The purpose of the operational performance test is to quantitatively inspect Komatsu, Kobelco,CATWait for all the systems and performance of the excavator.
Purpose of Performance Testing
1. Evaluate each function comprehensively by comparing the performance test data with standard data.
2. Based on the evaluation results, repair, adjust or replace parts as necessary to restore the performance of the machine to the required standards.
Precautions for evaluating experimental data
1. It is not only necessary to evaluate whether the experimental data is correct, but also to evaluate what scope these experimental data fall within.
2. The evaluation of experimental data must be based on the working hours of the machine, the type and condition of the working load, and the maintenance conditions of the machine.
3. Use this machine economically under optimal conditions The type of test is the host performance test, which is used to check each system, such as the engineWalking performance、Rotation performanceAnd hydraulicOil cylinder performance。
The performance of a machine does not always decrease with an increase in working hours. However, the performance of machines is generally believed to decrease proportionally with an increase in working hours. So, restoring the performance of a machine by repairing, adjusting, or replacing parts should take into account the machine's working hours.
Definition of 'Performance Standards'
1. Hydraulic component testing is used to check the operational performance of each component, such as hydraulic pumps, motors, and various valves.
2. The operating speed and size of the new machine. Performance standard 1. Operational performance of new components adjusted to technical specifications. If necessary, allowable errors will be provided. The 'Performance Standards' are listed in various tables to evaluate performance test data.
