Precision Guide Structure: Adopting a four-column guide structure with high precision can ensure the parallelism between the movable beam and the worktable, avoid partial load during the pressing process, prevent mold damage, and ensure that each salt brick has uniform density and consistent shape.
Stable Hydraulic System: The hydraulic system is the power source of the press. A high-quality hydraulic system can output stable pressure, without pressure fluctuation during the pressing process, so as to avoid problems such as uneven density, cracking or deformation of salt bricks caused by unstable pressure.
Reliable Electrical Control System: The electrical control system controls the stroke, cycle time and action sequence of the press. A reliable electrical control system can ensure consistent operation parameters even during long hours of continuous work, avoiding production errors caused by program failures or signal instability.
Heavy-Duty Frame Design: The frame of the hydraulic press needs to bear huge pressure during operation. A heavy-duty frame with reasonable structure can effectively prevent machine shaking or deformation, especially when using multi-cavity salt brick molds, which can ensure the stability of the equipment and extend the service life of the machine.
Emergency Stop Button: Multiple emergency stop buttons should be installed at easy-to-reach positions of the equipment (such as the operation panel and both sides of the machine). When an emergency occurs, workers can press the button to immediately cut off the power and hydraulic pressure of the machine, stopping all operations to avoid accidents.
Safety Guard and Safety Door Interlock: A safety guard should be installed around the working area of the press, and a safety door interlock device should be configured. When the safety door is not closed, the press cannot start the pressing operation, which can effectively prevent hands or other parts of the body from entering the working area and avoid crush injuries.
Pressure Overload Protection: The hydraulic system should be equipped with an overload protection device. When the pressure in the system exceeds the set safety value, the device will automatically cut off the power or release the pressure to avoid damage to the hydraulic cylinder, mold and other components caused by overpressure.
Movable Beam Anti-Falling Device: During equipment maintenance or mold replacement, the movable beam may slide accidentally due to gravity. The anti-falling device can fix the movable beam in a safe position to prevent accidental falling and ensure the safety of maintenance personnel.
Fault Alarm Indicator: The equipment should be equipped with visible alarm indicators and sound prompts. When faults such as low oil level, hydraulic oil overheating, or abnormal electrical operation occur, the alarm will be triggered in time, reminding workers to check and handle the faults, so as to avoid further damage to the equipment.
Overload Protection: When the load of the motor exceeds the rated load, the overload protection device will automatically cut off the power supply of the motor to prevent the motor from burning out due to excessive load, which is especially important in the process of pressing large-size or high-density salt bricks.
Overheat Protection: The motor will generate heat during operation. If the heat cannot be dissipated in time, the temperature of the motor will rise, which will damage the insulation layer of the motor and affect its service life. The overheat protection device can monitor the temperature of the motor in real time. When the temperature exceeds the safe value, it will automatically stop the motor or trigger an alarm, so as to avoid motor damage caused by overheating.
Phase Loss and Phase Sequence Protection: For overseas customers, the power grid voltage and wiring may be unstable. The phase loss and phase sequence protection device can effectively avoid motor damage caused by phase loss, phase sequence error or unstable voltage, ensuring that the equipment can work normally under different power grid conditions.
Low Voltage and Over Voltage Protection: The motor has a fixed rated voltage range. When the power grid voltage is too low or too high, it will affect the normal operation of the motor and even burn out the motor. The low voltage and over voltage protection device can cut off the power supply in time when the voltage is abnormal, protecting the motor.
Effective Cooling System: A good cooling system (such as air cooling or water cooling) can quickly dissipate the heat generated by the motor during operation, ensure that the motor works at a stable temperature, and avoid performance degradation or damage caused by overheating, especially suitable for high-temperature production environments.
