The invention discloses a kind of piston manometer full-automatic pressure source, including pressure source controller, the input connection pressure sensor of pressure source controller, the output end connection motor of pressure source controller, the output end of motor is connected with piston and drive device.The present invention can be automatically controlled to the pressure source of piston manometer, counterweight weight that can be in automatic identification piston manometer, easy to operate, it is to avoid the system caused by the pressure indicator in automatic pressure source and the pressure gauge of piston meter have error is unstable.
Description
Technical field
The present invention relates to pressure gauge equipment technical field, specifically a kind of piston manometer full-automatic pressure source.
Background technology
Piston gage is a kind of high accuracy based on Pascal's law and the generation of hydrostatic equilibrium principle, height
The normal pressure metrical instrument of repdocutbility and high confidence level.Piston gage also normal abbreviation piston manometer or pressure gauge,
There is referred to as pressure balance, be mainly used in measuring room, laboratory and production or scientific experiment link makes as pressure reference device
With also having and piston gage directly applied into high reliability monitoring link the votings of local other instrument is monitored.
At present, intelligence（Numeral）The control mode of pressure source is all in set desired value, according to mesh Stress control
Mark pressure value sets control speed automatically, accurately pressure value control in target pressure value.But for the pressure of piston manometer
The power source overwhelming majority is all using control manually, because if using automatic pressure source, needing to set pressure every time after counterweight is placed
Desired value, troublesome poeration, if the pressure indicator in automatic pressure source and the pressure value of piston manometer have error, system can not
It is stable；Currently without the full-automatic pressure source of energy automatic identification counterweight weight.
The content of the invention
It is an object of the invention to provide a kind of piston manometer full-automatic pressure source, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the present invention provides following technical scheme：

Sensor, the output end connection motor of pressure source controller, the output end of motor is connected with piston and drive device.
It is used as further scheme of the invention：The motor is stepper motor or servomotor.
It is used as further scheme of the invention：The input of the pressure source controller is also associated with piston position sensing
Device.
It is used as further scheme of the invention：The pressure source controller is connected with pressure source.
It is used as further scheme of the invention：The piston and drive device are provided with piston micromatic setting.
Compared with prior art, the present invention can be automatically controlled to the pressure source of piston manometer, can be known automatically
Counterweight weight in other piston manometer, it is easy to operate, it is to avoid the pressure indicator in automatic pressure source and piston manometer
System caused by pressure value has error is unstable.
Brief description of the drawings
Fig. 1 is the structural representation in piston manometer full-automatic pressure source.
In figure：1- pressure sensors, 2- piston position sensors, 3- pressure sources controller, 4- motors, 5- pistons and driving

Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Referring to Fig. 1, a kind of piston manometer full-automatic pressure source, including pressure source controller 3, pressure source controller 3
Input connection pressure sensor 1, the output end connection motor 4 of pressure source controller 3, the output end of motor 4 and piston and
Drive device 5 is connected.
The motor 4 is stepper motor or servomotor.
The input of the pressure source controller 3 is also associated with piston position sensor 2.
The pressure source controller 3 is connected with pressure source.
The piston and drive device 5 are provided with piston micromatic setting.
The present invention can be automatically controlled to the pressure source of piston manometer, can be in automatic identification piston manometer
Counterweight weight, it is easy to operate, it is to avoid the pressure indicator in automatic pressure source and the pressure value of piston manometer have error to be made
Into system it is unstable.
The operation principle of piston manometer is pressed according to based on hydromechanical equilibrium principle and Pascal's law
Power metering.A kind of power is that the fluid in closed container is produced, the fluid force acted on piston, and another is by adding
The weight of specific weight on piston act in piston area produced by, this two power balances each other.
When the pressure in fluid is less than the pressure that counterweight weight is produced, piston position is in extreme lower position, when pressure is big
When the pressure that counterweight weight is produced, piston can be moved up, until maximum position, if pressure is just produced with counterweight weight
Pressure it is identical, counterweight position can be in centre position.
When the pressure source being connected with piston manometer, when being worked with certain pressure raising speed rate, when piston is by jack-up, due to
Piston position is up moved, and volume flow can increase suddenly, pressure is risen rate reduction, when pressure rises rate reduction, is stopped
Pressurization, system pressure is just approached with the pressure produced by counterweight weight（System pressure is equal to the pressure produced by counterweight weight
Plus frictional force, if counterweight is in transhipment state, frictional force can be ignored）, automatic identification counterweight weight is not required to pre-set
Pressure target value；Conversely, in down stroke, removing piston position after counterweight and being in peak, with the reduction of pressure, piston meeting
Move down, volume is reduced suddenly, make pressure rate reduction, when pressure rate of pressure reduction is reduced suddenly, stop pressurization,
System pressure is just approached with the pressure produced by counterweight weight（System pressure is equal to the pressure antifriction produced by counterweight weight
Power, if counterweight is in transhipment state, frictional force can be ignored）, automatic identification counterweight weight.Stop after pressurization, cut automatically
Piston position control is changed to, the position range of general piston is ± 1.5mm, position control within ± 1mm, just can meet inspection
The requirement for journey of establishing rules., can be with manual fine-tuning piston position if not installing piston position sensor.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
, can also be on the premise of this patent objective not be departed from formula, the knowledge that one skilled in the relevant art possesses
Make a variety of changes.
