Hi everyone. I would like to consult for a blower that was recently repaired? I would appreciate any help on this. Attached document is my initial investigation of the blower and hopefully you may take time to read this. On the last pages of this presentation are only my suspicion. I haven't...

Hi Johnny Pellin. I notice also that the belt of the blower during operation has a higher tension than expected during my trial. I didn't mind it as I thought it was just normal. I think your theory is also one to consider. Operation would reason to me that it has been that way ever since and...

Hi again everyone... Is it also possible that the back pressure due to blockade or restriction of flow can really snap all of the 14pcs Allen Cap Screws of the drive shaft and also ending up cracks on the body of the blower as well as gear head plate and drive head plate? I can't help but think...

By the way the lobes were already re-built via puddle torch (Spray and fused) and was fused perfectly. It may appear on an irregular shape and finish but clearances were acceptable...I tried to upload a video but couldn't send it due to errors showing on this site... Thank you for any comments...

Hi Everyone. Thank you for taking time and sharing your thoughts about my project repair for Whispair Roots Blower. I forgot to include in my report that on the 1st and 2nd trial during operation of this blower we decided not to couple the discharge port to the silencer and operate this with...

Hello everyone. I would like to consult what piston material will be better for application of hydraulic cylinder used for ship un-loader. I thought of using AISI 1045 / AISI 1050 for this. Will this be fine? This cylinder is pressure tested to 350bars but operates only up to 250 bars. Cylinder...
