前不久,螺杆风机厂家清越节能的一家客户在安装调试螺杆鼓风机的过程中,发现同样功率的螺杆鼓风机,清越节能的设备机头比另一品牌的却要大上很多,因此就引出了标题中的疑问,这是为何呢?
Not long ago, during the installation and commissioning of screw blowers, a customer of Qingyue energy saving, a screw blower manufacturer, found that the head of Qingyue energy saving equipment with the same power is much larger than that of another brand, so it leads to the question in the title. Why?
螺杆风机厂家简单来解释一下。我们知道螺杆鼓风机等容积式鼓风机种类较多,不管具体的哪种类型,它们都是通过工作腔容积的周期性变化而实现空气输送的。在设备选择中,风量是其中基本的参数之一。那不同的机型,一定压力下不同风量的大小是如何实现的呢?
Screw fan manufacturers to explain briefly. We know that there are many types of positive displacement blowers such as screw blowers. No matter which type is specific, they realize air transmission through the periodic change of working chamber volume. Air volume is one of the basic parameters in equipment selection. How do different models achieve different air volume under certain pressure?

以螺杆风机厂家的螺杆鼓风机产品为例,风量基础的影响因素就是转子与转子以及腔体围合形成工作腔体容积与转速。这个工作腔体容积决定了鼓风机转子一个周期传输的气体量有多少。转速就更容易理解了,决定了单位时间内转子能完成多少个周期性变化。因此不考虑泄漏等影响因素,工作腔容积增加以及转速的提高都能有用提高设备风量。
Taking the screw blower products of screw fan manufacturers as an example, the influencing factors of air volume basis are the volume and speed of working cavity formed by the enclosure of rotor, rotor and cavity. The volume of the working chamber determines the amount of gas transmitted by the blower rotor in a cycle. The speed is easier to understand, which determines how many periodic changes the rotor can complete per unit time. Therefore, without considering the influence factors such as leakage, the increase of working chamber volume and the increase of rotating speed can effectively improve the air volume of the equipment.
实际应用中,螺杆鼓风机工作腔的容积一方面与型线有关,另一方面与转子与腔体的几何大小有关。型线以及转速一定的前提下,要提高风量就需要增加转子与腔体的体积,这其中就涉及设备体积与各方面成本的增加。
In practical application, the volume of working cavity of screw blower is related to the profile on the one hand and the geometric size of rotor and cavity on the other hand. On the premise of a certain profile and speed, to increase the air volume, it is necessary to increase the volume of rotor and cavity, which involves the increase of equipment volume and cost in all aspects.
而通过转速来增加风量更为便捷,但涉及到轴承的承受能力、密封等问题。转速越高轴承磨损越严重、密封更容易泄漏,需要妥善应对。另外就是通过高速转动来加大风量还会使鼓风机出口的空气流速加大,带来额外的噪音问题以及压损,以及高转速大离心力带来动平衡、磨损等问题,维护需要更为细致。
It is more convenient to increase the air volume by rotating speed, but it involves the bearing capacity, sealing and other problems of the bearing. The higher the speed, the more serious the bearing wear and the easier the seal leakage, so it needs to be handled properly. In addition, increasing the air volume through high-speed rotation will also increase the air flow rate at the outlet of the blower, resulting in additional noise problems and pressure loss, as well as dynamic balance, wear and other problems caused by high-speed and large centrifugal force. Maintenance needs to be more detailed.
