I. Overview: SY-B electric waterproofing membrane impermeable is used to detect petroleum asphalt and bitumen membrane elasticity full impermeability of the instrument, which can meet the test requirements specified in GB / 328-2007. And suitable GB18173-2006, JC-7974-2005, GB12952-2011 standards. The instrument uses an electric pump pressure available to the research, construction, production, design and teaching departments. This product uses electrical automatic control filling pressure, automatically maintain pressure, digital timer, for linoleum and waterproofing membrane impermeability testing, testing and research provides a very handy device. In the case of the test pressure is less than 0.6Mpa, you can use this instrument for the measurement of other relevant material permeability or permeable. Second, the technical parameters: 1, Power: 220V 50HZ 2, the test pressure: 0-0.6Mpa 3, can specimen count: 3 (a) 4, specimen size: 150mm × 150mm 5, permeable plate inside diameter: Φ92mm 6, Test the water temperature: 20 ℃ ± 5 Third, use: 1, according to test requirements prior to use of specimens to gauge adjusted. Adjustment method is: the middle of the gauge glass Mongolia has adjustment knob, its upper limit and lower limit adjustment value, need the help of a slotted screwdriver. The cap is screwed onto the pointer position of the test pressure of a predetermined number, the lower limit smaller than the upper limit pointer 0.05Mpa screwed into position, so that during operation when the pressure to meet the requirements (the upper limit) stops automatically pressurized. When leaks or flooding the pressure drops to a certain value (lower limit) pump and automatically start to add pressure. For example: test pressure requirements 0.3Mpa, the case of the upper middle of the circle dial pointer is in position 0.3, with a screwdriver to tighten the middle of the lower limit of 0.25 pointer position. 2, when used, first with 2.60-handle three permeable disc release pressure ring removed, the water inlet cap unscrewed, then drain valve locked, slowly into the water from the water inlet to the vessel two-thirds of place, respectively, unscrew the valve "1", "2", "3" (0 for release valve) in the middle of the water holes out water, overflowing permeable plate stops, then tighten the water inlet cover. 3, the test piece was placed on a permeable plate ring apron, then the specimen is placed on the platen test piece, tighten the screws. 4, according to the testing requirements set time dial code, set the time value. 5, plug in the power cord, turn the start switch, the pump began to inject the gas pressure inside the container, then the pressure indicator light. 6, to automatically stop the pressure on the pressure limit, then the constant pressure indicator light, according to the specified time after completion of the test, twist open the valve, release the water pressure relieved, and then release the pressure ring remove the specimen, the test is completed. Fourth, note: one, each completed test, each piece should permeable disc clean, apply anti-rust oil. 2, when the pressure go up, you should check whether all parts of leaks or leaks place, NC Time Relay Usage: The instrument has four digital, maximum delay control range 0-9999 minutes to set automatically after 3 hours Stop an example: the dip is set to "0180" and then power on start automatic timing, compressor automatic pressure, constant pressure in the process, maintain, was reached three hours off automatically, the compressor stops working, At this point if you want to start the compressor again, press one F cleared to enter into the next test.
