What are the differences between IP68 and anti salt spray for cooling fans

What are the differences between IP68 and anti salt spray for cooling fans

What are the differences between IP68 and anti salt spray for cooling fans The IP68 rating and salt spray resistance of a cooling fan are two different concepts, with the main differences being as follows: Definition and Testing Standards IP68: The IP (Ingress Protection) protection level consists of two digits, the first digit representing the dustproof level and the second digit representing the waterproof level. IP68 is the highest level of dust and water resistance, where "6" indicates complete prevention of foreign intrusion, and "8" indicates that it can be immersed in water for a long time under a certain pressure, usually suitable for environments that are submerged in water for a long time. During testing, the fan will be placed in specific testing equipment to simulate different water pressures and soaking times to test its sealing performance. Salt spray resistance: Salt spray resistance refers to the ability of a fan to resist salt spray corrosion. Salt spray test is to place a fan in an atomization environment containing sodium chloride solution, atomize salt water into small particles through specific equipment, spray the fan at a certain concentration and time, simulate the use of the fan in coastal or other high salinity environments, and test its corrosion resistance. Protective purpose IP68： The main purpose is to prevent dust from entering the interior of the fan, avoid dust from causing wear and short circuits to the motor, blades, and other components of the fan, and ensure that the fan can work normally in humid or underwater environments, protecting the internal electronic components from water erosion. Salt spray prevention: It is to prevent the metal parts of the fan from corroding in a salt spray environment. The chloride ions in salt spray have strong corrosiveness, gradually damaging the protective film on the metal surface, causing rusting and corrosion of the metal, thereby affecting the structural strength and electrical performance of the fan, and reducing the service life of the fan. application environment IP68： Suitable for some harsh outdoor environments or special industrial environments, such as underwater equipment, high humidity mines, outdoor high-voltage electrical equipment, etc., where there is a large amount of water or dust, requiring high dust and waterproof performance of the equipment. Salt spray prevention: mainly suitable for coastal areas, salt chemical plants, offshore platforms and other environments with high salt spray concentration. In these places, salt spray corrosion of equipment is a serious problem, and equipment needs to have good salt spray prevention performance to ensure its reliability and stability. Implementation method IP68： Usually achieved through the use of sealing structures, such as sealing rubber rings, gaskets, and other materials, to seal the housing, motor, junction box, and other parts of the fan to prevent dust and water from entering. At the same time, special design and treatment will be carried out on the fan shaft, cable interface and other parts that are prone to water ingress to ensure a high level of dust and water resistance. Salt spray prevention: It is generally achieved by anti-corrosion treatment of the metal parts of the fan, such as electroplating, spraying anti-corrosion paint, and using corrosion-resistant materials such as stainless steel. These treatment methods can form a protective film on the metal surface, preventing chloride ions in salt spray from coming into contact with the metal, thus achieving the purpose of corrosion prevention. In addition, in the design of the fan, drainage and ventilation will also be considered to prevent salt spray from accumulating on the surface of the fan.

How to choose a fan suitable for a robotic vacuum cleaner?

How to choose a fan suitable for a robotic vacuum cleaner? 一、When choosing a fan suitable for a robotic vacuum cleaner, the following aspects need to be considered: 1、Cooling requirements: During the operation of the robotic vacuum cleaner, components such as motors and batteries generate heat, which needs to be dissipated through a fan. According to the power and heat dissipation requirements of the robotic vacuum cleaner, select a fan that can provide sufficient air volume and static pressure to ensure that the equipment operates within the normal temperature range and extends its service life. Generally speaking, high-power robotic vacuum cleaners require fans with higher air volume and static pressure. 2、Size and installation method: The size of the fan should match the internal space of the robotic vacuum cleaner, ensuring that it can be installed in the appropriate position and will not affect the normal operation of other components. In addition, it is necessary to consider the installation method of the fan, such as screw fixation, buckle connection, etc., and choose a fan that is easy to install and disassemble for later maintenance and replacement. 3、Noise level: Robotic vacuum cleaners are typically used in home environments, and noise level is an important consideration factor. Choosing a low-noise fan can reduce the noise interference generated by the robotic vacuum cleaner during operation, making it more comfortable for users to use. Generally speaking, the noise level of a fan should be below 40 decibels to ensure a quieter working environment. 4、Reliability and lifespan: Robotic vacuum cleaners require long-term stable operation, so the reliability and lifespan of fans are crucial. Choose fans with reliable quality and good brand reputation. Usually, these fans are made of high-quality materials and advanced manufacturing processes, which can maintain stable performance during long-term use, reduce the frequency of failures and repairs. At the same time, attention should be paid to the expected lifespan of the fan, which is generally required to be over 20000 hours. 5、Voltage and power: Select the fan voltage and power that match the power system of the robotic vacuum cleaner. Generally, sweeping robots use DC power supply, with common voltages such as 12V and 24V. The rated voltage of the fan should be consistent with the power supply voltage of the sweeping robot to ensure that the fan can work normally and will not damage the equipment due to voltage mismatch. 6、Air volume adjustment function: Some high-end floor cleaning robots may need to adjust the air volume of the fan according to different working modes or environmental temperatures. If there is such a need, fans with air volume adjustment function can be selected, such as fans controlled by PWM (pulse width modulation) signals, which can flexibly adjust the air volume according to the needs of the equipment. 二、Sanyo SanAce fan suitable for robotic vacuum cleaners San Ace 120GP 9GP1224P1G001 High reliability: Compliant with UL, CSA, EN standards, and RoHS directives, it can maintain stable performance during long-term operation of robotic vacuum cleaners.

