4 factors hinder the test of hydraulic universal testing machine

Hydraulic universal testing machineAfter purchase, it must be debugged by professional after-sales personnel before it can be used in working tests. Sometimes load problems occur during the test, resulting in inaccurate tests. Here are 4 reasons:

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.
