QW系列潛水排污泵主要用于市政工程、工農(nóng)業(yè)、醫(yī)院、建筑、賓館、飯店等行業(yè)。用于輸送帶固體及各種長纖維的廢水，城市生活污水和雨水，還包括原水的輸送、水產(chǎn)養(yǎng)殖、灌溉（配以特種材質(zhì)，可用于有一定腐蝕性的介質(zhì)場合）。產(chǎn)品設(shè)計型譜化，效率高，防纏繞，無堵塞，自動耦合，高可靠，自動控制和自動保護，并設(shè)置了各種狀態(tài)顯示保護裝置。泵的性能覆蓋面大：泵與電機共軸，結(jié)構(gòu)緊湊，便于維修；可按用戶要求提供特殊電壓泵型，進(jìn)行水位自動控制，并配有自動保護裝置及控制柜。
QW series submersible sewage pump is mainly used in municipal engineering, and industry and agriculture, hospitals, building, hotel, restaurant, etc. Used for solid and various kinds of long fiber conveyor belt of wastewater, sewage and rain, city life also include raw water transport, aquaculture, irrigation (match with special material, can be used to have certain corrosive medium occasions). The XingPu product design, high efficiency, and the winding, no congestion, automatic coupling, high reliability, automatic control and automatic protection, and set the various states show protection device. The performance of the pump has a wide coverage: pump and motor shaft, of compact structure, convenient in maintenance; According to user requirements to provide special voltage pump type, the water level automatic control, and is equipped with automatic protection device and the control cabinet.
泵殼和葉輪之間裝有易于更換的耐磨環(huán)。泵殼為單蝸殼型，分布于葉輪周圍收集液體。過流表面光滑，通道斷面大，效率高，無堵塞。葉片式或流道式大通道葉輪，具有較強的抗纏繞和無堵塞性能，經(jīng)過動平衡試驗，運行平穩(wěn)。油潤滑并冷卻密封，在電機與所輸送的介質(zhì)之間起到隔離作用。內(nèi)留的體積可減緩油室內(nèi)壓力的升高。兩套獨立的機械密封（視泵的結(jié)構(gòu)而不同），使電機與泵密封隔離；上下串聯(lián)安裝，提供雙重保險，提高了可靠性。采用滾動軸承，能承受所有的軸向和徑向載荷，并與泵所輸送的介質(zhì)分開。泵與電機同軸，結(jié)構(gòu)緊湊，軸伸盡量縮短，從設(shè)計上減小撓度，運動時振動小，密封和軸承壽命更長。高性能鼠籠式感應(yīng)電機，特別為潛水泵設(shè)計制造，符合GB755標(biāo)準(zhǔn)。絕緣等級為F級，工作溫度可達(dá)135℃。電機外殼采用內(nèi)循環(huán)冷卻（22KW以上泵適用）。潛水排污泵裝有多道監(jiān)測保護裝置，可把引線引至電控箱。保護裝置有：過載、缺相、泄漏、超溫、濕度、浸水保護等（視泵的結(jié)構(gòu)不同而有所差別）。
Pump impeller with shell and between easily replaced wear-resisting ring. Pump shell for single spiral type, distributed in collecting liquid around impeller. The flow smooth surface, the channel big cross section, high efficiency, and no jam. Vane or port type channel impeller, and has strong resistance to coil and non-clogged performance, through dynamic balance test, smooth operation. Oil lubrication and cooling seal, in which the motor and transmission media play a role. Between isolation In the volume of oil can slow down a rising pressure indoor. Separate sets of mechanical seal (depending on the structure of the pump and motor and make different), pump seal isolation; Up and down, provides double insurance series installation, improve the reliability. The rolling bearing, can bear all the axial and radial load, and completely and the conveying pump medium apart. Pump and motor coaxial, compact structure, shaft shortened from design, stretched out as far as possible reduce deflection, motion small vibration, seal and bearing life longer. High performance mouse cage type induction motor, especially for submersible pump design manufacture, accord with GB755 standards. Insulation class F, the highest working temperature level up to 135 ℃. The shell is made of motor in circulating cooling (22 KW above pump applicable). Diving sewage pump contains much way monitoring device, can protect the electrical leads to lead. Protection device: overload, phase lack, leakage, the humidity and temperature, the water immersion protection (as the pump structure and somewhat different commandingofficer).
