GMP洁净车间很多都不合格是为什么?

1、工程设计不合理。
1. Unreasonable engineering design.
一般来说,工程设计不合理这个现象很少出现,出现这些个问题的往往是一些小型的对于净化要求的不太高的项目上。现在做净化的厂家非常多,竞争也是越来越激烈,有一些建设企业为了中标所以给出的报价非常低,在后期的施工中,利用对方客户不懂的情况,偷工减料,当然这只是一个方面,另一个方面是设计施工开始后,客户那边又增加了新的要求和净化区域,使原有的设计无法满足要求。这些先天缺陷难以纠正,应在工程设计阶段避免。
Generally speaking, the phenomenon of unreasonable engineering design rarely occurs. These problems often occur in some small projects with low purification requirements. Now there are many purification manufacturers, and the competition is becoming more and more fierce. Some construction enterprises offer very low prices in order to win the bid. In the later construction, they use the situation that the other customers don't understand to cut corners on work and materials. Of course, this is only one aspect. On the other hand, after the design and construction began, the customers added new requirements and purification areas, The original design can not meet the requirements. These congenital defects are difficult to correct and should be avoided in the engineering design stage.

2、用低价产品替代产品
2. Replace high-end products with low-cost products
在洁净室过滤器的应用中,国家规定净化10万级以上的空气净化应采用初、中、过滤器三级过滤。由于连续的大型净化项目使用亚空气过滤器代替万级净化的空气过滤器,清洁度较差。更换了过滤器,满足GMP认证要求。
In the application of high-efficiency filters in clean rooms, the state stipulates that primary, medium and high-efficiency filters should be used for air purification above 100000 levels. As the continuous large-scale purification projects use sub high efficiency air filter to replace the high efficiency air filter of 10000 level purification, the cleanliness is poor. Finally, the high efficiency filter was replaced to meet the requirements of GMP certification.

三、送风管或过滤器密封不严。
3、 The air supply pipe or filter is not tightly sealed.
这种现象是由于施工粗糙造成的,表明某些房间或同一系统的某些部分在审批时不符合条件。一种改进的方法是对供气管采用光泄漏测试法来检测泄漏并使用过滤器。扫描粒子计数器测试部分、密封粘合剂和安装框架以定位泄漏并仔细密封。
This phenomenon is caused by rough construction, indicating that some rooms or parts of the same system do not meet the conditions at the time of approval. An improved method is to use the light leakage test method to detect the leakage of the air supply pipe and use the filter. Scan the particle counter test section, sealing adhesive and mounting frame to locate the leak and seal carefully.
四、回风管道或回风口设计调试不当。
4、 Improper design and commissioning of return air duct or air outlet.
在设计的时候,有的客户那边的空间不是太充足,所以就导致上送风侧的回风或回风口存在数量上的不足,这就导致车间没有办法使用,所以在设计GMP洁净车间的时候,不管空间大小一定要注意这一点,当然在排斥了设计原因以后,回风口的调试也是很重要的的一个环节。如果调试有问题,回风口阻力过大或者过小,都会导致回风量小于或者大于送风量,那么清洁度是肯定不能达标的。
When designing, some customers don't have enough space, so there is a shortage in the number of return air or return air outlets on the upper air supply side, which makes the workshop unable to use. Therefore, when designing the GMP clean workshop, we must pay attention to this regardless of the size of the space. Of course, after excluding the design reasons, The commissioning of air return outlet is also a very important link. If there is a problem in commissioning and the resistance of the return air outlet is too large or too small, the return air volume will be less than or greater than the air supply volume, then the cleanliness will certainly not meet the standard.
