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:When using a frequency converter to adjust the pump, what is the relationship between the change of the speed and the efficiency of the pump?: First, the wind pumps such load is usually called square torque load, which is in a certain range of speed and torque is roughly proportional to the square of the speed of N, TL=kn^2, power and speed is proportional to the cube, the energy-saving effect is obvious. Can also be described according to what you pump model, the pump is divided into piston pumps, screw pumps, impeller pumps and centrifugal pumps.Secondly, under the standard condition, the higher the efficiency of the centrifugal pump, the higher the speed determines the size of the centrifugal force, the higher the speed, the greater the centrifugal force, and vice versa. Plunger pump and screw pump is not the same, the speed of speed and efficiency basically no impact. Third, in addition to buying the pump, you can let the manufacturer give you an FM curve, so you can see the frequency of mediation when the water pump efficiency changes

Q:Can the water from the fire pump enter the roof fire tank? Why?: This should be divided into two cases, the key depends on the use of your water tank!If you fire water tank roof is a constant pressure water tank fire control system, the requirements must be set on the water tank outlet check valve, which can only flow from the tank outflow, then pump the water can not enter the roof fire water tank.If the roof fire water tank acts as a water transfer tank and uses it to transport water to a higher building, the fire pump water can enter the water tank

Q:The pump assembly and the pump are not a thing: Water pump components: stator, rotor, bearing, shell, sealing system, under their own consideration

Q:What is the function of the backflow pipe of the fire pump?: Generally, it is used to test the fire pump. The procedure is to start the fire pump - turn on the return pipe - return the water to the pool. The purpose of the installation is to prevent damage to the pipe caused by the excessive pressure caused by the pump.

Q:What are some good brands of aquarium water pumps? I have had bad experiances with Hydor Seltz (cheapest ones I could find, ugg, I know, you get what you pay for) pumps, failing very quickly, and sounding like plastic gears grinding around inside. What is the best kind to get?I need one that's around 150gph: i have a topfin that works well for me.

Q:I getting some work done to my like replacing the timing cover gasket, oil pan gasket and the water pump gasket...the mechanic I talked to said I need to replace this as well; my thing is the water pump is fine..should I take his advice?: some vehicles have diverse designs. The water pump on my ninety six Century would have been finished in a rely of minutes. the place as some are plenty deeper in the engine. frequently, to alter a water pump like that's rather plenty one greater step than changing the timing belt. for this reason it quite is mostly a great theory to do them the two at as quickly as.

Q:How to introduce water pump?: A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.A pump is a machine that transports liquids or pumps liquids.

Q:The water pump gasket in my '98 Forester (130k) recently began to leak, and I will be replacing it in the next couple days. I noticed a stream of bubbles in my overflow container, though, and am wondering if it might be bad head gaskets making the air bubbles. The bubbles only appear after the engine is warmed up, like after a drive around town - there aren't any bubbles when the engine is cold.Is it possible that these air bubbles are coming from the leaking water pump? I hope so, because I'd much rather replace the pump than the head gaskets!: I have yet to witness a leaky water pump suck air into the cooling system . If you are seeing bubbles in your radiator after the vehicle heats up see if the temperature is also higher [the hot gasses will heat up your coolant and eventually can push your antifreeze to the reservoir tank ] it can result in boil over.I strongly believe you have a bad head gasket that has not entirely blown yet Have the compression checked per cylinder,and for water getting into your oil (it would become a milky brown and become frothy a little bit) if that is all ok, then maybe just maybe a pump sucking air is occurring, though I have never seen it or herd of it before in my entire life.

Q:I just had my water pump/timing belt replaced and oil change. When the pump failed, white smoke was coming out, which I figured out to be coolant from the smell. Now there is smoke coming out from under the engine, which I believe to smell like oil. Also, the temperature gauge goes up to the halfway point when I am at a stoplight or idling. The highest I have ever seen it is at 1/3.I had my car serviced by the dealership and I asked them. The man said its burning oil residue from the oil change and that it will burn away in a few days. Is this true? I have had my car worked on and oil changed for the past year at this dealership and have never had any smoke or other problems. What else could be going on? Worse case scenarios. Thanks everyone.: Oil residue ought to go in a few hours, not days !!! Anyway, if the smoke persists then it seems that youv'e got a cracked engine gasket and oil is mixing with cylinder water. Check it and check your radiator for any clogs.

Q:does anyone know the proper way to take the lower gearcase off and install a new water pump kit. it is a 1986.: This is a simple repair but I'd recommend that you get a service manual, ether a factory manual or one of the generic Seloc manuals. The key things to do are mark the trim tab so you can put it back in the same position after repairs. Drain the oil. Removing the bolt that is in the hole at the back end of the upper housing, as well as all the obvious Nuts. both above and under the cavitation plate. Put the drive in forward gear, which takes the tension off the shift shaft. Once all the nuts and bolt are loose. Jiggle the drive and it will separate from the upper housing. You now have access to the water pump housing. Remove the housing and pull it up and off the d. Shaft. Inspect fully and account for missing impeller blades. When you re assemble Lube the impeller and put the drive key in place and put the impeller in place. Slide the housing down to the impeller. You can use ether th drive shaft or the propeller to turn the drive shaft in a clockwise direction as you apply pressure on the housing, It should slide down over the impeller. Reassemble in reverse order. Slide the drive shaft up into the upper housing turning the D. shaft using the prop to turn the shaft. Watch the water tube slip into the guide tube. Once it's in place put a couple nuts on then check the gear shift to make sure it goes F-N-R. Bolt up and fill with oil. Good Luck!
