What are the ways to operate the marine dampers
The mode of operation of the damper can vary: it can be purely manual, pneumatic or electric; They are usually used to regulate air flow and ensure the normal operation of a ship's internal systems. The design and manufacture of marine dampers take into account the special environment and requirements of ships, such as marine environment, ship vibration, high temperature, high humidity and other factors, to ensure a high degree of high reliability and durability.
Overview
In general, manually operated dampers are usually used in small ventilation duct systems.
1. Manually rotating the regulating lever: The damper usually has a regulating lever on top of the damper that can be rotated manually to control the speed of the fan and the amount of ventilation. Rotating it to the left reduces the amount of ventilation and rotating it to the right increases the amount of ventilation.
2. Manually Controlled Valves: The damper can also be manually controlled to regulate the amount of ventilation by controlling the degree of valve opening. Generally speaking, when the valve is completely closed, the air flow in the ventilation duct will be completely blocked; when the valve is fully open, the ventilation will be maximized.
In addition to manual operation, the damper can also be operated by electric means.
1. Control panel: Electric damper can be operated through the control panel, the control panel is usually equipped with on, off, pause and other buttons, easy to operate. It should be noted that, before use, make sure that the power supply of the control panel has been connected.
2. Remote control: for long-distance operation, you can use a remote control to operate the electric damper. The remote control can usually control the speed of the fan, the amount of ventilation and the switch and other functions. It is important to note that you must make sure that the signal transmission between the remote control and the motorized fan is good before use.
Pneumatic switch is a method of using compressed air or gas-driven switching, which can be realized by remote control to switch on and off the air duct damper. It has the advantages of fast response speed, high reliability, etc., but it needs to be equipped with a special gas source system, the price is high, and it is easy to be affected in harsh environments.
