ⓘ
Explanation: The table represents the recommended standard series. Due to the varying working conditions in actual production applications, the intake gas and pressure will undergo many changes. Therefore, during the selection process, calculations should be conducted based on the actual vacuuming process, gas release process, condensation of non-condensable gases, changes in intake pressure over time, etc., or the selection should be made by referring to the usage conditions of existing equipment.

Frequently Asked Questions
Q
What does the limiting pressure value in the JZJLG series indicate?
The limiting pressure indicates the lowest pressure level the vacuum unit can achieve under ideal conditions. Models in this series are available with limiting pressures of ≤1 Pa and ≤0.1 Pa, allowing users to select the appropriate unit based on the vacuum depth required by their specific process.
Q
How do I choose the right JZJLG vacuum unit model for my application?
Selection should be based on your actual process requirements, including the required vacuum extraction rate (L/S), the target limiting pressure (Pa), the nature of the intake gas, gas release characteristics, and changes in intake pressure over time. It is also recommended to reference the operating conditions of existing similar equipment for guidance.
Q
What is the difference between the main pump, middle pump, and pre-stage pump in the unit?
The main pump (e.g., ZJP or ZJ series) handles the primary high-vacuum pumping. The middle pump acts as an intermediate booster stage, bridging the main pump and the pre-stage pump. The pre-stage pump (e.g., LGB series) is the backing pump that maintains the necessary inlet pressure for the upstream pumps. Units requiring deeper vacuum (≤0.1 Pa) typically include all three stages.
Q
Why do some models with the same extraction rate have different motor power ratings?
Models with the same vacuum extraction rate may differ in total motor power because they use different pre-stage pump configurations (e.g., LGB120 vs. LGB150 vs. LGB200). The choice of pre-stage pump depends on the specific process gas load and pressure range, which directly affects the power requirements of the overall system.
Q
Can the standard JZJLG series configurations be customized for non-standard working conditions?
Yes. While the table lists recommended standard series configurations, actual production environments often involve variable gas compositions, fluctuating intake pressures, and condensation of non-condensable gases. In such cases, a customized selection or system design is recommended, taking into account all relevant process parameters to ensure optimal performance and reliability.
Q
What industries or applications are JZJLG vacuum units typically used for?
The JZJLG series vacuum units are widely used in industries that require medium to high vacuum environments, such as vacuum metallurgy, chemical processing, pharmaceutical manufacturing, vacuum drying, vacuum coating, and electronic component production. Their multi-stage pump configuration makes them suitable for processes with demanding vacuum depth and high gas throughput requirements.
