Operation and management of irrigation projects Suggestions

The main reason is that many farmers still ringing the economic benefits of irrigation projects. Irrigation projects on the existence of the following incorrect understanding and practice, and some mistakenly believe that an operation and maintenance of some suggestions for reference. Pump up the water immediately, no need to set the pre-run device; a 1 on wells,[link widoczny dla zalogowanych], pumps, confidential setting by professionals, to avoid the fear of a pump and more money, trouble and not set the pump in the open before the machine with the phenomenon of glass glass bottles with pre-cast units run about sad. Therefore, often occurs in oak management and use of motor-pumped well,[link widoczny dla zalogowanych], and is currently a one rubber bearings were burned, and even other parts wear and so on. Way under the water, who poured in whom security machine, where each side presents a number of simple pre-run tank device for a long shallow water, the one well has more than lO engine line up one by one, shaped shaft pump, the pre-run tank can use a capacity of one pump 2O ~ into the management of multi-machine use, not only the efficiency of water to wash and clean the old 30L plastic oiler, for the deep card-axis low, high cost, resulting in a large number of engine idle time, the pump can be used a capacity of about 150L wash clean but also to wells, pump management and maintenance is also more difficult. Cases of old oil drums, and then in the old oiler (-2 old oil drums) and the bottom side of the irrigation area, such as the Three Mile Village cart village of two-phase shallow wells, in the pouring side of a hose and then pre-run port connected to the pump wells, plastic tube tops finished pouring a time some farmers own land rush to gate can be easily added. And can be placed well inside the house is not up to the cost of the accelerator,[link widoczny dla zalogowanych], making the pump speed much higher than the rated speed, its more than 30 to 40 yuan,[link widoczny dla zalogowanych], with good results. For example, in a village cart influx of sand wells, wells and pumps are premature retirement; another 12 irrigation area Yuanxiao Wang Village, the long axis of the pump are set this one well, pouring a water (control area 8O acres) must provide easy device, since the completion of three years of the irrigation area, there is no time to overhaul Jue pump parts, not labor, down a quarter because of wear and tear of rubber bearings were raised pump. Repairs to spend 300 to 400 yuan, resulting in unnecessary additional water pipeline by the end of 3 exhaust economic losses. Therefore, to establish a strong sense of responsibility, maintenance around the irrigation area is currently only in the delivery pipeline end of the first set levels of management personnel, the implementation of a single pump single contract regulating a single well exhaust pipe,[link widoczny dla zalogowanych], and no exhaust pipe at the end. Our form of management, to avoid the phenomenon of a multi-machine pump. Through investigation and analysis of that: the end of the water pipeline pre-set 2, set the Run exhaust shaft, you can play over the first side not holding the role of the trachea; a l92 a {1) water or water in the pipe less case, the opening into the pipeline after the pump bearing body when the gas pipeline work by the end of the exhaust pipe outlet and the smooth discharge; 2) filled with water in the pipe case, a pump or stop, as when the first end of the exhaust pipe can work together role in enabling the water pipeline in a better state of freedom of movement; 3) can be reduced after the first open pipe open pump outlet pipe caused the increased value of water pressure; 4) can also reduce the work behind the outlet Pipe flow inertia due to the water pressure arising from increased value. Therefore, in the end beam pipe additional water holding the trachea, can better protect the role of the pipeline. End of the exhaust pipe of the set, the path can be hard plastic tube or pipe cement pipe installed directly on the tail, about the height l_Om cost of no more than 10 yuan 4 under certain conditions, can not soft-ground camp in the irrigation area of plastic, its water semi-fixed multi-channels, that is buried trunk, branch for the terrestrial mobile plastic hose. 4 May 1992, we are well irrigation area in the cart Yuanxiao Wang Zhuang Village, the village of Three Mile phase Inoue eyes were made of plastic hose and use by ground ditch to irrigate soil ridge compared. The results showed that: the use of ridge and furrow soil rather than using plastic hoses poured to save time, see test comparison table. Through investigation and analysis, we believe that there are two main reasons: First, a solid groove ridge of soil formation, the small size of irrigation and Land Leveling the second is a small diameter plastic hose, head loss and impact pump out the water. Therefore, if unwilling to spend money for large-diameter plastic hose, you have to make great efforts to smooth the face, the implementation of small irrigation, remove the ground plastic hose, this reduces the head loss, shorten the pouring time, thereby reducing the irrigation project in running costs. Some problems mentioned above, is often overlooked. We should actively carry out publicity work properly manage and use irrigation works.
