A kind of pressure film scaling method and device, including load transducer, hydraulic jack, cushion compound, special cylinder and small ball, the hydraulic jack, which is placed on, to be placed on on fixed pan, being calibrated pressure film in hydraulic jack, special cylinder is located on pressure film, and small ball is placed in special cylinder upper surface.Upper fixed pan is contacted with small ball, makes cylinder and jack contact position uniform force, can meet calibration test request；Cushion compound is placed between pressure film and special cylinder, prevents pressure film contaminated；Hydraulic jack installed load sensor can monitor service load value in real time；Test of many times under same pressure reduces test error.
Description
Technical field
The present invention relates to a kind of pressure calibration scaling method and devices, particularly, are related to a kind of pressure calibration method and dress
It sets.
Background technology
Currently, with the development of economy, various kinds of equipment optimizes constantly, it is allowed to have on the basis of original higher strong
Degree needs to carry out test analysis to its mechanical property.For contacting with each other, the stress state for the two articles that contact area is small,
Conventional test device is unable to measure；In measurement range, pressure film can directly measure again the contact in its measurement range
Stress, and do not interfere with actual working pressure.
Pressure film is demarcated by counterweight, it is cumbersome, contact surface is rough, the gravity of per unit contact area compared with
It is small, calibration request cannot be met, therefore, there is an urgent need to a kind of methods of energy nominal pressure film.
Invention content
The object of the present invention is to provide a kind of pressure film calibration scaling method and devices, solve existing scaling method
Defect, can obtain uniform load, with what load display was read compare according to five groups of pressure value is measured, completion
Calibration.
The technical solution adopted in the present invention is, a kind of pressure film calibration scaling method and device, according to the following steps
Implement：
Before experiment, by hydraulic jack 8 between fixed pan 10 and fixed pan 3, and one is kept with fixed pan 3
Fixed distance, placement force film 7, cushion compound 6, special cylinder 5 and small ball 4, and there are a small amount of gaps；Hydraulic pressure
8 upper surface of jack is sequentially placed pressure film 7, cushion compound 6,5 body of special cylinder and small ball 4.
On-test, opens hydraulic pump 1, moves up hydraulic jack by control valve 2, small ball 5 is made to encounter fixed pan
3, observation load transducer display 9 reaches specified pressure value, stops control valve 2 and operates, continues 20s；Adjusting control valve, under
Drop hydraulic jack 8, take out pressure film 7, read pressure value, and with the 9 show value comparative analysis of load transducer display.
Same pressure value is tested in triplicate, is taken five groups of data, is compared and analyzed after the completion of experiment.
The pressure film calibration scaling method and device, feature of the present invention also resides in：
This method use pressure film calibration caliberating device structure be, hydraulic jack between two fixed pans,
The pressure film and cushion compound being calibrated are placed in hydraulic jack upper surface, and special circle is placed on pressure film and cushion compound
Cylinder and small ball, there are certain gaps with fixed pan for small ball.
For substandard pressure film, rating test can be carried out to it.
The invention has the advantages that can not only be demarcated to applying pressure value, but also can be to different size pressure
Power film is demarcated, simple in structure, and convenient test, range are wide, is equally applicable to other pressure test products.It specifically includes：
1) invention installed load sensor in hydraulic jack, and pressure is monitored by load transducer display in real time
Force value.
2) reasonable design, upper fixed pan are contacted with small ball, make cylinder and jack contact position uniform force, can be full
Foot calibration test request.
Analysis comparison is carried out by repeatedly measuring pressure under same pressure value, reduces rating test error.
Description of the drawings
Attached drawing 1 is the pressure film caliberating device structure chart of the present invention.
The meaning of figure label is：1. hydraulic pump, 2. control valves, fixed pan on 3., 4. small balls, 5. special cylinders, 6.
Cushion compound, 7. pressure films, 8. hydraulic jacks, 9. load cell displays, 10. times fixed pans.
Specific implementation mode：
The present invention is described in detail with reference to the accompanying drawings and examples.
Referring to Fig.1, the pressure film calibration caliberating device structure that the method for the present invention uses is that hydraulic jack 8 is located at upper
Between fixed pan 3 and lower fixed pan 10, the pressure film 7 being calibrated and cushion compound 6 are placed in 8 upper surface of hydraulic jack,
Special cylinder 5 and small ball 6 are placed on pressure film 7 and cushion compound 6, there are certain with upper fixed pan 3 for small ball 6
Gap, load cell display 9, hydraulic pump 1, control valve 2 are connected with hydraulic jack 8.
It is simple in structure to demarcate test device, the pressure film of various specifications can be tested.
Pressure film and special cylinder need to be placed on hydraulic jack upper surface center, prevent from sending out when experiment
It is raw to tilt.
Cushion compound is placed between pressure film and special cylinder, ensures that pressure film is not contaminated.
Installed load sensor in hydraulic jack, and pass through load transducer display monitoring pressure in real time value.
Upper fixed pan is contacted with small ball, makes cylinder and jack contact position uniform force.
Pressure is repeatedly measured under same pressure value carries out analysis comparison.
The test method of the present invention, implements according to the following steps：
Before experiment, by hydraulic jack between lower fixed pan and upper fixed pan, and kept with upper fixed pan
A certain distance, placement force film, cushion compound, special cylinder and small ball, and there are a small amount of gaps；Hydraulic pressure thousand
Jin top upper surface is sequentially placed pressure film, cushion compound, special cylinder and small ball.
On-test, opens hydraulic pump, moves up hydraulic jack by control valve, small ball is made to encounter fixed pan, sees
Load transducer display is examined, specified pressure value is reached, stops control valve operation, continues 20s；Adjusting control valve declines hydraulic pressure
Jack, take out pressure film, read pressure value, and with load transducer display show value comparative analysis.Same pressure value
It tests in triplicate, takes five groups of data, compared and analyzed after the completion of experiment.
Apparatus of the present invention good compatibility can not only be demarcated to applying pressure value, but also can be to different size pressure
Power film is demarcated, simple in structure, and convenient test, range are wide, is equally applicable to other pressure test products.
