Description

DESCRIPTION PUMP WITH A HEATING EQUIPMENT Field of application and current state of the technique The invention preferably includes a heating propeller pump or It relates to the radial pump. From the patent number EP 2150165 Bl, impeller pump or radial equipped with integrated heater pump is known. The heating device is tubular and has a forms part of the outer panel of the pump compartment. It is envisaged as a heating medium. inside the heating device along the impeller path to the drain of the pump chamber. water that circulates until it squirts out. as high as possible predicting heating performance or pumping water Intense effort to reach as good heating as possible elements are applied as thick-layer heating elements Another slab pump with integrated heater is known.

Purpose of the invention and reaching the goal The underlying purpose of the invention, with these with a heating device in which the problems of the situation can be solved. To create an equipped pump, to use a heating device to make it suitable and with high heating performance as much as possible, water in the pump or in the bearing beam as well as possible. is to heat.

For this purpose, with the pump having the features of claim 1 reachable. Advantageous or preferred developments of the invention, is the subject of other claims and is discussed in more detail below. has been explained.

Heating in a pump with pump housing and pump compartment limitation of the pump chamber in the radial direction of the assembly be placed in this pump compartment, which is used as foreseen. In particular, the heating device, the pump forms the outer panel around the partition. For this longitudinal axis of the heating device a tubular carrier with a round cross-section around it there is a beam.

According to the invention the bearing beam protrudes at least at one end rests on the plane perpendicular to the longitudinal axis or is carrier the beam is longer than the other in this peripheral area. this ledge in the area, the bearing beam is longer than usual. Moreover on the carrier beam with this along this plane or even this there is a short section or containment area that passes through the plane.

Thus, the carrier beam along the longitudinal axis of the containment area can determine the actual length Especially the storage space is long or if large. In this memory area, the bearing beam is as if a section or stays on top by a distance, and thus there is more Thus, with the invention, the heating device must be unique and unique. longer in some sections that do not need to be long possible to be created. Thus, for example, a pump It can be adapted to the body or the pump section. Also for this reason the type of enlargement of the surface of the heating device and thus it is possible to reach the heating power of these. This is below In the design of the invention, the carrier is the axial axis of the specified longitudinal axis. different height in the direction. or different lengths. This definitely protruding area and at least an enclosure area, preferably definitely a containment area predictable. Basically, the carrier beam or heating only in one section of the assembly, that is, in the protruding area. It is promised to be long and stand out from other shapes. subject.

In an advantageous design of the invention, the carrier beam It is envisaged that the end will be cut straight. This type of cut parallel to the specified plane, perpendicular to the longitudinal axis or from one direction it passes vertically because it is relatively easy to apply it is advantageous. On the other hand, so that the carrier breaks or on the flat side of the pump chamber of the heater adaptable. Heating device or carrier beam can be advantageously cut with a laser. The protrusion area can be easily removed by cutting the bearing beam curved at one end. can be created. Thus, at an angle of 5° to 45° to the longitudinal axis it can be stopped. Preferably 15° to 30° to the longitudinal axis can stand at an angle. Thus, the curved section in the supporting beam, ever increasing. and then again continuously decreasing. overhang area It is obtained in the form that will form.

In the design of the invention, the protruding area is a flatter cut carrier. a three or maximum overhang, rising very steeply from the beam constituent. and then descending ridge again. as part can be created. General ascent and descent in the overhang area may or may not be symmetrical. Like this The ridge area may rise slowly and then out of the maximum ridge. Then it can descend strongly and distinctly steeply.

In another embodiment of the invention, a protrusion area at the tip The trailing edge or cut edge of the bearing beam is continuous. can stretch. Neither protrusion nor angle is foreseen at this time advantageous, therefore both the production of the heating device and It is also easier to adapt to the pump compartment. Meanwhile The increase in the protrusion area is at least partially different can be created. Alternatively, the rear of the carrier beam edge may also be in a plane here. Inventive carrier beam as the main form, round transverse around the longitudinal axis sectional pipe type. The cylindrical tube it is advantageous. Approximately. with fixed panel thickness should be. Cylindrical tube with circular cross-section is particularly preferred. This type of pipe It is easy to create and can also be used in a sill pump or radial as an external pump chamber wall for use in the pump. It has good features. In general for corrosion resistance made of stainless steel as known for this purpose of use. can be produced.

In the advantageous design of the invention, the carrier beam or heating heating device or heating elements on the outside of the device is placed. Preferably, heating devices are placed in a large area. dispersed or only with a certain heating medium width It does not directly cover an area. Rather of course a certain or large area, at a certain distance from each other so that the field strength is approximately evenly distributed. can create. Especially a serious one, preferably. carrier at least 50% or more of the beam area is the heating. Preferably as heat transmission lines, these are various Because it can be worn in different ways, thick layered heat transmission lines eg silkscreen printed relevant output bold with layer paste Etc.

In the basic design of the invention, the heating device or same or essentially constant surface power of the heater can be predicted. Thus, the heating device or By providing equal heating on the main surface of the carrier beam and Thus, the heat transfer of the transported and heated liquid is also equal. it can be reached. To reach this, in this ledge area additional or extended heating device that would otherwise not be available predictable. Thus, the total power of the heating device, that the bearing beam surface extends over the ridge area may increase substantially.

In another basic design of the invention, in the projection area, the heating vehicle or heating device to different or different surface strength may have. On the one hand, there is no heating in the overhang area. the agent is not foreseen or only to a very low extent It can be reached by foreseeing the heating medium. You are the carrier metal by conduction of heat to itself, especially as bearing beam or for liquid transported when using stainless steel The heat transfer surface can be increased, generally with additional heating. accompanies. On the other hand, let the carrier beam in the overhang area by a means of heating added to the surface strength hitherto surface strength is predictable. So near the ledge area Especially good heat loss with transported liquid can be used, for example particularly fast or particularly good fluidity. Particularly the subject of the invention as a curb pump or a radial pump in the pump, the pump casing or the pump compartment at least one inlet inside and at least one outward from the pump chamber. There is an exit. This central inlet pump's central longitudinal the pump chamber and the axis of the rim carried along the sill. Removing the sill, the pump compartment It extends around it and is essentially ring-shaped. Pump the main area of the outer panel of the compartment is the specified heating straight with the assembly, so to speak, of the pump compartment It is formed in the form of a mantle panel.

From the pump chamber, at the far end of the pump chamber from the sill exit is foreseen. Meanwhile, the outlet pump compartment exits the width of the pump chamber, one width from the end and increases. Pump chamber outlet is in the area slightly ahead, for example Between 5° and 30° during half or third circulation perpendicular to the longitudinal axis of the pump at an angle It is advantageous that it increases and comes out of the exit hole. Sign out or The protrusion area of the heating device slightly in front of the outlet hole placed so that the pump compartment present here The large height that appears in the protrusion type can be used and can pass here. As mentioned earlier here enlarged heating with additionally more surface in general equipment can be used. separately transported here better heat loss due to better flow of water possible.

The other end of the heating device with an advantageous straight cut is the pump. the other axial end portion of the bulkhead, especially near the sill or so that it also surrounds the radial entry can be placed. Thus, the sill as usual in one plane or the heating device is straight at least from the pump chamber, which facilitates the cut end wrapping the axially symmetrical passing constraint is taken into account.

These and other features are in the claims. except from the description. and it will be clear from the drawings; meet here protected area determined by the following claims.
