進(jìn)口潛水深井泵概述
1、進(jìn)口潛水深井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。深井泵葉輪在電機(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、潛水深井泵的電機(jī)為密閉充水濕式結(jié)構(gòu)。電機(jī)定子繞組采用耐水的聚乙烯絕緣，尼龍護(hù)套多層結(jié)構(gòu)的電磁線。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、潛水深井泵的管路部分：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。夾板是在深井泵的安裝過程中吊裝和固定輸出管路。

Imported submersible deep well pump
British imports submersible deep well pump Submersible deep well pump
Introduction of imported submersible deep well pump
1, imported submersible deep well pump for centrifugal or mixed flow type; water lubricated bearings; and the use of motor coupling coupling rigid coupling. The impeller of the deep well pump is driven by a motor to rotate to generate centrifugal force, so that the energy of the liquid can be increased through the diversion of the pump shell. The upper end of the water pump is provided with a non-return valve body, which prevents the water from flowing back in the water pipe to damage the working part 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: low lift submersible pump without check valve)
2, submersible deep well pump motor for closed water filled wet structure. The stator winding of the motor is made of water resistant polyethylene insulation, and the electromagnetic wire of nylon sheath multilayer structure. Guide bearings and thrust bearings are lubricated with water. The motor is filled with water to cool the motor and the bearing. 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 shaft of the motor is provided with a sand prevention mechanism for preventing the mud and sand from entering into the inner part of the machine body.
3, submersible deep well pump part of the pipeline: to connect the pump to lift it in the well, the water will be sent to the ground. Mainly composed of short water pipes, water pipes, elbows, plywood and other components. The short output pipe is the connecting part of the water pipe and the electric pump. The elbow is installed at the wellhead to change the direction of flow. In the installation process of the deep well pump, the clamping plate is used for hoisting and fixing the output pipeline.
