4 Considerations for avoiding cavitation

In order to avoid discrimination, liquid oxygen often has a degree of supercooling when entering the pump, so as to reduce the possibility of liquid vaporization in the pump. If the inlet pressure of the liquid oxygen pump is increased, the saturation temperature of the liquid oxygen will be increased and the liquid oxygen will have a certain degree of supercooling. Generally, the installation position of the liquid oxygen pump is lowered to increase the inlet pressure of the liquid oxygen pump (even if there is a certain static head at the inlet of the liquid oxygen), and the degree of supercooling is improved (the degree of supercooling is considered to be 6 ℃~10 ℃ in the design). For example, when the pressure of liquid oxygen in the main condenser evaporator is 0.04MPa, its saturation temperature is 94K. When the inlet pressure of liquid oxygen pump increases to 0.09MPa due to the static pressure of the liquid column, its saturation temperature is 97K, which is equivalent to that liquid oxygen has obtained a supercooling of 3 ℃. In addition, attention shall be paid during operation: the liquid oxygen adsorber shall be thoroughly precooled before startup until the liquid is discharged; Do not rush to close the bypass valve. Once cavitation occurs, exhaust immediately to ensure safe operation of the liquid oxygen pump. In order to improve the anti cavitation ability of liquid oxygen pump, the method of installing spiral or axial flow inducer in front of the working wheel is currently adopted in the structure to "remove the middleman outside and remove the thermal insulation wall inside". This is Zhang Ruimin's brief summary of organizational structure adjustment. The thermal insulation wall is the middle manager. Citing the words of Charles Handy, a management master, he said, "The middle layer of an enterprise is a group of roasted geese. They have no nerves and will not reflect the market situation. According to Haier's plan, Haier cut about 26000 jobs last year and this year.



For many years, household appliances belong to large-scale manufacturing and labor-intensive industries. Many household appliances are produced by manual assembly, which requires not only a large number of front-line industrial workers, but also production management personnel for management. According to Xu Feng, in the traditional production link, the ratio of workers and management posts is 1:10, that is, 10 workers are equipped with a management post. If the team leaders of the front line are included, the ratio can reach 1:5. Previously, in industries with high degree of automation, such as automobiles and FMCG, one worker may manage one line, and the number of management personnel is also greatly reduced. The ratio of 1:20 management posts is a common level of allocation.



Today, the transformation and upgrading needs facing the household appliance industry are not only Haier, but also Gree, Hisense and other household appliance enterprises have invested a lot of money in automation transformation. For enterprises, this may be the optimization result of reducing costs and improving efficiency. But for employees, this year's jobs may be "optimized" tomorrow, which is not only a reality faced by front-line industrial workers, but also the management. According to Xu Feng, in the production and manufacturing process, generally speaking, ordinary industrial workers are the first to be eliminated, followed by ordinary technical workers, senior technical workers and technical personnel managers.
一：触摸屏的参数。查看一下触摸屏的参数设置

这里面有几个参数需要特别注意的：

1：通信口的设置－－－一定要确认清楚PLC连接触摸屏的COM1口还是COM2口

2：设备类型－－－这个是0重要的，如果协议没选对的话，其他就不用说了

3：连接方式－－－PLC跟触摸屏的连线，确认好事RS485，还是RS232C

4：接口参数跟PLC站号－－－一定要跟PLC里面的设置一致。



二：如果参数确认设置好了，接下来就排查线路的问题

确认RS485,RS232C的做线是否正确，触摸屏与各种PLC接线的做法不一样。这个可以参照维控(plc与触摸屏通信线接法帮助文档）查看，这个是正常排查通信问题的基本方法。



接下来教大家如何绕开触摸屏的问题－－－在线模拟。在通讯不上的时候，有的客户会猜测可能是触摸屏的问题，或者接口的问题。在线模拟就是绕开触摸屏，直接用PLC跟电脑进行连接。
具体的做法：
这样子做就可以很明显查看PLC能不能跟PC通信上。如果可以通信上就可以排除PLC方面的问题，跟参数设置的问题。

在短短数十年间，计算机科学与技术取得了突破性的进展，并且广泛应用于多个行业之中，同时，在行业发展过程中，也将计算机科学与技术的应用效果与质量作为一项重要衡量指标。在教育领域中，计算机科学与技术作为一种有效的教学资源，有助于提高教学质量以及教学管理效率。在课堂教学中应用计算机科学与技术，有助于提高学生的学习积极性，为培养“互联网+”时代下的新型人才打好基础。在社会的发展过程中，计算机科学技术的发展具有十分显著的影响力，科学技术是社会发展的0生产力，对提升人们的生活水平具有十分显著的应用价值。处于信息技术高速发展的时代中，各行各业都对计算机科学与技术进行了合理运用，尤其是教育领域计算机科学与技术的应用具有十分显著的效果，但就现阶段的初中教学工作而言，教师未能合理利用计算机科学与技术展开教学工作。

一、初中计算机科学与技术现代化应用中存在的问题

（一）缺乏计算机科学与技术的现代化应用意识在信息化技术快速发展的背景下，人们的生活与计算机科学与技术之间存在密不可分的联系，将计算机技术应用在初中教学工作中是未来发展的必然趋势。但就目前的初中教学实际情况而言，学校对计算机科学技术的现代化运用缺乏重视，计算机一周只设置一节课程，而计算机是具有较强应用性的学科，学校的课程设置无法满足学生进行实践操作的学习需求，导致学生对计算机科学与技术的学习依然局限于理论知识。其次，大部分家长更重视学生的学习成绩，忽视了学生学习计算机科学与技术的重要性[1]。

（二）计算机科学与技术在教学与管理中缺乏普遍性

在初中教学过程中，现代化教学与管理必须以计算机为依托，但在实际教学中，大部分初中教师依然使用传统教学模式，无法在教学过程中合理应用计算机资源与教学手段，导致课堂教学内容枯燥、乏味，学生不能积极主动地投入课堂学习中，并且在教学管理中也未能妥善应用计算机科学与技术。

二、初中计算机科学与技术的现代化应用策略

（一）建立现代化教学管理体系
