    1. Positive Pressure and Negative Pressure2. Relative Pressure and Absolute Pressure3. Vacuum Degree4. Methods of Pressure Representation5. There are two ways to express pressure: one is the pressure expressed with absolute vacuum as the reference, called absolute pressure; the other is the pressure

    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

    1. Installation siteThere should be a safe passage position no less than 1.5-2 meters around the fan. The operating ambient temperature of the fan shall not exceed 40 degrees Celsius. When the fan is installed indoors, it should ensure that the machine room has sufficient lighting, dry air and good
