The method of data-collection durability.
Background technology
Mainly using permanent magnet is installed on character wheel, character wheel rotates a circle electronic counter in gas meter, flow meter currently on the market,
Tongue tube is attracted with release once, one pulse signal of electronic counting means is transmitted further to, so as to fulfill electronic counting.
The transmission of mechanical counter three-level is using 25 in existing gas meter, flow meter:3 step-down ratio, rotating speed is slower, into
During row endurancing, the time of experiment is longer.
Gas meter, flow meter data-collection durability measuring method is for measuring mechanical counter and electronic counter in gas meter, flow meter
Between counting error, according to the endurancing of GB/T 6968-2011 diaphragm gas meters require, with big flow operation tested
Gas meter, flow meter, 2000h or 5000h may be selected in run time, and by taking 2.5G gas meter, flow meters as an example, permanent magnet is installed on thousand points of position character wheels
On, 5000h is run under big flow, mechanical counter show value is 20,000 sides, and thousand points of position character wheels just have rotated 2,000,000 circles, i.e., dry
Reed pipe has been attracted 2,000,000 times, it is clear that experimental period of the existing intelligent gas meter before the method for its data-collection durability is measured
It is longer, it is not easy to the progress subsequently measured.
The content of the invention
The present invention overcomes the transmission of mechanical counter three-level in the prior art using 25:3 step-down ratio, exists
Rotating speed is slower, when carrying out endurancing, time of experiment longer deficiency, there is provided a kind of to be driven than tradition machinery counter
Than the mechanical counter for increasing by 10 times compared to rotating speed.
To achieve the above object, the present invention uses following technical scheme：
A kind of mechanical counter, it includes counter frame, first is offered successively from top to bottom in the side of counter frame
Mounting hole and the second mounting hole, the 3rd mounting hole and the 4th installation are offered in the opposite side of counter frame successively from top to bottom
Hole, is provided with first axle in first mounting hole, is set with rounding wheel in the first axle, installation in second mounting hole
Have the second axis, be sequentially installed with integer character wheel, decimal character wheel and thousand points of position character wheels from left to right on second axis, it is described into
Position wheel coordinates with integer character wheel, decimal character wheel and thousand points of position character wheels respectively, be provided with the 3rd mounting hole two level driving tooth,
Level-one driven tooth is installed on the two level driving tooth, level-one driving tooth, the 4th peace are installed in the level-one driven tooth
Dress is provided with three-level driving tooth in hole, and two level driven tooth, the level-one driving tooth and level-one are provided with the three-level driving tooth
Driven tooth is ratcheting, and the two level driving tooth and two level driven tooth are ratcheting, and the three-level driving tooth and thousand points of position character wheels are ratcheting, and
Magnet steel is installed on described thousand points of position character wheels, pulse sampling circuit plate is installed below the counter frame.
Further technical solution is that the number of teeth of the level-one driving tooth is 52, the level-one driven tooth
The number of teeth is 65.
Further technical solution is that the number of teeth of the two level driving tooth is 32, the two level driven tooth
The number of teeth is 17.
Further technical solution is that the number of teeth of the three-level driving tooth is eight, the number of teeth of described thousand points of position character wheels
For ten.
Further technical solution is that counting tongue tube, and the meter are provided with the pulse sampling circuit plate
Number tongue tube is immediately below thousand points of position character wheels.
Further technical solution is that the pulse sampling circuit plate is fixedly mounted under counter frame by screw
Side.
Further technical solution is to be equipped with baffle ring in the 4th mounting hole and three-level driving tooth junction.
First by selecting the level-one driving tooths of the different numbers of teeth, level-one driven tooth, two level driving tooth, two in the technical program
Level driven tooth, three-level driving tooth and thousand points of position character wheels, so that this programme Counter speed increasing ratio is 5:6, pass through level-one master
Moving teeth is engaged as power input tooth with level-one driven tooth, and two level driving tooth forms duplex with level-one driven tooth screw threads for fastening
