Description

In-line pumping unit
Technical field
The present invention relates to a kind of pump-unit that is used for fluid dispensing system, for example potable water distribution system, fire-fighting system, park and agricultural irrigation systems and vehicle wash system.
Background technique
For foregoing application, generally use so-called ground type electric pump.There is different shortcomings in these electric pumps.Especially, their motor has cooling fan, and these cooling fans have very big noise and can disturb near these electric pump installation sites people.In addition, clearly these places must ventilate, and therefore nonventilated place is out of use.In addition, these pumps need a pedestal that is fixed.Another shortcoming is that electric tools has so-called prelubricated bearing, yet behind certain hour, these prelubricated bearings must be replaced.
Above the liquid entering hole with coaxial toward each other setting ((in-line) promptly in alignment) of described type and the electric pump of liquid outlet be known, therefore, these pumps can directly be inserted in the straight tube and not need to use the bend pipe connector.
Immersion electric pump that motor does not need cooling fan is known a period of time also.For this reason, it has been generally acknowledged that their noise is littler than ground electric pump, and do not need to ventilate or safeguard.Yet, must be arranged on them in the pond or be immersed in the liquid of institute's pumping.
In addition, it also is known in the so-called pressurized machine that the immersion electric pump is embedded, and that is to say, is used as the pipe fitting of the container of the liquid that pump immersed.This pressurized machine is vertical and needs suitable pedestal.This liquid inlet horizontal orientation and be positioned at the pressurized machine bottom, and liquid outlet is positioned at its upper end and vertical orientation.In this case, obviously can not be with pressurized machine and the installation in alignment of corresponding immersion electric pump.
Pressurized machine is horizontally disposed with, and the layout that is supported by saddle type that is fit to or support ring is known.Liquid inlet and outlet mutual coaxial setting at the pressurized machine two ends, the installation that therefore is in line in this case is possible.Yet, have the shortcoming and the horizontal dimension of pressurized machine and the fact of equal in length that need suitable support.
Summary of the invention
The purpose of this invention is to provide a kind of noise and be significantly less than face-pumping routinely, can be positioned in the room of non-ventilation, do not need pedestal or support, the pump-unit that can be in line and install and in fact do not need to maintain.
Can reach this purpose by the pump-unit that is used for fluid dispensing system according to the present invention, but described pump-unit comprises an insertion and has the interior immersion or the immersion electric pump of pressurized machine of the entrance and exit that is used for liquid, described entrance and exit all is positioned at the end of the close electric pump output of pressurized machine, and each other relatively and aim at along axis, it is characterized in that, pressurized machine comprises the bivalve, and this bivalve is spaced apart from each other.
If pressurized machine vertically is provided with, therefore its lower end does not need specific pedestal or other support for can directly being shelved on the conventional shape on any floor.Yet if preferred words, described pressurized machine obviously also can be horizontally disposed with.Such layout only needs a support in the pressurized machine end opposite at described entrance and exit place.
The sound absorption material can be filled up in space between described two shells.
Can clearly see from top narration, the invention provides a kind of installation that can directly be in line, pump-unit that noise is very little, if pressurized machine is vertical, it will have minimum design size.Known pump-unit can not obtain these results simultaneously.
Description of drawings
From subsequently the present invention an embodiment's the description being will be more readily apparent from.In the following description will be with reference to appended accompanying drawing, wherein:
Fig. 1 is the front view of the pump-unit of the present invention of straight line installation;
Fig. 2 is the plan view of seeing from above that the pump-unit of part excision is shown separately;
Fig. 3 is the vertical cross-section by Fig. 2 center line 3-3;
Fig. 4 is the part vertical cross-section by Fig. 3 center line 4-4;
Fig. 5 is for by predetermined number and the plan view pump group that constitutes at the identical modularization pump-unit of preceding accompanying drawing;
Fig. 6 is the front view of the pump group of arrow 6 directions among Fig. 5.
Embodiment
Shown in Fig. 1-4, pump-unit 10 comprises the immersion electric pump 12 (Fig. 3) of the routine of a positioned coaxial in pressurized machine 14.The pressurized machine person has whole parallelepiped shape and has base for supporting 16 near its lower end.
As shown in fig. 1, because it is shelved on the floor 54 simply, so pump-unit 10 do not need specific support or pedestal, and it remains on the appropriate location by its pipe 55 that inserts that is in line.Even under the situation of the pump assembly in Fig. 5 and Fig. 6, it directly is shelved on different pump-unit 10 on the floor 54 very simply, and connector 56 and 58 adds that system's collector 62 and 64 (support 60 with them) is enough to single assembly 10 is remained on the appropriate location.
The sidewall of pressurized machine comprises two shells, and for example, shell 18 is made by anodization duralumin and inner casing 20 is made by stainless steel.Even although the space between two shells 18 and 20 is empty (for example, comprising air) also to have obtained good noise reduction level, this space can be filled up with the muffler material of routine.Can see from Fig. 3, thereby trembleuse cup 22 is fixed in the lower end that keeps electric pump 12 on the inner casing 20, the remainder of electric pump hang on by connector 24 that whole top parts (headpiece) by 26 indications are gone up and by screw on connected element 42, connected element 42 self is by the head of screw in pressurized machine 14.Top part 26 comprises inlet 30 integrally formed with it and outlet 28, and relevant connecting passage.
Operation along with electric pump 12, from 30 flow of liquid that enter that enter the mouth cross downward bias from inlet passage part 32, therefore liquid flows between the inner side surface of the outer side surface of electric pump 12 and pressurized machine 14, arrive the lower end of electric pump 12, be inhaled into and leave by the electric pump inlet then by described out connector 24, the tapping channel 34 of flowing through the liquid along continuous straight runs being departed from leaves outlet 28 up to liquid.Can see that inlet 30 is aimed on identical axis 36 with outlet 28 and toward each other, formed the T shape passage of (in view of electric pump is vertical) liquid.This can make pump-unit 10 directly be inserted in the pipeline and connecting bend needn't be provided.
In illustrated specific examples, pump-unit 10 also comprises the whole control gear that is positioned at top part 26 bottoms by 44 indications.This control gear 44 comprises electronic cards 46 (electronic card) and display unit 48, all is encapsulated in the housing 38 with removable lid 50.This housing 38 also comprises a transducer 40 that is supported and be connected to pressure transducer 41 by top part 26.Thereby pressure transducer 41 can be measured and provides signal to regulate the operation of the motor of electric pump 12 to transducer 40 delivery pressure, and this can saving power.
Pump-unit 10 also comprises the liquid level sensor 52 that prevents that electric pump from operating under the no liquid condition.
From Fig. 1-4 and above description can clearly see, except above-mentioned advantage, pump-unit 10 is very compact, has very little global design size, present " clean and tidy " outward appearance, under any circumstance obviously have more satisfactory appearance than known pump device with same use type.
Pump-unit 10 can be represented a modular unit that can form pump assembly shown in Fig. 5 and Fig. 6, comprises 5 pump-units 10 and relevant connector 56 and 58 and two collectors 62 and 64 in this certain embodiments.This layout can provide a primer pump device (pilot pumping unit) and arrange, if when the primer pump device breaks down, another pump-unit in the pump group replaces it and automatically as primer pump.According to specific needs and design alternative, obviously the number of pump-unit can be different.
