Description
Technical field
The present invention relates to a kind of heating cycle pump assembly, and it has feature of the present invention.
Background technology
This heating cycle pump assembly generally includes centrifugal pump and drives the motor of the centrifugal pump, electron speed regulator (example
Such as it is used for the frequency converter of motor) and internal electron adjuster, the control parameter in the adjuster is the rotating speed of motor, here, tune
Fast device and adjuster form a part for unit, and are typically provided the wiring beside pump case and electric machine casing
In box or electronic device box.The adjustment parameter of this adjuster is, for example, the pressure difference between the input of pump and output end, volume
Flow or the parameter being derived there.
In the modern heat circulation pump of aforementioned type, according to prior art, internal electron adjuster provide not only perhaps
More alternative adjustment curve, such as constant pressure curve, ratio pressure curve etc., and used in the unit there is phase
The internal microprocessor of software is answered, the microprocessor can be according to the actual conditions in heating equipment, the pressure particularly occurred
The temperature change of power change, pumped (conveying) medium, transport Stream etc., the specified value parameter of adjuster is set to match automatically with heating equipment.
The advantages of carrying out rated value adjustment to this self study of internal regulator is：Can be according to the requirement of heating equipment with intimate
Preferable mode is adjusted to pump, and therefore can matchingly be run with situation with relatively small number of electric energy.
On the other hand the heating cycle pump assembly by Frequency Converter Control of prior art is regarded as, is followed in these heat supplies
The peripheral control unit for being used for controlling revolution speed is provided with ring pump assembly.The peripheral control unit generally falls into the control of heating equipment center
A part for device.Interface for rotating speed control is the control signal on pump, for transmitting pulse-width signal,
This, pulsewidth determines effective voltage or frequency and thus determines the rotating speed of pump.Such pump for example can be in combustion gas warm
See in hydrophone, such as the gas heater in apartment as compact heating equipment, but they can also be used in it is small-sized
In house.
Different pump series is thereby establish, a side is the heat circulation pump of this self study, and they are existed by in-site installation
In heating equipment, the opposing party is the heat circulation pump by outside control, and they are generally arranged in water heater by manufacturer.
Because hydraulic demand in both cases is often identical, therefore heating cycle pump assembly is tied with regard to its machinery
It is practically without distinguishing for structure.However, manufacturer needs to produce two structures all the time for identical pump case connection data
Series.Based on the reason for the spare part, it is necessary to be always the different heating cycle pump assembly of each foregoing store, this makes
Cost is very high and costly.
For the larger heat circulation pump of structure (such as being mounted in parallel using two to eight pumps as one group), according to prior art
(model Magna UPE Grundfos pumps), it is the single heat supply each to these from outside with internal electron adjuster
Circulating pump implements control, here, not being that internal regulator is exerted one's influence in itself, and is only to preset rated value.
The content of the invention
In this context, it is an object of the invention to provide a kind of such heating cycle pump assembly, the heat supply to follow
Ring pump assembly not can be used only in the heating equipment by internal electron conditioner operation, but also can use with
In heating water's device of peripheral control unit, or it can also use in combination.
The purpose of the present invention is realized by a kind of heating cycle pump assembly with the technology of the present invention feature.The present invention's
Preferred embodiment is provided by following description and drawings.Herein according to the present invention, the spy provided in the specification and illustrated in the drawings
Sign can both be used alone, and can also be designed by the way that appropriate combination is further to technique according to the invention scheme.
There is the centrifugal pump driven by motor according to the heating cycle pump assembly of the present invention.The unit, which also has, is used for electricity
The electron speed regulator of machine and the internal electron adjuster using motor speed as control parameter, here, speed regulator and adjuster are formed
A part for unit.According to the present invention provided with the signal input part for implementing outside control to motor, and for electric from inside
Sub- adjuster is switched to outside rotational speed governor or the device for connecting outside rotational speed governor.
Therefore, basic thought of the invention is to make to be integrated in one according to foregoing pump type known in the art, in addition also
Devise the combination on controller/adjuster, the combination under this form can't be realized at present.According to the heat supply of the present invention
Circulation pump assembly can be advantageously employed its internal electron adjuster and carry out work, can also be using outside rotational speed governor come work
Make, and worked in combination using internal electron adjuster and outside rotational speed governor, for example, unit using internal regulator come
Work, and only controlled when connecting by outside rotational speed governor.That is, it is not necessary to only with a pattern or another pattern
Operation, but can be combined by favourable mode.
Signal input part on particularly preferred heating cycle pump assembly is by the Electric plug with shutter structure that is arranged on machine unit shell
Into.In the present invention, it both can be male type male component or female male component to connect plug.Pacified current
In heat circulation pump in heating water's device and using pulse-width signal control rotating speed, this signal input part is considered as
Prior art.According to the present invention, this signal input part can be formed in the form of other, for example, when signal passes through electric power electricity
During cable modulation transmissions it is made up of electrofilter, or when signal is transferred wirelessly by infrared ray, bluetooth or other kinds of
Receiver is formed.
Here, for internal electron adjuster to be switched into outside rotational speed governor or for connecting outside rotational speed governor
Device may be designed so that the device can be automatically determined advantageously, if peripheral control unit in connection, and it is determined that connection
Peripheral control unit enduringly or is when necessary switched to during upper peripheral control unit as requested.It may be thus possible, for example, to by suitable
Electronic circuit determine whether signal input part is connected with peripheral control unit according at a certain time interval.Due to outer
Portion's controller generally also electronically works, thus this can by corresponding " shaking hands " (" hand shaking ") or
Suitable proof cycle determines.
According to the invention, it is further possible to realized simple switching by means of the switch on pump assembly, the switch for example by with
