Background technology
Seal is the packoff of hydraulic pressure, pneumatic element, is widely used in the places such as national product every field and Aeronautics and Astronautics engineering and urban construction.Current domestic seal manufacturer is to entrust the test of installing of seal applying unit substantially.This test model, the cycle is long, expense is high, the authenticity of result is poor, and the cross matching that completes limiting velocity and ultimate temperature is more difficult.
This seal research and development pattern at home airtight industry of liquid exists for many years, is unanimously perplexing seal production unit.Do not having under the research and development condition of testing equipment, want to carry out the breakthrough of properties of product, extremely difficult, and high experimentation cost, long test period, the poor result of confidence level, the research and development of products that makes a lot of seal company is just with colleague's back abroad, realizes that to surmount be almost possible.
Summary of the invention
The invention provides a kind of seal testing equipment, to solve the problems of the technologies described above.
The present invention is mainly grouped into by hydraulic system, electrolyte control part, test-bed, electrical control division, hydraulic system is mainly comprised of high-low pressure ram pump, electro-hydraulic reversing valve, pressure-display device, temperature control system, fuel tank, and high-low pressure ram pump, electro-hydraulic reversing valve, pressure-display device, temperature control system, fuel tank are connected respectively by oil pipe; Electrolyte control part is mainly comprised of ultra-high pressure solenoid valve, intelligent pressure transmitter, and ultra-high pressure solenoid valve, intelligent pressure transmitter link together by integrated package; Test-bed is mainly comprised of composite hydraulic cylinder, stand, and composite hydraulic cylinder is bolted on stand; Electric control system is mainly comprised of operator's console, instrument, A.C. contactor, relay, and instrument, A.C. contactor, relay are installed on operator's console; Hydraulic system links together with electrolyte control part, test-bed respectively by oil pipe, and electric control system links together with hydraulic system, electrolyte control part respectively by control line.
The present invention is the type approval test equipment of hydraulic cylinder, cylinder seal part, and easy to use, the cycle is short, and production efficiency is high, and power attenuation is low, labour intensity is little; Owing to adopting mechanical-electrical-hydraulic integration design, automaticity is high, and process of the test participates in without personnel, without interference from human factor, has guaranteed the accuracy of experimental result.

In figure: 1 hydraulic system, 2 electrolyte control parts, 3 test-beds, 4 electric control systems, 5 high-low pressure ram pumps, 6 electro-hydraulic reversing valves, 7 pressure-display devices, 8 fuel tanks, 9 temperature control systems, 10 integrated packages, 11 intelligent pressure transmitters, 12 ultra-high pressure solenoid valves, 13 stands, 14 composite hydraulic cylinders, 15 operator's console, 16 instrument, 17 A.C. contactors, 18 relays.
Embodiment
As shown in the figure, in hydraulic system 1, there is high-low pressure ram pump 5, electro-hydraulic reversing valve 6, pressure-display device 7, fuel tank 8, temperature control system 9, high-low pressure ram pump 5, electro-hydraulic reversing valve 6, pressure-display device 7, fuel tank 8, temperature control system 9 are connected respectively by oil pipe, for the various motor patterns of piston in hydraulic cylinder and piston rod provide corresponding hydraulic oil; On electrolyte control part 2, ultra-high pressure solenoid valve 12, intelligent pressure transmitter 11 are installed, ultra-high pressure solenoid valve 12, intelligent pressure transmitter 11 link together by integrated package 10, can realize impulsive control, the pressure-loaded of motion.On test-bed 3, composite hydraulic cylinder 14 is installed, stand 13, composite hydraulic cylinder 14 is bolted on stand 13, drive steady, laborsavingly, load test when can realize piston, piston rod seal component, reduces the stress of seal in hydraulic cylinder more truly.The commutation of hydraulic cylinder adopts approach switch to control, and travel position is adjustable.Electric control system 4, is provided with instrument 16, A.C. contactor 17, relay 18 controls by operator's console 15, has electric current, voltage demonstration, defencive function, test number (TN) Presentation Function.Hydraulic system 1 links together with electrolyte control part 2, test-bed 3 respectively by oil pipe, and electric control system 4 links together with hydraulic system 1, electrolyte control part 2 respectively by control line.
During test, first, the composite hydraulic cylinder in test-bed 3 14 is pulled down, then composite hydraulic cylinder 14 is taken apart, the seal that needs test is installed, then, composite hydraulic cylinder 14 is ressembled.The strict cleanliness of controlling part in assembling process, as find that there is dirt, necessarily clear up, clean.Hydraulic cylinder after assembling is arranged on test-bed 3 to connected pipes, fixation.According to testing requirements, adjust low-pressure hydraulic pump output pressure, delivery rate, high-pressure hydraulic pump output pressure, regulate temperature control system; Then, do not load operation several, the air in emptying hydraulic cylinder; By digital indicator zeroing, start start button, make hydraulic cylinder operation, load exploitation and connect, implement test.
