概述：

CRQW潜水排污泵系列是我公司引进国外先进技术的基础上，结合国内水泵的使用特点而研制成功的新一代泵类产品。适用于工厂和商业严重污染废水的排放，住宅区的污水排污站、城市污水处理厂排水系统、人防系统排水站、自来水的给水设备，医院、宾馆的污水排放、市政工程建筑工地、勘探、矿山配套附机、农村沼气池、农田灌溉等行业，输送带颗粒的污水、污物，也可用于清水及带腐蚀性介质。输送液体的流量范围为7~10000m3/h扬程范围为7~60m，配套功率范围为0.55~315KW，口径范围为φ25~φ700 mm。

使用条件

A、介质温度不超过60°C，介质密度最大为1.3×103kg/m3；

B、无内自流循环冷却系统的泵，电机部分露出液面不超过1/2；

C、输送介质的PH值为4~10；

D、污物通过能力：固体颗粒为进口口径的60%，纤维长度为进口口径的5倍。

型号说明

示例：100CRQW100－15－7.5

100：泵排出口径为100mm

CR：企业代码，表示由湖南凯利特泵业有限公司生产

QW：潜水式排污泵

100：水泵额定流量为100m3/h

15：水泵额定扬程为15m

7.5：为配用电机功率7.5KW

水泵特点

一、采用独特的单叶片或双叶片叶轮结构，大提高了污物的通过能力，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；

机械密封采用新型号硬质合金耐腐蚀材料，同时将密封改进为单端面双机械密封，使其长期处于油室内运行，可使泵安全连续运行8000以上

二、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；

三、该泵密封油室内设置有高精度抗干扰漏水检测传感器，及定子绕组内预埋了热敏元件，对水泵电机绝对保护；

四、可根据用户需要配备全自动安全保护控制柜，对泵的漏水、漏电、过载及超温等进行绝对保护，提高了产品的安全性与可靠性；

五、浮球开关可以根据所需要液位变化，自动控制泵的超动与停止，不需专人看管，使用极为方便；

六、可根据用户需要配备双导轨自动耦合安装系统，它给安装、维修带来了极大的方便，人可以不必为此而进入污水坑；

七、能够在全扬程范围内使用，而保证电机不会超载；

八、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。

Type CRQW Submersible sewage pump

General Description

Type CRQW submersible sewage pump is newly developed on the basis of the advanced technology from international. Is used for industry and commerce, the living area，urban sewage treatment plant, waterworks，civil air-defense construction，hospital，hotel and so on. They can also be used in public works, explore, country methane, irrigation, deliver water with impurity. The flow-rate range of the delivery water is 7-10000m3/h, lift range is 7-60m,power range is 0.55-315KW, caliber range is φ25-φ700 mm.

Service conditions

 Medium temperature should not above 60°C, Maximum density is 1.3×103kg/m3.

 If the pump without a build-in self-circulation cooling system, its motor should not expose above water more than half.

 Deliver medium’s PH value is between 4 and 10.

 Solid particle passing capacity is 60% of the inlet diameter, the length of the fiber is 5 times to inlet diameter.

Instruction of pump type

Example: 100CRQW100－15－7.5

100 in the front: Pump outlet diameter is 100mm

CR: Company code, means produced by CREDO PUMP

QW: Submersible sewage pump

100 after: Flow capacity 100m3/h

15: Head is 15m

7.5: Motor power is 7.5KW

Structure

Type CRQW Submersible Sewage Pump adopts particular single blade or double blade; advance the ability for get across feculence. Fiber about 5 times as pump caliber can across.

Mechanical seal adopt fresh model cemented carbide rot-proof material, and at the same time, we improved on the airproof to the single-ended double-face mechanical seal, let them work in oil chamber for a long period of time.

The whole structure is compact;, volume is small, little noise and the energy saving result was apparent. The machine needn’t pump room .It can work just dinning into water, so reduce project cost.

According to need, we can equip safety protection control cupboard to protect the pump, advanced the safety and reliability.

The float switch can control automatically, do not need specially-assigned person. It’s very convenient.

According to need, we can equip automatic coupler installation system. So people needn’t get into the drainage ditch.

Can be used in all the range of lift ,and it won’t overload.

There are two different install way, fixed type automatic installation system and movable type automatic installation system.
