Single arm hydraulic press is mainly applied to the technology of drawing, forming and pressing of metal products, processing non metal materials, pressing of powder metallurgy products, correction of shaft parts, pressing of sleeve parts and shaping and cutting edge of metal products. The use of a long time will inevitably appear such or such a fault, so in daily use, we should pay attention to the single arm hydraulic press inspection and maintenance.
Single arm hydraulic press can avoid air entering the hydraulic system in the hydraulic system. Once the air inadvertently enters the hydraulic system of the hydraulic press, it will cause the excessive noise or the oxidative deterioration of the contact between the hydraulic oil and the air, in addition to taking some air into the hydraulic system in daily work. In addition to the measures, check whether there is air in the hydraulic system, if any, it should be eliminated in time.
The hydraulic oil in the hydraulic system of a single arm hydraulic press must be kept crystal clear. Do not cause any impurities in the hydraulic oil. Because these impurities can easily plug gaps or throttle holes, the hydraulic system can not work normally, and can also speed up the parts in the wear hydraulic system. Therefore, in addition to the installation of the devices that obstruct the external impurities into the hydraulic system, the hydraulic oil in the hydraulic system should be replaced or filtered regularly.
In the long term use of a single arm hydraulic press to avoid leakage of the hydraulic press, but here it is worth saying that, if the internal leakage, although the leakage of this situation is unavoidable, but there is a certain amount of internal leakage, if the leakage of excess, then the pressure in the hydraulic system will lead to pressure. Not enough, causing internal movement instability. Leakage should be avoided. Proper sealing devices should be installed on the single arm hydraulic press, and the device should be inspected regularly.
