Irrigation activities in modern agriculture is a complex interaction between electricity consumption and water use nangben firm , market conditions , and the application of technology and knowledge to ensure the best design entire irrigation system . Understanding this previous issues of water and energy today with developments in pump technology has contributed to building the pumping system to best meet the needs of a modern agriculture , to the purpose of enhancing and improving performance
The challenges in agriculture requires new techniques to boost productivity . Agricultural market is changing rapidly , so today's farmers can not rely only on the technology and practices of the past , besides
To keep productivity high and continue to compete in agricultural markets , farmers need to constantly focus on reducing production costs , increase workforce performance , including optimizing the power consumption through the application use of new technologies and use of water resources better . And so the pump system used in irrigation purposes plays a very important role

What is Water ?
Understanding a simple way , is watered by human action to bring water to the tree trunk and roots create a certain moisture , helping plants grow. It is also possible to add fertilizer and chemicals into an irrigation system , irrigation and also as protection from frost .
The success of agriculture depends on the problems farmers have enough water to irrigate or not . If you look back on the period between the last century , the popular belief , water resources are endless . Today, we all recognize that water resources should be managed . This is not just a matter of adding more and more mouths to feed , people today consume more calories and eat more meat , which requires more water to produce food , food .
Power consumption is also a problem for farmers today . Money power to run the water pump is one of the most costly expenses for farmers , so that many people still did not know the use of more efficient power can help save money how big .
Modern agriculture requires irrigation solutions to optimize uniformity of irrigation water , reduced electricity costs and protect water resources , and keep productivity at its highest level . Agricultural market is changing , and these changes require a focus on promoting the application of knowledge , experience and the overall water solution combine all items .
What should be considered when watering plants
Irrigation activities began finding water for crops from groundwater or surface water through canals or reservoirs . The next step is treatment , if necessary , and probably more on fertilizers and chemicals . Finally , water is pumped to the plant uses many different techniques , such as flooding , sprinkler systems or drip irrigation / spray.
The spray irrigation system mechanically , such as rotary irrigation , are effective measures for lon.Cac area such systems usually come with pumps that can provide water and pressure needed - and more than necessary , if required . Normally, a valve will handle traffic problems and excessive pressure .
Drip irrigation system for watering and misting with low pressure , in places that require the ability to reduce evaporation and runoff as much as possible . Keep steady pressure is an important requirement to ensure uniformity of irrigation water in each area of the system , and this could be the measures most power-saving irrigation , if managed properly . To do this requires that the system must be able to compensate for fluctuations in traffic , to ensure the pressure does not change , while the separate input areas .
A booster pump system used by inverter control , pump speed regulator controls the pressure in the pipeline - capable of adapting to the changing situation and to ensure a stable pressure .

The traditional methods and a solution pump
The groundwater extraction requires common submersible pump or pump turbine vertical axis to bring groundwater to the surface . With the collection of surface water , centrifugal pump with many different configurations , pump and pump suction oysters are commonly used solutions .
The pump requires to meet the changing situation on the ground or lower , impact on the pressure and flow required from day to day and from season to season . A pump system must be able to provide a proper flow and pressure required at the pump hose . The simple solution is to pump size greater than necessary , to meet the pump may be the worst situations . However, as a result, the pump will almost never operate at its optimum operating point . It would create too much pressure and consume too much power , which is not used at all effective .
Previously, the water is usually distributed from water - can be surface water or ground water from canals or reservoirs - with low pressure or by pump stable operation with only one speed . Irrigation water from the sprinklers for trees , covered only focused surfaces without paying much attention to water runoff , evaporation through trees or blown away . The soil moisture monitoring to ensure uniform dispersion over the entire irrigated area is a relatively new way .
However, pressure management has long been a problem , and over the years , the pressure relief valve has been widely Using The decrease in system pressure . However, the installation costs are quite expensive and van maintenance and regular replacement , not only that the valve operation also consumes a lot of electricity.
If we assume that a system of irrigated agriculture is a modern car , the engine and pump , not whether it's worth it if you continuously drive capacity and speed control by braking ? This is a fairly common approach for irrigation pumps .
