当真空组件 (如阀门、水捕集器、真空吸尘器和真空泵) 相互连接时
When vacuum components such as valves, water traps, vacuum cleaners, and vacuum pumps are connected to each other, the suction pipe should be short, the pipe guide capacity should be large, and the pipe diameter should generally not be less than the pump port diameter. This is an important principle in vacuum system design. When designing a vacuum system, both installation and maintenance convenience should be considered simultaneously. Sometimes, in order to prevent vibration and reduce noise, it is allowed to install mechanical pumps in the pump room near the vacuum chamber
2. Mechanical pumps (including Roots pumps) experience vibration, and in order to prevent the vibration from affecting the entire system, hoses are usually used for vibration reduction. There are two types of hoses, metal hoses and non-metal hoses. Regardless of which type of hose is used, it should be ensured that it will not be compressed under atmospheric pressure. 3. After the vacuum system is completed, it should be easy to measure and leak. Production practice tells us that vacuum systems are prone to gas accumulation during operation, which affects production. In order to quickly find the leakage hole, segmented leakage detection should be carried out. Therefore, each part that is closed with a valve should have at least one measuring point for detecting leaks.
4,真空系统中用于鸡蛋制备的阀门和管道应确保泵送时间短,使用方便,可靠。通常,在具有机械泵作为前级泵的系统中,有一个蒸汽流量泵作为主泵 (分散泵或机油增压泵)。除了前级管道 (与机械泵电气连接的蒸汽流泵管道) 外,还应该有真空管道 (真空室管道穿过机器城市泵)。其次,在真空室和主泵之间设置一个雪高真空宽度 (他称为主泵),在前级管道上设置前级管道网络 (他称为真空保护网络),并且在预真空管道上设置了预真空管道网络 (他称为低真空酒)。主泵上的高真空等级不能在网络差下的真空电压状态下说话,而应在烟雾罩上的大气下说话。在乐力的影响下,这个城市获得了电气工会的中心母亲证书,部级管理询问照片,以及pre direct航空和公路网络办公室。老连神门在大理和乐里的影响下开了,景耀山牛泵的主网在盛产汽流豆的直信系统中进行了培训,前一级营路的假收应由永善牛泵进行,并且预直空气管道应在空房和机械原始洪水管道上配备公排风限制。当机城在矿井中停止工作时,可以立即打开柜门,打开松散的泵组件进入大气的入口,以防止机械泵油干净地返回营地道路。因此,烟门市场应与机械设备电气连接,并且不应在直风室上安装必要的气体和烟雾,以进行物料的输送和返回。从旧商店到酒店旅行时,烟门的价格应该相对较高,以防止真空室中的薄弱部件因过量的脉冲油而损坏。排气阀的大小与真空室的容积有关,应考虑排气时间不要太长,否则会影响工作
5,真空系统的设计应确保无气体稳定性,易于安装,拆卸,维护,操作方便,组件之间的互操作性。为了在运行过程中实现固定排气,要求牛泵组件可以固定,每个烟雾门可以操作,密封可以多年密封,真空流密封组件可以电气良好,备用直式空气组件的连接应使用标准尺寸进行,以确保互操作性。在真空系统的设计中,每个封闭管道的最大尺寸应是可调的。在过去,可调整的尺寸是通过软管解决的。如今,在系统的设计中,大多数软管都没有使用。通过提高真空组件的精度并将它们连接起来,应调整最大尺寸。原则上,在法兰上使用密封橡胶圈,以解决安装误差,提高系统的强度和刚度,并减少系统上使用的支撑,使系统更加美观。
