With regard to the wide application of fire exhaust fans, not to mention, I believe everyone is familiar with it, but there may be some vibration problems in the application process. How should we deal with them effectively at this time? Next, I will elaborate on them in detail.

　　，縮短啟動次數 我們可以利用有效的影響系數，縮短動平衡啟動次數，提高維修效率。

　　First, to shorten the start-up times, we can use the effective influence coefficient to shorten the start-up times of dynamic balance and improve the maintenance efficiency.

　　第二，保證轉子在工作時盡可能達到平衡，據相關實驗表明，如果轉子在工作時失衡水平在指標一下，不僅減少了維修時間和經費，還能延長設備的使用壽命。

　　Secondly, to ensure that the rotor works as balanced as possible, according to the relevant experiments, if the unbalance level of the rotor is under the index, not only reduces the maintenance time and funds, but also prolongs the service life of the equipment.

　　第三，控制溫度的溫差范圍 由于長時間的運行會對風機內的軸造成損傷，特別是在冬天，溫度控制的不好，這種情況會經常出現。因而，我們應該要把溫度控制在一定的范圍之內。

　　Thirdly, the range of temperature difference in the control of temperature will cause damage to the shaft in the fan due to long-term operation, especially in winter, the temperature control is not good, this situation will often occur. Therefore, we should control the temperature within a certain range.

　　風機盤管訂購時要根據具體情況來

　　Fan coil units should be ordered according to specific conditions

　　隨著我國經濟飛速發展，國內興建了許多、辦公樓、酒店等公共設施，這些建筑中大多裝有空調設備。當前，我國空調末端行業呈現出高速發展態勢，從生產到銷售的每一個環節都日漸趨于成熟，市場潛力巨大。

　　With the rapid development of China's economy, many shopping malls, office buildings, hotels and other public facilities have been built in China. Most of these buildings are equipped with central air-conditioning equipment. At present, China's central air-conditioning terminal industry shows a high-speed development trend. Every link from production to sales is becoming more and more mature, and the market potential is huge.

　　家電行業分析師指出，作為比較成熟的產品市場，消防排煙風機市場因產品技術差異小，同質化情況比較明顯；加上用戶在采購消防排煙風機產品時對要求不高，造成末端廠家進入市場的門檻較低，眾多企業的競爭較為混亂。

　　Analysts in household appliances industry pointed out that, as a mature product market, the market of fire exhaust fans has obvious homogeneity because of the small technological differences of products; in addition, users do not require high brand when purchasing fire exhaust fans, resulting in lower barriers for end-users to enter the market and more mixed competition among many enterprises. Chaos.

　　風機盤管閥體黃銅鍛造,不銹鋼桿及彈簧,體積小,耐腐蝕.閥芯結構優化，在不減少Kv值的情況下，允許壓差大。風機盤管驅動器與閥體分離，可快速拆裝。驅動器有可供系統調試和維修使作用的手動操作桿。這是新款風機盤管優于其他類風機盤管的地方，當然除此之外這款風機盤管還有其他更多優勢，針對不同用途我們不同機型，所以在您下單時請敘述清楚使用風機盤管的主要用途及場合。

　　Brass forging of fan coil valve body, stainless steel rod and spring, small size, corrosion resistance. Core structure optimization, without reducing the Kv value, the allowable pressure difference is large. The fan coil driver is separated from the valve body and can be quickly disassembled and assembled. The driver has a manual lever for system debugging and maintenance. This is where the new fan-coil unit is superior to other types of fan-coil units. Of course, this fan-coil unit has other advantages. We recommend different models for different purposes. So when you place your order, please describe clearly the main uses and occasions of using fan-coil unit.
