May I ask how to check the inlet and outlet pressure of the three blade Roots blower?

Checking the inlet and outlet pressure of the three blade Roots fan is an important step to ensure the normal operation of the fan. Here are some methods to check the inlet and outlet pressure of a three blade Roots blower:

Installation of pressure gauge: Install a pressure gauge on the inlet and outlet pipelines of the three blade Roots fan to directly read the inlet and outlet pressure of the fan.

Using a differential pressure gauge: Use a differential pressure gauge to measure the inlet and outlet pressure difference of a three blade Roots blower. Connect the two ends of the differential pressure gauge to the inlet and outlet of the fan, and the pressure difference can be calculated by reading the differential pressure gauge.

Observation instrument: Observe the instruments of the three blade Roots fan, such as vacuum gauge, pressure gauge, etc., to check the inlet and outlet pressure of the fan.

It should be noted that when checking the inlet and outlet pressure of the three blade Roots fan, it is necessary to first stop the machine and cut off the power supply to ensure the safety of the inspection. At the same time, it is also necessary to pay attention to the accuracy and precision of the pressure gauge and differential pressure gauge to ensure the reliability of the inspection results.

In short, checking the inlet and outlet pressure of the three blade Roots fan can help us understand the operating status of the fan, identify problems in a timely manner, and take corresponding measures to ensure the normal operation of the fan. Appropriate methods and management measures can be selected based on specific circumstances to ensure the normal operation of the three blade Roots blower.
