电磁阀在工作中的可靠性与经济性 作者:aodiq71457

    工作寿命,此项不列入出厂试验项目,属于型式试验项目。为确保质量应选正规厂家的名牌产品。
  工作制式:分长期工作制,反复短时工作制和短时工作制三种。本公司常规产品均为长期工作制,即线圈允许长期通电工作。对于长时间阀门开通只有短时关闭的情况,则宜选用常开电磁阀。用在短时工作制而批量又很大时,可作特殊订货以降低功耗。
  工作频率:动作频率要求高时,结构应优选直动式电磁阀,电源听优选交流。
动作可靠性:严格地来说此项试验尚未正式列入我国电磁阀专业标准,为确保质量应选正规厂家的名牌产品。有些场合动作次数并不多,但对可靠性要求却很高,如消防、紧急保护等,切不可掉以轻心。特别重要的,还应采取两只连用双保险。
  经济性:不经济就是对资金,精力乃至生命的浪费
  它选用的尺度之一,但必须是在安全、适用、可靠的基础上的 经济。
  经济性不单是产品的售价,更要优先考虑其功能和质量以及安装维修及其它附件所需用费用。
  更重要的是,一只电磁阀在整个自控系统中在整个自控系统中乃至生产线中所占成本微乎其微,如果贪图小便宜而错选早造成损害群是巨大的。
  总之,经济性不单指产品价格,而是产品的性能价格比综合费用价格比。

Working life, this pilot project is not included in the factory, belonging to the type of pilot projects. In order to ensure the quality of the formal election of the brand manufacturers.
Working standard: sub-system of long-term, repeated short-term and short-term work of three working. Conventional products of this company are long-term work system, that is, the work coil to allow long-term electricity. For a long time to close the valve to open only a short-term situation, it should be always selected solenoid valve. Used in short-term work system and a large bulk, they can make a special order to reduce power consumption.
Operating frequency: high frequency movements, the structure should be preferred direct acting solenoid valve, preferred to listen to the exchange of power.
The reliability of action: strictly speaking, has not yet formally included in the pilot solenoid valve of our professional standards, in order to ensure the quality of the formal election of the brand manufacturers. Number of occasions, some not much action, but has very high reliability requirements, such as fire protection, emergency protection, must not be taken lightly. Of particular importance, should be taken once a double insurance 2.
Economy: the economy is not financial, energy and even a waste of life
Selected one of its scale, but must be in terms of safety, applicable on the basis of reliable economic.
Economy is not only the prices of products, but also to give priority to their functions and quality as well as installation and maintenance costs required for other accessories.
More importantly, a solenoid valve-controlled system in the whole control system in the entire production line as well as cost-share little, if just for the sake of cheap and small damage caused by the wrong group of early elections is enormous.
In short, the economy not just the price, but the cost of products, a comprehensive cost-effective prices.
