Abstract

The invention discloses an impulse test system of a hydraulic hose. The system comprises a hydraulic impulse loading system and the like. The hydraulic impulse loading system comprises an oil source and the like. The oil source comprises a main oil tank and the like. The main oil tank is respectively connected with a hydraulic pump and an overflow valve. The hydraulic pump is connected with a one-way valve I which is respectively connected with a hydraulic control valve, an electro-hydraulic servo valve, a pressurizing cylinder and an energy storage device I. The electro-hydraulic servo valve is connected with the hydraulic control valve, and an energy storage device II, the hydraulic control valve and a tested hydraulic hose connecting block I are connected with the pressurizing cylinder. The pressurizing cylinder, the electro-hydraulic servo valve, the hydraulic control valve and the overflow valve are connected with the main oil tank. A temperature control system comprises a throttling hole, a one-way valve II, a high temperature oil tank and a radiator. A tested hydraulic hose connecting block II and the radiator are connected with the throttling hole. The radiator is communicated with the high temperature oil tank. A one-way valve II is connected with the high temperature oil tank, and the one-way valve II is communicated with the tested hydraulic hose connecting block I. The electro-hydraulic servo valve is connected with a controller.

Description

technical field [0001] The invention relates to a hydraulic hose test system, in particular to an energy-saving hydraulic hose pulse test system capable of high temperature tests. Background technique [0002] Hydraulic hoses are widely used in hydraulic systems. During the operation of the hydraulic system, hydraulic hoses are often damaged or failed due to hydraulic pulses or heat. Therefore, the hydraulic hoses are tested to simulate various hydraulic pulses and high temperature phenomena in actual working conditions. For It is of great significance to ensure the safe operation of the hydraulic system. At the same time, because the hydraulic hose pulse test involves a high-pressure, large-flow hydraulic loading system, the current hydraulic hose pulse test system generally consumes a lot of energy and is expensive, which is very unfavorable for popularization. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a hydrau...
