Technical field
The utility model relates to automobile pipeline testing apparatus field, is specifically related to a kind of novel pressure impulse testing machine.
Background technology
Pressure pulse test machine in existing technology can only carry out the pulse test of dynamic and static state at single temperature (normal temperature) to automobile pipeline, cannot pressure and temperature in Reality simulation environment for use, and therefore, test result reliability is poor.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of novel pressure impulse testing machine, by setting up humiture environmental cabinet, making the temperature and pressure inside and outside automobile pipeline all adjustable, realize simulating practical service environment accurately to test, improve the reliability of test result.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of novel pressure impulse testing machine, comprising pressure pulse reservoir and PLC control system, also comprising the humiture environmental cabinet for placing sample; Heating system is provided with in described pressure pulse reservoir; Described pressure pulse reservoir is connected with sample by output channel, and the output channel outside described humiture environmental cabinet is provided with increase valve, and the output channel in described humiture environmental cabinet is provided with tensimeter; The opposite side of described sample is connected with the forcing pump in described pressure pulse reservoir by input channel, and described pressure pulse reservoir is provided with freeing port; Described PLC control system is connected with described heating system, described increase valve, described tensimeter and described forcing pump electric signal respectively.
Preferably, be provided with temperature sensor near input channel one end of described sample, described temperature sensor is connected with described PLC control system electric signal.
Compared with prior art, the utility model has the advantage of:
This test macro is not traditional single static state, spins pressure test macro dynamically; More that simulation is tested in the application feature of reality.As simultaneously can also the temperature in control tube and the surrounding environment (humiture) outside pipe except the pressure in control tube; The more suitable environment in conjunction with reality carrys out simulation test, and dirigibility is strong, and cost is low, has manually and automatic two kinds of operator schemes.
Test macro endurance life of our automobile pipeline, is mainly used in simulating the life-span property test being in pipeline under High Temperature High Pressure for a long time.Native system except adopting conventional pressurization more combination product test under the application conditions of reality, the environmental unit had now and press device are incorporated into one by us, can test accordingly under different ambient temperature and humidities by simulated automotive pipeline, simultaneously can also according to different using states, carry out the static pressure that continues or dynamic pressure; Tired resistance to durability test at heating system can also be used under special condition to make the temperature in pipe be in 135 DEG C ± 5 DEG C for a long time.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment, the utility model is described in further detail.
Embodiment 1.
As shown in Figure 1, a kind of novel pressure impulse testing machine, comprises pressure pulse reservoir 1 and PLC control system 2, also comprises the humiture environmental cabinet 3 for placing sample 4; Heating system 5 is provided with in pressure pulse reservoir 1; Pressure pulse reservoir 1 is connected with sample 4 by output channel 6, and the output channel outside humiture environmental cabinet 3 is provided with increases valve 7, and the output channel in humiture environmental cabinet is provided with tensimeter 8; The opposite side of sample 4 is connected with the forcing pump 10 in pressure pulse reservoir by input channel 9, and pressure pulse reservoir is provided with freeing port 11; PLC control system 2 respectively with heating system 5, increase valve 7, tensimeter 8 and forcing pump 10 electric signal and be connected.
Be provided with temperature sensor 12 near input channel one end of sample 4, temperature sensor 12 is connected with PLC control system 2 electric signal.
This test macro is not traditional single static state, spins pressure test macro dynamically; More that simulation is tested in the application feature of reality.As simultaneously can also the temperature in control tube and the surrounding environment (humiture) outside pipe except the pressure in control tube.
Native system test time can setup parameter scope as follows: the temperature in pipe 85 DEG C-150 DEG C, the temperature outside pipe-40 DEG C-180 DEG C, pressure 0.1bar-0.5bar, humidity 25%R.H-98%R.H.The parameter of often setting in testing: 135 DEG C, inside, outside temperature 85 DEG C, pressure 0.2bar, humidity 50%R.H.
Native system our vibrational system supporting can also do some pressure vibrations in the torture test of one, i.e. additional a set of independently vibroseis on basis of the present utility model except doing single pulse testing.When doing vibration test, vibrational system substitute original pressure pulse reservoir (i.e. pressure pulse test machine) and humiture environmental cabinet with the use of.Utilize the compression system of pressure pulse, measured piece is placed on vibration table together with test fixture, so just can fatigue life test under the combined action of the vibration suffered in actual motion of some pipeline of simulated automotive and pressure.This equipment more combines actual suitable environment and carrys out simulation test, and dirigibility is strong, and cost is low, has manually and automatic two kinds of operator schemes.
The logical pressure pulse test of century China, requires: high temperature (135 ± 5) DEG C in pipe strictly according to the facts; Pressure 0.2bar; Environment temperature: the test carrying out 2000h under the condition of 85 DEG C.
Test macro endurance life of our automobile pipeline, is mainly used in simulating the life-span property test being in pipeline under High Temperature High Pressure for a long time.Native system except adopting conventional pressurization more combination product test under the application conditions of reality, the environmental unit had now and press device are incorporated into one by us, can test accordingly under different ambient temperature and humidities by simulated automotive pipeline, simultaneously can also according to different using states, carry out the static pressure that continues or dynamic pressure; Tired resistance to durability test at heating system can also be used under special condition to make the temperature in pipe be in 135 DEG C ± 5 DEG C for a long time.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
