Factors TO KNOW ABOUT FOUNTAIN PUMPS
出典: くみこみックス
When replacing a fountain pump or choosing a new a single, first there are some key terms to keep in mind:
"Head": This is the maximum vertical lift of the pump. For instance, a 6' head indicates the pump is rated to pump water up to 6 feet high. Note, even so, that at 6 feet the pump would be offering very little water, with gallons per hour around zero. So if you need to have to pump, say, 200 gph at 72", you will most likely require about a 300-600 gallon per hour pump to do the job.
"GPH" : Gallons per hour, generally rated at diverse heights
"GPM" : Gallons per minute, generally rated at different heights
"Pump Curve" : The quantity of water volume "curved" according to numerous heights. A 500 gallon per hour pump, for instance, might pump 500 gallons per hour at " lift, 350 gallons per hour at 24" of lift, and so forth. When purchasing a pump for the initial time or when in search of a replacement pump, it is vital that you know how several gallons per hour you want jupiter water ionizer talk to pump and at what height (head).
Water Volume The total volume that you will be pumping is controlled by a handful of variables. A single aspect is the size of the pump, as covered above. But you also ought to consider how wide your tubing will be. Tubing is best ionizers discussions measured in two methods: inside study water testing equipment diameter (i.d.) and outdoors diameter (o.d.). Very skinny i.d. tubing will tremendously decrease water flow. Numerous buyers are shocked when they locate that, after hooking up their 500 gallon per hour pump to 1/2" inside diameter tubing, they are only obtaining what they take into account a trickle.
We had an engineer do some calculations for us to illustrate the dilemma. Using a 300 gph pump with 1/2" tubing is going to restrict your flow to 253 gallons per hour. By escalating the pump to 450 gallons per hour, but nonetheless employing 1/two" tubing, you will improve volume only slightly, to 264 gallons per hour! The lesson is this: When buying a pump, uncover out what size of tubing is supposed to go with it. Another dilemma is operating the tubing too far. Extended lengths of tubing develop resistance. If your pump calls for 1/two" i.d. tubing, for instance, but you are operating the tubing twenty feet from the pump, it is
a excellent thought to use three/four" tubing instead so as not to cut down also much on flow.
How a lot water do I need to have? What size of pump? This question is answered in element by whether you want a "trickle" or a roar. When you get a fountain, you will typically uncover a encouraged flow. For waterfalls, use this as a rule of thumb: for every inch of stream width or waterfall "sheet," you will need to deliver 100 gallons per hour at the height you are pumping. So if you are constructing a 12" wide waterfall that is three feet tall, you want to get a pump that will be pumping 1200 gallons per hour at 3 feet of height. For tiny ponds, anytime achievable, it is a good idea to recirculate the water once
an hour, a lot more typically if possible. As a result, if your pond is 500 gallons, attempt to purchase
a pump that will recirculate water at a rate of 500 gallons per hour. For genuinely
big ponds, this is not needed and is far too pricey.
