Product Description:

WQ Series Sewage Submersible Centrifugal Pump

 

Product Description:

1. WQ series Sewage Submersible Pump Introduction details:

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.

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.

 

3. WQ series Sewage Submersible Pump Technical Performance details:

Discharge diameter: 50~600 mm

Capacity: 10~8000m³/h

Head: 5~60m

Power: 1.5~315kw

Diameter of pass solids: 20~145mm

 

4. WQ Series Sewage Submersible Pump Structure Characteristics details:

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 Designs Details of Sewage Pumps:

For the sewage to 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 regarding WQ Series Sewage Submersible Centrifugal 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.

2). Are your pumps cheaper than those of your competitors?

Q:How do you do the yellow water from the suction pump?.
The reason for the yellow water in the water suction pump is that the steel pipe in the underground is corroded. The water flows out through the water during the pumping process, and yellow is mainly the color of rust.Processing method: pull out the steel pipe deep into the ground and replace it with plastic pipe.
Q:Difference between primary hot water pump and two hot water pump
A hot water pump is a water pump circulating between the boiler and the heat exchanger, and the two hot water pump is a circulating water pump between the heat exchanger and the user. That is, there is no relationship between a water pump and heating users.
Q:How to select the pump model?
70 degrees or so on the steep slope pumping 170 meters, vertical height of about 100m, you can choose the lift 120-150m of multi-stage pumps, nominal diameter 1 inches, 2 or 1 inches and a half can be.The power consumption of about 1520kW.
Q:Does the water pump and the circulating pump belong to the centrifugal pump?
Water pumps are generally centrifugal pumpsThe circulation pump depends on what kind of liquid it is circulatingGrease is generally gear pumps
Q:What are the new regulations in the design of main and auxiliary water bin and water pump room in coal mine?
The main water bin must have a main bin and an auxiliary warehouse. When a sump is cleaned, another water tank can be used normally.When the normal water inflow is below 1000m3/h, the effective capacity of the main water tank should be able to accommodate the normal discharge of 8h.The effective capacity of the main water bin can be calculated by pressing type in the mine where the normal water inflow is greater than 1000m3/h:V = 2 (Q+3000)Effective capacity of V-- main water bin in type m3;Q-- mine hourly normal water inflow, m3.However, the total effective capacity of the main water storage tanks shall not be less than the normal water inflow of 4h.The effective capacity of the water tank in the mining area shall be able to accommodate the normal water inflow in the 4H mining area.There is a big difference between the maximum water inflow and the normal water inflow in the mine. The drainage capacity and the water storage capacity should be specially designed.The water inlet chamber should be set up. A sedimentation tank shall be provided for the filling of water sand, hydraulic coal mining and other gushing water with a large amount of impurities. The water storage capacity of short positions must often remain above 50% of total capacity.
Q:55KW how large is the water pump wiring?
Transmission within 100 meters, 70 square millimeter aluminum cable, or 50 square millimeter copper cable. If you exceed 100 meters, you'll have to add a number to the cable.
Q:50 meters deep well with what water pump: home?
For deepwater submersible pumps, ordinary submersible pumps are inefficient.
Q:What's the water pump?
Whether frozen water pump or cooling water pump, including the boiler with the water pump, as long as it is used for replenishment, are called water pump. Normally, the pump works intermittently.
Q:How do I calculate the power of the pump?
A 15kw pump, know how to calculate the head pumping water for an hour (if the head is 10 meters)Lift: MFlow rate: kg / sec (general water pump is cubic / hour, if 10 cubic hour / hour: 2.7 kg / sec)Efficiency: average 60%15000/102*0.6=88 kilograms per second88/10=8.8 kg / sec8.8*3600=31680 kg / h=31.6 cubic / hour
Q:Do you need a stop valve for the pump at home?
It is better to connect with the pump. If it is a self suction pump, it can not be connected, but when it is pumped, it does not immediately have water, and the submersible pump is not necessaryMy home is a self suction pump, fully automatic control, I took the check valve, in the pump suction port position is very good, as long as it has started, there will be water out
