1. Specification For WQ Submersible Sewage Centrifugal Pump

1) CE,GS,ROHS,ISO9001.CC
2) With aluminium pump boby,anti-corrosion
3) Sewage pump
4) Dirty water pump
5) Water pump

2. Product Introduction for WQ Submersible Sewage Centrifugal Pump.
WQD WQ type submersible sewage pump/dirty water pump consists of pump,mechanical seal and motor.Pump is at the bottom part of motor pump,which adopt centifugal impeller. Motor is at the upper part of motor pump and is a single-phase asynchronous motor or three-phase motor.Mechanicalk seal is between pump and motor,and it'sa kind of double end mechanical seal."o"rings are applied to all static joints of the submersible pump.Inner-installed protector prevents the pujmp from damages due to abnormal power,colg and overload etc.

3. Working Condition of WQ Submersible Sewage Centrifugal Pump.
1) Transport liquid water temperature is less than +40°C
2) The PH value of the media is between 6.5to 8.5
3) The volume per centage of impurity in the medium is less than 0.1%,grain smaller than 0.2mm
4) Pump should be rated near lift the appropriate range,submersible pump head can not be too low,below the stiplated 80%of head easily lead to thermal protector,so that pumps stopped running,and even cause electrical damage.
5) Diving depth of no more than 5m.

4. FAQ for WQ Submersible Sewage Centrifugal Pump
1) Are CNBM pumps available in DIY stores?
Yes, currently, we’re available for DIY stores all over the world.
2) Where do I have to send pumps for service?
You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.
3)Are your pumps acid-proofed?
To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.

WQ Vertical Sewage Centrifugal Submersible Water Pumps

Q:What are the application areas of pumps?: 1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system

Q:What is the working pressure of the hydraulic pump in the hydraulic transmission system?: The operating pressure of the hydraulic system depends mainly on the load. Generally speaking, the working pressure of the hydraulic system means the highest working pressure of the system. If the pressure is higher than the value of the equipment, the relief valve works to relieve pressure. The actual working pressure of the hydraulic system is determined by the load, which refers to the actual pressure of the hydraulic oil and can be read directly from the pressure gauge. The pressure increases with the increase of the load. You Li's balance can know: the thrust of the cylinder = the load, the thrust of the cylinder = the working pressure of the hydraulic oil, the working area of the cylinder, the working pressure = the load / the area of the cylinder.

Q:Does the reservoir water heater press the booster pump (high marks)?: In addition, the water storage electric water heater has a safety valve is O.7MPa, before buying a booster pump, you can check the water inlet valve spring weakness, see the effect of water, barely even, then use it, do not buy.

Q:Know flow and lift how to calculate the pump power?: The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.

Q:Do you have a suction pump higher than 9 meters?: This screw self-priming pump suction process can be more than ten meters or more, my family is using this

Q:Common failure treatment of piston pump: x09x09 (3) no connecting key on pump shaft or motor shaft1) break2) missing x091) replace key2) patch keyx09x09 (4) pump internal slide vice stuck1) the clearance is too small2) parts accuracy is poor, assembly quality is poor, gear and shaft coaxial deviation is too large; plunger head clamping; blade perpendicularity difference; rotor pendulum difference is too big, rotor slot has wound or blade has scar, force after fracture and stuck

Q:Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?: Household automatic booster pump is not started by pressure, it is induced water pump, that is boiled water faucet

Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system? How to choose in the project?: Pump control system is generally used for closed systems, the flow of the oil pump changes to control the motor or cylinder actuator action. The utility model has the advantages that the principle is simple, and the power of the engine can be fully utilized. The disadvantage is that the calorific value of larger, relatively poor precision.

Q:What does "dual purpose" of water pump mean? Please expert advice: In order to ensure safe and continuous operation, three pumps usually need two units and run one standby.Precautions for using pumps1, if there is any small water pump failure, remember not to work. If the pump shaft packing end wear should be added in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller.

Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?: The unit of displacement is the milliliter. How many milliliters does the pump rotate per circle? The displacement is the pump, the individual,The unit of flow is generally a liter, a figure added to the displacement of the pump over a period of time,
