Vital Chemicals for Cooling Towers

Written by Thomas Yoon


Continued from page 1

Micro organism growing in cooling tower water causes a lot of problems. Clumps of algae can cause chokages inrepparttar pump strainers. Long strands of microscopic plants can act like nets that can cause restrictions torepparttar 133415 flow ofrepparttar 133416 water. Some organisms cause diseases and other health related problems to people. A typical biocide contains Sodium hypochlorite with concentrations ranging from 10 - 20%. Again, this is further diluted when mixed withrepparttar 133417 cooling water.

Even withrepparttar 133418 dosing of chemicals,repparttar 133419 cooling tower needs to be cleaned every now and then. Dusts fromrepparttar 133420 air still manage to settle down insiderepparttar 133421 sump ofrepparttar 133422 cooling tower. So does repparttar 133423 remains of dead micro organisms. These can stick torepparttar 133424 infills and preventrepparttar 133425 proper distribution ofrepparttar 133426 water flow.

Sometimes cooling tower plastic infills get brittle due torepparttar 133427 exposure to ultraviolet rays found in sunlight. They often break up into small particles that can choke even coarse filters.

Folks, it's time to clean up!

The cams ofrepparttar camshaft drivingrepparttar 133414 fuel pump can be adjusted to advance or delayrepparttar 133415 fuel injection torepparttar 133416 engine cylinder. The cams drivingrepparttar 133417 push rods forrepparttar 133418 inlet and exhaust valves can also be adjusted.

In doing all these adjustments, care must be taken to considerrepparttar 133419 positions ofrepparttar 133420 piston relative torepparttar 133421 process to be adjusted.

The flywheel atrepparttar 133422 end ofrepparttar 133423 crankshaft is usually marked as a reference to showrepparttar 133424 piston at Top Dead Center. Each piston will have its marking onrepparttar 133425 flywheel. Ifrepparttar 133426 engine has 6 cylinders, then 6 markings for Top Dead Center will be marked.

Fromrepparttar 133427 markings onrepparttar 133428 flywheel a person can refer to it for adjustments onrepparttar 133429 fuel pump cams, and cylinder valve cams.

Some diesel engines do not have inlet and exhaust valves. Perhaps we will look at 2-stroke and 4-stroke diesel engine next...

Well folks, start your engines.
