    下面就简单的介绍一下制砂生产线工艺中的三种制砂工艺。砂生产线之湿法生产;湿法制砂生产线是指三级破碎段全部采用湿法制砂生产线工艺。其特点是:可以有效的保证人工骨料成品质量,对石粉含量和含泥量可控制,降低了生产过程中的粉尘量,但系统用水量大,运行成本高,部分细砂,石粉流失,回收率较低,废水处理量大而且效果不太理想。另外,若进入立轴冲击式破碎机的骨料含水率超标,容易导致破碎腔结块堵塞,降低设备成砂率,甚至发生转子抱死的机械事故。干法制砂生产线干法制砂生产线是指几个破碎段全部采用干式生产工艺。其特点是:无供水装置。生产工艺简化,可节约系统建造投资和运行成本,但对岩石中的泥土含量难以控制,而且系统粉尘污染严重。干法制砂生产线半干法制砂生产线结合了湿法制砂生产线和干法制砂生产线的优点,即粗碎采用湿法生产,可有效去除原料中的泥土,降低粉尘排放;中细碎和中碎(仅有两个破碎段)采用干法生产,棒磨机制砂采用湿法生产,通过洗砂与脱水工艺调节成品砂的细度模数、石粉含量及含水率。
    调节阀选型的原则根据工艺条件,选择合适的结构形式和材料。根据工艺对象的特点,选择调节阀的流量特性。根据工艺操作参数,选择合适的调节阀口径尺寸。根据工艺过程的要求,选择所需要的辅助装置。合理选择执行机构。执行机构的响应速度应能满足工艺对控制行程时间的要求:所选用的调节阀执行机构应能满面足阀门行程和工艺对泄露量等级的要求。在某些场合,如选用压力调节阀(包括放空阀),应考虑实际可能的压差进行适当的放大,即要求执行机构能提供较大的作用力。
    一般水泵的铭牌上都提到允许吸上真空高度或必需汽蚀余量NPSHr,就是根据水泵在额定转速和流量下而又不产生汽蚀为原则,由制造厂试验所确定的大吸水高度,为了不发生汽蚀而限制了水泵叶轮进口处的压力不能低于某一数值。也就是说,水泵叶轮进口处的真空度不能高于某一数值。通常又把水泵叶轮进口处允许的低压力,也叫水泵的允许吸上真空度,它与允许吸上真空高度是一回事。汽蚀的防止措施屏蔽泵的实际安装高度,必须低于或等于水泵的实际吸水高度。
    FFU的外观目前,全世界所有厂家生产的FFU,从外观上可这样划分:从形状上分两种,一种是长方体(如图1所示),一种上部为坡形(如图2所示)。图2所示的FFU的上部做成坡形,起到了一种导流的作用,有利于气流的流动和均匀分布。图1所示的FFU则一般依靠另外的途径来均衡气流。从结构上分两种,一种为整体(如图3所示),一种为分体(如图4所示)。分体形状的FFU有如下优势:使过滤器的更换变得方减小了安装过程中的劳动强度。
