Description
Technical field
The utility model is related to vacuum pump technology field, more particularly to a kind of energy-saving vacuum pump.
Background technology
The main purpose of vavuum pump, is to create the vacuum environment of subatmospheric power, so as to building cleaner ring
Border, good technique and product quality, therefore vavuum pump is widely used in petrochemical industry, manufacturing industry and hospitality industry environment
In.But existing Vacuum Package vavuum pump is constantly in running status at present, it can not only shorten electrical machinery life, and waste big
Measure electric energy.
Therefore, a kind of energy-saving vacuum pump is invented necessary to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of energy-saving vacuum pump, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme:A kind of energy-saving vacuum pump, including stop pressing
Button, start button, vacuum pressure switch and zero line, the stop button and start button are connected with major loop, described to start
The normally opened contact of button and the formation self-locking of the first auxiliary reclay, the zero line connects vacuum pressure switch common port, described true
The normally-closed contact of empty pressure switch is connected with the second auxiliary reclay, in the middle of the normally opened contact of the vacuum pressure switch and the 3rd
Relay is connected, and the normally opened contact of the 3rd auxiliary reclay connects the control line of A.C. contactor.
It is preferred that, the model of first auxiliary reclay, the second auxiliary reclay and the 3rd auxiliary reclay is city
Sell the serial relays of JZ7.
It is preferred that, the commercially available CJX2 Series AC Contactors of model of the A.C. contactor.
Technique effect of the present utility model and advantage:By setting the first auxiliary reclay, the second auxiliary reclay, the 3rd
Auxiliary reclay, pressure vacuum gauge, vacuum pressure switch common port, vacuum pressure switch and A.C. contactor, realize energy saving true
The real-time control of empty pump motor start and stop, effectively extension motor service life, save electricity.
Brief description of the drawings
Fig. 1 is the utility model technical principle schematic diagram.
In figure:1 stop button, 2 start buttons, 3 first auxiliary reclays, 4 second auxiliary reclays, in the middle of 5 the 3rd after
Electrical equipment, 6 pressure vacuum gauges, 7 vacuum pressure switch, 71 vacuum pressure switch common ports, 8 A.C. contactors, 9 zero lines.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of energy-saving vacuum pump as shown in Figure 1, including stop button 1, start button 2, true
Empty pressure switch 7 and zero line 9, the stop button 1 and start button 2 are connected with major loop, the start button 2 it is normally opened
Contact and the formation self-locking of the first auxiliary reclay 3, the connection vacuum pressure switch of zero line 9 common port 71, the vacuum pressure
Switch 7 normally-closed contact connected with the second auxiliary reclay 4, in the middle of the normally opened contact and the 3rd of the vacuum pressure switch 7 after
Electrical equipment 5 is connected, and the normally opened contact of the 3rd auxiliary reclay 5 connects the control line of A.C. contactor 8.
The model of first auxiliary reclay 3, the second auxiliary reclay 4 and the 3rd auxiliary reclay 5 is commercially available JZ7
Serial relay, the commercially available CJX2 Series AC Contactors of model of the A.C. contactor 8 set A.C. contactor 8 can frequency
Numerous switching circuit, with Small current control high current, divides, combined floodgate circuit manually relative to people, and it is more efficient, more flexible.
This practical operation principle:Start button 2, the self-locking of the first auxiliary reclay 3 are pressed, the second auxiliary reclay 4 obtains electric,
Vaccum pump motor starts, when pressure rises to presetting pressure upper limit, the changeover contact of vacuum pressure switch common port 71, in the middle of second
The dead electricity of relay 4, while the 3rd auxiliary reclay 5 obtains electric, vaccum pump motor is stopped;When pressure drops to presetting lower limit
During pressure, the changeover contact of vacuum pressure switch common port 71, the second auxiliary reclay 4 obtains electric, while the 3rd auxiliary reclay 5 loses
Electricity, vaccum pump motor starts, and presses stop button 1, and the dead electricity of the first auxiliary reclay 3, self-locking stops, and vaccum pump motor stops work
Make.
Finally it should be noted that:Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Equivalent substitution is carried out, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc.,
It should be included within protection domain of the present utility model.
