正压稀相输送：它是利用低于3kg/cm2 的气体压力，采用正压(吹送式)，以较高的速度来推动或拉动物料使其通过整条输送线，因此该输送方式被称之为低压高速系统，它具有较高的气体-物料比。正压稀相输送的介质一般采用空气或氮气，动力提供一般由罗茨鼓风机提供，氮气输送时则有制氮机进行提供。罗茨鼓风机的稀相输送时，物料在管道中呈悬浮状态，输送距离可以达百米，在该系统的开始端约有600m/min 的加速度，在末端可达2000m/min 的高速，因此气流速度较高。输送管线初端压力一般低于0.05Mpa，而末端则与大气压基本接近。正压稀相输送系统：适用于单点对单点，单点对多点的输送。正压稀相输送系统特点：由于系统处于正压，所以密封性要求很高，若有一丝泄漏就会造成供料端或者整个系统的粉尘外溢;系统物料采用吹送式，所以末端物料容易从卸料口排出，因此末端构造较简单;但系统的输送温度较高，对于一些特殊易热敏物料必须做降温处理;罗茨风机作为动力源，压力不能达到很高，故输送距离和产量不能同时取zui大值。负压稀相输送系统采用负压罗茨泵动力源，管道输送压力呈低真空状态，管道风速约10—35m/秒，物料在管道里呈雾状。负压输送起点压力等于或接近大气压，终点压力在-10至~50Kpa之间，管道真空度沿输送管道逐渐增高。负压稀相输送系统也称为真空稀相输送系统。星型卸料器特点：星型卸料器是气力输送系统中的关键设备。也是除尘和加料系统的常用设备。根据特性、用途和使用条件的不同，星型卸料器有多种结构型式，星型卸料器的选型要根据被输送物料的特性如堆积密度、物料温度、吸潮性、含水量、粒径、流动性、硬度、腐蚀性等来决定的。【电话/微信咨询：陈经理18068546632】常州同得利机械厂主要制造适用于粉体、颗粒、粘性的，含坚硬杂质的以及高温高压或高真空情况下使用的特殊结构的星型卸料器。以及超小尺寸的卸料器，都是非常规结构特殊非标定制。我公司专 业生产(B)GFY、YJD系列关风机(关风器)、星型卸料器、DS系列电动锁气器、DN型旋转阀，快开阀、清洁阀、风送式旋转阀等产品。广泛应用于锂电池、粮食、饲料、石油化工、制药、淀粉、油脂、化工干燥、塑料、除尘、冶金、环保、电子、煤炭、建筑、电力机械等行业设备上。用于固体粒料、粉料、超微粉体在气力输送及管网正负压状态下的卸料。【电话/微信咨询：陈经理18068546632】     《扫二维码-添加 陈经理 微信-咨询正负压输送卸料阀》Positive pressure dilute phase conveying: It uses gas pressure below 3kg/cm2 and adopts positive pressure (blowing type) to push or pull materials through the entire conveying line at a high speed. Therefore, this conveying method is called low-pressure high-speed system, which has a high gas material ratio.The medium for positive pressure dilute phase transportation is generally air or nitrogen, and the power supply is usually provided by a Roots blower. When transporting nitrogen, a nitrogen generator is used. When the Roots blower is used for dilute phase conveying, the material is suspended in the pipeline, and the conveying distance can reach up to 100 meters. At the beginning of the system, there is an acceleration of about 600m/min, and at the end, it can reach a high speed of 2000m/min. Therefore, the airflow velocity is relatively high. The initial pressure of the conveying pipeline is generally lower than 0.05Mpa, while the end pressure is basically close to atmospheric pressure.Positive pressure dilute phase conveying system: suitable for single point to single point and single point to multi-point conveying.Characteristics of positive pressure dilute phase conveying system:Due to the positive pressure of the system, high sealing requirements are required. Any slight leakage can cause dust to overflow from the feeding end or the entire system; The system material adopts a blowing type, so the end material is easily discharged from the discharge port, so the end structure is relatively simple; But the conveying temperature of the system is relatively high, and cooling treatment must be carried out for some special heat sensitive materials; As a power source, the Roots blower cannot achieve very high pressure, so the conveying distance and output cannot be maximized simultaneously.The negative pressure dilute phase conveying system adopts a negative pressure Roots pump power source, and the pipeline conveying pressure is in a low vacuum state. The pipeline wind speed is about 10-35m/s, and the material is in a mist state in the pipeline. The starting pressure of negative pressure conveying is equal to or close to atmospheric pressure, and the ending pressure is between -10 and~50Kpa. The vacuum degree of the pipeline gradually increases along the conveying pipeline. The negative pressure dilute phase conveying system is also known as the vacuum dilute phase conveying system.
