产品概述Product description

WQ(QW)系列潜水式无堵塞排污泵在引进联邦德国ABS制泵公司先进技术的基础上，在经我公司科研人员的共同努力下，同时广泛征求国内水泵专家的意见，并经过多次改良而研制成功的，经测试各项性能指标均达到国外同类产品的先进水平。
流量：8-2000m3/h,扬程：7-60m,根据使用介质，安装方式不同，设计制造成同性能参数的YW、LW、GW系列产品。
WQ (QW) series submerged non-clogging sewage pump is a gathering of the advanced technology from Germany ABS, the joint efforts of our technological personnel, and the extensive suggestions from pump experts at home. After times of improvement, it has been tested to keep in parallel with the advanced level of the similar products abroad in all performance criteria. 
Flow 8-2000m3/h, head 7-60m, and can be designed and manufactured to YW, LW and GW series of the same parameters according to the difference in service medium and installation mode. 

产品特点Product characteristics

1、采用独特的单片或双片叶轮结构，大大提高了污物通过能力，能有效的通过泵口径的5倍纤维物质与直径为泵口径约50%的固体颗粒。
2、机械密封采用新型硬质耐腐的钛化钨材料，可使泵安全连续运行8000小时以上。
3、整体结构紧凑、体积小、噪声小、节能效果显著，检修方便，无需建泵房，潜入水中即可工作，大大减少工程造价。
4、该泵密封油室内设置有高精度抗干扰漏水检测传感器，定子绕组内预埋了热敏元件，对水泵电机自动保护。
5、可根据用户需要配备全自动控制柜，对泵的漏水、漏电、过载及超温等进行自动保护，提高了产品的安全性与可靠性。
6、浮球开关可以根据所需液位变化，自动控制泵的起动与停止，不需专人看管，使用极为方便。
7、WQ系列可根据用户需要配备双导轨自动耦合安装系统，它给安装、维修带来更大方便，人可不必为此而进入污水坑。
8、能够在全扬程内使用，而保证电机不会过载。
9、有两种不同的安装方式，固定式自动耦合安装系统、移动式自由安装系统。
1. Distinctive single vane or double vane impeller to greatly improve the through capacity of sewage, which can handle fibre material 5 times of pump diameter and solid particles 50% of pump diameter. 
?. Mechanical seal uses latest anticorrosive hard tungsten titanium material to enable safe service above 8,000 hours continuously.
?. Compact structure, small volume, low noise, outstanding energy conservation, easy to check and maintain, no need of pump room, gotten into working while being submerged into water, and great reduction of construction cost.
?. There is a high precision anti-interference leakage detection sensor fitted in the enclosed oil chamber, and a thermosensitive element fitted in stator winding to carry out automatic protection of pump motor.
?. If requested by users, it can be equipped with full automatic control cabinet to carry out automatic protection to the water leakage, creepage, overload and overtemperature of pump, which has greatly enhanced the security and dependability of the product.
?. Float switch can automatically control the start and stop of pump according to the variation of required liquid level, with no need of a special person to care about, making operation quite easy.
?. If needed, WQ series can be fitted with double guide rail automatic coupling installation system, providing great convenience to installation and maintenance, so that it doesn’t need a man to get into the sump.
?. It can be operated within full head, with no overload of motor.
?. Two types of installation, fixed automatic coupling installation system and traveling free installation system.
