Frequently Asked Questions
Q
What is the maximum suction rate available for the ZJQ series pumps?
The ZJQ series offers a maximum suction rate ranging from 300 L/S (ZJQ-300) up to 5000 L/S (ZJQ-5000), allowing users to select the appropriate model based on their specific vacuum system requirements.
Q
What is the limiting pressure for all ZJQ series models?
All models in the ZJQ series share a uniform limiting pressure of 15,000 Pa, ensuring consistent vacuum performance across the entire product line regardless of the model size selected.
Q
How is the motor power determined for a specific ZJQ pump model?
The motor power is not fixed — it is determined based on the actual working pressure difference of your application. Each model offers a range of rated power options (e.g., ZJQ-1200: 15～132 KW), and the appropriate motor must be selected according to the specific operating conditions.
Q
Does the working pressure difference affect water consumption?
Yes. The water consumption of the cooler varies depending on the actual working pressure difference. Higher pressure differences typically result in greater heat generation, which increases the required heat exchange area and water usage of the cooler.
Q
What are the operating speeds of the ZJQ series pumps?
The ZJQ series pumps operate at speeds between approximately 1,460 and 1,480 rpm. Specifically: ZJQ-300 runs at 1,480 rpm, ZJQ-600 at 1,460 rpm, and models ZJQ-1200 through ZJQ-5000 all operate at 1,470 rpm.
Q
How do I choose the right ZJQ model for my application?
Selecting the right model involves evaluating your required suction rate (L/S), the working pressure difference in your system, and the available power supply. Once these parameters are known, the appropriate model, motor power, and cooler specifications can be matched accordingly. It is recommended to consult with a technical specialist for precise configuration.
