Product details
The centrifugal fan is a machine that relies on input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draft induction in boilers and industrial furnaces; cooling and cooling in air conditioning equipment and household appliances. Ventilation; grain drying and selection; wind tunnel wind source and hovercraft inflation and propulsion, etc.
Mechanical characteristics
The centrifugal fan is essentially a variable flow and constant pressure device. When the rotational speed is constant, the theoretical pressure-flow curve of the centrifugal fan should be a straight line. Due to internal losses, the actual characteristic curve is curved. The pressure generated in a centrifugal fan is greatly affected by changes in inlet air temperature or density. For a given intake air volume, the pressure generated is the lowest at the highest intake air temperature (lowest air density). For a given pressure and flow characteristic curve, there is a power and flow characteristic curve. When the blower runs at a constant speed When, for a given flow rate, the required power increases as the inlet air temperature decreases.

一、What is a bamboo chip machine? A bamboo chip machine is a machine specially used to cut bamboo into slices. It is one of the indispensable equipment in the bamboo processing industry. 二、 Bamboo chip machine varieties According to different working methods and uses, bamboo chip machines can be divided into the following varieties: 1. Manual bamboo chip machine A manual bamboo chip machine is a simple mechanical equipment, mainly composed of a cutter, a support frame and a manual control device. It is suitable for small-scale bamboo processing, with simple operation and low cost. 2. Electric bamboo chip machine An electric bamboo chip machine is a machine that uses an electric motor to drive the cutter to rotate. Compared with a manual bamboo chip machine, an electric bamboo chip machine has higher working efficiency and is more convenient to use. It is suitable for small and medium-sized workshops and enterprises. 3. Fully automatic bamboo chip machine A fully automatic bamboo chip machine is a fully automated bamboo chip production equipment that can realize automatic cutting, feeding, tool replacement and other functions, and is suitable for large-scale bamboo processing business. 三、 Use of bamboo chip machine When using bamboo chip machine, you should pay attention to the following points: 1. Wear protective equipment such as safety helmets and gloves during operation; 2. The cutting knife of bamboo chip machine should be kept sharp to avoid uneven cutting or rotten edges; 3. The wires, plugs and other electrical equipment of bamboo chip machine should be checked regularly to prevent electrical failures such as short circuits. The above is an introduction to bamboo chip machine varieties. By understanding the models, sizes, parameters, specifications, types and other contents of different varieties of bamboo chip machines, you can better choose the bamboo chip machine that suits you and improve the efficiency and quality of bamboo processing.
The fixed drying room is a new type of high-efficiency and energy-saving dryer that is not affected by the external environment, weather, season, and climate. It can work continuously for 24 hours and can well guarantee the quality, color, appearance, and effectiveness of the dried products. The ingredients can meet the drying requirements of different products, so it can be widely used in drying in aquatic products, meat products, Chinese medicinal materials, agricultural and sideline products, fruits and vegetables, food, grains, seeds, clothing, tea, paper, wood, industry and other fields.
