example 1

[0025] This example is mainly to measure the anti-clogging performance of the emitter under the condition of recycled water drip irrigation. Before the test, 25 emitters (arranged in 5×5) were randomly selected for testing, and the drip irrigation emitters were connected with the bypass and the water supply branch pipe 5 according to the position of the drip irrigation pipe 6. The water drop that falls does not enter water container 7. Close the bottom valve 17, add an appropriate amount of regenerated water into the mediation water tank 11, open the first pressure regulating valve 2, the second pressure regulating valve 14 and the third pressure regulating valve 15 of the device, start the water pump 1, and adjust all the pressure regulating valves so that in a half-open state. Slowly twist the first pressure regulating valve 2, so that the pressure value observed by the pressure gauge 4 is at the target working pressure of H±100kpa, and then slowly twist the second pressure...

Abstract

The invention discloses a drip irrigation douche combination property test simple arrangement which belongs to the agriculture irrigation equipment. The water pump of the arrangement is installed on the bottom of the water-supply rack, and is connected with water inlet pipe and regulating tank regulating tank; and the water pump is connected with pressure regulating valve, filter, pressure gauge and water-supply branch pipe by primary perforated pipe. The water-supply branch pipe is respectively connected with drip irrigation douche; the water container is placed under the drip irrigation douche, the water container is fixed on the moving rack, the water accumulating tank is fixed on the middle part of the experimental bench, the regulating tank is connected with water accumulating tank, and is fixed on the left bottom corner. The device has simple structure, the system uses shunt pressure regulating principle together with pressure regulating valve to form three-level joint regulating test target working pressure control mode, which can rapidly approach to and lock the target working pressure, at the same time the reflux of water in the divider causes the water disturbance thoroughly which replaces the usual stirring means, the principle is simple, the test has high synchronism, which reduces the experiment error greatly, the invention has the merits of strong operability, low price, which can be achieved and popularized easily.

Description

technical field [0001] The invention belongs to the scope of agricultural irrigation equipment, in particular to a simple device for comprehensive performance testing of a drip irrigation dispenser. Background technique [0002] The emitter is one of the most critical components of the drip irrigation system. Its structure and its hydraulic performance have a great influence on the uniformity of irrigation, the ability to resist clogging, and the life of the system. Since the emergence of drip irrigation technology, relevant researchers at home and abroad have spent a lot of energy and material resources on the development of drip irrigation equipment. Since the design theory and methods of emitters at home and abroad are kept strictly confidential, few articles with practical guiding significance for the design of drip irrigation emitters have been published publicly. The development of drip irrigation emitters in my country is still in its infancy, and the design is mainly...
