    a system to measure drilling mud level- testing rig

    Is it possible to put a weighted plate on top of the mud or in a baffled section of the tank where the baffle is at the top rather than the bottom and as the plate goes down to a particular depth a switch is engaged by the weight of the plate or triggering mechanism to a limit switch giving you...

    Oil with higher viscosity

    Does the compressor make "life". Does it achieve the required hours or does the unit fail before hand? Does the unit run cooler with the more expensive oil or the same as the oem product. Is the unit pressurised before start up? Direct drive lube pumps are all that effiecent until there is head...

    rescue system for user of fall arrest underground mining equipment

    The problem you will have here would be that Temporary basis would then become permanent because management says "it works".There are a few design rules here that would probably clash with the idea of using the winch/ratchet.If someone was using a fall arrest system and was in need of rescuing...

    Help nobody knows what their talking about multi control feed system

    Why not run a pressure compensated variable piston pump with an adjustable bleed off line from the compensator.This system would require it to be closed loop and a small cooling valve.When you are operating the pump to come onto stroke the variable restrictor would be wide OPEN.And when you...

    overheating hydraulics

    Your description is too vague.What seals are being damaged?At the relief,the whole system?Do you run oil coolers?A cooling control valve(thermostat)?Working components?Describe your system in detail along with all info on problem ,supply hyd.schematic?And an educated logical approach can be...

    why scrape sleeve bearings?

    scraping bearings arent usually done anymore in this throw away and technologically advanced world.It was done to remove high spots that had the potential to score a journal,and promote excess wear.Pretty much any irregularity from the manufacturer when it came to plain bearing scraping was...

    Anti-Collision Detection on a Mining Unit

    Distance meters that builders/carpenters use in their tade can be used along with a cheap detection system from an electronic shop can be made for what you need,as the system is manually controlled the operator can keep an eye on any variation and adjust accordingly.Played with this years ago it...

    reducing energy consumption in the mine

    Some are more obvious than others,examples would be solar energy in newly built buildings (maximising the sun in relation to building design, heating and power supply).More efficient mining equipment(electric over diesel)Pressure sensitive pads in hall ways store rooms etc. to turn lights on for...

    Corner break in Anodized spool valves in transmission control

    What temps are you running? Is the bore of the sliding spool also coated? Is it that the thermal expansion is creating the problem?How about the filtration? Im only throwing out ideas maybe something you missed? Can you do trials where an alloy spool is used?Or a steel bore?An over length spool...

    mixing water with compressed to make spray

    Sure can have been doing it for years.you can actually buy spray nozzles to do this job but think the water is at a lower pressure so it can be picked up in a venturi type effect,alternatively you can "mix" right at the valve if you like.Agricultural hardware shops have stainless steel sprayers...

    Case Drain Flow?

    Its a pain when you dont have all the info made available to you when planning things but typically CD is around 10% of total displacement.Temperature is a great indicator of wear I would suggest a variation of more than 5 degrees on a component from a system would be an indicator of increasing...
