International Automotive Technicians Network is powerful info

ship from south Africa we loaded turbines on to

!20 ton Crane at the port in Esberg Denmark loading gear heads from a wind turbine Marks father Bjorne operates it .

Steam turbine has 520 k hp

Setting the load onto the ship

Raul next to 9-t used to push coal into the hopper at Dong Energy

This is a wind turbine erector ship at the port in Esjberg Denmark

International Automotive Technicians Network .The more knowledge you have the better.I also enjoy reading David Lieghton' s post of the Whatcom chief .David is one of the fortunate ones in our class .He has had the opportunity to work on different engines and is exposed to many scenarios where it takes allot of thought to be able to pull the engines out of very confined spaces.I guess I have been fortunate because at Williams there is definitely space around the engines that is one of the reasons I have decided to focus on stationary engines.Iam a big guy who probably would not fit in the engine room of a sailboat like the Aqavit where David worked on the Perkins engine last week.I really enjoy reading his post.Thanks for the great info David keep up the Good work. Last week I finished up installing the side doors to the compressors on number six engine while my co worker changed the oil filters on the Clark tcv 12 which has over a hundred of them .I worked on my electrical panel and auto schematics .I worked total class room and internship 40 hours

Electrical ( 40 hours class and intership )

Slowly but surely the electrical will sink in. Last week was a definite challenge as we worked on wiring the test boards .I must say it is critical to learn the diagram and symbols before you proceed to the board .On the job at Williams last week I helped reassemble the Clark compressors we torqued up all the bolts holding the caps on the compressor and gear heads that attach to the rods and pistons of the compressors using the star pattern and required torque specs I also started assembly of the tubing for monitoring the compression in the compressors. and greased the valves in and around the meter station.I have been very fortunate to have a great pair of journey man mechanics such as Brandon and Theason to teach me at Williams pipeline next week we will finish the job and go on to new and exciting challenges hope you all are having fun. have a great week.

dc motors

Direct-current motors transform electrical energy into mechanical energy. They drive devices such as hoists, fans, pumps, calendars, punch-presses, and cars. These devices may have a definite torque-speed characteristic (such as a pump or fan) or a highly variable one (such as a hoist or automobile). The torque-speed characteristic of the motor must be adapted to the type of the load it has to drive, and this requirement has given rise to three basic types of motors: 1. Shunt motors 2. Series motors 3. Compound motors Direct-current motors are seldom used in ordinary industrial applications because all electric utility systems furnish alternating current. However, for special applications such as in steel mills, mines, and electric trains, it is sometimes advantageous to transform the alternating current into direct current in order to use dc motors. The reason is that the torque-speed characteristics of dc motors can be varied over a wide range while retaining high efficiency. Today, this general statement can be challenged because the availability of sophisticated electronic drives has made it possible to use alternating current motors for variable speed applications. Nevertheless, there are millions of dc motors still in service and thousands more are being produced every year.
