Introduction to electric adjustable air door:

Electric adjustable dampers are used in smoke and air ducts to regulate the working flow rate. At different positions where the blades rotate 90 degrees, they have the advantages of rotating and recording, and excellent regulation performance through different working flow rates. The action mode should adopt adjacent blade relative or parallel (only used for centrifugal net machine inlet). For the regulating door of the hot air positive pressure system, there is also a sealed air joint at the shaft end bearing, which can be connected to seal air to block the leakage of hot air.

The regulating damper adopts a thin plate stamping and integral welding structure, and its regulating characteristics are that the resistance coefficient is linearly related to the blade opening within the range of 25 ° to 75 °; Streamlined blades can improve the distribution of airflow wake.

The maximum working pressure of the electric control door shall not exceed 2000mmH20, the maximum working temperature shall not be less than 420 ° C, and the working medium shall be smoke or air

Electric adjustable circular air door | Electric adjustable baffle air door is used as a shut-off medium in the flue gas duct system of power plant boilers. The electrically adjustable circular air door has two functions: fully open and fully closed, allowing the medium to flow or close completely in the pipeline, and generally does not have an adjusting effect. Electric adjustable circular air door | Electric adjustable circular air door has the advantages of flexible opening and closing rotation, small driving torque, no jamming in hot state, tight sealing, and can withstand high pressure and temperature in the system.

The air door adopts a steel plate folding and welding structure, and the blade shape is a flow line diamond structure, with small flow resistance and sufficient strength. The blades are surrounded by 0.5-1mm thick elastic stainless steel sheets, and the sealing performance increases with the increase of system pressure; The bearings at both ends are spherical self-lubricating self-aligning bearings, so it will not affect the rotation of the blades when they bend. Jiangsu Shouchuang Pipeline Equipment Co., Ltd. specializes in producing electric adjustable circular dampers, electric adjustable baffle dampers, electric baffle dampers, electric plug-in circular dampers, and adjustable circular baffle doors.

The driving methods of electrically adjustable circular dampers include electric, manual, pneumatic, etc; It can be controlled locally, remotely, or centrally by computer.

Users should pay attention to the following when choosing an electrically adjustable circular air door:

The meaning of the electric adjustable circular air door specification D × W × L is: D is the thickness of the air door; W is the dimension perpendicular to the blade axis (i.e. the exit axis direction); The electrically adjustable baffle damper H has a blade length dimension. Electric adjustable circular air door, and special attention should be paid to L as the horizontal dimension to ensure that during installation, the blade sleeve is in the horizontal plane, ensuring the service life of the air door. The width (W) or length (L) in the specifications of the electrically adjustable circular air door for Jiangsu's first pipeline equipment refers to the inner edge size of the air door section, which is generally consistent with the inner edge size of the pipeline. To facilitate user selection, when ordering the closed baffle, users must provide the following technical parameters: the position and function of the electrically adjustable circular air door in the pipeline; Circulating medium; Maximum work pressure; Maximum operating temperature.