If a pump is required to operate continuously at the most powerful level - such as when in the clear corners - fuel waste . Request changes to optimize power usage for a rotating shaft applications can be easily met by using a speed-controlled pump . So that can save power significantly while maintaining pressure .
Meet the challenges of modern agriculture
The complete pump system instead of the large pumps , isolation is the appropriate direction . Take, for example , can eliminate the use of expensive pressure relief valve and take a long time to maintain constant pressure by investors to pump controller to manage stress effectively . Doing so will save costs in the long term , reduce the need for maintenance , and reduce power consumption .
Can confirm the same valve used for spray irrigation system . A better way is to use a speed-controlled pump and a pressure sensor on the axis of rotation , will automatically adjust the operating condition of the pump to meet the requirements of the axis of rotation . Thus will ensure equal amount of water , and energy costs thap.Mot pump controller will bring a number of benefits such as protection of not leaving the pump running dry or unstable power source , extend the life of the pump .
The level rose or fell by surface water or groundwater levels will significantly alter the technical regulations of the pump system , because the vibrations would change the head . A single- speed pumps are calibrated to pump water up from the lowest water level will waste a lot of electricity when water levels rise . In this case , a speed controlled pump will be able to adjust the column pressure and flow to compensate for changes in water levels , reducing electricity costs .
There are many different applications of pumps for irrigation in agriculture . The key to success is to use intelligent pump controller ( inverter control system ) , designed specifically for your application .
Designing a modern irrigation system
We need a thorough consideration of the specific applications in agriculture in new directions , and in particular we need to design irrigation systems in practical applications . Pumps should be more closely linked to the remaining items of the irrigation system . By that means the pump should be designed to be compatible with other devices of the irrigation system , or watering equipment must be designed to be compatible with the pump .
How do nowadays is to install a simple pump are capable of pumping more water than necessary wasting both money and power . Go back to the pump as comparing automobile engines : Buying a too -sized motors and mounted in your car will be costly and does not guarantee a pleasant trip and less gasoline !
Applying to an irrigation system , which pumps must do more than just pump water into pipelines to operate effectively . For example , installing more speed inverter that will improve the efficiency of underground water suction pump directly into an irrigation system . It can be taken to improve the efficiency and surface water distribution network using the multiple pump booster system , and in all fields , the system will monitor and control the flow of water protection by protecting the pump not idling , motor malfunction or power flickered .
All these factors need to be fully incorporated into the design to create the benefits that a modern system of irrigation can bring to farmers . Maintaining the flow and just enough pressure in the pipe and sprinklers at each kWh will mean more water pump and power saving , which is one of the most expensive Terms of agriculture .
Previously, we discussed the importance of maintaining a constant pressure in a rotary irrigation system . This problem becomes simpler if the spindle is equipped with an aerosol can and a piece of angle . Immediately after aerosol and corner piece into position , the pressure in the pipe will drop spindle , and it will affect the uniformity of the irrigation system .
The solution is to replace the pump with a spindle speed controlled pump , the pump will immediately react to the phenomenon of pressure drop and spray angle intersecting segments . With such operation , can maintain a constant pressure in all the nozzles , and thus creates uniformity .
A modern pump system , the pump can not only talk about . Inverters , intelligent control and even remote control device ( PC connection ) , requires all incorporated into a watering system .
The future : comprehensive solutions , customized to suit the application
The interpretation on this issue shows the need for careful consideration of the entire irrigation system and the compatibility of each device , customized to suit the requirements . This requires experience and knowledge , and the ability to follow the flow of water from the plant - from where fetching water , through the treatment system lyva distribution network to place trees , all need to be monitored and carefully tuned .
Modern agriculture requires a broader understanding of the compatibility of the devices , and systems to ensure farmers can cope with power consumption issues and water supply , is separating the field can save , generate additional profit per hectare .
This is not a task that can be done alone , all the relevant factors in the region that need to be taken into problems , such as soil conditions , crops , topography , and the type of information . Pump controls including monitoring and intelligent management 's direction in the future .
Power savings can be realized - and not less . Increased benefits for the farmers , besides lower operating costs , water is applied to crops to flow more accurately , thus better harvests , increased profits , better water management , ensure sustainable agriculture in the future .
