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
1. What is the limiting pressure for JZJLG vacuum pump units?
Depending on the specific configuration, the limiting pressure for the JZJLG series is either ≤1Pa (for single middle pump or standard configurations) or ≤0.1Pa (for units equipped with additional middle pumps like the ZJP series).
2. How do I select the correct JZJLG unit model for my application?
Model selection should not rely solely on standard series tables. You must calculate requirements based on your actual vacuuming process, gas release process, condensation of non-condensable gases, and variations in intake pressure over time, or reference existing system parameters.
3. What types of pumps are integrated into these vacuum units?
The JZJLG units are multi-stage systems combining a Main Pump (ZJP or ZJ series), an optional Middle Pump (ZJP series) for higher vacuum levels, and a Pre-stage Pump (LGB series) to handle initial exhaust.
4. What is the range of vacuum extraction rates available?
The series offers a wide range of extraction capacities, starting from 70 L/S (JZJLG70-1) up to 2500 L/S (JZJLG2500-4.2) to match different scale industrial operations.
5. How does the motor power requirement scale with the unit capacity?
Total motor power scales according to the pump sizes used, ranging from a minimal 7 KW for the JZJLG70-1 model up to 48 KW for the high-capacity JZJLG2500-4.2 system.
