    Application Scenarios of NSRH Blowers in the Chemical Industry
    Application Scenarios of NSRH Blowers in the Chemical Industry
    2025-03-10
    NSRH blowers are widely used in various application scenarios within the chemical industry. These mechanical devices compress gases into high-pressure forms by cyclically compressing working media, enabling energy conversion and storage. Steam compressors play a critical role in chemical

    1. The instrument must be vertical: a 17mm wrench should be used to tighten it during installation, and the case should not be twisted strongly; Collisions should be avoided during transportation;2. The instrument should be used in the surrounding environment temperature of -25~55 °C;3. The vibrati

    The power required for the roots vacuum pump to compress the gas is directly proportional to the pressure difference, once the gas pressure difference is too high, the pump may be overloaded, causing the motor windings to burn out. There are several ways to solve the problem of pump overload:(1) Ado
