英國GRIMM格林進(jìn)口井用潛水泵結(jié)構(gòu)說明： 

1、進(jìn)口井用潛水泵為離心式或混流式；采用水潤滑軸承；與電機(jī)的聯(lián)接采用聯(lián)軸器剛性聯(lián)接。泵葉輪在電機(jī)帶動(dòng)下旋轉(zhuǎn)產(chǎn)生離心力，使液體能量增加經(jīng)泵殼的導(dǎo)流作用進(jìn)行提水。在水泵上端設(shè)有逆止閥體，防止電泵停機(jī)時(shí)，因揚(yáng)水管中倒流的水損壞工作部件。閥上有泄水孔，可將管路中的水緩緩放掉，防止冬天凍裂管路。(注：低揚(yáng)程潛水泵不設(shè)逆止閥體)
2、電機(jī)為密閉充水濕式結(jié)構(gòu)。電機(jī)定子繞組采用耐水(耐熱)的聚乙烯絕緣，尼龍護(hù)套多層結(jié)構(gòu)的(耐熱)電磁線。導(dǎo)軸承及推力軸承均采用水潤滑材質(zhì)。電機(jī)內(nèi)部充滿清水，用以冷卻電機(jī)和潤滑軸承。電機(jī)底部裝有調(diào)壓膜，用以調(diào)整由電機(jī)溫升引起的機(jī)體內(nèi)清水的脹縮壓差。電機(jī)的上端軸上裝有防砂機(jī)構(gòu)，用來阻止水中泥砂進(jìn)入機(jī)體內(nèi)部。
3、管路部分：用以聯(lián)接電泵使其吊裝在機(jī)井中，將水輸送到地面上去。主要由短輸水管、輸水管、彎管、夾板等部件組成。短輸出管是輸水管路與電泵的連接過渡部件。彎管安裝在井口處，以改變水流的傳送方向。夾板是在電泵的安裝過程中吊裝和固定輸出管路。

UK GRIMM Submersible pumps for imported wells structure description:

1.The submersible pump for the well is centrifugal or mixed flow. The water lubricated bearing is adopted. The coupling of the motor and the motor is connected by a rigid coupling. The pump impeller is driven by the motor to rotate to generate centrifugal force, so that the liquid energy is increased, and the water pumping is carried out by the diversion action of the pump shell. A non-return valve body is arranged at the upper end of the water pump to prevent the working parts of the water pump from being damaged by the backflow of water in the water pipe when the electric pump is stopped. The valve is provided with a drain hole of the water in the pipeline can be slowly discharged, to prevent the winter frost crack pipe. (Note: the low lift submersible pump does not have a non-return valve body)

2.The motor is closed water filled wet structure. The motor stator winding adopts water (heat resistant) polyethylene insulated, nylon sheath multilayer structure (heat resistant) electromagnetic wire. Guide bearings and thrust bearings are made of water lubricated material. The motor is filled with clean water to cool the motor and lubricate the bearings. The motor is arranged at the bottom of the pressure adjusting membrane, to adjust the motor temperature rise caused by the expansion and contraction of the water pressure difference. The upper end of the motor is provided with a sand prevention mechanism to prevent mud and sand from entering the interior of the machine.

3.Pipeline part: used to connect the electric pump, lifting it in the well, and transport the water to the ground. Mainly by short water pipe, water pipe, elbow, plywood and other components. The short output pipe is a connecting transition component between the water delivery pipe and the electric pump. The pipe is installed at the wellhead to change the direction of the flow. The clamping plate is lifting and fixing the output pipeline during the installation of the electric pump.
