Q:99 Cavalier overheating - is it the water pump?
sounds like u have air trapped somewhere or a flow problem water pump not pumping or thermostat not opening do not keep driving it b/c further costly damage can occur this shouldn't take more than a day for a good mechanic
Q:Why does the pump head decrease when the pump flow rate increases?
First of all, the power of the pump is determined by the motor. When the power is certain, work must be done. According to w=mgh, the flow determines mg, the head is h, you think, if the flow rate is large, is the head smaller?. This is theoretical, and at the same time, you see, the water pump characteristic curve can also see that the flow rate increases, the corresponding smaller head.
Q:how many consequence hours can I leave my water pump working?
You are correct Amps x Volts = watts and since there are about 750 watts per Hp then you have a 2/3 Hp motor. Water pumps can be either submerged in the well bore hole or located top side. A top side well pump relies on the air around it to cool the motor. THe motor may not be rated for continuous duty (see name plate on motor) and may only be rated for a limited amount of time it can be run before it needs a cool down period. (Typically motors are rated for continuous duty) Submersible well pumps are located under water in th well and use the water in contact with the motor housing to cool them. Cooling is thus related to the water flow around the motor and the availability of water. Normal well pump usage for a home is for brief periods when water is actually being used and to maintain system pressure. So unless you are constantly watering your lawn your pump should cycle on and off as necessary. Continuous running is a sign that there is a problem such as a leak, worn pump not achieving proper pressure, or pressure switch setting or similar issue not allowing proper shutdown. If you have a submersible well pump it will be very difficult to tell when it is running unless you can hear the motor contactor open and close or have an indicator light. A properly operating water system will pressurize an accumulator storage tank (water pumped into a tank which contains an air bladder that can be compressed). Once the tank is pressurized the pump shuts off and stays off until the pressure in the tank drops. Pressure drops when you use water or if the water leaks back into the well. At which time the pump runs again and tops off the tank. So in a properly operating system shutting off the well at night won't save you much because the pump should not be running. However if you have a leak and the pump is running a lot you can secure the power to the pump at night until you can get the system repaired
Q:Fire pump room is required to set up water pump control room?
What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control
Q:Blown head gasket or water pump?
Pull the oil dip stick if it has little bubbles on it and it is discolored you have a blown head gasket.Then pull your radiator cap when engine is cold, is it full or not? You can not trust what I call idiot lights because they usually come on after the damage is done.You can tell if the water pump is working by letting eng get to normal and grasp the top hose and squeeze it just a little,can you feel water running thru it,if not replace it.
Q:auto repair water pump?
not too hard of a job 1.drain radiator/block of all anti-freeze 2.remove fan shroud 3.remove serpentine belt 4.remove fan unless its electric 5.pull the hoses. 6.remove bolts holding the w/p in place 7.clean all gasket area of old gaskets 8.dry fit new w/p to make shure new pump is right part 9.put rtv gasket on block where w/p will mount 10.put rtv on new w/p 11.put new gasket on w/p 12.mount water pump and snug up the bolts do not tighten 13.after allowing rtv to set for 24hrs tourqe bolts to spec. 14.reverse steps 5 to 1 15.check for leaks.
Q:97 Dodge Stratus Timing belt & Water pump?
Non- interference engine.Meaning no damage. repair it. 100% guess here Parts: Pump / T-belt / Tensioner,Coolant - $140 your cost -200 shop Labor : 3 hours/Or free rate of difficulty 1--10 -5-
Q:My Whirlpool bath is clicking when I press the button, but no water pumps.?
Your pump either has a jammed impeller or the coupling is broken. These pumps are lubricated by the water flowing through and when you are pumping bubbles, you're not pumping water. Hopefully the tub was installed so there is reasonably easy access to the pump cavity.
Q:Where does the water go after it is sent to a pumping station?
Potable (drinkable) water pumps placed just outside the treatment plant boost pressure in the water mains, where it eventually gets to homes, businesses and hydrants via the pipe network. Most sewers flow by gravity (downhill) to a waste water treatment plant (or septic field). But if an area is too low to be serviced by a gravity sewer, an ejector pump is set at the bottom of a collection well which pumps the wastewater to a higher elevation in a pressure pipe called a force main. A good pump station will kick on about 4 or 5 times an hour and run for several minutes. Eventually it outlets to a manhole in a gravity system and ultimately the treatment plant.
Q:Which is the better option for a home water pump?
In case of pump failure, it's much easier to repair/replace a floor based pump plumbed with isolation valves and unions. I've replaced a few due to motor failures and flood damage. Arguably, the submersible pump wouldn't have suffered damage due to flooding. Another consideration is vertical pump height. A floor based pump has to draw a vacuum to induce water to flow up to the impeller. This limits the practical draw to between 25 and 30 ft. Much more than that height and the vacuum will exceed the vapor pressure of the the water, boiling it rather than pumping it. A special device can be used to boost the lift: an ejector is placed down the well. Water is pumped down to the ejector, which pulls additional water back up using the venturi effect. This method suffers from additional friction losses but has clear advantages. If you need to pump water up a well more than 20 feet vertical, you should consider a submersible pump, particularly if you are concerned about the possibility of the water table lowering.
