System for controlling high-flow water flow of centrifugal machine

Abstract

The invention relates to a system for controlling the high-flow water flow of a centrifugal machine, which is characterized in that water storage tanks are outdoor large-volume water storage tanks arranged in high positions. The system is internally provided with a water holding ring which is an annular water channel; the annular water channel is arranged around a large-arm rotating shaft of the centrifugal machine, and the annular water channel and the centrifugal machine are arranged concentrically and rotate together; the water in the large-volume water storage tanks is injected in to the annular water channel through water pipes; the water outlet of the annular water channel is connected with a model box of a centrifugal model through a pipe; a water injecting pipe of the annular water channel is internally provided with a control valve; a connecting pipe between the water outlet of the annular water channel and the model box is internally provided with a flow meter; the output of the flow meter is connected with a control computer; and the control computer is used for controlling the opening degree of the control valve. The system is fixed on the ground water supplying pipe and is not in hardware contract with the water holding ring which rotates at high speed, thus the problems of friction and leakage are avoided. Control valves can be controlled to discharge the water with a set flow value, and the water can be directly injected into the water holding ring.

Description

technical field [0001] The invention relates to a test device applied to a centrifuge, in particular to a device for a large-flow water flow control system of a centrifuge, which is especially suitable for an earth-rock dam failure centrifugal model test system for carrying out research on a centrifugal model test of an earth-rock dam failure failure , that is, to provide continuous and large flow of water under the condition of high-speed operation of the centrifuge, so that the models of homogeneous dams, core wall dams and face dams encounter severe events such as water overflow or dam body piping, so as to study their collapse process and failure mechanism . For structures such as river embankments that are easily damaged by water erosion, or that are related to water level fluctuations, the system device can also be used to simulate test water flow and carry out centrifugal model test research. Background technique [0002] Reservoir dams bring huge economic and social...

Problems solved by technology

The optimization scheme of the present invention will also solve the following problems at the same time: (1) add a suitable water flow control system to the original centrifuge system, and this system should be able to continuously provide sufficient water to erode the dam body during the dam break test; ( 2) Set up an advanced data and image acquisition system to measure the flow process of the breach of the dam and capture and record the entire process of the collapse of the earth-rock dam from multiple angles; (3) The water flowing out of the outlet cannot damage the foundation pit of the centrifuge and can Discharge in time; (4) The system can work normally under the condition of high centrifugal acceleration and high-speed debris flow
