High-temperature pulse test system for hydraulic hose

Abstract

The invention relates to a hydraulic pulse test system for testing the fatigue life of a hose such as a rubber pipe under high-temperature pulse pressure, and test pressure can be controlled. The system comprises an oil tank, a power device, a pulse generation device, a tested piece, a high-temperature heating device, a liquid supplementing and gas exhaust device and a leakage recycling device. The oil inlet and outlet of the oil tank are respectively connected with the oil inlet and outlet of the power device; the oil inlet and outlet of the power device are respectively connected with the oil inlet and outlet of the pulse generation device; the pulse generation device is connected with the tested piece; the tested piece is arranged in the high-temperature heating device; an oil outlet ofthe liquid supplementing and gas exhaust device is connected to the tested piece; the leakage recycling device is mounted below the tested piece; and an oil outlet of the system is connected to the oil tank of the liquid supplementing device.

Description

technical field [0001] The invention relates to a high-temperature pulse test system for hose hydraulic equipment such as rubber hoses. In particular, it relates to a fatigue life test system for hoses working in a high-temperature pulse environment. Background technique [0002] With the formulation and implementation of various standards for rubber and other hoses, a corresponding pressure pulse test system for testing hoses has emerged. Compared with the mature rubber and other hose testing technologies in developed countries, the development of various aspects in China is relatively lagging behind, the test and testing standards are not complete, and the update is slow, the development of test equipment is also relatively backward, and some even have manual debugging; compared with the slow update of domestic standards, Japan has already High temperature pulse test items are mandatory. [0003] Most domestically produced rubber hose and other hose testing systems still...
