Can anyone comment on the use of high pressure sodium (HPS) lights and use of them in conveyor tunnels. The tunnel has dust due to the products being conveyed. Products like coke, quartz, chromium oxide. Does the light have any affect on the dust or can an expolsion occurr. Will the light travel...
Could someone explain to me what is a flameproof, explosion proof and a non sparking motor.
How is each motor manufactured for the conditions above.
Thanks for the help.
I need to calculate the pulley diameter to reduce the conveyor belt speed to 40m/min. It has been a long time since I worked with the calculations.
Description of set-up: Motor running at 1470rpm transmits power from a 145mm pulley to a larger pulley of diameter 630mm. from here a gearbox with...
Any ideas were one can find information on the testing, inspection, usage and control of lifting equipment as is legally required by law?
ASME codes would be much appreciated.
Good day Colleagues,

Good day all,
The situation: A mag drive pump has been installed in the plant and is the bottoms pump for a vessel. The pump liquid is Ethane and condensate. On start-up of the pump the pump fails due to journal bearing failure. The bearing is contained within a silicon carbide sleeve which...
