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?
