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 of WQ Series Sewage Submersible Pump 

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 of WQ Series Sewage Submersible Pump

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 of WQ Series Sewage Submersible Pump

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

Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
(1) pump connected outside pipes, containers, pipes, joints and other leakage test instrument, large leakage, rotary gas plug exhaust sound big, and the gas and oil mist discharge, should find leakage cancellation.(2) the assembly of rubber of intake pipe is not proper, damage or aging should be adjusted or replaced.(3) plug hole, the vacuum degree can be decreased, put the oil, remove the tank, loosen the nozzle plate, pull out the oil inlet nozzle, dredge oil hole, try not to use cotton wipe parts.(4) the vacuum system has serious pollution, including containers, pipes and so on. It should be cleaned.(5) the spring of the vane is broken and should be adjusted.
Q:What is the "variable" of a variable pump?
Variable pump variable refers to the flow can be changed to distinguish from the constant flow of quantitative pumps.
Q:Must the water pump in the tank be all soaked in water?
Need a submersible pump in the water, but it is not entirely like this, I have to work for a long time no problem in water, but there is a problem you should pay attention to the water pump, at least in half, or stop when the smoke is not on water.
Q:What's the meaning of the pump head in the water pump, please advise, thank you
In general, the pump removes the motor, and all the fittings are part of the pump head.A pump is a machine that transports liquids or pumps liquids.
Q:Double floor sewage pump circuit diagram of a small problem
Question 4 when you need backup, you need to switch the SA switch, but where you want it. For example, when the 1# pump is running and does not reach the high water level, the 2# pump will not operate. If SA is placed in the left position, 21 and 22 are connected, and the KT is electrically delayed, and the KAB action causes the 2# pump to function. After the KAB operation, the KT will be disconnected, restored to the ready state, and also convenient for KT to restart the power on time, and also avoid the time relay to work on a long-term basis.
Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.
Q:What are the constant pressure pumps?
Constant pressure pump is also called the booster pump, the name is used for booster pump, its main purpose is water heater booster, with tall low pressure, sauna, bath and other pressure in the apartment, the lack of water pressure, solar automatic pressurization and so on.
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact
Q:What's the submersible pump?What is a submersible pump, and what about it?
Deep well submersible pump is a fountain, drinking water transportation, irrigation, hot springs, high-rise transport facilities, etc., deep well submersible pump excellent performance, so widely used in various fields.
Q:What is the difference between centrifugal pump and positive displacement pump?
The centrifugal pump is usually driven by an impeller, and the head has a functional relationship with the flow rate. Positive displacement pump is gear or piston drive, each stroke output flow is constant, and the head does not matter, the pressure head can be infinite.
