First, the conditions of use of equipment: 1, the device can be normally installed at the demand side of the case without having to increase the use of other facilities. 2, maneuvering time: 7.5 hours × 3 classes / day × 250 days / year = 5625 hours / year 3, ambient temperature: -5 ℃ ~ 42 ℃ 4, test media: When room temperature water (temperature below 0 ℃, pressure test media should be antifreeze) 5, the design pressure: with the user requirements, any user with the test pressure. 6, the test temperature: room temperature 7, the pressure measurement accuracy: thousandth of full scale accuracy. The system uses precision sensors for FS 0.1%. 8, the overall accuracy of the present control system is FS 0.3-0.5%. 9. Power: AC380 / 220V, 50Hz 10, Altitude: ≤1500 m; 11, relative air humidity requirements: ≤70-90%; two, the main function of this set of equipment reference customer technical requirements of non-standard production. Which referenced test pump to perform standard: JB / T9089-1999 test pump JB / T53194 electric test pump product quality grading GB-T9234-1997 GBT 7784-2006 reciprocating pump motor motorized three reciprocating pump test method, a portable recording Miriam pressure acquisition system consists of: digital recorder (color), micro dot matrix printer, an accuracy of one-thousandth of a full-scale pressure transmitters and portable chassis components. Note: Portable Recorder pressure collection system functions can be non-standard custom. These features just mentioned, for reference only, please prevail in kind. Digital recorder pressure Technical Data Acquisition System: Digital Recorder five inches (color), AC220V power supply, access to the pressure sensor signal; acquisition of pressure data can be exported to import computer through U disk, can also be directly connected to the computer via the computer PC software reads data; micro-printer (needle); pressure sensors: full scale accuracy FS0.1%, DC24V, 4-20MA, with user requirements, can be any user with the test pressure; instruments Toolbox: Installation recorder and printer etc, standard; Portable Chassis: placement instrument kit and spare parts; instrument power cord: a; pressure signal line: set; 8G high speed U disk: a; Computer PC management software: CD-ROM. Portable Recorder pressure acquisition system has the following features: 1, the pressure test, the pressure value can be displayed in real time and real-time pressure curve, automatically record pressure and boost curve packing process and store mini-printer to print to, or Export data to a computer through U disk function. 2, the digital recorder pressure collection system at any time via the data lines directly connected to the computer (laptop), real-time observation by computer background software test case and pressure values ??and pressure curves, and import data through the computer at any time to print the test reports, Test report formats can be any electronic files edited at any time. Computer (laptop) is provided by the customer. 3. Remote Control: Portable Recorder pressure by the pressure sensor data acquisition system connected to test pump line can be extended in order to achieve remote control, safe pressure testing purposes!
