水環真空泵一直非常關注粗糙真空的獲得,例如真空過濾,真空水轉移,真空蒸發等。它已廣泛用于工業生產的許多過程中。 為了節約能源,有必要盡可能地節約能源。我們如何使用水環真空泵來節能? 1. 水環真空泵對角安裝,以減小彎頭或蝸殼,使水口面向水池。 2.縮短水環真空泵管道,拆除1米長的鋼管,并在10小時內節省0.21千克柴油。 3.擴大水環真空泵的出口管直徑。例如,將15米長的4米長水管替換為15厘米長的管道,并節省10公斤柴油10小時。 4.如果可以保持進水清潔,則可以卸下水環真空泵過濾器。 5.更換水環真空泵口環,調整軸向間隙,以防止葉輪口環和軸向間隙不合適。使用時,請根據水環真空泵的出廠說明進行調整。注意要求,避免不當操作損壞設備 6.應及時清洗水環真空泵設備管路堵塞:異物殘留在進水管,葉輪或導流殼的流路中,會降低水環真空泵的出水量 7.防止吸入水環真空泵。當進入空
