Q1: What is an axial piston pump durability test bench?
The axial piston pump durability test bench is a device used to test and evaluate the durability and reliability of axial piston pumps in long-term operation. It simulates actual working conditions and continuously or periodically tests the performance of the pump to ensure that the pump meets specific performance standards and life requirements.
Q2: How to conduct a durability test of an axial piston pump?
The durability test of an axial piston pump usually includes several schemes, such as a full load test for 2400 hours, an overload test for 1000 hours plus an impact test for 100,000 times, or an overload test for 250 hours plus an impact test for 100,000 times. During the test, the volumetric efficiency, total efficiency, and parts wear of the pump need to be tested in accordance with industry standards and technical requirements.
Q3: What are the technical requirements for the durability test of an axial piston pump?
After the durability test, the volumetric efficiency of the axial piston pump should not be lower than the standard value by three percentage points, and the parts should not have abnormal wear and other forms of damage. Different types and displacements of inclined plate and inclined axis piston pumps have clear standard values for volumetric efficiency and total efficiency.
Q4: What are the test methods for axial piston pump durability test?
The test methods include pressure shock test for quantitative and manual variable pumps, pressure shock test for constant power variable pumps, constant pressure section shock cycle test for constant pressure variable pumps, etc. During the test, the inlet oil temperature of the tested pump should be controlled between 30ºC and 60ºC, and the test should be carried out according to the specified shock frequency and waveform.
Q5: What are the application areas of axial piston pump durability test bench?
The axial piston pump durability test bench is widely used in hydraulic transmission system research and production quality control in engineering fields such as engineering vehicles, aerospace, and shipbuilding heavy industry. It is an important tool to ensure the reliability and performance of the core components of the hydraulic system.
Q6: How to maintain and service the axial piston pump durability test bench?
Maintenance of the axial piston pump durability test bench requires regular inspection and cleaning of the test chamber, replacement of wear parts, calibration of sensors and measuring instruments, and operation and maintenance in accordance with the manufacturer's instruction manual.
Q7: What are the common problems with axial piston pump durability test benches?
Common problems may include inaccurate test data, unstable equipment operation, abnormal noise or vibration during the test, etc. These problems may be caused by aging equipment, improper operation, insufficient maintenance, or inaccurate understanding of test standards.
