There are many reasons why a power press may slow down. Here are some common reasons:
1. Hydraulic system failure: Power presses usually rely on hydraulic systems to provide driving force. If the hydraulic system is underpressured, the oil is contaminated, or the oil level is too low, the machine may run slower.
2. Motor failure or power supply problem: If the power supply to the motor is unstable or the motor itself fails, the press may run slower.
3. Overloading the press: If the press is overloaded and exceeds the design range, it will run slowly or even shut down.
4. Poor lubrication: If the key components of the power press lack sufficient lubrication, it may cause increased friction and slow down the operation.
5. Air resistance or pipeline blockage: For pneumatic or hydraulic power systems, blockage of pipelines or air compression systems may also cause the equipment to run poorly and slow down.
6. Control system failure: If there is a problem with the control system of the press, the machine's operating parameters may not be adjusted normally, affecting the working speed.
7. Ambient temperature is too high or too low: Extreme ambient temperature may also cause the press to run slowly, especially the hydraulic oil or motor may not perform well in extreme temperatures.
8. Wear or failure of mechanical parts: If some mechanical parts inside the press are worn or damaged, it may also cause the machine to run unsmoothly and slow down.
Summary: To find out the root cause of the slow speed of the power press, it is recommended to check from multiple aspects such as the hydraulic system, electrical system, and mechanical parts.
