各位海友，请问附图的自吸泵的3个开孔嘴子的作用是什么啊？关于“Nozzle-3”，厂家资料的描述是“It is recommended to install a pipe connecting the casing NOZZLE-3 to the seal chamber or gland.
The purpose of this line is to keep the seal faces wet during the priming cycle.”
厂家给答复了，原文如下“Nozzle 1 should be filled with water before pump start.
Only water is injected first and then plugged.
The nozzle 2 is for casing drain. When the pump is repaired, it serves to empty the water in the casing.
Nozzle 3 is a mechanical auxiliary plan. You can plug it.”
