FIELD: machine building.
SUBSTANCE: invention relates to machine building and is intended for process equipment explosion protection, in particular, protection against destruction during rupture disc explosion by combustible mixture. Explosion-proof membranes analysis plant comprises explosion vessel, in which explosion of combustible mixture is carried out, membrane attachment assembly installed in explosion vessel seat parallel to its axis and in vessel end section closed by protective screen. In vessel end section closed by protective screen, pressure mechanical indicator with indicator motor switch-on selector is arranged parallel to said membrane attachment assembly. Explosion chamber is arranged coaxially and opposite to vessel end part closed by protective screen, and has unions for venting said vessel after experiment. In explosion chamber end section coaxially with it, an ignition plug is arranged, having ignition actuation push-button brought-out from explosion chamber inner part. Combustible fluid filling union with the plug is secured at vessel wall, above ignition plug terminals. Said venting unions are equipped with vents to inhibit blow-out of combustible mix blast products. Test working components include: pressure indicator, ignition plug, combustible fluid filling union, unions for venting explosion vessel by “rupture” strength, exceed tested membrane strength for not less than two times. In said vessel end part a pressure sensor is installed, which output is connected to pressure signal amplifier, signal from which comes to computer, in which it is recorded and pressure signal output on computer display. Safety screen is made sealed in form of cup fixed in vessel end part so, that cup bottom is located opposite to membrane attachment assembly. Safety screen is made of armor-piercing translucent material.
EFFECT: higher efficiency of process equipment protection from explosions due to increase in membrane assembly high-speed operation and reliability of its operation.
