Non-negative Pressure Water supply systerm
Summarize

water supply systerm in a building is our new design, which is used for building water supply, fire fighting, flood, water supply station and so on. The systerm is controlled by Variable-frequency Drive, VFD.

Once you have this pump systerm, you do not need pump station any more, especial using in Prairie, Desert, city water supply, if the water source changed, you only move the pump container will be ok.

Main Features

1.1. Automatic control of constant water pressure

2.2. Set the pressure directly in the operator.

3.3. Built-in pressure or flow sensors, water level switch signal interface.

4.4. P.I.D control unmanned automatic monitoring of water pumps stoped function (dormant).

5.5. No need to configure the PLC can realize automatic alternating pump function.

6.6. Power outages or low water level automatically actived after the restore operation.

7.7. Controlle by thermostat.

8.8. Many pump-linked run-time, regular rotation as the master pump,so that the pump balanced working hours to prevent the pump speed of die wear and rust.

9.9. Adequate operation status monitoring, and complete motor protection features, simple operation.

10.10. To adapt to a variety of sensor signals:Pressure sensors, transmissible pressure gauge, eletric contact pressure gauges and pressure switches.

Full-automatic Control (Easy and Safe Controlling)

1. Solenoid Valve: Pressure backflow protection

2. Flow Sensor

3.Vacuum Pressure Sensor: Can know the inlet pressure, once the valves all colosed, will start reflux.

4. Flow Switch: if no water pass, the pump will stop working

Q: I am going to replace the timing belt , tesioner and idler bearing on my 2000 daewoo leganza. I noticed some of the kits have water pumps too. It is likely to break like the timing belt?: Well the logic is that since you only need to replace the timing belt every 60,000 miles, then you might as well change the water pump, should it fail in between you would end up having to do nearly the same job all over again. always change the water pump if it is driven by the timing belt. That is purely a rule of the trade.

Q: Is it cheaper to run an electric water pump or a furnace?: If you live down south in the good old USA, yes it is cheaper money wise. Initial start up costs can be really steep though. I just saw a great system that has solar power along with the geothermal that was $15,000.00 You may want to own the house and I hope it is worth it as it will be awhile before you even out on the costs. This was a 3000 square foot home I saw the system in, so it may be cheaper, BUT, may even be MORE to install because your place may be smaller and what are local regulations ? Good Luck.

Q: Two sewage pumps switch from each other, start with float switch control, the first sump, when the water is full, the first start, the second rotation to second units start, so the cycle of alternating: Do you mean that 2 pumps are used in a hole? With float switch control, plus time relay 24 hours, every 12 hours at will, you set time, seconds, minutes can be

Q: Variable flow variable frequency water pump how to adjust the flow?: Flow plus transmitter control

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: I tried using my water line with a pressure tank and pressure switch but without a pressure tank I observed that when he pressure reaches 30 psi the motor pump switches off automatically and when we open the faucets to use water the pressure switch turns on again the motor pump.: Never use a water well pump system without a pressure tank. The tank performs several functions - when it is in good operating condition. You want a specific amount of run time and off time on the submersible pump that will bring your water system and tank to a set pressure range. And as said, it is a buffer to eliminate surging. Plus permit a proper cycle time. Most standard water systems are set in a 20 pound differential. It is frequently set to pump at 30 PSI and shut off at 50 PSI or pump at 40 PSI and off at 60 PSI. 30 PSI is quite a low setting on the pressure switch Defective pressure tanks are very common and when they go bad, the risk of damage to the pump is at hand. There are very specific criteria to follow for a water well system. Too many variables to list here It would be best to have a reputable water well service person assist you. Pulling a defective submersible pump is not fun or inexpensive. Make a call - you will be glad you did in the long term.

Q: My Camry is overheating and I am assuming it is the water pump. I already changed the thermostat and that was no help. When I turn the heater on to cool off the engine, it blows cold air or the temp of the air outside most of the time and seldomly hot air. I bought a water pump, but I am not sure if this is something I can do?: Step 1: Find a man

Q: Any ideas on where and what type of water pump I should use for my 29 Gallon BioCube tank? It seems that the water pump is very loud and is not working the way it should. There are bubbles shooting the aquarium and I have tried everything to fix it. I am thinking of replacing the water pump all together. Any ideas on brands that would be compatible? Anyone else tried this? Please help...: ok before replacing have you cleaned the inside, and if there are air bubbles comming out it is because it is running dry. Basically all biocubes do this, the filter pad is slowing down the water too much, so either rince it well or replace it. Also i would wash out the blue sponge right before the pump as that can hold alot of dirt as well. Then if not add more water. But if you want to replace the pump, try via aqua water pumps. they tend to be the best. owner of the BC 29 and BC 14

Q: I have a Stamas boat that I am in the middle of restoring. It has 2 chevy 350's, with borg warner (sp) tranny's, and v-drives. Anyway, it has standard water pumps to cool the engines, and it had 2 Sherwood pumps to circulate the water to cool the tranny's, and v-drives. First, I am using the boat in Lake Michigan only, the water is very cool year round since it is such a big body of fresh water. I was wondering if there was any recommendation on possibly using 2 electric pumps to circulate the water? If so, what would a good unit be? Second, the transmission coolers were brass, with a honey comb in the center for the ATS fluid to run through, and the water would run on the outside to cool the fluid. Is this a more effective way to cool the fluid than with those expensive brass fitting? Just checking before I spend a few hundred on them to see if a better way to cool my engine and tranny's, in all honestly though, I am more worried about effectiveness than cost.: You would be playing with fire to use electric pumps to cool the transmissions and v drives. I doubt they would put out the volume of cooling water needed to cool them and have enough extra volume just in case. Besides, the raw water pumps also would cool the engines and exhaust systems if they are raw water cooled or they would cool the anti freeze and exhaust and transmissions with heat exchangers and oil coolers. Those transmission coolers should be plumbed into the raw water system using the same water that flows through the engines. Not to mention the reliability of the electric pumps vs engine driven pumps.

Q: 2000 Jetta GLX VR6Problems:- AC is no longer working- The Reader said quot;STOP!quot;CHECK COOLANTI pulled over and checked the Coolant and it was full- The Car will overheat to about 260 whenever I am sitting with the Engine Running- When I start the car its on Zero Degrees and then Slowly makes it way to 190 degrees which is in the middle quot;Normalquot;- Oil Seems to be fine---- What does this sound like to you??--- Also, The VW Dealer said I needed to be without my Car for Two days so I will drop it off Friday Night and leave it until Wednesday. Do you think it will last until Friday driving 60miles a day??-- If it is the Water Pump... How much do you *think* I am looking at paying? I am taking it to the VW Dealer b/c I have a Recall they need to fix too.: This does not sound good. If it is the water pump, there is a very good chance that you will severely damage the heads and/or block by continuing to drive it. I would not drive it at all, unless you want to risk the expense of a re-built engine (more than $5000 plus installation). If it is the water pump, and not covered under warranty (and I would really get on them about that) less than $1000.
