Abstract

The invention discloses a device and a method for testing a mechanical property of a water filter pipe. The device comprises an automatic oil supply system pressure regulation control device and an expulsion device, wherein an oil supply system comprises an oil pump, an oil tank, reversing valves and the like; the extrusion device comprises a cylinder, an extrusion mold base, an extrusion mold, hydraulic cylinders, a tightening belt and the like; the oil supply can control hydraulic pipelines respectively, and can perform pressure maintaining on the hydraulic pipelines during working and perform fast unloading after working; and a replaceable conical extrusion mold base is mounted on the extrusion mold base of the extrusion device, so that the test for water filter pipes of different models is facilitated, simultaneously, a buckling device has high and low retraction and expansion speeds during working, and the work efficiency can be improved. The device and the method for testing the mechanical property of the water filter pipe has the advantages as follows: an integrated test for a confining pressure property, axial bending resistance and redial bending resistance of the water filter pipe can be realized, the applicable range is wide, the retraction and expansion pressure is large, the service life is long and the like.

Description

technical field [0001] The invention relates to a device for testing the mechanical properties of a water filter pipe, which belongs to the technical field of hydraulic machinery. technical background [0002] With the mining of deep brine, the filter pipe lengthens with the increase of water depth, whether its strength and stability can meet the requirements of deep brine mining has become the main consideration of brine mining. Under deep formation conditions, the stress state of the filter string is very complex and harsh. Many filter tubes cannot adapt to and withstand the huge comprehensive external force, which interrupts the mining operation, or even fails to resume drilling, resulting in accidents such as drilling failure. And then cause huge loss to the deep brine mining project. Therefore, obtaining real-time and reliable monitoring data of the force of the water filter pipe can provide necessary information for the force analysis of the water filter pipe. At pre...
