Pressure simulation test device

Abstract

The invention discloses a pressure simulation test device. The device comprises a rack and a support; a vibration exciter which is inverted is arranged on the rack; the vibration exciter comprises a shell and a moving coil; the moving coil is connected with the shell through a plurality of elastic connectors; the moving coil is internally provided with a hollow connection rod; a pressure sensor isarranged at the bottom of the hollow connection rod; a displacement sensor is arranged at the top end of the hollow connection rod; the support is arranged below the vibration exciter; a jig is arranged on the support; a limiting groove for containing a piston cylinder is formed in the jig; the piston cylinder is used for holding a tested fluid; the piston cylinder is internally provided with a piston rod; the upper end of the piston rod is connected with the hollow connection rod; an extrusion port is formed in the bottom of the piston rod; the vibration exciter vibrates to drive the hollowconnection rod to vibrate up and down; the hollow connection rod drives the piston rod to carry out extrusion testing on the tested fluid in the piston cylinder; and the pressure sensor and the displacement sensor are respectively used for acquiring the pressure and displacement data of the piston rod. The device is capable of satisfying the performance test demands under a high-rotation speed centrifugal state.

Description

technical field [0001] The invention relates to the technical field of high-speed centrifugal testing, in particular to a pressure simulation testing device. Background technique [0002] How to simulate the state of the action response of the test piece under the high-speed centrifugal state has always been a difficult problem in the industry. Due to the lack of domestic high-speed centrifugal testing machines, some test pieces need to be subjected to dynamic tests under high-speed centrifugation, such as the extrusion test of special fluids. Most of the existing methods use foreign high-speed centrifuges for dynamic testing. Testing is expensive. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a pressure simulation test device that can simulate a high-speed centrifuge and perform extrusion tests on fluids. It adopts the following technical solutions: [0004] A kind of pressure simulati...
