Book Description
Excerpt from British Progress in Pumps and Pumping Engines Where little power is required, hot air engines are quite in place for powers up to about I horse-power, they are very economical and require but moderate attention. Such motors would often prove the best in country man sions, in farms and under Similar conditions. Compressed air is a valuable source of motor power. It can be carried in pipes for considerable distances with out appreciable loss of pressure, always provided that the air compressor is of the right design and construction; otherwise the loss of power and the cost of compression are apt to be very heavy. Electric motors are coming more and more to the front for pumping purposes, but an essential condition for the use of such power is this, that current is available at a reasonable cost. The advantages under suitable condi tions of electricity are obvious. It is always ready no time is lost in starting there is no condensation of steam. No doubt users of electric power have their own troubles. If the diameter of the cable be too small, or if there are too few strands, there will be a very sensible loss of power, while with too large a cable the first cost will be excessive. But if a cable of suitable diameter be selected, the waste of power will be trifling. Where an electric motor is used three-throw single-acting pumps are the best, as these give a more even distribution of power, which is essential in electric driving.

Book Description
Excerpt from Pumps and Pumping Machinery The author does not think it necessary to enter into a history as to the first use of the ordinary pump, lift and force pumps of the usual type for domestic supply are now so well known that no notice need be taken of them. Descriptions of machinery at work, derived in most cases (except in some specially mentioned) from his own practice and experience are given. He would like it to be understood, where any data are given, especially as to the performance of machinery of any kind, that they may be taken in all cases as good average results, and not mere experiments. Dimensions are given of the leading apparatus connected with pumping machinery and plant, as well as various types of engines and boilers, to indicate to those who have not had much experience in this class of work what they should specify in stating their wants. The author hopes it may prevent in future, to some extent, the issue of the crude specifications and drawings that are too often seen, especially as they place contractors who tender for the work in an unfair position. Where so much is left to their own ideas, it necessarily follows that the tenders are very wide as to price. In the present day, when the lowest tender is usually accepted, it is necessary to have all the details of a proposed work clearly defined, especially as to the leading dimensions and way of finishing the work.
