1. Generally, new machines and equipment will not present this situation. After working for a long time, hydraulic oil pollution and other factors will promote the internal components of the hydraulic press to accelerate wear and tear, resulting in slower working power;
2, when 630 ton hydraulic pressWhen the oil temperature rises above 50 ℃, the movement lubrication of the hydraulic oil will decrease, which will cause the hydraulic press operating system to wear.
3. The volume of the fuel tank is small and the oil temperature rises quickly. If you choose a gear pump, the volume power is not high, which will cause the oil temperature to rise too fast.
4. Poor ventilation in the workshop, especially in the south of the dry season, the humidity is high and the oil temperature rises rapidly. If it is operated outdoors, try to choose a place without sunshine.
5. Do not always use the same type of oil with the same viscosity; regularly check the technical indicators of the internal leakage of the component, and replace it in time if any problem is found.
