Product Introduction

The Ht Series Pipeline Booster Pump Water Flow Switch Uses A Water Flow Type Magnetic Control Device To Control The On-off Of The Sensing Element To Achieve The Function Of Starting And Stopping The Water Pump.

Working Principle

The Water Equipment Is Opened, And A Water Flow Flows In The Pipeline, And The Water Flow Impulsively Rotates The Sensing Door Along The Flow Direction Of The Rotating Axial Water Flow, And The Magnetic Control Device Rotates Together With The Rotating Shaft, And When It Reaches A Certain Position, The Sensing Element Is Triggered, The Switch Is Turned On, And The Household Pipeline Is Pressurized. When The Water Flow Is Interrupted With The Water Equipment Shut Down, The Induction Door Rotates The Shaft And The Magnetic Control Device To A Certain Position Under The Action Of The Reset Bomber, And The Induction Failure Switch Is Broken, And The Pipeline Booster Pump Stops.

Water Flow Switcg Use Precautions:

1.During Installation, Pay Attention To Whether The Water Flow Direction Of The Pump And The Water Flow Switch Are The Same. The Arrow On The Water Flow Switch Points To Indicate The Direction Of The Water Flow Switch.

2.When There Is Impurity In The Water Pipe, It Will Cause The Water Flow Switch To Malfunction. Therefore, It Is Recommended That The Newly Installed Pipeline Be Flushed Out Of The Pipeline Due To Sufficient Physical Discharge Before The Pump And The Water Flow Switch Are Connected. It Is Recommended To Install The Filter In The Pipeline. But The Filter Should Be Cleaned Frequently To Avoid Water Flow Blockage And The Flow Rate Is Reduced, Causing The Switch To Start Failing.

3.When The Tap Water Flow Is Insufficient Or Unstable, The Water Flow Switch Will Turn Off When The Water Switch Is Turned On, And The Phenomenon Will Disappear When The Tap Water Flow Returns.

4.The Water Flow Switch Must Be Installed Horizontally On The Water Outlet Of The Pump And Cannot Be Installed Vertically.

5.the Two Wires On The Switch Are Connected In Series In One Of The Lines Of The Circuit, Regardless Of The Zero Fire Line. Unclear Customer Service Or Watch The Video. Thank You For Your Cooperation.
