What is the working principle of a household hood?

Household range hoods are essential electrical appliances in modern home kitchens. With a range hood, it is guaranteed that the entire home will not be enveloped in soot to ensure the physical and mental health of home users, but you know what the working principle of the range hood is. ? To understand the working principle of the range hood, Xiao Bian reminds you to understand the composition of the range hood.

The main components of the range hood:

The household range hood is mainly composed of a fan system, a control system, an oil filtering device, a casing and a suspension device. The fan system is the heart of the range hood, usually composed of a motor and an impeller, and the power of a range hood is also determined by the fan system. It is decided that the control system is the most scientific and technological component of the hood. There are micro-circuit boards to control the power and switch of the hood. The oil filter device mainly refers to the net and the oil filter cavity. The outer casing and the suspension device are generally resistant to stainless steel. Made of high temperature corrosion resistant materials.

The main working principle of the range hood:

The main working principle of the range hood is determined by its main composition. The range hood is designed and developed based on aerodynamics. The principle can be summarized as: negative pressure, suction, separation, discharge and other major steps:

1. The motor runs at the same time to drive the coaxially coupled impeller to rotate.

2. Rotating agitation of the impeller produces a fast ascending airflow to the fan blades of the hood.

3. The airflow forms a vortex negative pressure zone near the air inlet to make the soot gas rise rapidly.

4. Rotating friction occurs when the oil smoke runs to the oil net to separate the oil smoke.

5. After the oil adheres to the oil net and accumulates to a certain amount, it will flow into the oil cup along the oil guiding column due to gravity.

U Ground Screws , also named driven piles in Russia and sometimes it is called U Ground Anchors in Canada and in America. Why is named U Ground Screw we call? Because of the top of this type Ground Screw has one open [U box".The U shape in the top of Ground Screw Anchors have important effect to support wood bars, building supports and other connectors. Ground screw type U look like very stable and can hold on heavy gravity. The structure of U ground screw anchors includes two parts, one is U box on the top, which can hold more power, another is the pile of Screw Piles , the blade of piles is very solid by welded of our automatic machine, which can not damage when installing them. Ground Screw Anchor type U is often used by construction workers to fixing the wooden house, the wooden wall of dock in sea and some prefab houses.
