In the operation, it is necessary to pay attention to the following problems in the planning or use process to ensure that the hydraulic system of the horizontal oil press can work reliably for a long time:
The oil press prevents air from mixing into the system and drains the air from mixing into the system in time. Air into the horizontal hydraulic system of the oil press, will cause noise and oil oxidation and transformation and other adverse consequences, it is necessary to adopt measures to prevent air mixing, and often will be mixed with the air out of the system.
Always keep the oil clean. There are impurities mixed in the oil of the frame type oil press, which will cause the slide valve to get stuck, block to save holes or gaps and make the hydraulic components can not work normally, and make the relative movement parts wear and tear. In addition to adopting oil filter and various equipment to prevent foreign impurities from mixing with the system, regular cleaning of oil filter and replacement of old oil. Hydraulic system in the oil press installation, to clean each hydraulic components and pipelines. After the test run, it is better to remove the components and pipes and install them after careful cleaning.
Frame type hydraulic press to prevent leakage. Leakage is not allowed outside, leakage is not prevented inside, but its leakage cannot exceed the allowed value, if leakage is too much, can make pressure does not go up, hydraulic press cannot reach the expected force (or torque). And the size of oil leakage is related to pressure bump, which will make the movement of operating parts unstable. In addition, because leakage amount is too much, make volume loses increase, oil temperature rises tall, in order not to appear leakage too much defect, should make there is appropriate space between relative motion parts and install appropriate sealing equipment.
Servo hydraulic press to prevent excessive oil temperature. General hydraulic system of a hydraulic press oil temperature to adhere to 15 ~ 50℃ is suitable. High oil temperature will bring a series of adverse consequences. The increase of oil temperature will dilute the oil, increase the leakage, and decrease the system power. The oil works at higher temperatures for simple transformation. To prevent the servo hydraulic machine oil temperature is too high, in addition to the plan to adopt the method of preventing oil heating (such as oil pump unloading and about the high power system to choose the volume speed regulation method, etc.), but also consider whether the tank has met the heat dissipation capacity. If necessary, additional cooling equipment may be provided.
