Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
A kind of volumetric metering station weighing device of metering hydraulic cylinder, referring to Fig. 1 to Fig. 2, metering hydraulic cylinder is series at
On the liquid stream circuit lines at volumetric metering station, the input end in liquid stream circuit is connected to standard capacity measure group, outlet end connection meter
Hydraulic cylinder is measured, the commutation element for driving liquid commutation in metering hydraulic cylinder, the both ends of metering hydraulic cylinder are additionally provided on liquid stream circuit
It is equipped with clearance compensation type between liquid stream circuit lines and connect 31, bottom part down is equipped with Weighing mechanism, and Weighing mechanism includes multiple
Position spring 30, the cylinder being mounted on outside spring 30 further include being mounted on the big pallet 25 of spring on 30 top of spring and being mounted on
The spring adjustment disk 29 of 30 bottom of spring is threadedly coupled between spring adjustment disk 29 and spring 30 via adjusting, the big pallet 25 of spring
The small pallet 27 of sensor and corresponding support rod 26 are also equipped between spring adjustment disk 29, in the small pallet 27 of sensor and support
Weighing and sensing element is equipped at stress between bar 26.
Clearance compensation type connection 31 includes the liquid stream circuit lines as inner tube, the metering hydraulic cylinder both ends as outer tube
Connecting tube, there are clearance fit between inner and outer tubes, length of fit is greater than 30mm, and inner tube is in above or below outer tube.
Weighing and sensing element includes the pressure cirrhosis instrument for being in below metering hydraulic cylinder, being installed on inside spring 30.
Container is placed on the container of on-line measurement special joining device and piping connection is needed in original state
Line measures on 30 balancer of spring, empties container, adjustment spring adjustment disk 29, and the big pallet that makes to weigh of spring 30 leaves cylinder about 2
At this moment millimeter adjusts screw, be in contact by sensing small tray scale weight sensor with container, be in weighing sensor
With and without critical state, with regard to this weigh just tense complete.
In specific implementation, piping connection fluid on-line measurement special connector.Two different balance methods: a kind of
It is that, using two end face fluid stopping devices, immersible pump seal box solves pipeline and limits fluid on-line measurement problem；Utilize balance counterweight
Principle solves volume hollow body weight weight, and fluid weight is light, the low problem of caused weighing resolution ratio；Another kind is using direct insertion
Dedicated fluid on-line measurement connector cooperates Spring balancer, solves piping connection and volume hollow body weight weight, fluid weight
Gently, the low problem of caused weighing resolution ratio.
Balance can solve the problems, such as that error is big in fluid on-line measurement and resolution ratio is low with gentle spring trim, because of method
Its different effect also can a great difference.
Counter weight type balance trimmed equilibrium method and spring trimmed equilibrium method, substantial difference and implementation method and odds
Compared with: counter weight type balance trimmed equilibrium method and spring trimmed equilibrium method, maximum difference are threshold values difference.
Spring trimmed equilibrium method refers in claiming reforming process, falls although being unable to complete equipilibrium by the skin of title object, claims
Object is similar with both peelings.Only spring elongation is larger, and strain pulling-down is smaller.Installation and adjustment method: spring is flat
The measurement of weighing apparatus method: spring 30 and deformeter are acted on by title object simultaneously, and gravity is all undertaken by spring 30 when there was only skin by title object, when
When net object participates in, the two shared.This is installation principle.Specific installation spring 30 and deformeter are mounted on a container side by side
In, spring 30 and deformeter relative position are adjustable.Debugging: when skin net by title object, spring whole stress, deformeter is at critical state
Or one small value of setting.Then, the weight for determining value is added on skin, (such as: 10 kilograms.This depending on net weight to be claimed and
It is fixed.) see strain-ga(u)ge reading.For the number centainly than practical object heavy and light, difference is exactly the power that spring 30 acts on.Reading is that deformeter is made
Power.The ratio of they and actual net weight is exactly their ratio.
Embodiment 2, the present embodiment principle with embodiment 1, it is specific the difference is that: as shown in figure 3, weighing and sensing element
In pressure cirrhosis instrument replace with 33 element of lever, one end of lever 33 is fixed on spring 30 in 33 element of lever, the other end
Weights 34 are installed, the installation of fixed pivot 32 of 33 element of lever is on the ground.Spring adjustment disk 29 be externally provided with storage box with
Dispose counterweight.
Counter weight type balance trimmed equilibrium method, which is matched, usually uses balance, and weighs and deform to complete by cirrhosis instrument.From
It is seen in principle, cirrhosis instrument and 30 scale of spring are a principles, and only, cirrhosis instrument is Light deformation, and 30 scale deformation ratio of spring is hard
Become instrument macroscopic view.Counter weight type balance trimmed equilibrium method: with balance is flatted against, cirrhosis instrument is leaned in work, seem it is unrelated with balance, actually
Because the fulcrum of balance exists, the weight reflected on cirrhosis instrument is the half of actual weight.
Balance claims object, is counterweight and by the balance of title object.Such as: 5 grams of counterweight can only balance 5 grams of article, be more than
5 grams are just bowed, and are just come back less than 5 grams.The threshold values of balance is exactly 5 grams.Claim article with 30 scale of spring, it is assumed that 5 grams of article makes bullet
Spring 30 extends 5 millimeters, and 1 gram of article makes spring 30 extend 1 millimeter.The threshold values of 30 scale of spring movement is infinitesimal one a
Number, it may also be said to not have threshold values, think determining threshold values without us in other words.In this sense, counter weight type balance trim
Balancing method can accomplish to remove the peel completely.It can provide precision higher measured value.
Skin has not a particle of influence to weighing when measurement, however in embodiment 1,30 trimmed equilibrium method of spring passes through technological means
Balance peeling can also be completed, but subsequent weighing measurement skin still has an impact to weighing.Times score of skin portion skin in other words,
The weighing process of net object is still engaged in.It is also possible that saying, the stretching variation of cirrhosis instrument has the participation of spring 30 always.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
