NALC automatic gas relay pressure relief valve test device

Also called name
Gas wire relay pressure release valve tester, wire relay pressure release valve automatic test device, gas pressure release valve test device, wire relay pressure release valve tester, gas wire pressure tester
Features Tester Features
1, NALC type automatic gas relay test bed, using the latest embedded system control technology, integrated user's actual needs and introduced a new generation of gas relay test detection system. The system uses oil pump - flow meter continuous measurement method, respectively φ25, φ50, φ80 mm diameter gas relay at home and abroad flow rate, volume and seal detection, and the experimental process without human intervention.
2, embedded PC system, the use of full-color touch display, the system can be simple and intuitive flow rate, volume, seal test-related operations, and edit the relevant test report printing, and can save the data at any time to access and print. As a result of embedded design, controlled by the PC, user-friendly, high degree of automation.
Product structure
1, the structural characteristics
(1) The external cabinet is made of cold rolling board, with the dimensions of 2400 × 650 × 1570mm (length × width × height), the total weight of the whole machine is 170kg;
(2) clamping device using a screw ratchet way to clamp the specimen;
(3) the tank is non-pressure structure, the side with a level gauge;
(4) A protective cover is provided at the installation position of the test piece;
2, electrical and control systems
(1) the working environment: -10 ~ +50 ℃, relative humidity <85%;
(2) The main electric circuit adopts AC380V, the total power is 11KW;
(3) oil pump motor with AC380V, power 5.5KW;
(4) electric actuators AC220V / DC24V power control, power 0.25KW;
(5) control system uses AC220V / DC24V power control, power 0.25KW;
(6) oil heater: AC220V, power 5KW;
(7) with 19-inch full-color touch display, full Chinese and English graphic display, the process automatically by the system, without human intervention;
(8) the use of virtual projection mouse and keyboard. This technology for the two-dimensional projection imaging, in front of the touch screen work surface, the projection of a red and the size of the keyboard consistent with the virtual projection keyboard, the operator can use the keyboard to edit the contents of the test report. Operators can also use this keyboard shortcut to complete the keyboard and mouse to switch, and through the shortcut keys on the virtual keyboard to close the projector mouse and keyboard, and then open the fixed gesture.
(9) embedded PC system can be intuitive on the heavy gas flow, light gas volume, seal detection of individual and integrated projects to operate, and at the same time edit the print test report;
(10) PC system installed by our own independent development, with full intellectual property rights of professional measurement and control software, and can implement network remote system upgrades and maintenance.
(11) Remote technical support: If the site operator needs technical support, the equipment only needs access to the peripheral network, and the remote end technical personnel can remotely control the equipment and upgrade the equipment software.
