The Study of Parameters and Reliability of Low-intensity Irrigation in the Conditions of Azerbaijan

In recent years, both in the Republic and in the CIS and far abroad are developing low-intensity stationary systems of irrigation, consisting of Micro Sprinklers, impulsive actions, aerosol auto oscillatory action sprinkling irrigation, auto oscillatory action auto oscillatory action combined, the drip, drip pulsing and a number of others. This is because low irrigation system has a number of significant advantages over other methods of irrigation. Especially promising the creation of automated sprinkling systems impulse machines, combined, auto oscillatory action stepper auto oscillatory action rocker type, pulse-airborne apparatus auto oscillatory action, etc. It should be noted that these systems allow to reduce the capital cost of their construction, also ensure the principle as “sprinkling” or “drip” in condition of daily water use plants. That is to create optimal conditions for the growth and development of plants during their growing season (Figure 1).


Introduction
In recent years, both in the Republic and in the CIS and far abroad are developing low-intensity stationary systems of irrigation, consisting of Micro Sprinklers, impulsive actions, aerosol auto oscillatory action sprinkling irrigation, auto oscillatory action auto oscillatory action combined, the drip, drip pulsing and a number of others. This is because low irrigation system has a number of significant advantages over other methods of irrigation.
Especially promising the creation of automated sprinkling systems impulse machines, combined, auto oscillatory action stepper auto oscillatory action rocker type, pulse-airborne apparatus auto oscillatory action, etc. It should be noted that these systems allow to reduce the capital cost of their construction, also ensure the principle as "sprinkling" or "drip" in condition of daily water use plants. That is to create optimal conditions for the growth and development of plants during their growing season ( Figure 1).

Moves the study
Automated watering crops the basis for high yields and productivity. Therefore, from the elements and devices used automatics require reliable and uninterrupted operation. Therefore, starting from the design stage through these devices and the production and operation, reliability issues, because the problem of reliability is not only technical, but also an important economic task. Reliability theory developed in recent decades, offers a great opportunity for a qualitative assessment of the reliability of existing irrigation technique, including micro irrigation systems. Reliabilitythis property of equipment or system to perform specified functions to maintain their performance within the required period or time required. From among the existing irrigation technique, stationary sprinkling system consisting of a large number of similar elements in a specific order on the field and required for the irrigation of crops.
Determining the reliability of one of these elements will decide the reliability of systems. Reliability issues fixed irrigation systems in particular, equipped with sprinkling installations engaged in many of the scientists in the former Soviet Union and abroad. To examine the elements of the calculation on reliability of low-intensity sprinkling (for example pulse sprinkling auto oscillatory action) should consider the technological feasibility and sprinkler systems. Optimal low irrigation system parameters were determined by us by searching for the specific functions listed minimum cost with UD . Depending on the area of the system S; aspect ratio θ; the cost Studies have shown that the most economical option is the simultaneous operation of all sprinkler devices system, i.e., when the system is produced by the limit dispersal of current irrigation [3] in this case has a minimum at points determined by the expressions:

Where is
Substituting in the formula (3) and (4)  x -7 m/s, the following optimal system settings l= 50m, N= 22, x = 10, y = 8 obtained using the following programs and formulas (4.5). For other crops and natural-economic conditions these parameters are defined similarly. Obtained values of N, l, x, y, (D) opt . I -enable you to define the basic construction and technological parameters of irrigation equipment (impulse sprinklers apparatus self-oscillating action): as head n 2 , corresponding pressure start splash RV 2 , head n 1 , the pressure end splash r 1 ; constructive volume pneumatic accumulator W 0 and nozzle diameter (D) [3,5]. It should be noted that equation (6) matches the water supply and water plants, and equation (7) and (8) tele control channel irrigation, but to appoint him constructive value parameters in accordance with the requirements of noise items tele control systems [3] Start pressure dissipation of impulsive actions self-oscillatory apparatuses splash leads to dispersion of their volumes Δ splash W layer and therefore rain m, so how are they related dependencies.   [3,6].

Discussion of research results
As a result of special research received the following relationship between the average service life of parts made of rubber or plastic t Wed , the average number of cycles N # 0 a year and experimental aging value of these materials in the water t 0 equal to 6.8 years: In addition to these activities required to address the optimal level of operational reliability of stationary systems should develop institutional arrangements. For organizational activities of particular importance was the implementation of preventive works and correctly spent time. The timing of prevention is one of the main problems of preventive maintenance, which is closely linked to the content of preventive works and the Organization of their execution [7]. These terms are usually defined in the study the

Scientific conclusions
Expelled us measure perfection is appropriate with a view to selecting the best design because it is economically summarizing indicators of maintainability of systems security, persistence, and sprinkling.
