Description
Technical field
This utility model relates to feed pump technical field, particularly relates to a kind of constant pressure water supply pump.
Background technology
Along with being on the increase of skyscraper, high-level user pressure of supply water becomes the subject matter of water supply company, and in order to ensure the pressure of supply water of high-level user, water supply company needs by manual monitoring pressure of supply water, the most not only waste a large amount of manpower, and easily produce operating error.
Utility model content
This utility model mainly solves the technical problem in the presence of prior art, thus provides a kind of automatic holding constant voltage, good heat dissipation effect and the constant pressure water supply pump of length in service life.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
The constant pressure water supply pump that this utility model provides, including feed pump body and motor, described feed pump body is provided with water inlet and outlet, it also includes pressure transmitter, controller and converter, described pressure transmitter is connected on described outlet, described controller and converter are fixed on described motor, described controller is connected with described motor communication through described converter, and described controller is also connected with described pressure transmitter, and the outside of described controller and converter is additionally provided with the case of a closing, described case is detachable with described motor to be connected, described case is provided with cooling mechanism, described cooling mechanism is connected with described controller and converter respectively.
Further, described cooling mechanism includes the first heat-conducting plate, the second heat-conducting plate and heat sink, described first heat-conducting plate and the second heat-conducting plate upper surface with described controller and converter respectively contacts, described heat sink is positioned at the outside of described case, and be connected with described first heat-conducting plate and the second heat-conducting plate respectively, and the cross-sectional area of described heat sink is more than the cross-sectional area of described case.
Further, the upper surface of described heat sink is additionally provided with multiple radiating fin.
Further, the sidewall of described case uses transparent material to be made.
The beneficial effects of the utility model are: detected the pressure at the mouth of a river in real time by pressure transmitter, and feed back to controller, controller is by the rotating speed of converter regulation motor, thus automatically maintain the pressure of outlet constant, and, make controller and converter reach waterproof and dustproof and antiseptical effect by arranging case, improve its service life, meanwhile, the heat that cooling mechanism produces when can work controller and converter dispels the heat in time, this further improves service life.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is constant pressure water supply pump structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Refering to shown in Fig. 1, the constant pressure water supply pump that this utility model provides, including feed pump body 1 and motor 2, feed pump body 1 is provided with water inlet 3 and outlet 4, it also includes pressure transmitter 5, controller 6 and converter 7, pressure transmitter 5 is connected on outlet 4, controller 6 and converter 7 are fixed on motor 2, controller 6 is connected with motor 2 communication through converter 7, and controller 6 is also connected with pressure transmitter 5, and the outside of controller 6 and converter 7 is additionally provided with the case 8 of a closing, case 8 is detachable with motor 2 to be connected, case 8 is provided with cooling mechanism, cooling mechanism is connected with controller 6 and converter 7 respectively.This utility model detects the pressure at the mouth of a river 4 in real time by pressure transmitter 5, and feed back to controller 6, controller 6 regulates the rotating speed of motor 2 by converter 7, thus automatically maintain the pressure of outlet constant, and, make controller 6 and converter 7 reach waterproof and dustproof and antiseptical effect by arranging case 8, improve its service life, meanwhile, the heat produced when controller 6 and converter 7 can be worked by cooling mechanism dispels the heat in time, this further improves service life.
Specifically, cooling mechanism includes the first heat-conducting plate the 9, second heat-conducting plate 10 and heat sink 11, first heat-conducting plate 9 and the second heat-conducting plate 10 upper surface with controller 6 and converter 7 respectively contacts, heat sink 11 is positioned at the outside of case 8, and be connected with the first heat-conducting plate 9 and the second heat-conducting plate 10 respectively, and the cross-sectional area of heat sink 11 is more than the cross-sectional area of case 8.By the first heat-conducting plate 9 and the second heat-conducting plate 10, the heat on controller 6 and converter 7 surface is conducted to heat sink 11, utilize thickness thin and heat is diffused in air by heat sink 11 that area is big in time, its good heat dissipation effect, radiating efficiency height.It is also preferred that the left in order to improve radiating efficiency further, the upper surface of heat sink 11 is additionally provided with multiple radiating fin 12.
In this utility model, for the ease of observing controller 6 and the state of converter 7, the sidewall of case 8 uses transparent material to be made.
Above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
