What aspects should be paid attention to when inspecting plunger-type metering pumps?
Vibration, static sealing, bearing temperature, etc.
There is also the sound of check valves, the oil level and quality in the oil reservoir, and whether water will get into the transmission box when it rains
Check for leaks in the packing seal, listen to whether the sound of the transmission mechanism is normal, listen to the sound of the check valve to see if it is functioning properly, check the pressure gauge to ensure that its readings are normal, and verify that the components used to adjust the stroke are tight; if they are loose, it may affect the flow rate of the medium. Also, check whether the lubricating oil is of good quality and free from emulsification issues... That’s about it
I’m sorry, I’m just checking to see if the check valve is working properly! Typed by mistake···
