When installing the stator of the screw pump, it is important to ensure the correct installation direction, which is essential for the normal operation of the pump and to extend its service life. Here are the key steps and precautions in the installation process：

‌

1‌.Preparatory work ‌ :

Before installation, thoroughly check the internal structure of the screw pump to confirm that the rotor, stator, sealing ring and other components are intact.

Clean the inside of the pump and dry it thoroughly to keep it dry.

‌ 

2.Apply lubricating oil ‌ :

Apply an appropriate amount of lubricating oil or recommended lubricating material evenly inside the stator to reduce friction between the stator and the pump housing and improve the efficiency and service life of the pump.

‌ 

3.Determine the installation direction ‌ :

Ensure that the stator installation direction can be smoothly inserted into the pump housing, and good fit with the rotor.

Follow the pump design requirements to ensure that the stator rotation direction is consistent with the overall rotation direction of the pump.

‌

4.Gap check ‌ :

Use a micrometer or vernier caliper to accurately measure the gap between the stator and the pump housing to ensure it complies with standard specifications.

Maintain proper clearance to prevent overheating or damage during operation.

‌

5.Sealing test ‌ :

After installation, perform a tightness test to ensure that there is no leakage.

The sealing effect can be verified by applying slight pressure and observing for leaks.

‌ 

6‌.trial run ‌ :

Carry out no-load test run to check whether the running state of the pump meets the technical requirements.

Pay special attention to monitor whether there is abnormal sound or vibration, once found abnormal should immediately stop to check.

‌ 

       Following the above steps and precautions can ensure the correct installation of the stator of the screw pump, thus ensuring the efficient and stable operation of the pump. If you encounter any problems during the installation process, it is recommended to consult the user manual of the screw pump or consult a professional technician for help.
