前不久,螺桿風(fēng)機(jī)廠家清越的一家客戶在安裝調(diào)試螺桿鼓風(fēng)機(jī)的過程中,發(fā)現(xiàn)同樣功率的螺桿鼓風(fēng)機(jī),清越的設(shè)備機(jī)頭比另一的卻要大上很多,因此就引出了標(biāo)題中的疑問,這是為何呢?

Not long ago, a customer of Qingyue, a screw blower manufacturer, found that the head of Qingyue's screw blower with the same power was much larger than that of another brand in the process of installing and debugging the screw blower. Therefore, the question in the title was raised. Why?

螺桿風(fēng)機(jī)廠家簡單來解釋一下。我們知道螺桿鼓風(fēng)機(jī)等容積式鼓風(fēng)機(jī)種類較多,不管具體的哪種類型,它們都是通過工作腔容積的周期性變化而實(shí)現(xiàn)空氣輸送的。在設(shè)備選擇中,風(fēng)量是其中基本的參數(shù)之一。那不同的機(jī)型,一定壓力下不同風(fēng)量的大小是如何實(shí)現(xiàn)的呢?

Screw fan manufacturers to explain briefly. We know that there are many types of positive displacement blowers, such as screw blower. No matter which type is specific, they all realize air delivery through the periodic change of working chamber volume. In equipment selection, air volume is one of the basic parameters. How to achieve different air volume under certain pressure for different models?以螺桿風(fēng)機(jī)廠家的螺桿鼓風(fēng)機(jī)產(chǎn)品為例,風(fēng)量基礎(chǔ)的影響因素就是轉(zhuǎn)子與轉(zhuǎn)子以及腔體圍合形成工作腔體容積與轉(zhuǎn)速。這個(gè)工作腔體容積決定了鼓風(fēng)機(jī)轉(zhuǎn)子一個(gè)周期傳輸?shù)臍怏w量有多少。轉(zhuǎn)速就更容易理解了,決定了單位時(shí)間內(nèi)轉(zhuǎn)子能完成多少個(gè)周期性變化。因此不考慮泄漏等影響因素,工作腔容積增加以及轉(zhuǎn)速的提高都能有用提高設(shè)備風(fēng)量。Taking the screw blower products of screw blower manufacturers as an example, the influencing factors of air volume basis are the volume and speed of working cavity formed by rotor and rotor and cavity enclosure. The volume of the working cavity determines how much gas the blower rotor transmits in one cycle. The speed is easier to understand, which determines how many periodic changes the rotor can complete in unit time. Therefore, regardless of the influence factors such as leakage, the increase of working chamber volume and rotating speed can effectively improve the air volume of the equipment.

實(shí)際應(yīng)用中,螺桿鼓風(fēng)機(jī)工作腔的容積一方面與型線有關(guān),另一方面與轉(zhuǎn)子與腔體的幾何大小有關(guān)。型線以及轉(zhuǎn)速一定的前提下,要提高風(fēng)量就需要增加轉(zhuǎn)子與腔體的體積,這其中就涉及設(shè)備體積與各方面成本的增加。而通過轉(zhuǎn)速來增加風(fēng)量更為便捷,但涉及到軸承的承受能力、密封等問題。轉(zhuǎn)速越高軸承磨損越嚴(yán)重、密封更容易泄漏,需要妥善應(yīng)對。

In practical application, the volume of the 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. Under the premise of a certain profile and speed, to improve the air volume, it is necessary to increase the volume of rotor and cavity, which involves the increase of equipment volume and various costs. It is more convenient to increase air volume by rotating speed, but it involves bearing capacity, sealing and other issues. The higher the rotating speed is, the more serious the bearing wear is, and the seal is more likely to leak, which needs to be dealt with properly.

另外就是通過高速轉(zhuǎn)動(dòng)來增大風(fēng)量還會(huì)使鼓風(fēng)機(jī)出口的空氣流速加大,帶來額外的噪音問題以及壓損,以及高轉(zhuǎn)速離心力帶來動(dòng)平衡、磨損等問題,維護(hù)需要更為細(xì)致。

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 centrifugal force, so the maintenance needs to be more meticulous.

在這個(gè)方面采取的就是大機(jī)頭、低轉(zhuǎn)速的路線,以保證穩(wěn)定的產(chǎn)品性能。不同的企業(yè)選擇的方向也會(huì)不同。落實(shí)到具體產(chǎn)品上,差不多的風(fēng)量,山東螺桿鼓風(fēng)機(jī)相對于一些小機(jī)頭、高轉(zhuǎn)速的產(chǎn)品,螺桿主機(jī)在體積上自然就會(huì)大出很多,但轉(zhuǎn)速也會(huì)相應(yīng)較低。

In this respect, we adopt the route of large nose and low speed to ensure stable product performance. Different enterprises will choose different directions. When it comes to specific products, with almost the same air volume, compared with some products with small head and high speed, the screw host will naturally be much larger in volume, but the speed will also be relatively low.
