進口潛水深井泵概述
1、潛水深井泵為離心式或混流式;采用水潤滑軸承;與電機的聯接采用聯軸器剛性聯接。深井泵葉輪在電機帶動下旋轉產生離心力,使液體能量增加經泵殼的導流作用進行提水。在水泵上端設有逆止閥體,防止電泵停機時,因揚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:低揚程潛水泵不設逆止閥體)
2、潛水深井泵的電機為密閉充水濕式結構。電機定子繞組采用耐水的聚乙烯絕緣,尼龍護套多層結構的電磁線。導軸承及推力軸承均采用水潤滑材質。電機內部充滿清水,用以冷卻電機和潤滑軸承。電機底部裝有調壓膜,用以調整由電機溫升引起的機體內清水的脹縮壓差。電機的上端軸上裝有防砂機構,用來阻止水中泥砂進入機體內部。
3、潛水深井泵的管路部分:用以聯接電泵使其吊裝在機井中,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。

Stainless steel deep well pump
British imports of stainless steel submersible pump Stainless steel submersible pump
Introduction of imported submersible deep well pump
1, submersible deep well pump for centrifugal or mixed flow type; using water lubricated bearings; and the coupling of motor 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.
Conditions for the import of submersible deep well pumps

(2) the load capacity of the transformer shall not exceed 75% of its capacity.
(3) transformer is far from the well, should consider the transmission line voltage, the motor power is greater than 45KW, requirements of the transformer to the wellhead distance not exceeding 20 meters, more than 20 meters, the transmission line cable specification requirements specifications than the big two grades, and consider the line pressure drop.
2 water quality requirements:
(1) general non corrosive water.
(2) the sand content in water is not more than 0.01% (mass ratio).
(3) pH pH value in the range of 6.5-8.5.
