Description
Submersible aerators are used in aeration tanks and aeration depositing tanks of waste water treatment plants. They oxygenate the mixture of waste water and sludge and treat the water by biochemistry or oxygenate the breeding pools. Air input: 10-100m3/h, oxygenation capacity:0.35-8.20kgO2/h, motor power: 0,75-7.5kW.
IDENTIFICATION CODES
QXB－ QXB- Centrifuge submersible aerator - Motor power (kW) QSB－ QSB- Jet submersible aerator - Motor power (kW)
CHARACTERISTIC
1.Compact structure, small area occupied, easy to install;
2.Except for the air inlet, all the parts are in water and noise level is very low;
3.More air intake, more and small bubble produced and high oxygen dissolution;
4.Not necessary to provide air source, no air blower and engineering cost is fairly low;
5.ABS submersible technology imported from Germany is adopted. The flow channel of the impeller is adopted of blockless and the operation is safer and more reliable.
STRUCTURE AND OPERATION PRINCIPLE
The submersible aerator is composed of submersible pump, mixing compartment, pedestal, air inlet tube, muffler, etc. For the air inlet tube, the upper side is the air inlet above the water surface and the lower side is connected to the mixing compartment. When the electric power is switched on, the impeller shall rotate and the water shall flow out of the impeller outlet. It shall result in minus pressure in the mixing compartment and air shall enter to mix the liquid. The mixture shall flow out from periphery to fulfill the process to oxygenate the liquid
- Q: A guy i know changed the Water pump on my 02 Chrysler Sebring with a 2.7 in it because it was leaking coolant, when i got it back the leak was fixed but now there is a ticking noise. He thinks that the Timing Chain Tensioner needs to be replaced... can i get some opinions here? does he sound correct?
- Most mechanics won't even work on those 2.7 motors! The timing chain tensioners break all the time and after repairs the motor keeps coming back for more. I'd trade that POS before it doesn't run again!!!
- Q: the outboard runs fine and pumps water out with muffs on but when i put it in the water it doesn't pump any water at all. could it be that the impeller needs replacing? what do you think?thanks
- No question about it. Replace the impeller. It's easy - the hard part is getting the fasteners off without breaking a stud. Be patient and use liquid wrench and give it an hour or more to work. Tap the nuts and then try them. A final resort would be careful (very careful) use of a propane torch to free the nuts. If not replaced, eventually blades will break off the impeller and foul the cooling system.... which can be a very expensive and difficult repair.....overheating is also very bad for the engine.... so fix the water pump.
- Q: 1.5 kW three-phase pump with 600 meters line, should match what big line?
- Resistivity of copper conductors is 0.017 ohm mm / m, R= P L/S, the resistance can be obtained by 600 meters 2.5 mm - single stranded conductor is 4.08 ohms, and rated current 1.5KW three-phase pump is about 3A, so the pressure drop resistance of the wire leading to the U=4.08X3=12.24V. So if the supply voltage can be stabilized at 380V~400V, with 2.5 mm - cable; if the supply voltage is between 370~390V, with 4 mm - cable. (above is copper core, aluminum core shall be increased by 1)
- Q: It stops and every few minutes and when it stops, it sounds like water is running.
- Ok lets go down the check list. 1) Is your cut off switch working good? Turning on and off at proper set pressure. (I don't know what you may have yours adjusted to. Mine is on at 70 off at 95.) 2) Is your expansion tank (or pressure tank) water logged? Knock on it. Does it sound full or partially full. Full is bad. You will need to shut off the water pump, close off any outgoing ports to the rest of the house, open the drain valve nearest that tank, and press your finger into the shraider valve at the top (the thing that looks like a tire stem valve). Drain the tank only. Then turn the water back on. 3) Do you have water softeners hooked up? Listen closely to the discharge tube. (this may be where it is coming from). IF you hear a leaking it is because the valve spring inside and washers need to be replaced. 4) do you have any other whole house filters? If so check the discharge tubes of them. 5) Do you have a reverse osmosis filter? IF so this is supposed to drain and you will hear it constantly. 6) Look for any water puddles 7) IF all these fail, then replace your water pump.
- Q: water pump pulley has slight wobble in it. not seeing water yet....is bearing going bad
- Could be several things. The pulley is not on straight. The pulley itself is not truly flat when made but still within tolerances allowed by manufacturer. .Has nothing to do with the bushing(bearing) They generally wear out over time and start leaking coolant out.
- Q: i'm changing the tyming belt the vehicle has done 120,000 km should i replace water pump as well
- Hi strange you say this it seems like when ever a timing belt is changed on a toyota the water pump is always an issue, i was warned that the same is true on my land criuser that the water pump may need to be replaced when the timing belt is changed.
- Q: Would I notice a difference in driving if I changed my timing belt and water pump?
- Yep thats approximately good and those aspects are the lifeline of the motor vehicle the timing belt turns the motor and the water pump pumps the coolant with the aid of the engine. purely the pump and the belt plus different seals and and so on aspects is gonna run approximately 4 hundred+ in case you think of you're able to do it your self yet with the aid of fact it relatively is a greater luxurious acura yeah one thousand sounds good. i purely did my integra and that they quoted me i think of six hundred yet I did it myself for decrease than the cost of the climate.
- Q: My dads needs a new water pump for his '83 Silverado v8, anyone have a DIY or a schematic or know of where I can find one? Maybe someone could tell me how. He's pretty handy with cars just doesn't know what needs to come off and in what order. -Thanks in advance!
- remove the fan shroud , then the then belt, then the fan. drain coolant then remove hoses from pump. then the water pump .. it is a 2 hour job at most . can be done as little as a hour if you have the right tools and understand the job. you will need special too to remove fan. rest is 10mm 13mm , 14mm or 15 mm bolts .. press clamps need pliers or flat screw driver to remove clamps .
- Q: The pump works and water goes to the house from the reserve tanks but there can be long delays before it cuts in after mains pressure is lost. After it stops the pressure gauge falls back slowly to zero. Pressure vessel is a sphere has a valve on top. Any suggestions ?
- Sorry I don't know the Espa make but the theory is the same...if the pressure falls once the pump stops,that sounds like a leak in the lines somewhere (most probably the foot valve needs repacement.the fact that the pressure falls to 0 lbs would mean either that the pressure switch is not set properly or it also needs replacement.normal settings for household systems are either cut in at 20lb cut out at 40lbs or cut in at 30lbs and cut out at 50lbs.Check your pressure tank if its got a bladder it should be pressurized to 2lbs below cut in pressure this should be done with the pump off and no water pressure.IF your tank is a non bladder model empty it completly and then prime and restart the pump.
- Q: i need to know an estimated cost for changing this cars water pumpthanks..
- Too okorder i did this, and by doing so it saved me money, time, and the risk of getting ripped off.
