Show compressed AIR AND electricity compressed air and electricity are the two new powers and are new fields for industrial du research electricity has advanced beyond compressed air in the industrial march as it has always had this strong point in its favor that an electric plant must be properly installed that certain fixed laws of science mut be respected in the installation of electric plants has been acknowledged by engineers tor for some time as the defective installation of electric equipment means that whon abon it is placed in operation a series of difficulties will follow that you will have short circuits 21 grounds rounds and burn outs of cf all kinds and it may even be a menace to human life with all of these difficulties confront confronting jug engineers they have learned to respect the laws of science that apply to this parti particular milar power with air power it is difficult for it is a safe power with which there have been too many unreliable experiments A combination of human nature business enter enterprise pris e and greed is somewhat responsible for the conditions we find about us which result in many points being overlooked overla aked by the prospective purchaser or actual user and quite as often being disregarded by the manufacturer either purposely or through ignorance first cost of installation in too many cases is made the paramount issue first a compressor of too small a size is ordered to this is added defect defective ire installation A receiver of unsuitable size and design is used the air is taken to the compressor in many cases through a duct leading from some room filled with dust and grit and to this is added a defective system of piping for transmitting the air to various places lor for different uses the pipes are too often carelessly laid down filled with sags and pockets and are of too small a size to transmit the air required for the work and considerable sid erable loss follows due to retardation by friction of the pipes an insufficient supply of cooling water is furnished by the water jacket for purposes in some plants all these faults exist and you will find the owner of them condemn ing the use of compressed air appliances and machinery and all because he has allowed his own false standard of economy to run away with his judgment and like many of the human family unwilling to admit that the fault is caused by his own bad engineering gi he seeks satisfaction by condemning the art we often of ten in air plants find that nearly all the rules and laws pertaining to the work of compressing to transmitting and to utilizing air power so simple that it doea not refuse to work although its efficiency may be cut down 50 per cent compressed air will exert the force that remains in the same safe way because unlike electricity it cannot resent the wrongs that have been thrust upon it in designing and installing a compressed air plant there are many rules and laws applying to the art that engineers should observe in order to procure economical and useful results from article compressed air and defective installation of air plants in mines and minerals for september |
