orifice 54 of discharge side opposite to that of the suction port 52, relative to the partition 40.
- the discharge orifice 54 may for example be located in the vicinity of the inlet 25 of the pump 20, as in the embodiment illustrated in FIGS. Figures 1 and 2.
- the arrangement of the pumping device 10 according to the invention makes it possible to limiting direct air paths, in particular between the engine (or the wheel center, partly) and the discharge port.
- the housing 50 has a continuous portion 56 in engine view 28. "Continuous" means a part without backflow against the engine.
- the pumping device 10 can be designed, according to the invention, so as to limit or even eliminate the direct aeraulic trajectories between on the one hand the motor 28, hydraulic 22 and 30 fan parts and secondly the suction and discharge ports 52,54.
- the noise level of a device 10 pumping according to the invention can typically be less than 48 dBA (pressure measured in accordance with measurement standard EN 12639 class 2), while the pumping devices of the prior art provide, in operation, levels of noise typically greater than 53 dBA.
- the device further comprises an isolation phonic 58 in the housing 50.
- the casing may for example be coated with sound insulation on its face internal.
- the inner face of polyurethane material may be coated.
- expanded, of density for example between 40 and 60 kg / m3, preferably close to 52 kg / m3 and with a thickness of between 10 and 30 mm, preferably close to 15 mm.
- the expanded polyurethane material may, for example, be injected hot.
- the polyurethane material may for example be in the form of one or several sheets of foam approximately 15 mm thick glued to the crankcase the output of the crankcase injection.
- the expanded polyurethane material can in turn be coated a polyurethane film with a thickness of between 15 and 40 ⁇ m, for example 25 ⁇ m, to improve sound insulation.
- a polyurethane film with a thickness of between 15 and 40 ⁇ m, for example 25 ⁇ m, to improve sound insulation.
- Such a film allows especially to improve the isolation of the low frequencies.
- a polyurethane foam sheet of about 15 mm thick glued to the housing at the outlet of the housing injection, coated with a film polyurethane of 25 ⁇ m arranged on the inner face of the housing, allows a gain of 3 dBA on the noise level of the pumping device 10 in operation, by compared to a pumping device without sound insulation.
- a passage sufficient for the circulation of air to inside the housing so as not to interfere with cooling.
- a space of ventilation greater than 5 mm around the engine, between the engine fins and the casing (or possibly the sound insulation) may be appropriate for a device 10 whose pumping capacity is close to that of a pump classic horizontal self-priming household.
- This space can for example be 10 mm ( ⁇ 5 mm), which offers a satisfactory compromise between efficiency of cooling and compactness of the pumping device.
- the partition 40 has an opening 48 across of which is the fan 30, a clearance being provided between the opening 48 and the fan 30.
- the peripheral (radially) wall of the fan does not touch the partition, in order to minimize the propagation of vibrations towards the crankcase, which are source of noise.
- the partition 40 can be connected to the housing, for example to be monobloc with the casing 50.
- a Standard domestic pump can thus be mounted in the pumping device.
- the pumping device 10 according to the invention proves particularly well Suitable for use with a domestic pump, given its qualities sound insulation.
- Such a pump is a domestic, horizontal, self-priming surface pump.
- a pump is preferably multicellular (for example 4 to 5 stages, wheels mounted on the motor shaft) with axial suction and upward radial discharge (like the embodiment shown in the figures).
- the motor is for example single or three-phase (230 - 400 V / 50 - 60 Hz). It should be noted that the noise levels mentioned above are those obtained on a 50 Hz network.
- the pump typically offers the following characteristics: flow rates up to 6 to 10 m 3 / h; maximum operating pressure up to 6 - 10 bar; ambient temperature range from + 5 ° to + 40 ° C and suction head up to 10 m.