How to choose the appropriate axial flow fan according to the application scenario

How to choose the appropriate axial flow fan according to the application scenario

How to choose the appropriate axial flow fan according to the application scenario Axial fans are widely used in various electronic devices, and different models of axial fans have differences in performance. Differences in air volume testing for different models of axial fans and how to choose the appropriate fan. 一、Differences in Airflow Testing of Axial Fans of Different Models 1.Size difference: The size, number, and shape of blades of an axial fan can all affect its airflow. Generally speaking, larger axial fans have a higher air volume, but the specific amount needs to be determined based on actual test results. Fan size: Generally, the larger the impeller diameter, the larger the area swept by the fan, and at the same speed, the greater the air volume. For example, large axial fans are suitable for exhaust in places such as dust and gravel fields, as they can generate a large amount of air flow; Small axial fans are used for ventilation and heat dissipation of mechanical equipment, with relatively small air volume. 2.Motor performance: The power and speed of the motor can also affect the airflow of the axial fan. High power, high-speed motors typically generate greater airflow. Motor type and power: Different types of motors have different characteristics. For example, direct current motors (DC) have the characteristics of small size, light weight, and high efficiency, while permanent magnet motors (EC) have high efficiency, energy conservation, and environmental protection. The higher the power, the more it can usually drive the fan to operate at a higher speed, thereby generating a larger air volume. 3.Design optimization: Some special axial flow fan designs, such as air guide design, shock absorption design, etc., can improve the stability and uniformity of their air volume, and enhance their performance. 二、How to choose the appropriate axial flow fan according to the application scenario 1. Consider the usage environment: Choose a suitable axial fan according to the different application scenarios. For example, in industrial equipment that requires a large amount of heat dissipation, axial fans with high air volume and good heat dissipation effect should be selected; In situations where a quiet environment is required, a low-noise axial fan should be chosen. Environmental factors: If the usage environment is harsh, such as high dust and humidity, a fan with a higher protection level should be selected to prevent dust from entering the motor or causing faults such as short circuits. In environments with flammable and explosive gases, explosion-proof axial fans should be selected. Noise restriction: In some places with high noise requirements, such as offices, hospitals, etc., low-noise fans should be selected for operation. Generally speaking, fans with lower speeds and more blades produce relatively less noise. 2.Consider installation space: The size of the installation space will affect the selection of axial flow fans. In situations where space is limited, axial fans with moderate size and air volume should be selected to ensure their normal operation and save space. At the same time, the installation method of the fan should be considered, such as wall installation, pipeline installation, etc., to ensure that the installation is firm and does not affect the activities of surrounding equipment and personnel. 3.Consider maintenance and cost: Different models of axial fans also have differences in maintenance and cost. When choosing, factors such as service life, maintenance convenience, and purchase cost should be considered, and the pros and cons should be weighed comprehensively. Cost factor: The prices of fans from different brands and models vary, and fans with higher power have relatively higher operating costs. Therefore, it is necessary to consider both budget and usage needs to choose products with high cost-effectiveness. 4.Reference air volume test data: You can refer to the air volume test data of professional institutions to understand the performance of different models of axial fans, so as to more accurately select the appropriate axial fan. Air volume requirement: Determine the required air volume based on the actual usage scenario. If used for ventilation in large factories, high air volume fans are required; For cooling small devices, choose a fan with lower air volume. The specific air volume value can be determined by calculating the spatial volume, air exchange rate, and other methods. 三、case study Taking air conditioning in household appliances as an example, it requires a large amount of heat dissipation during operation. When choosing an axial flow fan in an air conditioner, factors such as air volume, noise level, and usage environment should be considered.

