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, 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 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?
山東螺桿鼓風(fēng)機(jī)
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 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.
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。
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。另外就是通過高速轉(zhuǎn)動(dòng)來加大風(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)速大離心力帶來動(dòng)平衡、磨損等問題,維護(hù)需要更為細(xì)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.
