What Is The Principle Of High-frequency Fatigue Testing Machine?

1. The high-frequency fatigue testing machine is mainly designed according to the principle of electromagnetic resonance in physics. Generally, its working load is relatively large, and the measurement time is relatively short when the frequency is between 80-250 hz.

2. The low-frequency fatigue testing machine works according to the electro-hydraulic servo principle, mainly according to the reciprocating motion of the moving cylinder, and the load and frequency are relatively low. Because in the process of operation, if the frequency is relatively high, the wear degree of the parts is relatively large, resulting in high cost of later maintenance, so it is not recommended to use high-frequency testing instruments.

Maintenance of fatigue testing machine:

1. Regularly replace the oil filter element and clean the deteriorated oil. To prevent hydraulic oil from damaging the machine. Therefore, replace the filter element in the oil circuit of the system regularly, drain the oil in the oil filter, more effectively prevent the occurrence of faults, and extend the operation time and service life of the servo valve.

2. Replace the hydraulic oil regularly and strengthen the management of hydraulic oil, because the worn metal debris of various instruments in the hydraulic system will reduce the operation efficiency of the machine. According to domestic data, only when the hydraulic oil is replaced every 10 months can the equipment be guaranteed from unexpected shutdown, and the operation efficiency of the machine be improved.
