Pulse test bench and pressurizer

Abstract

The invention relates to a high-pressure flexible tube pulse test bench, and also relates to a pressurizer which is specially used in the high-pressure flexible tube pulse test bench. The purpose of the invention is to provide a pulse test bench which can really imitate a real fluid and can realize a sine wave and a high frequency. A technical scheme for realizing the purpose of the invention is characterized in that: the pulse test bench comprises an electric control cabinet, a cold liquid storage device, a cold liquid pumping device, an energy storage device, a conversion valve and a pressurizer; hydraulic oil which is pumped from the cold liquid storage device to the energy storage device by the cold liquid pumping device enters the pressurizer through the conversion valve; and the hydraulic oil which is pressurized is accessed to a pulse test port. The pulse test bench is characterized in that: the pulse test bench which is between a primary energy storage device and the conversion valve is connected with a secondary energy storage device through a flexible tube, and the conversion valve is a servo flow valve; the cylindrical oil is mixed with a heated liquid from a heated liquid pumping device before the outlet end of the pulse test port; the oil return port of the pressurizer is connected to the cold liquid storage device; and the electric control cabinet controls the opening and the closure of all valves according to program requirements.

Description

technical field [0001] The invention relates to a pulse test stand, in particular to a hose pulse test stand with high pressure. [0002] The invention also relates to a supercharger; the supercharger is specially used in the high-intensity pressure hose pulse test bench. Background technique [0003] Generally speaking, the pressure of the hose pulse test bench in the existing technology is not high, and often cannot really meet the actual requirements; for the existing technology on the market, there is also a problem, such as the imitation of the working environment , there are differences in the existing technology, because in actual work, because the pipe fittings are likely to work in a certain heat environment, the liquid in the pipe fittings may also have a certain temperature; while the current technology only imitates the pressure, Create sine waves, etc. [0004] For high-strength pressure, the pressure is too high, few people use hoses, and the pressure is very...

AI Technical Summary

Problems solved by technology

[0005] The waveforms made by the experimental benches that appear in the market are all rectangular waves or trapezoidal waves, because the control of this method is quite simple, as long as the switching control of the switching valve is enough; and how can the liquid fluid in real life go away? Rectangular wave or trapezoidal wave, the real liquid fluid should be a sine wave, and the frequency should be quite high; for the existing technology in the market, the sine wave cannot be achieved, and the speed is at a frequency of five Hz
