YZ series electronic hydraulic pillow force measuring hydraulic pillow pressure box

  YZ series electronic hydraulic pillow force measuring hydraulic pillow pressure box
YZ series electronic hydraulic pillow, electronic hydraulic pillow, force measuring hydraulic pillow, pressure box
YZ series electronic oil pressure pillow is a portable pressure measuring instrument suitable for mines
It is mainly used for ground pressure observation
It is a flat box welded by two thin steel plates of the same shape
Its shape and size depend on the service conditions
YZ series electronic hydraulic pillow has the advantages of simple structure, small size, easy processing, general material and light weight

1、 YZ series electronic hydraulic pillow parameters:
Range: 0-60Mpa
Resolution: 2MPa ,
Accuracy: 1
6% FS
2、 YZ series electronic hydraulic pillow structure:
The force transfer plate directly bears the pressure of roof rock stratum
The pressure is transmitted to the pillow body pressure box and the hydraulic pressure in it increases gradually
The hydraulic pressure is measured and read by the pressure sensor
The deformation of the pressure sensor is measured by connecting the wire to the resistance strain gauge through the elastic diaphragm
The oil in the pressure box is filled by the oil filling hole
The pressure box is formed by die forming of the upper cover plate and the lower cover plate
The mounting hole and oil filling hole of pressure sensor have reliable sealing performance and correctly transmit rock pressure

3、 YZ series electronic hydraulic pillow classification:
YZ series electronic oil pressure pillow can be divided into two categories according to its purpose:
1
Loading hydraulic pillow is a flat iron box, also known as hydraulic pillow or flat jack, which is filled with oil by high-pressure oil pump and loaded on the tested object

2
Force measuring hydraulic pillow is also called pressure box
It differs from the loaded pressure pillow in that it has a pressure balance chamber
When the hydraulic pillow bears external pressure, the pressure will push the metal film to tightly plug the oil inlet and outlet
During the test, the micro oil pump is used to pump oil to the oil inlet pipe
When the oil pressure reaches the measured pressure value, the metal film is in equilibrium
At this time, the reading of the pressure gauge is the external force value
