Factors that cause the rating of hydraulic universal testing machine

Newly purchasedHydraulic universal testing machineThere is no guarantee that the experiment will be completed very smoothly during the test. Sometimes the rated load will occur during the test. The reasons for this phenomenon are as follows:

1. The system has serious oil leakage, so the screw joint should be checked

2. The viscosity of the oil is low, and the viscosity of the oil must be adjusted.

3. The belt that drives the hydraulic pump slips and looses due to oil and ages. Tighten the belt or replace the belt

4. There is dirt in the oil return valve, which makes the oil return valve core and valve port not sealed enough. There is oil leakage during loading. The oil return valve should be cleaned.
