AI Technical Summary
Existing pumps are prone to fluid leakage when pressure is unbalanced.
A check valve and a pressure switch are installed at the outlet pipe. The impeller's working state is adjusted by monitoring pressure changes in real time. Combined with the symmetrically designed installation pipe and the use of the check valve, the unidirectional flow of the medium and the stable pressure are ensured.
It improves the stability and safety of the pump body, reduces fluid leakage, enhances working efficiency and reliability, and extends service life.
