The recommended frequency is once per month for High Pressure (40 bar) steam systems and daily for very high pressure (1000 bar +) steam systems. The main function of an over speed trip is to cut the fuel supply to the cylinders in case the engine speed rises above the pre-set level. Trip valve packing is essentially a filter that will trap any contaminants between the trip valve and the packing which can prevent the trip valve from closing. The speed sensors look at the measuring surface and give a sine or square wave signal, which the measuring system sees as pulses. It comes with a flexible work light, blade, parallel guide, miter gauge and hex key. This is normally accomplished with dump valves that re-route the feed stream from the turbine inlet directly into the condensers. 2 urethane Band Saw Table $ 85 ( Richmond ) pic hide posting Tm finish for precise blade tracking read reviews & get the Best deals - Sander, condition!

Now this turbine is extraction-condensing type turbine with the condensate of the condensing section going to the surface condenser. Centrifugal force resulting from high shaft speed will force the trip lever, which will allow the spring loaded handle to move inward. Installed on many gas turbines and reciprocating engines alike. When the over speed trip operates, the pin holding the steam stop valve in the open position is released, closing the valve and stopping the flow of both, the steam and the fuel. Exercising a trip valve regularly can mean the difference between a turbinetripping when necessary and catastrophic failure.
