Precautions to Take When Installing Centrifugal Explosion-Proof Fans and Laying Piping

Generally, precautions must be taken when installing centrifugal explosion-proof fans or laying piping. The primary goal is to prevent potential issues that may arise during future operation of the fans and to minimize malfunctions. We hope to assist you by providing a brief overview of this topic. Let’s take a look at the specifics. First, when selecting a fan, you should avoid choosing a centrifugal explosion-proof fan with a saddle-shaped performance curve. Specifically, this refers to a performance curve that lacks a lower-left portion. If this is not done, there is a tendency for future usage to increase sharply. Additionally, you should select a fan with a relatively low flow rate at high pressure points. This also helps prevent the aforementioned phenomenon. Second, the primary purpose of using a centrifugal explosion-proof fan is to maintain smooth operation of the unit. Therefore, the fan’s flow rate must exceed the surge flow rate. When operating the unit, we recommend using a dual-valve operation method. Specifically, install two valves on the fan’s discharge pipe and ensure the volume between the two valves remains constant. One valve can be configured as a throttle valve at the outlet of the centrifugal explosion-proof fan unit, while the other valve should be positioned away from the outlet to minimize operational noise emitted by the unit. Additionally, care must be taken to control the maximum current value to ensure it does not exceed the equipment’s maximum load capacity. If the maximum current value of the centrifugal explosion-proof fan can be appropriately reduced during operation, the unit’s protection will be more effective. Furthermore, it is necessary to regularly inspect and replace various equipment and instruments to ensure they are functioning properly. Otherwise, incorrect readings from indicators may affect the control system of the centrifugal explosion-proof fan unit, disrupting its normal operation and causing numerous issues.
