隔爆直流湿式阀用电磁铁使用说明书

电磁阀的使用说明选型要领：电磁阀选型首先应该依次遵循安全性，可靠性，适用性，经济性四大原则，其次是根据六个方面的现场工况(即管道参数、流体参数、压力参数、电气参数、动作方式、特殊要求进行选择)。

选型依据：一、根据管道参数选择电磁阀的：通径规格(即DN)、接口方式1、按照现场管道内径尺寸或流量要求来确定通径(DN)尺寸。

2、接口方式，一般>DN50要选择法兰接口，≤DN50则可根据用户需要自由选择。

二、根据流体参数选择电磁阀的：材质、温度组1、腐蚀性流体：宜选用耐腐蚀电磁阀和全不锈钢；食用超净流体：宜选用食品级不锈钢材质电磁阀。

2、高温流体：要选择采用耐高温的电工材料和密封材料制造的电磁阀，而且要选择活塞式结构类型的。

3、流体状态：大至有气态，液态或混合状态，特别是口径大于DN25订货时一定要区分开来。

4、流体粘度：通常在50cSt以下可任意选择，若超过此值，则要选用高粘度电磁阀。

三、根据压力参数选择电磁阀的：原理和结构品种1、公称压力：这个参数与其它通用阀门的含义是一样的，是根据管道公称压力来定。

2、工作压力：如果工作压力低则必须选用直动或分步直动式原理；最低工作压差在0.04Mpa以上时直动式、分步直动式、先导式均可选用。

四、电气选择：电压规格应尽量优先选用AC220V、DC24较为方便。

五、根据持续工作时间长短来选择：常闭、常开、或可持续通电1、当电磁阀需要长时间开启，并且持续的时间多余关闭的时间应选用常开型。

2、要是开启的时间短或开和关的时间不多时，则选常闭型。

3、但是有些用于安全保护的工况，如炉、窑火焰监测，则不能选常开的，应选可长期通电型。

六、根据环境要求选择辅助功能：防爆、止回、手动、防水雾、水淋、潜水1、爆炸性环境：必须选用相应防爆等级的电磁阀2、当管内流体有倒流现象时，可选择带止回功能电磁阀。

3、当需要对电磁阀进行现场人工操作时，可选择带手动功能电磁阀。

4、露天安装或粉尘多场合应选用防水，防尘品种(防护等级在IP54以上)。

KG:1. General Customer ResponsibilitySome goods within the product range of Würth Elektronik eiSos GmbH & Co. KG contain statements regarding general suitability for certain application areas. These statements about suitability are based on our knowledge and experience of typical requirements concerning the areas, serve as general guidance and cannot be estimated as binding statements about the suitability for a customer application. The responsibility for the applicability and use in a particular customer design is always solely within the authority of the customer. Due to this fact it is up to the customer to evaluate, where appropriate to investigate and decide whether the device with the specific product characteristics described in the product specification is valid and suitable for the respective customer application or not.2. Customer Responsibility related to Specific, in particular Safety-Relevant ApplicationsIt has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime cannot be completely eliminated in the current state of the art, even if the products are operated within the range of the specifications.In certain customer applications requiring a very high level of safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health it must be ensured by most advanced technological aid of suitable design of the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic component. Therefore, customer is cautioned to verify that data sheets are current before placing orders. The current data sheets can be downloaded at .3. Best Care and AttentionAny product-specific notes, cautions and warnings must be strictly observed. Any disregard will result in the loss of warranty.4. Customer Support for Product SpecificationsSome products within the product range may contain substances which are subject to restrictions in certain jurisdictions in order to serve specific technical requirements. Necessary information is available on request. In this case the field sales engineer or the internal sales person in charge should be contacted who will be happy to support in this matter.5. Product R&DDue to constant product improvement product specifications may change from time to time. As a standard reporting procedure of the Product Change Notification (PCN) according to the JEDEC-Standard inform about minor and major changes. In case of further queries regarding the PCN, the field sales engineer or the internal sales person in charge should be contacted. The basic responsibility of the customer as per Section 1 and 2 remains unaffected.6. Product Life CycleDue to technical progress and economical evaluation we also reserve the right to discontinue production and delivery of products. As a standard reporting procedure of the Product Termination Notification (PTN) according to the JEDEC-Standard we will inform at an early stage about inevitable product discontinuance. According to this we cannot guarantee that all products within our product range will always be available. Therefore it needs to be verified with the field sales engineer or the internal sales person in charge about the current product availability expectancy before or when the product for application design-in disposal is considered. The approach named above does not apply in the case of individual agreements deviating from the foregoing for customer-specific products.7. Property RightsAll the rights for contractual products produced by Würth Elektronik eiSos GmbH & Co. KG on the basis of ideas, development contracts as well as models or templates that are subject to copyright, patent or commercial protection supplied to the customer will remain with Würth Elektronik eiSos GmbH & Co.
