Instantly, injection type mortar strength detector is widely used in masonry mortar inspection, and measurement and calibration demand is huge, and state
The device of interior uniform type not yet calibrates its indicating value.
The calibration method used domestic at present is mostly and to process U-shaped frame accessory using electronic material testing machine,
20mm is pressed downward when pressure head of testing machine and injection rod end face contact and records final force value.Firstly, the testing of materials
The accurate level of machine is relatively low, wherein highest is 0.5 grade, the limit error that represent corresponding force value and displacement should be low
In ± 0.5%, and referring to the content in relation to calibrating standard, actual error parameter should be controlled ± 1%, will even be owned
Error problem foreclose, standard and by the limit error between test examination instrument be also required to lower than triplication pass relationship；Secondly,
General testing machine clamping attachment not corresponding with penetrometer, this may influence calibration result and bring insecurity factor；Again
It is then affected to measurement result whether determining that its contact is artificially observed in contact and for reach ideal contact conditions right
Testing machine is largely operated, because meaning that penetrometer spring is compressed when showing force value on testing machine, works as test
Force value is shown as further meaning that testing machine is not yet contacted with penetrometer when zero on machine, this non-contacting experimental condition like contact
The repeatability that will lead to measurement result is larger；Finally, due to the tension and compression characteristic of spring meets Hooke's law, and the compression of spring with
Displacement must be on the same axis, that is to say, that the two must be coaxial, but testing machine cannot make the two due to designing at present
It is absolutely coaxial and there are deviations, so that the related coefficient of linear equation becomes very big.In recent years, for penetration type, for injection
Formula mortar strength investigating instrument also has a small number of relatively professional calibrating installations, structure mostly use force value sensor, displacement sensor,

The injection type mortar strength inspection of the type and Liaoning Institute of Metrology's autonomous Design of the design of Shuai Qi Electrical Appliances Designing Co., Ltd
Survey instrument calibrating installation.This calibrating installation manual loading, automatic detection level is low, and trigger cannot be certainly in the detection process for penetrometer
It moves hook and restarts device only manually again to terminate detection process back to initial position, cause detection efficiency
Lowly；Furthermore the calibrating installation can only measure the displacement under force value and fixed force value under fixed displacement, be unable to measure practical work
The force value of trigger release moment, displacement under condition, and since the emergency case occurred in detection process easily leads to the damage of calibrating installation
It is bad, the especially damage unrepairable of force value sensor and displacement sensor, therefore, it is necessary to have can accurate controlled speed servo
Motor and emergency stop device, to realize the safe and reliable of detection process.A kind of injection type mortar strength detector is provided hereby
