By adopting the scheme, the iron ore pellet pressure testing machine is also provided with the microcomputer, so that on one hand, a test value and a time curve of the compression deformation of the pellet can be displayed; on the other hand, history can be queried.
Description
Technical field
The utility model relates to a kind of pressure testing machine, a kind of testing machine of measuring the iron ore pellets pressure intensity of more specifically saying so.
Background technology
The iron ore pellets pressure testing machine is applicable to the mensuration of iron ore roast pelletizing compressive strength.Compressive strength is an iron ore pellets suffered maximum pressure load when breaking fully.Its numerical value is the mean value of all sample measured values in one group of sample.
Existing iron ore pellets pressure testing machine comprises frame, jack unit, controll block and display, is provided with the pelletizing support on frame; Jack unit comprises crossbeam and is fixed on roof pressure piece on the crossbeam, and roof pressure piece upright position is over against the pelletizing support, and crossbeam is by screw mandrel and frame movable fixed, promptly crossbeam relatively frame move up and down, on jack unit, also be provided with pressure transducer; Controll block is electrically connected with pressure transducer, display on the jack unit respectively.During pressure testing machine work, the iron ore pellets that to measure is placed on the pelletizing support earlier, jack unit moves down, make the roof pressure piece push down iron ore pellets, continuation is pressurizeed to jack unit, break up to iron ore pellets, in the testing machine course of work, controll block shows pressure transducer maximum pressure reading on display.Have advantages such as simple in structure, easy to operate, and meet GB/T14201-93 " iron ore pellets compressive strength determination method " national standard requirement.But the deficiency that this iron ore pellets pressure testing machine exists is: the time curve that 1, can not show trial value and pelletizing compressive deformation; 2, can not enquiry of historical data; 3 can't realize improving test authenticity and public trust with remote monitoring.
The utility model content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of iron ore pellets pressure testing machine, and it can show the time curve of trial value and pelletizing compressive deformation; But enquiry of historical data; Can also realize improving test authenticity and public trust with remote monitoring.
For achieving the above object, the utility model has adopted following technical scheme: a kind of iron ore pellets pressure testing machine, and it comprises frame, jack unit and drive unit, is provided with the pelletizing support on described frame; Described jack unit comprises crossbeam and is fixed on roof pressure piece on the crossbeam, and described jack unit is connected with frame is removable, promptly jack unit relatively frame move up and down; Also be provided with pressure transducer on described jack unit, described iron ore pellets pressure testing machine is also organized into microcomputer, and described microcomputer comprises that controller, display and device store, and described microcomputer is electrically connected with pressure transducer.
Described jack unit is to connect by screw mandrel with removable connection of frame, and promptly described screw mandrel is fixed on frame, and is in transmission connection with drive unit, and described crossbeam is provided with the screw with the screw mandrel coupling, and described screw mandrel passes the screw of crossbeam.
As improvement, also be provided with displacement transducer on the described jack unit, described displacement sensor is connected with micro electronmechanical.
Adopt such scheme,, can show the time curve of trial value and pelletizing compressive deformation on the one hand because the iron ore pellets pressure testing machine is also organized into microcomputer; On the other hand can also enquiry of historical data; Can also realize simultaneously improving test authenticity and public trust with remote monitoring.
