THIS GUY IS NOT A MECHNANIC. HES JUST A ROBOT. HE DIDNT STUDIED MECHNICS, HE DONT KNOW WHAT HES DOING. HE RELLY NEEDS TO STUDY MECAHNICS TO HAVE THE MECHANIC EYE. A RELA MECHNIC WORTHS MANY DOLLARS...ROBOSTS ARE JUST CONVENIENT WORKERS, GOOD LUCK EMPLOYING PEOPLE WITH NO MECHANIC KNOWLEDGMENT.

No wear rings in your pumps? why no mention of clearances b/w impellor and casing. ?

@DESMIAS 5 жыл бұрын

Yes - the NSL pump has wear ring(s). Please refer to actual pump manual regarding acceptable clearance.DESMI pump manuals are found here: www.desmi.com/centrifugal-pump-manuals.aspx

What do you call the material handling set up you have with remote control for moving the pump?

@DESMIAS 2 жыл бұрын

We use a remote-controlled crane by the workstation. Other options could work, as long as safety, weight and mobility and is taken into consideration and in place :-)

When fitting the impeller back over the shaft, does the mechanical seal shaft spring get compressed down over the keyway?

@DESMIAS 5 жыл бұрын

Yes :-)

Some of our brand new Desmi vertical pumps impellers are rubbing against the housing when turning the pumps shaft with hand. Any suggestions? We have a lot of Desmi Pumps in the warehouse to be installed on the ship in future. Thanks

@DESMIAS 3 жыл бұрын

Please check/ensure that the pump casing is not overloaded with forces / moments from the piping system - this might deform the pump casing and result in impeller rubbing against wear ring(s)

@@DESMIAS Thanks for the info. Will email desmi@desmi.com. No the pumps are not installed yet and it is in the warehouse for long term storage for 6 months to a year before they get installed on the ship. Part of the storage maintenance is to turn the pump shaft once a month. When turning with hand you can feel some of the pumps impeller is touching the housing.

Why didn’t check for shaft run out?

See 5:18 where we mention "check the shaft for damages" :-)Have a great day.

@rahimys6135 5 жыл бұрын

Yes i know you check the shaft for damages but should check shaft with dial indicator to determine whether the shaft is bend or not..that’s what i mean..if the shaft using component or cartridge seal, always check stuffing box perpendicularity and concentricity to ensure it’s still within tolerance to avoid seals premature failure..thanks..have a good day..

Could someone please clarify to me why the bearings had to be heated?

@DESMIAS 6 жыл бұрын

Hi A. Specter - thank you for your comment. The bearing is heating for easy mounting on the shaft.For more information, please do not hesitate to contact us at desmi@desmi.com

Can anyone please tell me what is the exact name of that Coupling.

@DESMIAS 3 жыл бұрын

This pump does not use a regular coupling. Our model A02 is designed with a short motor bracket frame which means that we use a kind of pipe coupling which is fitted directly at the motor shaft. This design also eliminate the requirements of pump bearings.

what kind of coupling is it ?

Hi David. The easy answer is Monobloc Coupling and this of course comes in various sizes. You can read more about the NSL pump and the coupling here: www.desmi.com/desmi-products/nsl-centrifugal-pump.aspx
