Performance parameters:
Air volume: Determine the required air volume, noting whether it is under standard conditions (one atmosphere, 20℃, 65% relative humidity) or reference conditions, which usually refer to the inlet conditions.
Pressure: It is necessary to indicate whether the operating pressure is stable. If the pressure varies, the relative relationship between pressure and air volume, as well as whether the pressure is the static pressure at the outlet or the pressure difference between the inlet and outlet, should be clarified. Additionally, the inlet pressure should be described.
Gas type and specific gravity: Inform the type, composition, chemical properties, and whether the gas is explosive or toxic. If not specified, the manufacturer generally treats it as if it were air.
Gas temperature: Roots blowers of standard specifications are designed for conveying gases at room temperature. If the inlet temperature is excessively high, it is necessary to inform the manufacturer for special design to prevent the rotor from seizing in the cylinder due to thermal expansion.
Motor parameters: It is necessary to determine the voltage of the motor power supply, energy efficiency rating, and whether frequency conversion is required.
Product quality: Check whether the structure of the fan is reasonable, and understand the quality of the bearings, gears, oil seals, and other accessories selected by the manufacturer. These wear parts determine the quality and service life of the fan. For example, high-quality bearings can reduce wear and extend the operation time of the fan.
Noise Level: Although LONGMECH Roots blowers are characterized by low noise, there are still variations among different models. If the usage location has stringent noise requirements, such as sewage treatment facilities near residential areas, it is necessary to pay attention to the noise level during fan operation. You can consult the manufacturer for relevant data or refer to the product technical specifications.
Price factor: The price should be within a reasonable range. One should not solely pursue low prices, as this may lead to purchasing products of poor quality, resulting in increased maintenance costs in the later stages. It is necessary to consider factors such as comprehensive performance and quality, compare quotations from different suppliers, and choose products with high cost-effectiveness.
Installation and maintenance: Consider whether the installation of the fan is convenient and whether special installation conditions or supporting equipment are required. The LONGMECH Roots blower has a relatively simple structure and is easy to maintain, but it is also necessary to understand its daily maintenance points, such as the lubricant replacement cycle and the cleaning frequency of the air filter screen, to ensure proper maintenance during later use and prolong the fan’s lifespan.
