我们在Z80计算机上用CBASIC语言编制了一个往复活塞式压缩机的热力及动力计算程序,力求做到通用性强、精度高和使用方便。下面讨论程序中的几个问题。一、分缸计算热力计算中,根据已知条件求出各级的行程容积V_(ti)是容易的。(除另有注解者外,本文所用符号均与[1]同义)但是,某一级的行程容积V_(ti)并不总是全部分配给一个单作用气缸,可能分配给同列(即双作用)或不同列的若干个缸。这时,分配的比例要使整机各缸不矛盾,或称为各缸相容。如果在复杂的情况下,有若干个级的行程容积都要分配到若干个缸去,互相穿插,则出现两个问题:即设计人员所作的气缸排列方案是否能使各缸相容和如
We have compiled a thermodynamic and power calculation program for a reciprocating piston compressor on the Z80 computer in the CBASIC language, with the aim of achieving universality, precision and ease of use. The following discussion of several issues in the program. First, the sub-cylinder calculation Thermodynamic calculation, according to known conditions to find the stroke volume at all levels V_ (ti) is easy. (Unless otherwise noted, the symbols used in this document are synonymous with [1].) However, the travel volume V ti for a given stage may not always be assigned to a single acting cylinder and may be assigned to the same column Role) or a number of different columns of tanks. At this time, the proportion of distribution to make the whole cylinder is not contradictory, or known as the cylinder compatible. If, in a complex situation, there are several stages of stroke volume to be assigned to several cylinders, interspersed with each other, there are two problems: whether the cylinder arrangement made by the designer is compatible with each cylinder and
