    Can I use the sun to power a pump? @STARFLO PUMP WILL PROVIDE YOU THE BEST ANSWER FOR IT. Any renewable energy source can make the electricity you need to power appliances, including pumps.  Solar electric cells convert sunlight into DC electricity that can be routed directly to DC appliances, or can be stored in batteries for use when the sun is not shining, or can be inverted into AC electricity to power AC appliances. Solar well pumping generally refers to the use of sunlight to power pumps, while the sun is shining.   These are simple systems that do not incorporate batteries for storing electricity.  In essence, the water tank or cistern acts as storage.  If you can pump water fast enough and your cistern is big enough, then you do not need to pump during the night or during cloudy days. Batteries are generally not necessary in remote water pumping situations, as long as your system is sized properly and you have enough water flow from the water source. Is solar water pumping economically feasible? The reliability and economy of solar electric power make it an excellent choice for powering remote water pumping.  Cattle ranchers all over the world are enthusiastic solar pump users.  Their water sources are often spread over many miles of rangeland where utility power is not accessible and where refueling and maintenance costs are high for generator use. If your water source is more than 1/3 mile from utility power, solar is a favorable economic choice.  This fact is substantiated by a number of rural electric cooperatives across the U.S.  These co-ops actively promote use of solar pumps because the cost to extend new power lines is prohibitive. Where do solar pumping systems work? Solar panels should be located in a sunny spot where no shading occurs.  Altitude is not a factor, but height off the ground will affect whether or not you are able to keep them clear of snow. Panels should be angled optimally for solar gain, particularly during the shorter winter days.  If your site is in the northern hemisphere you should point your panels to true south.  The reverse is true for places in the southern hemisphere.  For many locations there is quite a difference between magnetic south and true south, so you should consult a declination map before setting your mounting structure. The solar panels should be tiled up from horizontal to get a better angle at the sun and to help shed rain and snow.  For best year round power output, with the least amount of maintenance, you should face the solar panel(s) true south at a tilt angle equal to your latitude with respect to the horizontal position. If you are able to adjust the solar panel seasonally, a good rule of thumb is: Latitude minus 15 degrees in the summer Latitude in the spring/fall Latitude plus 15 degrees in the winter

    The consistent taking off of the cost of power pushes individuals to search for approaches to lessen electric receipts. In the event that you imagine that the main way you can drop down your energy bills is by ceasing from utilizing AC equipment, musical frameworks, and other real apparatuses, reconsider. Sunlight based power is certainly the cleanest wellspring of vitality. There is no blazing of coals or other relic powers and at the time it doesn’t create nursery gasses. In this way, it truly doesn’t have any unkind impact on nature. There is positively no restriction to sun oriented power. There is all that could possibly be needed to go round for everybody; there could never be a period when sun powered vitality would be depleted. Actually, the measure of sun oriented vitality achieving the terrain every moment is more than the vitality expended yearly by the whole planet. The wide usage of solar pump can be seen in most part of the world as most of the individuals are nowadays considering to use these pump ranges to accomplish their varied purposes. The best thing with a solar pump system is that you can get water when you require without even making environment hazardous or to put lots of load on to your pocket in terms of maintenance and as well as others. Government is also subsidizing in this segment and helping individuals to install a solar pump at their venue and to contribute towards making environment hazards free.

  • RV Water Pump Main Jobs
    RV Water Pump Main Jobs

    2017-04-19 09:41:15

    RV water pumps take the water from your tank, up into the piping system of your rig.  The RV water pump’s job is to increase the flow of the water, and stabilize it’s pressure.  In other words, it’s pretty important. The average RV comes with a 50-gallon to 200-gallon fresh water tank.  This water is your lifeline when traveling, or when camping without hookups.  Your ability, to consume the water in your tanks, comes via the little wonder known as: the RV water pump. Here are a water pump’s two main jobs: Job #1 The first job of the RV water pump is to provide pressured water from your rig tank.  RVs store their water in built-in tanks, which are usually located in the base of the motorhome or trailer. Your unit has three types of tanks.  The fresh water, gray (or used) water, and black (or waste) water tank.  A pump allows you to get water from the kitchen and bathroom faucets, and keeps the shower and toilet flowing.  Most RV water pumps are small and run off your RV battery.  (Generally, that means water pumps are 12 volts). There are a few major RV water pump brands. The key is finding a simple, easy to install pump, that features a quiet motor.  Aquatec boasts two units which are both quiet and offer basic installation.  Remember, an RV water pump will make noise, especially if you have multiple faucets open at one time.  This is not unusual.  Look for a pump with a 4-chamber design.  They offer greater water and pressure flow, along with a smooth overall action.  A good RV water pump will produce an even flow of water.  A jerky flow indicates variable speeds, with not enough pressure.  If choosing a unit at a service center, ask them to demonstrate the differences between the models that they use, before deciding on a purchase. Job #2 The second job, of the RV water pump, is to provide a certain amount of water per minute.  Trailers or campers may use pumps that produce 3.5 gallons of water per minute.  Larger motorhomes may use pumps that provide 5.3 or greater gallons per minute.  Gallons of water per minute equate to pressure per square inch, or psi.  When your rig is connected to city water, it will often bypass the RV water pump, because city water is already pressurized.

  • THE BASICS OF SOLAR WATER PUMPING
    THE BASICS OF SOLAR WATER PUMPING

    Solar water pumping systems are a modern but field proven means of pumping water in locations where access to grid power is not available, or where the grid is not reliable. These systems use photovoltaic (PV) cells to convert sunlight into electricity to power DC pumps which can be used to pump groundwater or surface water. A typical system comprises the following elements: The water source: This could be a groundwater source, such as a well or borehole. Alternatively it could be a surface water source such as a river or pond. The pump: Depending on depth to water, pumps of either the submersible type or suction type can be used. In the most common solar systems the pumps are powered by DC current, which require considerably low operation and maintenance costs than conventional AC pumps and provides greater efficiency. The PV array: Arrays are formed from groups of photovoltaic (PV) cells, aligned to give suitable sun exposure at the site location. The PV cells generate DC power when the sun is shining. The PV array is normally mounted on a stand or mount to allow it to be aligned to maximize sun exposure. The pump controller: This unit allows the pump to be controlled and regulated and will be connected to the pump and electrical grounding system. Optional battery bank: The PV units only generate power when the sun is shining, and so do not work at night and on cloudy days, One solution to provide continuous pumping is to connect banks of batteries to the PV array to store excess power, to be drawn on when there is no sun. Optional generator back up: Another option is to provide a petrol or diesel driven AC generator: intelligent control units make the changing between power supplies automatic. Other renewable energy sources: Solar PV can also be combined with a wind turbine: taking maximum advantage of the natural energy resources – solar power when the sun is shining and wind power when the wind is blowing. Discharge pipework: This pipework carries the water from the pump to the storage tank and to the end use. It is important that the discharge pipework is designed so that the pipe materials, diameter, layout and fittings are arranged to minimize frictions losses in the pipework. This will help maximize the efficiency of the pumping system. Water storage tank: A storage tank is a key part of most solar pumping systems, to ensure constant availability of water, 24 hours per day. The tank capacity should be designed store enough water to allow for water demand on rainy or cloudy days (no sun days) when pumping will be limited. The size and dimensions of the storage tank should be determined based on the required number of days storage. In reality, each solar water pumping system is unique. Getting the most benefit from a system requires research and design before the first PV module and pump is purchased and installed. Each component must be carefully matched, and proper planning is essential – so the final system will be efficient and reliabl...
