When choosing a Roots blower, the following aspects can be considered:
1、 Clarify application scenarios and requirements
1. Airflow and pressure: Determine the required range of airflow and pressure based on specific application scenarios. For example, sewage treatment plants may require Roots blowers with high air volume and low pressure, while chemical plants may require blowers with high pressure and high temperature tolerance.
2. Medium and temperature: Consider the medium, temperature, and properties processed by the system, and select the appropriate Roots blower material and sealing form. Different media have different material and sealing requirements, which need to be selected according to specific situations.
3. Noise requirements: If there are strict requirements for noise, Roots blowers with lower noise levels should be selected.
2、 Choose reliable brands and suppliers
1. Brand reputation: Choosing a well-known brand usually has better quality control and after-sales service, which can ensure the stable operation and long life of the equipment.
2. Supplier Strength: Understand the production, technical strength, and market reputation of suppliers, and choose manufacturers with a complete after-sales service system.
3、 Detailed review of technical parameters
1. Core technical parameters: including air volume, pressure, power, speed, efficiency, and noise. Ensure that the technical parameters of the selected Roots blower meet actual needs.
2. Energy efficiency ratio: Pay attention to the energy efficiency ratio of the fan, which is the amount of air generated per unit power, to ensure that energy is saved as much as possible while meeting demand.
4、 Consider price factors
1. Cost effectiveness: Compare prices from multiple manufacturers and conduct a comprehensive evaluation based on their performance parameters, brand reputation, and after-sales service. Choose products with high cost-effectiveness, rather than simply pursuing low prices.
2. Price range: Generally speaking, the price of small Roots blowers ranges from 1000 to 2000 yuan, the price of medium-sized Roots blowers is around 5000 to 10000 yuan, and the price of large Roots blowers may reach tens of thousands of yuan.
5、 On site investigation and trial use
1. On site inspection: Before making the final procurement decision, it is possible to conduct on-site inspections of the operational performance of Roots blowers in practical applications. You can visit the site of existing users to understand the operation and performance of the equipment under actual working conditions.
2. Trial: Before making a formal purchase, you can conduct some routine trials to understand the quality and performance of the device.
6、 Sign the contract and conduct acceptance inspection
1. Signing a contract: After determining the specific model and supplier of the Roots blower, signing a purchase and sales contract is a step to ensure the rights and interests of both parties. The contract should specify various technical parameters, prices, delivery time, payment methods, after-sales service, and breach of contract responsibilities.
2. Acceptance: After the equipment arrives, it shall be accepted according to the acceptance standards and inspection methods in the contract to ensure that the purchased equipment meets the technical requirements.
7、 Recommended brand
1. Brands such as Changsheng,,,, etc., have demonstrated their high technical level and competitive pricing compared to foreign brands in the market for Roots blowers.
2. Foreign brands such as Krauss, HIBON from Japan, Gardner Denver from the United States, etc. enjoy a high reputation in the global market, but their prices may be relatively high.
