High pressure common rail injector tester, its function is to imitate the diesel Engine ECU (Engine Control Unit) principle, provides high pressure oil for high pressure common rail injector assembly, at the same time provide Bosch, denso, Delphi and other common rail system Control signal, drive the high pressure common rail injector, used to detect diesel Engine high pressure common rail injector assembly of sealing, the atomization quality, jet flow and the oil return amount, the solenoid valve open and shut case, is the most simple, the performance and the ideal test equipment.
A: the features and USES
The characteristics of high pressure common rail injector tester is pressure rise speed, good stability, storage capacity, injection time is long, simple and reasonable structure, convenient operation;
Main inspection such as Bosch, denso/Delphi and general diesel engine high pressure common rail injector fuel injector, at the same time to test common rail injectors injection flow rate and oil amount back.
2: technical parameters
Try a, maximum pressure: 32 mpa
B, control high pressure common rail injector apparatus (can choose Bosch Bosch, Denso unit, Denso, Delphi, Delphi, such as fuel injector)
Range of pulse width: 100 ~ 3000 us
Frequency range: 1 ~ 30 hz
Technology range: 1 ~ 3000 times
C, pressure gauge measuring range: 0 ~ 60 mpa
D, working voltage: 220 v
E, the total weight: about 50 KGS
F, shape size:
W380 L470 * * H720mm
Attention 3: before use
A, install the detector using bottom hole is fixed on the stable job
B, the work environment must be clean and experiment, the operator's hands must be clean
C, will precipitate 48 hours of pure diesel 0 # or - 10 through the filter to join the mailbox, do test does not conform to the requirements of diesel oil is strictly prohibited
D, with reference to the use of high pressure common rail injector test bench manual injection parameter set to standby.
4: concrete operation
A, according to the common rail injector model and the connection of different size, please select A respective injectors corresponding clamp connection good, into the corresponding to the clamping device and fixed well. When measuring the atomization quality and the sealing experiment, the nozzle insert around 20 mm in organic glass; When test oil and oil return quantity, loosen the pillar to handle, insert nozzle into oil screw press tight introversion, ensure that O ring seal is good, the pillar to handle lock.
B, open the high-pressure oil switch, pressure oil pump handle, when the pressure rose to 25 ~ 30 mpa moment to stop pump oil.
C, and then through the operation of high pressure common rail injector control instrument to check fuel injector; There are the following:
A, the quality of atomization, and electromagnetic valve open test
B, the fuel oil and back to check
C, check out, you should close the high-pressure oil switch, unload connected to the injector inlet high-pressure tubing
(note: Ken will have a small amount of overflow), can be completed.
Please read carefully before use injector control instrument machine monitor instruction manual, strictly pay attention to safety matters, right, in accordance with the operation procedures, proper use and maintenance of equipment, to ensure that equipment normal work safety (experimental pressure 20 mpa ~ 30 mpa).
