Uses: The location and role of the blower in the process, distinguishing blower uses from vacuum uses.
Gas properties: Name. Molecular weight, toxicity, corrosiveness and explosiveness, composition ratio of the gas mixture, dust content, etc.
Operating parameters: inlet temperature, inlet pressure, boost (exhaust pressure or vacuum), flow rate, and permissible limits for exhaust temperature and noise.
Environmental conditions: place of installation (outdoors or indoors, on the ground or on a floor), local atmospheric pressure, temperature and humidity, etc.
Common conditions: water supply, power supply (including supply voltage), etc.
Others: 1) Variable operating conditions: pressure or flow rate adjustment requirements: 2) Operating conditions: continuous operation time, or intermittent operation frequency; 3) Requirements for painting (including color), packaging, and transportation.
Selection Calculation
According to the use requirements, selected blower material and sealing type, preliminary selection of product models and specifications.
Accounting for the performance parameters of the preliminary product under the specified operating conditions, including flow rate, shaft power and exhaust temperature.
After selecting the blower model and specifications, determine the prime mover (motor) and transmission method, and select supporting accessories.
Make a selection list
Blower: 1) Model: caliber, material and sealing form, etc.; 2) Performance parameters: flow rate, pressure rise (or vacuum height), rotational speed and shaft power, etc.
Motor: voltage, power, number of poles (or speed), protection class and insulation class, etc.
Transmission method: direct connection, belt connection (whether anti-static belt), or other transmission methods.
Matching accessories: mufflers, filters, elastic joints, safety valves, check valves, acoustic enclosures, model specifications for starter cabinets, etc.
