In the installation and commissioning stage of the hydraulic press, on the one hand, the hydraulic press system should be protected from secondary pollution, and on the other hand, it should be ensured that the pollution degree of the external pipeline meets the product requirements before it can be connected to the hydraulic system.
1. It is not allowed to use the hydraulic press system in the equipment to circulate and flush the external pipeline. The external pipeline must be flushed separately, and the pollution degree test is qualified before it can be connected to the hydraulic system. This is also one of the most important links between pollution degree and quality control.
2. During commissioning, when adding hydraulic oil to the hydraulic system, the oil filter must be used to refuel. At the same time, pay attention to the grade of the filter element of the oil filter and replace the filter element regularly. It is not allowed to directly add hydraulic oil to the hydraulic system.
3. The pipelines and cylinder interfaces of the hydraulic system must be well protected, and they must be installed and disassembled at any time to avoid pollution of the pipelines.
