- ①In order to prevent the air from penetrating into the Hydraulic Press, it should be ensured that all parts of the single-arm hydraulic press should be sealed.
- ②Generally, before installing the components of the single-arm hydraulic machine, some kerosene should be used for cleaning, and then after some pressure resistance and tightness tests are carried out, it can be installed only after passing the test.
- ③When installing various valves of a hydraulic machine, you must first pay attention to the direction of their inlet and outlet ports and some parts. Do not install them backwards, otherwise it will cause some failures and accidents. For some two holes that can be opened with two same functions, do not rush to block them after installation.
- ④Some directional control valves of single-arm hydraulic presses should generally be kept in the horizontal position of the axis.
