Abstract
The invention relates to a mechanical electronic dual-display roots flowmeter which comprises a roots bottom meter and a mechanical display unit, wherein the mechanical display unit comprises a counting gear shaft which is coaxially fixedly connected with one end of a rotor shaft, a thumb wheel for pushing a print wheel, a thumb wheel shaft for connecting with the thumb wheel and a gear group of the counting gear shaft, and the gear group can realize speed reduction of the axial thumb wheel shaft of the counting gear shaft; the roots flowmeter further comprises an electronic display unit; and the electronic display unit comprises magnetic steel arranged on a certain position of the print wheel, a flow sensor which is arranged on the circumferential side surface of the print wheel and used for sensing changes in a magnetic field of the magnetic steel and an integrating instrument connected with the flow sensor. The mechanical electronic dual-display roots flowmeter disclosed by the invention can solve the technical problems that an existing single-display type mechanical counting roots flowmeter can not perform temperature-pressure compensation, a single-display type electronic counting roots flowmeter has poor reliability, and a dual-display roots flowmeter taking a mechanical counter as the core is not accurate enough to count. According to the mechanical electronic dual-display roots flowmeter disclosed by the invention, the dual-display property is formed.
Description
Technical field
The present invention relates to a kind of Roots type flowmeter.
Background technology
Roots type flowmeter main body in the market is two kinds: 1, single explicit pure mechanical count Roots type flowmeter and pure electronic counting Roots type flowmeter; 2, with the mechanical counter be the two apparent Roots type flowmeter of core.
For single explicit Roots type flowmeter, pure mechanical count Roots type flowmeter can not carry out temperature and pressure compensation.Pure electronic counting Roots type flowmeter in case electronic section goes wrong, can not be counted.
In addition, be the two apparent Roots type flowmeter of core with the mechanical counter, just get the data on the mechanical counter, the situation that mechanical count and electronic counting are not complementary can appear during use, and cause the value sampling too big, count not accurate enough.
Summary of the invention
The object of the invention provides the two apparent Roots type flowmeters of a kind of mechano-electronic, and it has solved, and the explicit mechanical count Roots type flowmeter of existing list can not carry out temperature and pressure compensation, singly explicit electronic counting Roots type flowmeter poor reliability, mechanical counter are the not accurate enough technical matters of two apparent Roots type flowmeter counting of core.
Technical solution of the present invention is:
The two apparent Roots type flowmeters of a kind of mechano-electronic; Show and mechanical display unit at the bottom of comprising Roots; Said mechanical display unit comprises with the coaxial counting gear axle 5 that is connected of armature spindle 2 one ends, is used to promote the thumb wheel 12 of character wheel 7 rotations, is used to be connected the thumb wheel axle 14 of thumb wheel 12 and the gear set 6 of counting gear axle 5, and said gear set 6 can be realized the deceleration of counting gear axle 5 to thumb wheel axle 14;
Its special character is:
Said Roots type flowmeter also comprises electronic display unit;
Said electronic display unit comprises the magnet steel 8 that is arranged on the character wheel 7 on certain character wheel, is arranged on the flow sensor 15 of the changes of magnetic field that is used for responsive magnet steel 8 of this character wheel circumference side, the integrating instrument 4 that links to each other with flow sensor 15.
Above-mentioned electronic display unit also comprises pressure transducer 9 and temperature sensor 10.
On the most significant digit character wheel of above-mentioned character wheel 7 magnet steel 8 is set.
Advantage of the present invention is:
The present invention can realize two accurately countings that show.Armature spindle 2 drives counting gear axle 5 and rotates, thereby 6 rotations of driven gear group drive thumb wheel axles 14 through gear set 6 again and slowly run, and are character wheel 7 video datas thereby make mechanical counter.Simultaneously, certain character wheel of character wheel 7 drives magnet steel 8 and rotates around print wheel shaft 13, behind flow sensor 15, and video data on integrating instrument 5.So just constitute two showing.
