Daily operation and precautions for fire damper equipment
Fire dampers installed in central air conditioning duct systems are temperature-controlled using fusible alloys. They utilize gravity and spring mechanisms to close the damper. In the event of a fire, flames entering the ductwork melt the easily fusible alloy in the damper at high temperatures, or cause shape memory alloy deformation, automatically closing the damper and preventing fire spread through fire-rated areas. Below, we will explore the structure and selection points of fire dampers.

Fire damper equipment scope of application and cleaning
Fire dampers are volume control valves installed in air conditioning and ventilation ducts. The blade closing angle is controlled by a motor. They are widely used in civil residential buildings, industrial ventilation and air conditioning, and air purification projects, and are also suitable for occasions where manual operation is inconvenient. Below, we will learn about the scope of application and cleaning of fire dampers.

Classification and Selection of Fire Damper Equipment
Fire dampers are generally installed where pipelines pass through firewalls to prevent fire spread. They provide output signals, and the valve closes when the temperature exceeds 70 or 280 degrees, causing the fan to shut down. Let's explore the classification and selection of fire dampers.

What are some common problems with CNC plate rolling machines?
Numerical control plate rolling machines always have some problems during use. How to solve them when they occur? Here are some common problems: After the numerical control plate rolling machine is started, the stepper motor vibrates but does not rotate. This phenomenon is usually caused by a phase failure of the stepper motor or its control system. Therefore, the drive power supply should be checked. It may also be caused by mechanical defects.
