Description
Technical field
The utility model relates to a kind of rotor water gauge, in particular to it is a kind of it is highly sensitive not only can direct-reading water consumption, but also can
The water consumption is sent into rotor water gauge afield with digital signal.
Background technique
The summary counter (also referred to as counting character wheel group 9) that rotor water gauge is used to measure according to it is placed in water or is not interposing at
In water, wet-type meter or dry-type meter are divided into.
1, the mode of wet-type meter driving summary counter are as follows:
The impeller-driven being set in water meter housing is set to the central gear on pallet, and central gear drives setting again
In in gearcase between lower clamp plate and upper clamp plate gear set (central gear be located at transmission head end and corresponding in gear set
0.0001m3The gear of measurement unit engages), the gear of the driven end in gear set is engaged with worm gear, and worm gear drives character wheel again
1m in group3The character wheel of measurement unit rotates a word, to realize that summary counter counts.
Advantage: due to being all between the low level counter wheel in impeller, central gear, gear set, worm gear and summary counter
Pass through direct geared engaged transmission energy, therefore, metering sensitivity with higher and precision.
Disadvantage: since above-mentioned component is directly to engage, sealing waterproof problem therebetween can not be solved thoroughly, in general, through one
After section time use, these components, which are substantially all, to be dipped in the water stretched upwards, in this way, when summary counter is with photoelectricity
Direct-reading circuit and when water can be sent to the water meter of distal end with digital signal, the waterproof construction of the photo-electronic directly reading circuit just becomes
It is considerably complicated, it is careless slightly, then it will lead to the effect that the photo-electronic directly reading circuit loses photoelectricity acquisition water data.
2, the mode of dry-type meter driving summary counter are as follows:
The impeller-driven central gear being set in water meter housing, central gear drive gear set again, gear set by with
The engagement of worm gear drives the low level counter wheel in summary counter again.
Impeller is sealed in watchcase inner cavity by lower tray, and central gear is placed on lower tray, gear set and cumulative meter
Number devices are placed between lower clamp plate and upper clamp plate on lower tray, and dial plate is set on upper clamp plate, impeller and central gear it
Between connected using the contactless mode of magnetic coupling, when the impeller is rotated, driving central gear rotation, the then tooth by successively engaging
Power is transferred to summary counter and counted by wheel group, worm gear.
Advantage: since central gear, gear set, worm gear and summary counter are arranged on lower tray, and lower tray
Be sealed in watchcase upper port, the water in watchcase inner cavity will not soak upwards it is unrestrained, therefore, the central gear being set on lower tray
The waterproof performance of equal components improves naturally, when summary counter is that can send out with photo-electronic directly reading circuit and with digital signal water
When sending to the water meter of distal end, the service life of photo-electronic directly reading circuit can be greatly improved.
Disadvantage: in general, water can make impeller generate higher rotation speed when flowing through water meter, due to impeller and central gear it
Between using the contactless kinetic energy transferring structure of magnetic coupling, then the power coupling spirit between the impeller and central gear of high-speed rotation
Sensitivity will be deteriorated.I.e. initial in impeller rotation, central gear makes the speed of its response coupling slower due to the resistance of itself；And
After impeller stops high speed rotation, central gear extends due to the time that the inertia of itself can make it stop rotating.In this way, will lead to
Impeller is asynchronous with the rotation of central gear, causes the circle number of each spinning different, so as to cause the meter of final summary counter
Count existing deviation.
