What is the function of Bull gear in centrifugal compressor?
a bull gear is used as common driver for pinion gears that are installed on the shaft for each rotor.
What is a turbine barring gear?
When a large turbine rotor stops it will still be hot and will tend to bend in the middle if left to cool normally. To prevent this the barring gear will turn the rotor slightly at given intervals during the cool down period.
What are the main components that make up a helicopter?
Main rotor, tail rotor, drive shaft, engine and transmission, tail boom, cockpit and landing gear
Are the timing marks on 5.7l 1999 Chevy Tahoe Top Gear 6 o'clock or 12 o'clock and where is the rotor pointed to?
the top gear which is the cam gear should be at 6 o clock, the bottom which is the crank shaft should be in the 12 o clock position, your rotor should be aimed at the no 1 cylinder on your distribtor cap.
1977 silverado distributer rotor does not rotate?
Either the cam gear or distributor gear are completely worn out or the more probable. The gear on the distributor is installed using a roll pin. It's possible this is worn out and broken.
Steam turbine turning gear?
Steam Turbine Turning Gear - Turning gear is utilized on turbines to reduce eccentricity or out of round of the rotor. When a rotor is standing still it has a tendency to sag due to its weight. While running a turning gear which is a separate motor that turns the rotor slowly 10-50 RPM through a clutching mechanism. This rotation keeps the rotor in balnace. It is very important to run the turning gear on shutdowns and start ups. The time required to run is dependent on the size of your unit. Typically the turning gear must be on for 12-36 hours for small to large steam turbins after shutdown and 2-16 hours prior to a turbine start. If a turning gear is not utilized the rotor will become eccentric and may cause vibration up to wiping rotating parts with the stationary parts causing catastrophic failure. Steamengineer @ Gmail
How does a wind turbine operate?
The Wind Turbine Generator (WTG) is broadly divided into three parts. • Tower • Nacelle • Rotor The tower of wind turbine generator supports the nacelle and the rotor. The nacelle contains the key components of the wind turbine, including the gear box, the electrical generator, control panels etc. The rotor blades convert the kinetic energy of the wind to electrical energy through gear box and generator. The hub of the rotor is attached to the gear box. The gear box has a low speed shaft for its input. The high-speed shaft of gear box rotates at approximately 1500 revolutions per minute (RPM) to drive the electrical generator system. The heart of the wind turbine is its controller, which is responsible for the operation of the whole turbine. The embedded software in the controller monitors the various inputs and other condition and controls/actuates the outputs accordingly.
Does a 98 astro 4.8 have a distributor cap and rotor button?
Yes, while you are changing, check the distributor gear for wear, common issue.
Why does your Chevy s10 skip third gear?
Probably an ignition problem,start with replacing thespark plugs, spark plug wires, cap and rotor.
How do you set timing after it has moved timing chain broke?
Get a new timing set (crank gear, cam gear, chain) Install crank gear and turn crank so mark on gear is straight up. Loosely install cam gear, turn so mark on gear is straight down. Remove distributor cap, verify rotor is pointing at #1 plug wire. #1 is drivers side front cylinder. If rotor is 180 degrees out (pointing at #6 wire rather than #1) turn crank one full turn clockwise to bring rotor to #1. Marks on both gears should now be directly adjacent to each other, Crank mark up, cam mark down. Gently remove cam gear so as not to rotate cam. Install chain around crank and cam gear, being sure to maintain mark orientation. Bolt cam gear back in place. Check alignment of timing marks, if they are not right remove cam gear and try again. Torque to spec. Your engine is now at TDC #1 on compression stroke. Should fire right up.
Why car does not start and does not make clicking noise?
Dead battery, jammed starter rotor arm - it it's manual, put it in gear and then rock the car back and forth to un-stick the rotor arm. If it's the battery, main lights will be dim or not work.
How do you replace a front brake rotor on a 1994 Ford Explorer?
If it is of the "peel off" type Remove wheel Remove 2 caliper mounting bolts Slide and support caliper off the rotor Remove rotor should slide off If not "peel off" type Complete above steps and in addition Remove center hub (Spring Loaded) Remove gear should slide out Remove "spanner" nut Wiggle rotor outer bearing should fall out Remove Rotor
