Installation of electric dampers
Release time:
Dec 03,2020
Electric damper manufacturing typically employs a structure consisting of thin-plate stamping and integral welding. This structure comprises an external frame, damper blades, sealing strips, a front-and-rear bearing linkage system, and an electric actuator. The adjustable damper can be welded or bolted to the duct via flanges on the frame. Damper materials commonly used include Q235, Q345, 304, 316, and 316L.
Electric damper It is an automatic control device for fan dampers, designed to meet the growing demand for automation in coal mining machinery. This equipment features two operating modes: electric and local. It enables remote control of damper doors, includes overtravel protection, and offers both electric and manual switching capabilities, significantly enhancing the safety and reliability of the equipment. This device is easy to install, debug, operate, and maintain, making it an ideal replacement for insert-type dampers in fans.
Electric damper Terms of Use:
1. Power requirements: Single-phase AC power.
Voltage: 220V; Frequency: 50Hz
2. Environmental conditions
( 1 ) Temperature and relative humidity
Temperature: -10-50 ℃. Relative humidity: not exceeding 95 %.
( 2 Atmospheric pressure: 86–106 kPa 。
( 3 The surrounding air contains no corrosive media.
Technical parameters of the electric damper: output torque, actuation speed, angle adjustment range, and drive signal type, etc.
Electric damper Installation locations: Typically installed at coal mills; at the cold and hot primary air ducts at the inlets of forced-draft and induced-draft fans; and at circulating flue gas ducts (including the inlet and outlet flue gas ducts of desulfurization and denitrification flue gas ducts, as well as the inlet and outlet flue gas ducts of waste heat boilers). / Bypass flue gas ducts, etc.
( 1 Before installing the electric damper, please check that the resistance between the coil and the valve body, as well as the supply voltage and input signal, meet the requirements. It is recommended to perform a simulated operation test.
( 2 After installing the electric damper, the open and closed indicator positions of the air valve controller should correspond to the actual status of the air valve and be oriented toward a location that is easy to observe.
Electric damper Structural Design: Electric damper manufacturing typically employs a monolithic welded structure formed by thin-plate stamping. This structure consists of an external frame, damper blades, sealing strips, a front-and-rear bearing linkage system, and an electric actuator. The adjustable damper can be either welded or bolted to the duct via the frame’s flanges. The material of the damper is typically... Q235，Q345、304、316、316L Wait.
