High pressure Water Pump

1.Introduction:

CDL/CDLF high pressure water pump is special in high pressure, made of stainless steel 304 or 316, all parts touch with liquid are of stainless steel. The pump is vertical non-self priming multistage centrifugal pump, which drived by a standard electric motor.The motor output shaft directly connects with the pump shaft through a coupling. The pressure resistant cylingder and flow passagecomponets are fixed between pump head and inlet and outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.

Q: How to install circulating water pump for cooling tower?: I think it should be installed on the outlet pipe of the cooling tower

Q: How many lift pumps should be used for 100 meters tall buildings?: Specific to calculate pipeline loss in order to know.. According to my experience, feeling that life would be 130 meters -140 meters to 110 meters can fire if the premise is the roof of a pump group

Q: replaced water pump and thermostat, flushed, opened bleeder valve had long life red colored original coolant, no visible leaks obstruction, when became hot on highway, accelerated quickly and temp back down to norm, eventually after 3hrs driving o.heated stopped and got towed home, new water pumps fins/pulley not turning as freely as old one, no leak out of inspection hole, hoses good shape.2001 2.2l ohv sunfire, air cond.: yep it should be hot.and the top radiator should be hot too when the engine is hot. if the bottom hose is cold when the engine is hot then it sounds like a clogged radiator. try this. after you get the engine hot, shut it down and feel the fins on the radiator next to the fan. if you feel cold spots then the radiator is clogged in some places.

Q: I need to do a new water level indicator interface for an experimental rig. I'm going to have the buttons that will start and stop the pump. And a column that will show the percentage of the water level in the experimental rig. Please help. I'm so clueless. And this is my final project. :(: They're equal (VB and VB6 variations of VB, surely VBA is super high-degree) in the phrases of where they rank within the excessive-stage/low-stage programming language rankings. Java is extra priceless without problems for the reason that it results in other matters (and could be very marketable on it's own), particularly c/c++/c# and net languages like php/javascript which have c-like cyntax. VB.Web and VB6 don't particularly result in so much (although they each support comprehend object-orientation). you can do the identical matters with visual normal that you can do with Java or C++. You are not able to do the identical things in VB as c++. For C# that you would be able to make a small case because it does aid c++-like code (hazardous keyword) but absolutely not VB.Internet (or VB6 most likely). Just are trying doing a C# an identical of stackalloc in VB.

Q: we live in the country in the warm months and have a portable pump that takes water from a 15 foot deep well. It feeds water to a toilet and a hot water tank mostly and a sink and shower and washer. We put the pump outside the bathroom and need to know how to start it, thanks!: I'm assuming it is an electric pump? You must be talking about priming the pump. You should add water to the system to create suction.

Q: looking for ideas and info to build a simple and rustic wind powered pump for a backyard pond. I don't want to use any elecricity and I would like to create something that once its made, will be trouble free and simplistic in operation. I esp. want info regarding the vane design and the method of drawing the water. I would appreciate any web sites, but I don't want to buy any pre-designed thing or plans.: I suggest you buy one ready-made if you want trouble-free operation. Here in rural NZ they're common on farms. You can buy versions that stop pumping when your pond water has reached a certain level. They don't need any electric power and they work for years without problems. As you probably know, suction pumps can only raise water about 10 metres, but I think you can buy wind-powered pumps that push the water up from below. The vanes are connected to the piston at the bottom of the bore by a linkage.

Q: The submersible, intermittent pump for my household water well, which is undergound out in the yard, “bangs” when it starts and stops, and vibrates the pipes when it runs. Any idea what might be causing this, or how to make it stop doing this? This all started about 5 months ago and has been getting worse.: It sounds to me like water hammer. There are a few ways to address it, probably the easiest is to add an expansion tank. To find out, try connecting a garden hose somewhere in the system, preferably a cold water pipe. Drain all the water from the hose and put a nozzle or plug on the end so the air can't escape, then turn the valve on. The air in the hose will act as a cushion and, if water hammer is the problem, you won't hear it while the hose is connected. That is not a permanent solution, just a simple test that might give you an answer. Good luck

Q: i have a 2003 dodge neon and my thermostat keeps rising to the highes level setting off the indicator (its not broken) i did have a leak in the raiditor and it was very notice able..after pacthing is up there was noproblem till yesterday now the thermostat keeps rising i admit the is very little antifreeze in ther and the rest is water but the is the same mixture tha was in the care that it was rinning off for the last three minths i cannot seem to keep the thermostat down my raiditor is in nee of repair but i m wondering if its the water pump does the water pum help regulate engine temperture? ther are no ivsible leaks and no drippiage could it be that i just need to put antifreeze or could it be the water pump or a broken raidiator? help i will give points for best anwser but really i just need help!: Did you use a radiator stop leak to repair the leak. If you did the radiator could be stopped up. The water pump only pumps coolant through the cooling system. If it has no leaks or the shaft bearing is OK, the pump is OK. Also since the car was getting hot, it may have effected the thermostat. And the head gasket will cause overheating if it's leaking. To check this, remove the radiator cap (while the engine is cold, to prevent being burned) run the engine and look for bubbles in the radiator. The radiator is probably the culprit. Hope this helps.

Q: When the pump is running with frequency conversion, the instantaneous power is greater than the power frequency operation, and the actual flow and lift are less than the power frequency. When running, the efficiency is very low. Why?: There is a running curve for the fan and water pump.Enough is enough

Q: 3 months ago I had to replace the water pump on my Jeep (for $600!!!). Now I have leaking again and they are telling me that I need a new radiator. I'm wondering how did they know I needed a water pump last time (it was leaking just like now) and not a new radiator like they're saying this time? I know nothing about anything, and I feel like I'm not informed enough to know what they're really doing. Is this common?: Could be both. The water pump may have been leaking. Did the leak stop after the work was done? If so then it was leaking. The radiator may just have lived out it's life. Corrosion will eventually cause these types of things. I don't know where you're located but $600 for a water pump is a rip off. Maybe you went to the dealer? If it's not under a warranty and you're not buying a new one the jeep does not belong at the dealership. I recently did my water pump on my 94. $100 including new hoses and about 45 minutes. So even parts mark up and $60 labor should have been about $210 or so. For the radiator they are about $150 again depending on where you are. See if you can get a 3 core. More cooling capacity almost the same price. If you're around Maryland e-mail me and I can help you do it yourself.
