In this hot summer, the heat makes people feel tired. Even if they don't work, the sweat will flow down. What is the impact of this high temperature on our hydraulic press? High temperature will also make the hydraulic oil temperature rise. If the oil temperature is too high, the following faults and adverse effects will occur:
In this hot summer, the heat makes people feel tired. Even if they don't work, the sweat will flow down. What is the impact of this high temperature on our hydraulic press? High temperature will also make the hydraulic oil temperature rise. If the oil temperature is too high, the following faults and adverse effects will occur:
① High temperature of the hydraulic oil will reduce the cleanliness of the oil, increase the leakage, and significantly reduce the volumetric efficiency of the pump and the efficiency of the whole system. As the cleanliness of the oil is reduced, the oil film of the moving parts such as the slide valve becomes thinner and cut, and the friction resistance increases, which leads to the aggravation of wear and the heating of the hydraulic press, which brings higher temperature.
② The hydraulic oil temperature is too high, which makes the mechanical thermal deformation, makes the gap between the moving parts with different thermal expansion coefficient smaller and stuck, causing action failure, and affecting the accuracy of hydraulic equipment, resulting in poor processing quality of parts.
③ If the temperature of hydraulic oil is too high, the rubber seal will be deformed, and the rubber seal will be aged earlier, the service life will be reduced, the sealing performance will be lost, and the leakage will cause further heating and temperature rise.
④ If the hydraulic oil temperature is too high, it will accelerate the oil oxidation deterioration, precipitate asphalt material, and reduce the service life of hydraulic oil. The precipitates block the damping hole and gap valve port, resulting in pressure regulation failure, flow instability of flow valve and direction valve stuck not reversing, metal pipeline elongation and bending, and even rupture.
Therefore, when the pressure of your hydraulic press is not up, the accuracy is not accurate, and the sealing ring is damaged, the oil temperature of the hydraulic press may be too high. You can consider installing an air conditioner cooler for your hydraulic press.
