The purpose and method of maintenance of fuel injection pump test-bed are introduced

Introduction to the purpose and method of reliability test of fuel injection pump test-bed:

In order to evaluate and analyze the reliability of the fuel injection pump test bench, the test is called the fuel injection pump test bench reliability test. The purpose of the test is usually as follows:

1. In the development stage, it is used to expose the defects in all aspects of the trial-produced fuel injection pump test rig, and evaluate the reliability of the fuel injection pump test rig to reach the predetermined target;

2. Provide information for monitoring the production process of fuel injection pump test bed in the production stage;

3. Reliability appraisal or acceptance of the test bed of the typed fuel injection pump;

4. Expose and analyze the failure rules, related failure modes and failure mechanism of the fuel injection pump test bed under different environmental and stress conditions;

5. To improve product reliability, develop and improve reliability test plan, and provide basis for users to choose products.

There are different test methods for different fuel pump test bed products, and there are various classification methods for reliability test.

1. If it is divided by environmental conditions, it can be divided into simulation tests and field tests under various stress conditions;

2. The test items can be divided into environmental test, life test, accelerated test and special test;

3. According to the purpose of the test, it can be divided into screening test, identification test and acceptance test;

4. According to the nature of tests, destructive tests and non-destructive tests can also be divided into two categories.
