Hydraulic hose performance test experiment table

Abstract

The invention relates to a hydraulic hose performance test experiment table mainly comprising an electric control system, an impact load system, a bending driving system of a hose to be tested, and anenvironmental simulator which are connected mutually, wherein the impact load system mainly comprises a hydraulic oil pump I, an unloading spillover valve, an accumulator, a two-position four-way magnet valve, a throttle , a pressure booster, a stop valve, a counterbalance valve, an oil return filter I, a pressure gauge, a pressure sensor, an oil tank, a connection oil pipe, a joint, and the like; the bending driving system of a hose to be tested mainly comprises a hydraulic oil pump II, a safety valve, an oil return filter II, a three-position four-way magnet valve, a hydraulic oil cylinder,a connection oil pipe, a joint, and the like; and the environmental simulator mainly comprises an environmental chamber body and an electric heater, an ultraviolet emitter and a bending degree controller of a hose to be tested, which are arranged in the environmental chamber body. The experiment table can test a plurality of hoses simultaneously, test the experimental pressure wave shape of the hoses to be tested on line and estimate the fatigue lifetime of the hoses to be tested; and the invention has simple structure, easy operation, little energy consumption and high reliability.

Description

technical field [0001] The invention relates to a hydraulic hose performance test bench, which is especially suitable for the reliability assessment of hydraulic hoses in mechanical vehicles, or for investigating the impact pressure resistance, fatigue life and environmental adaptability of hydraulic hoses in other mechanical equipment . Background technique [0002] Hydraulic hoses are widely used in hydraulic systems of various mechanical equipment due to their excellent flexibility, but due to their special working conditions and environments, such as frequent changes in shape, high oil pressure, high oil temperature, , even by strong ultraviolet radiation, etc., are prone to fatigue damage, which seriously affects the reliability of mechanical equipment and the safety of self-propelled mechanical vehicles. Therefore, it is very important to conduct reliability assessment on hydraulic hoses. At present, there is still a lack of effective comprehensive performance evalua...

AI Technical Summary

Problems solved by technology

At present, there is still a lack of effective comprehensive performance evaluation methods for hydraulic hoses for this special use requirement. On the one hand, the existing experimental equipment consumes a lot of energy and the cost of experiments is high; on the other hand, it does not consider the working conditions of hydraulic hoses. and the particularity of the use environment, the test data obtained from it is difficult to reflect the objective reality
