Safety design requirements for thermostatic presses

Working principle of thermostatic press:

The work parts to be processed are placed in a specific mold and then placed in a closed container filled with liquid. Then the pressurization system continuously pressurizes it, and transmits it according to the liquid pressure, so that each surface of the object can withstand the same pressure, and is slowly formed under the constraints of the mold. In the compression process, the molecular spacing of the workpiece continues to shrink and the density increases, which changes the physical and chemical properties of the workpiece.

In order to ensure the safety and reliability of the thermostatic press in the pressure and temperature control level and emergency stop operation, full attention should be paid to its safety design, and the following three aspects are mainly required:

1. The design should meet the standards, and always focusing on safety is an important part.

2. To achieve clear protection and alarm levels, safety and reliability, separate the limit alarm, processing and general control alarm on the control loop, which not only improves the reliability of the action, but also avoids mutual influence; Technically, choose the dual safeguards of mechanical-hydraulic and electrical control.

3. Pay attention to the reliability of safety control. All safety-related controls are equipped with special electrical safety controls to ensure reliable safe maintenance actions. Blasting parts equipment must be manufactured by a unit that has obtained a production license issued by the supervision authority.
