Fireproof test device and fireproof test method

Abstract

The invention provides a test device which sequentially comprises a heating device, a conveying device, a flow control device, a main combustion chamber, a combustion control device and a flow velocity control device,wherein the heating device is capable of automatically controlling the temperature of circulating hot water, and is constant in temperature and low in error; a water pump motor of the conveying device adopts a variable frequency motor and a programmable logic controller (PLC) system, so that the flow speed, the flow and the pressure of the circulating hot water can be controlled to be constant in the test process; the combustion control device can be used for adjusting the mixing ratio of propane gas and air by an adjusting device, and generating the flame with the temperature of 800+/-50 DEG C; the temperature of the flame is recorded and automatically stored by an automatic temperature measurement recorder; the temperature fluctuation is low, the structure is simple, and the energy is saved. The whole fireproof test device is compact in structure, reasonable in layout, low in manufacturing cost, high in degree of automation as well as convenient to operate and use.

Description

technical field [0001] The invention relates to the technical field of rubber hose assembly test equipment, in particular to a self-controlled high-temperature flame combustion test equipment and a test method. Background technique [0002] The hose assembly required by international standards for offshore oil drilling and development equipment should have fire resistance when operating (such as: under the influence of envisaged working pressure for sealing) and be able to determine the fire resistance of the hose assembly time. Therefore, it is necessary to simulate the combustion flame in order to cope with the actual fire, so as to determine that the hose assembly should have no leakage and can work normally after continuous combustion for 30 minutes at a flame temperature of 800±50°C, so as to ensure that the drilling platform has sufficient rescue or Emergency preparation time to ensure the safety of personnel and equipment and property safety. [0003] Since the fire...

Problems solved by technology

[0003] Since the fire test equipment needs to be able to automatically control the flame combustion temperature, automatically record, and automatically maintain a constant test pressure, it has a high degree of system integration requirements. At present, the major domestic test institutions and manufacturers do not have ready-made fire test equipment that meets the test requirements. Therefore It is not possible to carry out fire-resistant and flame-retardant tests in accordance with the ISO15540-2001 "Test Method for Fire Resistance of Ship and Offshore Technology Hose Assemblies" in China, which restricts the technical development of high-pressure fire-resistant and flame-retardant rubber hose assemblies for my country's marine engineering equipment industry
