Disassembly and maintenance of flowmeter operating procedures
First, the maintenance flow meter operating procedures:
Close the entrance gate → close the exit gate → vent flow meter internal pressure → split flow meter core → check the flowmeter chamber with or without debris → check the core rotation → clean the flowmeter chamber → install the core, try to rotate → open Outlet valve → open the inlet valve → observe the flowmeter speed, until the normal operation → clean up the tool, clean up the scene.
Second, the maintenance flow meter risk tips:
1, electric shock: personnel after the electric shock, immediately shut down the relevant power supply or the injured from the power supply, and then the ambulance for the injured, serious to the hospital
2, mechanical damage: the occurrence of mechanical injury, immediately to the injured from the source of injury, emergency wraps sent to the infirmary treatment.
