- Q: How to install circulating water pump for cooling tower?
- This should be installed at the inlet of the cooling tower. The water at the outlet of the cooling tower is returned to the pool
- Q: About 3 weeks ago our water stopped. We replaced the switch at the pump and it was fine. Today when I was running water, it stopped again. I went and flipped the breaker on it, but it still didn't come on. About 20 minutes later, it started working again. Have you ever had this happen or do you know what the problem could be?
- The pump has a capacitor start motor. Electrolytic capacitors fail. The capacitor is not physically down the well with the motor though, just electrically connected. There should be a pump control box on your wall somewhere with a pump shut off lever on the side, some relays and a large motor start capacitor hidden inside the box. Kill the main power, open the box, remove the capacitor and replace it with a new one with the same number on it. You can get them at any pump supply place, or even just order it on the internet. I recommend taking a picture first for reassembly if you can't understand the schematic on the inside of the box. Sometimes electrolyte from the bulged out old cap obliterates the schematic anyway, so having a pic is a good idea. Look on the internet for motor start caps if you can't figure out which item it is.
- Q: Hello everyone, is the general household deep well pump capacitor how to pick up ah, 220V voltage, a capacitor, capacitor, there are 2 lines, but the motor is 3 lines, how can I put these 7 lines together?.Please don't copy professional theories from others.
- 220V has two lines (lines 1, lines 2)There are two lines of capacitance (line 3, line 4)There are three lines on the motor (line 5, line 6, line 7)3 11 52 64 7That's plain enough. To change the turn, change any two of the 5, 6, 7, three lines
- Q: How many kinds of pumps are there? What are the advantages of soft start?
- The starting modes of water pump are direct start, star triangle start, reactance start, soft start, step-down start and frequency conversion start.1, direct start, generally suitable for small power motors, generally only in the following 15kw pumps, cheap;2, the buck start is the star triangle conversion start, that is, the start is accelerated two times to reach the rated speed, generally in more than 18.5kw pump use, moderate price;3, soft start is gradually increased to the rated speed, the impact on the pump is very small, the price is relatively high, is generally 3 times the buck start;4, the highest frequency conversion is started, in addition to the advantages of soft start, but also can be set at any speed work, energy saving has significant effect.Advantages of soft start:1, the output torque of the motor can meet the requirements of the starting torque of the mechanical system, ensure smooth acceleration, smooth transition, and avoid the impact of destructive torque;2, the starting current to meet the requirements of the motor capacity, to avoid motor heating, causing insulation damage or burnout;3, make the starting current to meet the grid power quality related standards requirements, reduce voltage sag amplitude, reduce the higher harmonic content.

- Q: gould water pump model Jo5n
- i am assuming you are referring to jet pumps, and not a submersible, you cannot convert a deep jet pump to a shallow. the deep well jet pump has the foot valve down in the well casing. it uses two pipes that go to the foot valve. the deep jet forces water down the well and uses a venturi effect to draw water back up to the tank. the shallow water jet pump only uses one pipe in the well casing. the foot valve is in the pump itself. the venturi is created in the pump itself, and uses a vaccuum type effect to draw water up from the shallow well.
- Q: When I buy submersible pump, the other party did not inform is the aluminum submersible pump, water pump factory production of aluminum submersible pump illegal? Is it against the law to sell the pump to the pump without informing me?
- No, the state does not have special laws to prohibit the use of aluminium wireIn fact, the aluminum core wire or mechanical or good, low prices, especially in the dry environment of small and medium-sized mechanical and electrical, with good performance. Only in the submersible pump, because aluminum is easier than copper wire, moisture infiltration, bacteria and other corruption, and its survival time is sometimes less than copper wire. But the pump inlet, aluminum often requires rewinding coil, because of a small submersible pump well around Electromechanical General scrap. Therefore, the quality of submersible pumps will not generally use aluminum, but the production of aluminum submersible pump is not illegal, but in the sale should be based on the principle of honest business detailed notification.
- Q: Could it make coolant quot;Boilquot;? Ive heard myc ar's behavior is Normal, and most likely just heavy condenstaion as it DOES go away, also the behavior of the coolant and the tank.. but i DO know the Water Pump is quot;Weeping,or quot;Seeping,so i wonder what interaction that would have ont he Cooling side of the motor; what effects can it produce? What would i notice?My 1991 Calais 2.5L quot;Iron Duke,
- Water pumps have a small weep hole that leaks coolant when the pump seal is bad. If the mechanic saw water leaking from that hole, that's how he knew the pump was bad. It's not a hard thing to replace, and it's cheap. They can do it in an hour for $50 - $70.
- Q: Here is the deal...*Van over heats*Blows Cold quot;heatquot;*Coolant leaks (not into the oil)*Added coolant and water (nothing happened)*Started van, felt the hoses (no h2o flowing thru)Ive had this problem for a while. Some times my van drives just fine and heats just fine, then some days it wants to over heat and blow cool quot;heatquot;. Adding coolant to my van used to do the trick, but now its not working. If it is my thermostat that is broke, the water/coolant would still run through the hoses right?I really think its my water pump out, but I am not sure. Does this sound like my water pump? If so, I plan on changing it myself, how do i find step by step instructions to do so.... I have never done it before, but I cant afford to take it to a mechanic! Thanks for your help!
- Again, see last answer to your same question. You obviously dont know what the real problem is, could be water pump and might not be. Instead of wasting over 25.00 on a water pump and that not being the problem, why dont you take it to a reputable repair facility and have the cooling system analyzed and they can tell you EXACTLY what part(s) need replacing, then go from there. Nobody can diagnose your cooling system problem over the internet since we are not at your vehicle with a coolant pressure tester and block test tool.
- Q: the car is a 1973 Pontiac Lemans, 350 V8. Water pump needs to be replaced. It's obviously a mechanical pump that's in there now. I was thinking of getting something with more capacity (to start off) as I feel the car could do with a better cooling system (and I have to get a water pump anyways). I was thinking of getting an electrical pump as that would also free up a bit of power from the engine. From what I gather, by doing this it seems I need to switch to an electrical fan also. Is that the case? Any advice/opinions on electrical systems and set ups? Any recommendations?Thanks in advance to anyone who answers. Much appreciated.
