Product Description:

1. Product Introduction

WQ series submersible sewage pump is mainly used for municipal work, industrial building, hotels, hospitals, civil air defense, mines, etc. It can be widely used in transfer waste water, rainwater and living water etc. which contains solid grains and various long fibers CNBM WQ series sewage submersible pump have many advantages, such as, hi-efficiency, circumvolution proof, blockage free, auto-coupling, hi-reliability and auto-control, etc.

Capacity: 10~8000m³/h

Head: 5~60m

Power: 1.5~315kw

Diameter of pass solids: 20~145mm

 

3. Operation Condition

1). Rated Voltage: 380V(660V), Frequency: 50Hz, 3-phase AC.

2). Temperature of medium under 40ºC.

3). PH value: 4~10.

4). Volume ratio of solid in medium below 2%.

5). Density of medium should be lower than 12000kg/m³.

 

4. Structure Characteristic

WQ series submersible sewage pump is equipped with status indicator and protection device to ensure for pump safe and reliable operating.

1). The unique cable airproof is adopted, avoid leakage of cable.

2).  Heat protector in stator assure of operating life of the motor.

3).  The pump adopts outer recycling cooling design with motor power more than 18.5kw, which can keep the pump operating safely under the lowest water level.

4).  A floating switch is installed at the bottom of motor chamber to protect the mechanical seal in the motor side.

5).  The oil-water probe is installed at the up end of the oil chamber between pump and motor that can protect the mechanical seal in the side. If leakage occurs, the system will signalize and start protection.

6).  Adopt perfect mechanical seal, the sealing material adopt tungsten carbide, silicon carbide and hard metal alloy, which can prevent the water from entering into the motor, and keep the operating reliable and safety.

7).  The auxiliary impeller can balance the pressure outside of the mechanical seal, prevent the water entering into the oil chamber and prolong the life of the motor.

8).  Unique impeller design, wide passage allow large solid and long fiber passing through freely, it features non-clog, convolve-proof and good passing ability.

9).  The changeable wearing ring is installed between the impeller and the volute to keep the optimum operation conditions.

 

5. Impeller Design Characteristics

For the feculence pass freely, it must be widen the flowing passage of impeller, for the big pump, can used for double-vane, or three-vane, for the small pump, it used for single(double) flowing passage, like a bent pipe has same section, it has a good passing characteristic, avoid stop, convolve caused by slowing current possibly. The especially flowing passage of impeller, cooperate with logical volute, made the paper, soft goods, garbage bag and other material in sewage can passing freely and the pump have no vibration in the course of running-in and load through the impeller balance between dynamic and static state.

 6. FAQ for WQ pumps

1). Can I get trained on CNBM products?

Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

Q:Two pumps automatically switch start control circuit,
The puddle is full, the float switch is closed, and the relay J1 works to drive the first motor. The J1's work makes the intermediate relay 'J' work and locks itself, preparing for the work of the second machines. The water level is lowered to the required minimum position, the ball is broken, the motor is stopped and the motor is stopped. When the water level rose to the highest position again, the floating ball closed again, the relay J2 and self-locking relay J2 to drive second motors, instant intermediate relay are opened, when the water level again be reduced to the lowest position, float off, the motor stops working, stop by working in front of the intermediate relay. The whole circuit back to the original state. So that the two motors work alternately.It should be noted that the circuit diagram for simple to understand, only painted the control circuit, there is no main circuit, there is no missing phase, leakage, over-current and other protection, the actual installation needs to be installed. There is the role of time relay is to ensure that the relay J2 normal work, the intermediate relay is disconnected, so that the motor 2 does not occur wrong action, time relay can be set to a few seconds, or even less than a second. Intermediate relay can also be controlled by time relay, and its time is also set very small, so as to avoid J2 short time possible power supply.

Q:2000 Chevy Impala with a bad water pump?
It sounds like a water pump or maybe a loose connection. It is probably time for a water pump if it hasn't been replaced yet. Parts will run under $60 and it probably involves an hour of labor. The Impala is a big car, it shouldn't be hard to get to and remove. Taking it to a shop will run under $100-$150 for everything.

Q:can a non-mechanic replace a water pump?
Unless you have a lot of experience doing mechanical repairs this is not a job for amateurs in most cases. I am not familiar with the engine in question but unless it is a bolt on external unit I would pay someone to install it.

Q:What is the function of a submersible pump?
Submersible pump motor and pump is directly connected with the water pump body into the water to work, it is suitable for the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects: mainly used for irrigation and plateau in the drinking water, but also for the city, factories, railways, mining and construction site the use of water supply and drainage.Characteristics of submersible pumps for well1 、 motor, water pump, submerged operation, safe and reliable.2, the well pipe and pump water pipe without special requirements (i.e.: steel tube wells, tube wells, Doi ash can be used).3, installation, use and maintenance of convenient, simple, small footprint, do not need to build pumping stations.The structure is simple, and the raw materials are saved.4, submersible pump conditions are appropriate, properly managed, and has a direct relationship with the service life.
Q:how much does it cost to change a timing belt and water pump on my a car?
The timing belt needs to be change according to the manufacturer's maintenance schedule. Lacking that knowledge, 60,000 miles is a safe interval. The water pump does not need to be changed unless if fails. It's not possible to quote a cost on changing either. Some are fairly quick and easy -- SOHC I-4s without the silent shafts can be as little as $150.00 for the timing belt, and about the same for the water pump. A bit less if both are changed at the same time, possibly. A more complex engine such as a DOHC 4 with silent shafts or a DOHC V-6 or V-8mcan be much more expensive -- several hundred $$$ or more because there may be multiple belts and getting the timing right is a chore. A few are downright nasty as the engine needs to be pulled to get enough room to work on them -- early Hyundai Sonatas were that way. Any competent mechanic can do the job, you don't normally need to go a dealer. That said, the dealer is likely to have factory trained staff and may be familiar with shortcuts and have any special tools needed. The exact procedure is specific to the individual engine. You need a service manual to get it right. Cam timing is hyper-critical. Mess that up and at best the engine won't run. At worst, you can destroy the engine if valves hit the pistons.

Q:Does the IP55 indicate the lift on the water pump nameplate?
IP is INGRESS PROTECTION, that is, protection level,IP protection class is composed of two numbers, first numbers, from the lighting level to prevent intrusion of foreign objects, second numbers represent the tightness of anti moisture, waterproof lamp intrusion, the larger the number the higher the level of protection.Therefore, the pump IP refers to the pump with its own motor dust and waterproof level
