Q: What is the function of boiler feed pump, condensate pump, vacuum pump and low drain pump in operation?: The feed pump is a pump for supplying water to the boiler and maintaining the water level of the boiler. The condensate pump provides water to the deaerator after condensing the turbine and provides water for some condensate users. Vacuum pump is to maintain the vacuum of the pump, the pump is to lower the drain in a timely manner to the next level of low pump

Q: Does it take more power to pump water with a 1 /12 hp bg motor/pump than one that is a spare pump/motor running dry,not connected to the system? I am trying to figure out how long it will run with an power inverter during a power failure.: put in a zone valve that way when the power goes out you can open the zone manually and heat with gravity,as the furnace cools it draws the heat from the top of the unit through the pipes and back to the bottom

Q: Weap seal is starting to leak and getting some noise from the water pump. These cars are not as easy as a 1969 Camaro to change the water pump. Can you please give me some guidance? Thx in advance.: The water pump is interior the middle of the front of engine and is pushed via the timing belt. There are brackets and covers, plus cooling followers and so on, to eliminate earlier attending to the pump. no longer a undesirable interest, and way much less annoying than doing the two head gaskets on that ingredient.

Q: I live in a condo building -- 3 floors, 7 units. In our storage units (right below my unit) is a water pump that was hooked up with the intent of helping the water flow to the 3rd floor. Everytime the pump goes off, it rattles, then makes a loud noise when it kicks off. The developers created a drywall box that houses the pump, which is surrounded by isolation, but it doesn't seem like it helps the noise. The pump also rattles the pipes that connect directly to the pump.My question is -- is this rattling normal for a standard water pump? If so, is there anything I can do to help cut down on the noise? If this is rattling is not normal of the standard water pump, what would it cost to replace it with something decent?: I do not know the kind of pump you are referring to. I will give my personal expertise. If it is a pump taking water from a tank, the piping might be loose, the knocking may be corrected with some air ventilation pipe. If it is pumping from a water tank: I suggest you look at a submersible pump capable of supplying water to 3rd floor. This kind of pump is less noisy. The noise at start, is the electric starter, and the noise at the end is when water returns and seals the stop valve. Also some air may be in the pipe, you need to purge the pump, as often as needed, try this first, and then the others. Good luck

Q: A 0.13hp electric motor on a water well pumps water from 30.23m below the surface. The density of water is 1.0 kg/liter. How many kg of water does the motor pump in 2.20hr?: It is known that 1 hp = 746 watts, so 0.13 hp = 97 watts = 97 Joules/s The amount of work to lift 1 kg water a vertical distance = 30.23 m = mgh mgh = (1)(9.81)(30.23) = 296.6 J no. of seconds in 2.20 hr = (2.2)(3600) = 7920 s total work output of a 0.13 hp pump in 2.2 hr if 100% efficient = (7920)(97) = 768,240 J no of kg lifted by 100% efficient pump/motor in 2.2 hr = 768,240/296.6 = 2590 kg ANS

Q: I think my water pump is leaking and I want to replace it, but I can't figure out how to get the pulleys off. There is a large nut on the shaft that the pulleys are on, and I can't figure out how to remove it, or if the nut is attached to the shaft, and the entire shaft is supposed to come out, or how it's set up. Please help. Pictures would be great if possible. Thanks!: take bolts and nuts off of fan and take off , might have to pry because of rust , corrosion . then take bolts out of the water pump , once all bolts are out , tap with rubber hammer or pry by hand, pump will separate , because of close quarters with radiator be careful not to damage radiator by accidentally hitting it

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?: When you buy the pump, you can ask the manufacturer to give you an FM curve so that you can see the change in the efficiency of the pump as the frequency is adjustedSend you a document in the hope that I can help you

Q: I was vacuuming up water from my basement I assumed was from the rain, suddenly water started spraying out of a blue pump at the base of my furnace, don't know what the pump does or why its spraying but its making an awful mess.: Blue pump, usually found on the floor near the furnace (sometimes mounted where plenum meets the furnace frame) is a condensate pump. One of the products of combustion is water. This water is drained from the ventor motor (a motor which runs and sets a artificial draft inside the combustion chamber) to a drain nearby or a electric pump which then pumps the water over a longer distance to a remote drain. If the pump's discharge outlet gets plugged from dirt the result is usually the mess you see. Remove the cover plate of the pump housing, clean it out and run a wire with a small rag attached as a snake through the tube to drain. There is usually some type of float switch inside the pump housing so make sure it is free to move. Check for operation by pouring some tap water in it and move the float switch to on (up) One final note and this is very important. If the pump or tube to drain is filled up with a crud that resembles paste, call your local trusted HVAC tech for furnace service. This condition can be an early sign of heat exchanger failure and is a major safety concern for your family

Q: How to remotely control submersible pumps?: Now the remote control of submersible pumps and pumps is very mature, and the cost is relatively low. We use the Ji'nan Huichi electronic pump remote controller controlled step-down start control cabinet, convenient Clockwork SMS can control the pump start and stop, and return to the working condition of the water pump, water pump overload or lack of power can also feedback fault message to the responsible person

Q: About 2 months ago I started hearing a noise coming from my bathroom that sounded like loud humming every 3 or 4 seconds after I would turn on the water or flush the toilet. I noticed that when this noise happened the water pressure would increase and then it would go back to normal. Then the noise started to get louder. Last night while my husband was taking a shower the water lost pressure and then completely turned off. Now I have no water at all whatsoever except for maybe a few drops when I turn the faucet on. I have a private well and when I bought the house I was told that the well is underneath one of my bedrooms because the house was built on to and they built over the well. I know I can get to the pump from the crawl space. Has anyone had this problem or does anyone know what it might be or maybe even how much it could cost to fix?: Hi. You could have a pressure tank that is in need of replacement or adding air to. The air cushion in the tank has either become compromised or has disappeared completely leaving no air cushion to let the pump build up pressure against. The pump is basically running every time you use even the smallest amount of water and this will basically cause the pump to self destruct. The next thing you may have is a bad pressure switch that is both causing the noise and the pressure variations from the nature of the points being bad. This is not expensive to fix. Under forty bucks. The other fix may run into the several thousands. Sorry. Hope this helps.
