NL-LSQ heat pumps (air) water heater tank strength testing machine section pulsating pressure pump test bench designed for you to meet the GB / T 23137-2008 heat pump water heaters for household and similar purposes clause 6.2.3 requirements and GB-T 34786-2008 commercial or industrial and similar uses heat pump hot water 6.4.2.1 provision requirements, 24 hours of continuous work, uninterrupted test, the test schedule to meet customer requirements. Equipment using PLC central control system, the body attached waterproof protection door leaks, leak detection systems for immediate shutdown when the bladder leaks, double protection to ensure safe use of hydraulic Chong Qing, safe and reliable than the traditional use pressure testing, without continuous blasting danger. 1, the station does not carry out a test of the other heat pump water heater to be tested and the other electrical device housing spalling, retaining only the food container assembly, carried out under the rated pressure leak, the container must be sealed at the rated pressure of 100 ± 5%. 2, the test tank flat or vertically fixed container to be tested is connected to the pulse pressure test instrument pipes, pumps start testing machine, to test the water tank, fill out the air side, blocking the outlet, and adjust various test parameters such as the number of pressure testing machine to test. 3, the pulsating pressure: ambient temperature inside the vessel discharging water (except Silica copper container), the air removal within the container, according to the value of 15% (100 ± 5)% of the rated pressure of the container between the alternating plus pressure. 4. Frequency: 25 to 45 times per minute, adjustable, according to the size of the tank capacity, the greater the need for pressurized tank longer time, the number of tests per minute reduced accordingly. 5, the number of cycles: 50 million times (adjustable) 6, Power: 380V AC 50Hz 7, the working environment temperature: 25 ℃ ± 5 ℃; Relative humidity: 45% ~ 95% RH 8, pressure holding time: 0 ~ 99999S ( adjustable) 9, the maximum number of experiments: After 0 to 999999 times (adjustable) 10 per 10,000 pressurization end test machine set pressure is maintained at 1.05 times the rated pressure 10min, visual container without significant deformation, pressure 10min After the device automatically proceed following loop experiments, midway no need for staff to set it again. 11 standard pressure as two groups, namely when relief is 0.15MPa (pressure is adjustable), Paul boost pressure 0.8Mpa (adjustable pressure). 12, the test can test counts the number of tests, up to 999,999 times, 10,000 times per test dwell 10min under 0.8MPa pressure, can preset the desired number of tests, and the alarm automatically stops after the end of the experiment. 13, the device has a power-down protection, counter stops working after a power failure and automatically save data memory, but also continue to the last test next boot. 14, there is leakage protection device, the test piece rupture and leakage protection shutdown and alarm functions, lack of air protection, water protection equipment; 15, the testing process, when it detects abnormal test tank, immediately stop working and recording equipment , alarm. NL-LSQ water heater tank heater tank leak detection machine water tank leak detection machine is designed for electric water heaters, heat pump water heaters, solar water heaters, air heaters and other kinds of tanks, tank detection and design, will be placed in the interior Preparation for testing platform, do initial preparation work, after all the exact place, starting a master manipulator decline grabbed liner, accurate and grabbed preliminary positioning, promotion and sent regards inspection station, after determining the accuracy of the lock, the water began to detect After a series of timed camera, lighting, personnel and other testing, that is, whether qualified, by setting certain insurance holding pressure after detecting bladder tank tightness of leaks? Are bubbles? observe accurately the specific location of the leak test emperor robot completed a test taken back into the original water tank on tank station, while the other two will be another master manipulator station workpiece grabbed and sent workers to detect pool position detection to detect emperor workpiece manipulator 2 then back to the station platform, the workers may be further processed according to their test results, or sent to the next process, and so the cycle work. 1. Type: grab type 2, capacity: 30 single-station / hour two stations 60-70 pcs / hour Scope: a, gall diameter φ383, φ400, φ415, φ430, φ450mm (can be customized according to customer product ) b, the length L 1150-2500 mm (can be customized according to customer product) c, aperture φ52mm, φ62mm (can be customized according to customer product) d, pitch 70mm, 80mm (can be customized according to customer product) 4, the device Dimensions: Length Wide 2200 × 3000 × 3300 high power: a, Power: AC 380V, 3-phase, 50Hz b, control: AC 220V, single phase, 50Hz pressure: a, pressure: 4-5Kg / cm2 b, consumption: 150NL / MIN NL-LSQ conventional electric water heater / performance / safety and durability / energy efficiency testing machine to meet GB / T20289-2006 "water heaters" in the relevant provisions. GB_4706.12-2006 "special requirements of household and similar electrical appliances - Safety storage water heaters" relevant requirements. Conventional electric water heater / performance / safety and durability testing machine order for water, electricity, low water pressure start testing, high-pressure test, the water flow, inlet and outlet temperature of the test can determine whether the product is qualified or not, there is alarm failed test completed and then turned on safety testers, product pressure, leakage current safety performance, insulation resistance, earth resistance testing and so on. 1, each station inlet pipe into two-way: the way of the water pipe; the way for pressurized piping, each station of the installation of the pipeline a pressure regulating valve, pressure regulator to be easy to adjust with tap water temperature without control. 2, with a booster regulator system pressurized pipeline can maintain long-term 0.7MPa ± 0.02 MPa of pressure. 3, with two stations used to do the whole test, each station horizontal length: 135cm, vertical:. 80cm each station can withstand the weight of 300Kg, rigid, no deformation, can be wall-mounted horizontal position tune (one hook fixed, the other can be adjusted). 4, each station is equipped with 0.5 series ammeter (range 15A), voltmeter (range 300V). 5, each station is equipped with two 10A, 16A dual-socket and a spare is not wired outlets; into the water on the way each station to install a pressure gauge (accuracy of 0.5, the smallest scale 0.02Mpa, range 1.0 Mpa), and one each ball; each requires each station compressed air line. 6, where two stations with universal socket 16A of each one (applies to international standards UL, GS, BS, etc.); 7, with ground equipment as a whole, each station has a separate leakage protection, electrical control part of a waterproof, line to meet the total current requirements. 8, the use of stainless steel. 9, load testing client-supplied power
