2．1泵為臥式懸臂、單級(jí)、單吸。軸向進(jìn)水。自吸泵采用外混合式泵體結(jié)構(gòu)。泵體由吸水彎管、蝸殼、氣水分離腔等部分組成。蝸殼下部有軸向回流孔。
The pump,with a horizontal
suspension arm,is a single-stage,one-way suction．axial entry,and self-sucking one．nle structure of the pump body IS of mixed flow type．The pump body is composed of a suction bend，a
snarl casing，an air-water separating cavity and a water
storage cbambeL At the bottom ofthe snail casing there is all axial return flow
opening．
2．2后蓋內(nèi)為密封腔，內(nèi)裝有填料密封或端面密封。泵軸和葉輪的重量，以及葉輪產(chǎn)生的徑向力，由托架內(nèi)的兩個(gè)向心軸承支承。泵和電機(jī)通過(guò)彈性聯(lián)軸器聯(lián)接并傳遞扭矩。
Inside the nerar pump cover
there is a sealed cavity,in which fiUer seal or axial seal is fitted．The weight ofthe pump
shaft and the vane whirl，together with the radial force
created by the vane whirl，is supported by the two
centripetal bearings in the bracket．To convey torque，an elastic coupling joint is installed to connect the pump and
themotor．
2．3泵體下部鑄出兩個(gè)底腳，泵與電機(jī)一起固定在底座上。皮帶輪傳動(dòng)型式用戶必須在合同上注明，否則按供底座型式供貨。
Two stands are cast to the
lower part of the pump．Both the pump and the motor ale fixed to the base．Our customers who want pumps driven by belt pulley are suggested to
specify it clearly in the contract SO as to avoid wrong shipment．The other model of pumps with a base will be delivered otherwise．
2．4泵體頂部及底部均有螺塞，分別作灌水和放水用。為了防止停車后泵內(nèi)
