The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 and 2, the utility model discloses a high oil pressure displacement measuring equipment, be fixed in the high-pressure cylinder 2 of base plate 1 top including base plate 1 and axial level, wear to establish piston rod 23 in the high-pressure cylinder 2, the inner chamber of high-pressure cylinder 2 is separated into antechamber and back chamber by piston rod 23, the preceding hydraulic pressure of high-pressure cylinder 2 chamber is equipped with the intercommunication and connects 211 and the back hydraulic pressure of intercommunication back chamber and connect 221, the front portion of high-pressure cylinder 2 is equipped with the pressure gauge 33 that the probe stretched into the antechamber, the front portion of high-pressure cylinder 2 still is equipped with mount 31, be equipped with displacement sensor 32 on the mount 31, the one end of piston rod 23 is passed through top cap 231 and is connected in displacement sensor 32's contact, the centre gripping has spring 34 between top cap 23 and mount. The high-pressure oil cylinder 2 has a high wall thickness and can be used under a high oil pressure of 32 Mpa. The spring 34 serves to reset the piston rod 23. When the front cavity is filled with pressure oil, the piston rod 23 is pushed to move backwards, and the displacement sensor 32 can measure displacement data; while the pressure gauge 33 can measure the change in the oil pressure. Therefore, the high oil pressure displacement measuring equipment can simultaneously acquire the pressure of high-pressure liquid oil and the displacement information of the piston rod under the condition of high oil pressure.
