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.

Rod and piston assembly for a clark tcv12. We are Installing three back into the compressors they came out of after they were rebored. We have been working on them for about 2 months now .it has been a major project at Williams and I have learned alot about it bieng that I have been on it since the start we we finished installing the valves and unloaders today and will torque everything to spec tommorow .
This weeks hours 40 class and work at internship
