QW系列潜水排污泵

QW系列潜水排污泵主要用于市政工程、工农业、医院、建筑、宾馆、饭店等行业。用于输送带固体及各种长纤维的废水，城市生活污水和雨水，还包括原水的输送、水产养殖、灌溉（配以特种材质，可用于有一定腐蚀性的介质场合）。产品设计型谱化，效率高，防缠绕，无堵塞，自动耦合，高可靠，自动控制和自动保护，并设置了各种状态显示保护装置。泵的性能覆盖面大：泵与电机共轴，结构紧凑，便于维修；可按用户要求提供特殊电压泵型，进行水位自动控制，并配有自动保护装置及控制柜。

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.

泵壳和叶轮之间装有易于更换的耐磨环。泵壳为单蜗壳型，分布于叶轮周围收集液体。过流表面光滑，通道断面大，效率高，无堵塞。叶片式或流道式大通道叶轮，具有较强的抗缠绕和无堵塞性能，经过动平衡试验，运行平稳。油润滑并冷却密封，在电机与所输送的介质之间起到隔离作用。内留的体积可减缓油室内压力的升高。两套独立的机械密封（视泵的结构而不同），使电机与泵密封隔离；上下串联安装，提供双重保险，提高了可靠性。采用滚动轴承，能承受所有的轴向和径向载荷，并完全与泵所输送的介质分开。泵与电机同轴，结构紧凑，轴伸尽量缩短，从设计上减小挠度，运动时振动小，密封和轴承寿命更长。高性能鼠笼式感应电机，特别为潜水泵设计制造，符合GB755标准。绝缘等级为F级，最高工作温度可达135℃。电机外壳采用内循环冷却（22KW以上泵适用）。潜水排污泵装有多道监测保护装置，可把引线引至电控箱。保护装置有：过载、缺相、泄漏、超温、湿度、浸水保护等（视泵的结构不同而有所差别）。

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).
