Performance test device under swing condition of marine pump

Abstract

The invention belongs to the field of fluid mechanical experiments, and relates to a performance test device under a swing condition of a marine pump. The performance test device mainly comprises a swing table, the marine pump, a hydrophone, a pressure sensor, an acceleration sensor, a data acquisition instrument and a variable-frequency control cabinet, wherein the swing table comprises a swing frame, a drive motor, a speed reducer, a fly wheel, a bracket, a supporting plate, a positioning scale plate and a swing table base; the marine pump is fixed to the swing table through a foot bolt; the swing table is fixed to a cement base; and the variable-frequency control cabinet is utilized to control the drive motor, so that the swing table can be driven to operate. The performance test device can carry out external characteristic, vibration, noise and pressure pulse test under multiple working conditions, multiple angles of inclination and multiple swing periods and amplitudes of the marine pump. The performance test device is simple in structure, is convenient to mount, is wide in scope of application, is easy to operate, and is relatively high in precision, can carry out synchronous test for external characteristics, vibrations, noises and pressure pulse signals, so that effective means are provided for carrying out performance test under the inclination and swing conditions of the marine pump.

Description

technical field [0001] The invention relates to the field of fluid machinery experiments, in particular to a test device used for research on external characteristics, vibration, noise and pressure pulsation of a marine pump under the condition of tilting and swaying. Background technique [0002] Ship roll refers to the periodic angular displacement motion of the ship around the axis. A ship is a floating body on water, whether it is sailing or at anchor, it will sway and tilt with the wind and waves. [0003] Under ocean conditions, the hull will sway under the action of wind, sea waves and other factors, while the medium in the marine pump and its pipeline will generate additional acceleration and inertia force, which will cause periodic fluctuations in the working fluid and affect the unsteady flow characteristics or dynamic response characteristics, and at the same time, the force change of the marine pump operation in the swaying environment will also lead to the redu...
