Performance Testing

The performance testing of 320D injector and spare parts includes electrical characteristics, accuracy, the tolerance of high temperature, low temperature, pressure as well as leakage, durability and others working conditions testing. These conditions of each 320D injector and spare parts will be tested before our 320D injector and spare parts are sent to customers.

Above are the tests needed to be done after the 320D injector and spare parts are finished producing. However, regular checking also very important to keep the 320D injector and spare parts perform well.

In order to make sure the 320D injector and spare parts works normally, there are some parts of 320D injector and spare parts needed to be checked regularly and before installing to 320D injector and spare parts.

① Check whether there is deformation, cracking, thread damage, quenching, leakage and rust in the guide sleeve, spring, gasket and tight cap of the 320D injector and spare parts. The tight cap of the 320D injector and spare parts must be replaced after being disassembled for more than 5 times, as shown in the following.

② Replace the tight cap of the 320D injector and spare parts and the copper gasket of the 320D injector and spare parts.

③ Check whether the gap between the 320D injector and spare parts needle and the 320D injector and spare parts shell is within the standard range and whether it reaches the standard for use

④All parts should be examined for wear under a microscope at least 20 times larger

⑤ 320D injector and spare parts tight cap deformation, cracking, thread damage, quenching, leakage, will lead to black smoke vehicle cap, 320D injector and spare parts damage.

⑥320D injector and spare parts opening pressure greater than or less than the specified range may cause 320D injector and spare parts damage.
⑦ Failure to replace wearing parts in time during maintenance may lead to 320D injector and spare parts damage.

These are some precautions you need to know to maintain an 320D injector and spare parts. If there are more questions about 320D injector and spare parts and other problems, you are welcomed to contact us, 320dinjector.com will do the best to help you solve your problems.
