• 使用本產品之前必須認真閱讀自平衡多級離心泵選型手冊、使用說明書及相關配套產品的使用說明書。在安裝、使用和維修過程中，必須遵循本產品及其相關設備的安全操作規程。

Before using this product, you must carefully read the instruction manual of this product and the instruction manual of related supporting products. In the process of installation, use and maintenance, the safe operation rules of this product and related equipment must be followed.

• 自平衡多級離心泵不得長時間在小流量或零流量下運轉。否則會引起泵機組振動甚至抽送液體汽化，造成人身傷害和設備的損壞。

The pump must not run at low or zero flow for a long time. Otherwise it will cause the pump unit to vibrate or even the vaporization of the pumped liquid, causing personal injury and equipment damage.

• 自平衡多級離心泵為旋轉設備，在安裝、維修泵機組前必須切斷電源，否則會造成人身傷害。

The pump is a rotating device, and the power supply must be cut off before installing or maintaining the pump unit, otherwise it may cause personal injury.

• 自平衡多級離心泵在使用前必須檢查電纜線有無破損，折斷以及接地是否良好，泵機組運行時，嚴禁手進入或拆下防護罩，否則會造成人身傷害。

Before use, the pump must be inspected for damage, breakage, and good grounding. When the pump unit is running, it is strictly prohibited to enter or remove the protective cover by hand, otherwise it will cause personal injury.

• 自平衡多級離心泵在使用前，請先脫開泵與電機的連接，接通電源，“點啟動開關按鈕”確定旋轉方向正確無誤后，方可使用。

Before using the pump, please disconnect the connection between the pump and the motor, connect the power supply, and use the "point start switch button" to see?the correct direction of rotation before using it.

• 為防止泵運轉后，因泵軸與電機軸相抵出現斷軸甚至燒電機等事故，因而在調整泵、電機兩個聯軸器的間隙前，必須先將泵軸向泵聯軸器方向最大限度的外拉，然后再按說明書要求進行間隙調整。

In order to prevent accidents such as broken shafts or even burned motors due to the pump shaft and the motor shaft after the pump runs. Before adjusting the gap between the pump and motor couplings, the direction of the pump shaft to the pump coupling must be maximized pull out, and then adjust the gap according to the instructions.

• 煤礦井下使用時采配用YB3或YBK系列電機，其中采掘工作面使用應配YBK系列電機。

YB3 or YBK series motors are used for mine underground use, and YBK series motors should be used for mining face.

• 用戶與本企業均不得隨意變更安標配套件及零（元）部件配置。

Neither the user nor the enterprise shall arbitrarily change the configuration of safety standard supporting parts and components.

• 本產品屬于自平衡多級離心泵，每次開機前，必須將進水管道和泵腔內部的空氣排盡。

This product is a centrifugal pump. Before starting the machine, the air in the inlet pipe and the pump must be exhausted.
