    Automated grease dispensers

    Nivrah, that would depend completely on the application and bearing type and type of service. Spud says; Meticulous effort and willingness to learn are honorable traits.

    Hot-tap activity

    As you can see from the video the process is rather straight forward; I believe the velocity requirement is to prevent the posssibility of loss of cut out pieces. Spud says; Meticulous effort and willingness to learn are honorable traits.http://www.youtube.com/watch?v=_8_1dWktcbU

    Plan 13 seal running dry at Startup

    First, I must say I agree with pumps only. But your seal face material is suitible for a dry run, just as the manufacture states. I think you will be fine. Spud says; Meticulous effort and willingness to learn are honorable traits.

    Abrupt decrease in vibration on runup

    Critical speed. At certian RPM's some equipment, well all equipment has the tendency to flex and stretch causing it to vibrate. In a rotating equipment run up, if you are using VFD's or some other method of governing speed, one needs to push through known critical speeds quickly. Do not rest...

    Pipe Vibration

    Ask him what type of vibration he seems to be worring about, transmitted or inherent. In other words is he worried about vibration from background machinery at the facility or from the fluid/vapor flows themselves. It seems awful general this request of his. Spud says; Meticulous effort and...

    Thrust bearing location?

    Short question, long answer. Depending on the design of the pump is what determines the placement of the thrust bearing and type. Is it a 'balanced' pump? Does it pump hot fluids or nominal temp fluids? What types of pressures is the pump designed to generate? Thermal growth plays a huge...

    Automated grease dispensers

    We use Lubesite as well. Spud says; Meticulous effort and willingness to learn are honorable traits.

    Length of straight pipe before the suction of pump

    rmw, I agree completely, that falls under many strange things I have seen [pipe] Sometimes one really wonders what someone was or was not thinking. Spud says; Meticulous effort and willingness to learn are honorable traits.

    Automated grease dispensers

    We use both methods here. Automated greasing devices come in many types and designs and can be used for very small amounts of grease, (1 gram) Up to very large systems. It really dependes on what you want to spend on them. Spud says; Meticulous effort and willingness to learn are honorable...

    Knife Valves

    We use butterfly valves all the time in plants and they control energy just fine, and you can get many with self locking mechanisms to facilitate a proper lock out tag out. I personally would like to hear your safety committee's logic behind their reasoning. The amount of space of a knife...

    turbine ms 5001

    I recently left a facility that retired 3 1940's model GE 10MW units with Lynn standards. Great old units. Bullet proof and very dependable. The plant went on line in 48 and we shut her down in October of 2010. I have not seen a frame 3 in years and agree I do not think they are made...

    progressive HP rating in multi reduction gearbox

    I went and looked at the pics in the other thread of yours, I would agree with gearcutter. I would also ask, is this an Amarillo gearbox?

    Design Checking

    Not enough information. As drawn I agree with caomhin1. With out more specifics on what type of cam and what it does all I can say is that from a mechanics standpoint, it is job security.

    Length of straight pipe before the suction of pump

    The tendency to overthink things is common amongst all of us. In my many years as a pump mechanic on all types of pumps there are some things I have learned. The same pump used in any setting be it heavy industry, commercial/municipal is the same pump. It may get treated very differently in...
