There is no fixed value for the suction pressure of a steam ejector, as it is influenced by a number of factors, including the design of the steam ejector, the operating conditions, and the vacuum level required. However, based on the information in the reference article, we can give some points and reference ranges related to inhalation pressure:
Design pressure
The design pressure of a steam ejector determines the minimum limit of its suction pressure. If the steam pressure falls below this design limit, the evacuation of the steam ejector will be less effective and may not even work properly. As mentioned in Article 1, the appropriate range of steam pressure at the inlet of the ejector should be between 0.3~0.7 MPa.
Effect of steam pressure
The steam pressure will directly affect the suction pressure of the steam ejector. Higher vapor pressures help to improve the effectiveness and efficiency of vacuuming, but excessive pressures can also cause damage to equipment. Therefore, when choosing the steam pressure, it is necessary to consider the balance between the bearing capacity of the equipment and the working efficiency.
Equipment requirements
Different equipment has different requirements for the suction pressure of the steam ejector. For example, some equipment may require a higher vacuum level, so a steam ejector with a higher suction pressure needs to be selected. For some equipment that does not require a high level of vacuum, you can choose a steam ejector with a lower suction pressure.
In summary, the suction pressure of the steam ejector needs to be determined according to the specific equipment requirements and operating conditions. In practice, it is advisable to refer to the technical specifications and parameter requirements provided by the equipment manufacturer to ensure that the steam ejector can meet the required suction pressure and vacuum requirements. At the same time, it is also necessary to pay attention to the selection and regulation of steam pressure to avoid unnecessary damage to the equipment or reduce work efficiency.
