The galvanized silencer plenum is produced and processed with full color and fragrance. The smoke exhaust fire damper is a valve used to isolate the smoke and flames from the fire area, and can mechanically meet the requirements of fire safety and fire safety at a certain time. In order to reduce the damage caused by fire accidents to a minimum level, it is necessary to take measures to prevent fire safety and smoke exhaust system measures to control the spread of fire, and the effective installation of smoke exhaust fire dampers in ventilation, air conditioning and fire hydrant systems Ding, it has an important effect. Smoke exhaust and fire dampers are important components in ventilation, air conditioning and fire hydrant systems. What are the important functions they play in the system? The following website briefly introduces the main functions of smoke exhaust and fire dampers. I hope it will be helpful to you.
The inner cavity of the hot-dip galvanized air duct is smooth and clean, with low friction resistance, small ventilation loss, reduced energy consumption, saving operating costs, good sealing and sealing, and high pressure and tensile strength. At the same time, the excellent fire safety performance is one of the reasons why hot-dip galvanized ventilation ducts are widely used in engineering projects. Hot-dip galvanized air ducts are easy to install and easy to fabricate on-site. They are inseparable from civil construction and can be suitable for more complex cleaning, ventilation and air-conditioning projects.
Axial fans are generally used when flow requirements are high and pressure requirements are low. The cross section is generally the cross section of an aircraft wing. Small leaf spacing angle results in lower flow rate, and higher flow rate can be obtained by increasing the spacing. The viewing angle of leaves or leaf spacing can be non-adjustable or adjustable. The cutter head can be fixed or rotated around its longitudinal axis. Changing the leaf angle or spacing is one of the key advantages of axial fans. This is a cyclone with the same radial direction as the blades (that is, the wind frequency is parallel to the radial direction, such as an electric fan, and the external centrifugal fan of the air conditioner is an axial-flow centrifugal fan.
At present, the heat exchangers used for fresh air ventilation have two modes: stationary and rotating. Among them, the runner heat exchanger also belongs to the rotary type. From the perspective of normal use and maintenance, the static type is better than the rotary type, but for medium-sized machines with a capacity of more than 2×10000m3/h, it is generally maintained by the runner test heat exchanger, so it can be said to be static Both stationary and turntable types have advantages and disadvantages. The heat exchanger system fresh air ventilator is mainly composed of a heat exchanger system, a power unit, a filter control system, a noise reduction system and a casing.
The smoke exhaust fire damper is a fire safety component installed on the smoke prevention and exhaust system pipeline of mechanical equipment. Its main raw materials are alloy steel galvanized sheets and stainless steel sheets. The function of the fire damper manufacturer is to determine the period of fire. When the temperature exceeds 70°C, it will close and can meet the smoke leakage and fire safety requirements within a certain period of time. It has smoke isolation aluminum silicate The benefits of fiber. In normal times, the maintenance and maintenance of smoke exhaust and fire dampers are very important. Fire damper manufacturers tell you that the maintenance of smoke exhaust fire dampers is also critical.
Organic chemical FRP anti-corrosion is also called non-combustible inorganic FRP. Chemical FRP anti-corrosion ventilation ducts use modified magnesite binder as the powdery sand material and fiberglass cloth as the reinforcing material. This project solves the problem that ordinary magnesium ventilation ducts in my country are susceptible to moisture by implementing modified material technology and composite technology, and through certain process strategies. Disadvantages include low anti-halogen deformation strength, poor wear resistance, and severe brittleness in the later stages. In addition, the defects of galvanized plate ventilation ducts, which have poor corrosion resistance and make loud noises; chemical fiberglass anticorrosive ventilation ducts that are easy to ignite and deform; and fiberglass ventilation ducts that have low strength and are easily deformed, have been solved.
The centrifugal fan should be stored in a dry environment to prevent the motor from getting wet. When the centrifugal ventilator is stored outdoors, waterproof and rainproof measures are required. During storage and transportation, bumps and bumps of the centrifugal fan should be avoided to prevent the centrifugal fan from being damaged.
