• 使用本產(chǎn)品之前必須認(rèn)真閱讀自平衡多級(jí)離心泵選型手冊(cè)、使用說明書及相關(guān)配套產(chǎn)品的使用說明書。在安裝、使用和維修過程中，必須遵循本產(chǎn)品及其相關(guān)設(shè)備的安全操作規(guī)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(jí)離心泵不得長(zhǎng)時(shí)間在小流量或零流量下運(yùn)轉(zhuǎn)。否則會(huì)引起泵機(jī)組振動(dòng)甚至抽送液體汽化，造成人身傷害和設(shè)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(jí)離心泵為旋轉(zhuǎn)設(shè)備，在安裝、維修泵機(jī)組前必須切斷電源，否則會(huì)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(jí)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(jī)組運(yùn)行時(shí)，嚴(yán)禁手進(jìn)入或拆下防護(hù)罩，否則會(huì)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(jí)離心泵在使用前，請(qǐng)先脫開泵與電機(jī)的連接，接通電源，“點(diǎn)啟動(dòng)開關(guān)按鈕”確定旋轉(zhuǎn)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(yùn)轉(zhuǎn)后，因泵軸與電機(jī)軸相抵出現(xiàn)斷軸甚至燒電機(jī)等事故，因而在調(diào)整泵、電機(jī)兩個(gè)聯(lián)軸器的間隙前，必須先將泵軸向泵聯(lián)軸器方向最大限度的外拉，然后再按說明書要求進(jìn)行間隙調(diào)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(shí)采配用YB3或YBK系列電機(jī)，其中采掘工作面使用應(yīng)配YBK系列電機(jī)。

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(yè)均不得隨意變更安標(biāo)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(chǎn)品屬于自平衡多級(jí)離心泵，每次開機(jī)前，必須將進(jìn)水管道和泵腔內(nèi)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.
