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.

 

2. Technical Performance

Discharge diameter: 50~600 mm

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

Q:I have a small drip coming from the raw water pump, whats the problem?
Usual answer is to look for the flats of the gland on the shaft on tighten up with a spanner,as this will compress the packing a bit more. A small drip is not very bad but you are right to check.
Q:How much does it cost to get the timing belt changed including:?
You better shop around on that one but you're looking at a few hundred dollars minimum. The newer the car, the more you're going to pay to get it fixed.
Q:Pump adapter joint net outside tube, what is the principle?
At once the room after the fire, the internal fire pool once water shortage, the water tank can be within the fire truck hit the water chamber through the pump adapter connected to the fire extinguishing effect.
Q:Acura 1.7 EL Timing Belt and Water Pump replacement?
The timing belt is what runs off the crankshaft gear to the cam gear and also turn your water pump.. If this belt breaks. the engine dies, and most often the engine gets out of time, causing the valves to bend, and sometimes come in contact with the pistons, The cost of repair in ALABAMA is 650.00, this is parts and labor. and it is recommended every 90k miles.. also I recommend replacing the water pump, and doing a valve adjustment..I a simple form of words...belt breaks, engine stop running...
Q:94 Max leaking coolant. Drips from around the belts next to engine.Is this Water pump issue?
Water pumps should be replaced every 60K miles and the timing belt should be done at the same time. If your water pump hasn't been replaced in that long or longer I'd blame it having shaft play for your leak. The water pump is in the same area as the belts so it's definitely the most likely culprit.
Q:My car squeaks every time I turn it on. But the belt is tight and I have a new water pump and alternator.?
If your car is a Chrysler product it is most likely the bearings failing in the idler pulley on the belt tensioning arm. I have replaced this after failure on 2 dodge mini vans. Don't wait too long, if it fails completely the belt will be ruined and leave you stranded.
Q:can i drive my car to a service center 5 miles with a blown water pump?
Absolutely not. You'll most likely end up blowing the radiator. A great amount of pressure can/will be built up in the radiator and that's not good. I had the water pump go out in my Mazda MPV and didn't know it. I was going up the expressway and just so happened to notice that my temperature gauge was in the red and then I heard a pop and water and steam came shooting up from underneath the hood. You can usually only go about a 1/4 to 1/2 mile with a blown water pump. You'll have to get it towed.
Q:New water pump and radiator for 2000 Jeep Cherokee?
which may be a blown head gasket, or worse, a cracked block or head. with the engine cool get rid of the radiator cap and fill to the brim. depart the cap off, hearth it up and look ahead to a slow yet stable circulate of bubbles. in case you have a blown head gasket or a crack the engine will blow combustion gasses into the water jacket. in case you detect this get rid of all spark plugs and look at them heavily. the cylinder with the blown gasket could tutor discoloration or an infection on the plug. you additionally can do a compression attempt, or extra helpful yet a leak down attempt on all cylinders to locate the undesirable one. in case you detect the bubbles you will ought to pull the pinnacle. A blown gasket will happen as a discolored section next to a cylinder.
Q:How should the water pump breaker be selected?
If it is a single-phase motor, rated current is 75A; three is about 30A; the contactor should be 1.1-1.5 times the rated current of the motor protection type selection of circuit breaker, circuit breaker: RMM1-100/33002 or 50A motor comprehensive protector, the price is not expensive.The circuit breaker (English Name: circuit-breaker circuit, breaker) refers to the closing, carrying and breaking current conditions and normal circuit switch device, load and breaking current loop abnormal conditions within the stipulated time. The circuit breaker is divided into high voltage circuit breaker and low voltage circuit breaker according to its range of use. The demarcation line of high and low voltage is fuzzy. Generally, more than 3kV is called high-voltage equipment.The circuit breaker can be used to distribute electricity, not frequently start asynchronous motors, the protection of the power line and a motor, can automatically cut off the circuit when they occur serious overload or short circuit and under voltage fault combination, its function is equivalent to the fuse switch and less thermal relay etc.. Moreover, after breaking the fault current, there is no need to change the components. At present, it has been widely used.Distribution is an extremely important link in the generation, transportation and use of electricity. Distribution systems include transformers and various high and low voltage electrical equipment. Low-voltage circuit breakers are a wide range of electrical equipment.
Q:Domestic pump automatic shut off the water, but also turn around, stop what happened?
What should have Water Leakage place, check all the toilet faucet is Water Leakage, Water Leakage, water heater and so on, if no problem, to check the pump, which has a check valve, when the valve is broken, can not maintain the pressure, there will be the phenomenon