Characteristics of SanAce centrifugal fan

Characteristics of SanAce centrifugal fan

Characteristics of SanAce centrifugal fan 1、Definition of centrifugal fan Centrifugal fan (centrifugal fan) is a special type of fan structure, with its core component being a motor located at the center. The motor is equipped with an impeller (feather root car), and unlike axial fans, it does not have a frame similar to axial fans. Centrifugal fans generate centrifugal force through the rotation of the impeller, which turns the inhaled air 90 degrees and discharges it radially from the side. This unique wind discharge method makes it significantly different from axial fans in terms of aerodynamics. 2、Structural characteristics of Shanyang SanAce centrifugal fan Central motor design: The SanAce centrifugal fan places the motor at the center of the fan, which makes the entire fan structure more compact and also facilitates better control of the fan's operating state, ensuring stable rotation of the impeller. Frameless structure: Unlike axial fans, SanAce centrifugal fans do not have frames. This design reduces resistance during air flow, improves air flow efficiency, and enables the fan to more effectively draw in and exhaust air. Equipment of inlet nozzle: In order to suction air more efficiently, SanAce centrifugal fans are usually equipped with an inlet nozzle. By clearly separating the suction and discharge spaces, the inlet nozzle can help the fan more effectively suck in air, thereby maximizing the capacity of the centrifugal fan and improving overall ventilation efficiency. 3、Performance characteristics of Shanyang SanAce centrifugal fan The main features include efficient heat dissipation, high static pressure and high air volume, energy saving and low consumption, waterproof and dustproof, low noise, and long service life. P-Q characteristic curve: The P-Q characteristic curve (air volume static pressure characteristic curve) of SanAce centrifugal fan is close to a straight line, which is significantly different from the characteristic curve of axial flow fan. The P-Q characteristic curve of axial fans usually has a flat rotational stall region, while centrifugal fans do not have this region. This means that centrifugal fans have a wider range of applications in terms of ventilation resistance and working point position compared to axial fans, and can better adapt to different ventilation needs. Energy consumption and noise performance: The energy consumption curve and sound pressure level curve of SanAce centrifugal fans may vary depending on different models. At the same operating point, using a centrifugal fan may result in lower sound pressure and lower energy consumption than using an axial fan. This makes centrifugal fans have significant advantages in situations where strict requirements are placed on noise and energy consumption. High static pressure and strong wind suction capacity: SanAce centrifugal fans have the characteristics of high static pressure and strong wind suction, which makes them very suitable for overall air replacement inside large equipment and heat exchangers that require a large amount of moving air. In these application scenarios, centrifugal fans can effectively promote air flow, achieve efficient air circulation and heat exchange, thereby meeting the heat dissipation and ventilation needs of large equipment. Certified by multiple international standards such as UL, CSA, and EN, and complying with the ROHS directive, the product is environmentally friendly and pollution-free, ensuring its safety, reliability, and environmental friendliness 4、Application scenarios of SanAce centrifugal fan Internal air replacement of large equipment: In large industrial equipment or data centers, the air inside the equipment needs to be regularly replaced to maintain a good working environment. The SanAce centrifugal fan, with its high static pressure and strong wind suction capacity, can effectively discharge the hot air inside the equipment and introduce fresh cold air, achieving rapid replacement of air inside the equipment and ensuring stable operation of the equipment. Air propulsion of heat exchangers: Heat exchangers are important equipment used in many industrial systems to achieve heat transfer. In a heat exchanger, a large amount of air flow is required to remove heat and achieve efficient heat exchange. SanAce centrifugal fans can provide powerful aerodynamics, pushing air to flow quickly in the heat exchanger, improving heat exchange efficiency, and ensuring stable operation of the system. Other occasions that require a large amount of air movement: In addition to the above application scenarios, SanAce centrifugal fans can also be applied to other occasions that require a large amount of air movement, such as ventilation systems, air conditioning systems, etc. In these systems, centrifugal fans can effectively promote air flow, achieve air circulation and exchange, and create a comfortable living and working environment for people.
