What are the factors that affect the pressure change of the automatic cutting machine?
1. System pressure is also a decisive factor
System pressure is the rated pressure output by the motor-driven oil pump. The higher the rated output pressure, the greater the machine pressure. However, this type of hydraulic pump has long been standardized, the output pressure of the medium-pressure hydraulic pump is generally around 200 kg. If the pressure is too high, the cost of its supporting hydraulic actuators, pipes, joints other components will increase exponentially, its technical difficulty will also double.
The above two items are important factors that determine the pressure of the cutting machine. When the machine pressure is enough the machine has no pressure, we know to check, which will be of great help in analyzing repairing the machine; it should be noted that in actual maintenance, we should also consider factors such as the degree of pipeline sealing, whether the actuator is leaking, whether the seal is damaged. Comprehensive analysis; only in this way can the root cause of the fault be quickly eliminated.
2. The size of the oil cylinder is one of the decisive factors.
When the oil pump output pressure remains unchanged, the larger the oil cylinder is, the greater the pressure generated by the machine. This is why the oil cylinder of a large pressure machine is larger than that of a small pressure machine.
Why is the downward speed of the cutting machine slow but the upward speed is normal?
1. Check if there is debris stuck in the travel switch the travel switch is broken;
2. Change the position of the relay press it hard;
3. The solenoid valve is faulty, such as a stuck valve;
4. The oil pump fails to pump oil, a professional needs to check it.
