6·5设计举例例1 氨压机能量调节氨压机的能量调节除采用定型产品“能量调节(?)”外,对于能量级数不多的系统,也可通过继电线路来实现。例如:某一个系统有几台氨压机,每台机又有几级能量,共 N 级能量。根据工艺要求,在几台氨压机吸入管道上(或低压循环贮液桶上),装有上下限的接点压力表,如压力在上下限之间则为能量正常,不进行增加或减少能量。如果压力高了,上限接点动作则表示能量不够,经一定时间后增加一级能量,如上限接点仍动作,经上述延时后,再增加一级能量。
6.5 Example of Design Example 1 Ammonia press energy adjustment Ammonia press energy adjustment In addition to using the stereotype product “energy adjustment (?)”, For the energy level of the system, but also through the relay line to achieve. For example: a system of several ammonia press, each machine has several levels of energy, a total of N-level energy. According to the process requirements, in several ammonia pressure on the suction pipe (or low pressure circulating liquid storage barrel), with upper and lower limits of the contact pressure gauge, such as the pressure between the upper and lower limits for the energy is normal, without increasing or decreasing energy . If the pressure is high, the upper limit of the contact action means that the energy is not enough, after a certain period of time to increase an energy, such as the upper limit of contact is still action, by the above delay, and then increase the energy level.
