How to maintain the oil press?

September 07, 2021

All machinery and vehicles require maintenance, and oil presses are no exception. The maintenance of the oil press is actually very simple. You need to pay attention to the following points:

1. Pay attention to maintaining cleanliness; before and during the press, you must pay attention to the cleanliness of the piston surface, and clean the dirt and oil on the piston surface in time. Always pay attention to whether the hydraulic oil in the oil tank is clean, and filter it carefully when filling the oil tank. After using for a period of time, if the oil is found to be dirty, it should be filtered out in time, or replaced with new oil.


2. Pay attention to timely maintenance; during operation, you should always pay attention to the operating conditions of the machine, and pay attention to frequent inspections of vulnerable parts (such as cups, sealing devices, steel balls, pistons, etc.), and repair and exchange in time. The nuts should be tightened, and the machine should be overhauled and cleaned regularly. When the hydraulic oil press is out of use, the machine should be wiped clean, grease should be applied to the rust-prone parts and wrapped with greased paper or kraft paper to prevent rust.

3. Pay attention to maintaining reasonable pressure. When using the oil pump to pressurize, it should not be too fast or too violent to prevent the hydraulic parts from being damaged by the impact of the oil. When reducing the pressure, the oil return valve must be opened first. When the oil in the cylinder returns to the tank, the valve should be opened slowly to avoid a sudden drop in pressure. When in use, it is strictly forbidden to adjust the safety valve above the pressure gauge reading of 40 MPa (400 kgf/cm²) to avoid explosion of the pipeline or cylinder. It is strictly forbidden to lengthen the swing handle of the oil pump at will to prevent overload operation of various parts. Do not frequently trip the safety valve to avoid the valve sleeve wear and the spring will lose its elasticity due to excessive fatigue and cause the safety valve to fail.
