Problems solved by technology

[0022] To sum up, the main problems of the existing experimental devices are: (1) the performance is single, there is no comprehensive experimental device, and only a single performance test can be carried out
(2) There is no uniform standard for various devices, such as the South African device, the test length is too long, the water head loss is large, which affects the test accuracy, the Netafim test device cannot test a single emitter, it can only be used as an online test for the manufacturer, and does not meet the requirements of irrigation instrument evaluation specification, and can only test hydraulic performance
(3) It is not convenient to test the anti-clogging performance of the emitter in the laboratory

Abstract

The testing equipment for testing antiblocking and hydraulic performance of irrigator of microirrigation system includes supporting frame, supporting pipe, capillary or drip-irrigation tube communicated with supporting pipe, water pipe communicated with supporting pipe and water-sand circulation supply device communicated with water inlet of water pipe. The water-sand circulation supply device includes mixing tank communicated with water pipe, oblique water-collecting channel positioned under the capillary or drip-irrigation tube and the water outlet of the oblique water-collecting channel iscommunicated with mixing tank. Said invention is a comprehensive testing platform capable of testing hydraulic performance of irrigator and its antiblocking performance.

Description

technical field [0001] The invention relates to a test experiment device, in particular to an emitter anti-clogging and hydraulic performance test device for a micro-irrigation system. Background technique [0002] Micro-irrigation technology is a local irrigation technology that uses micro-irrigation equipment to assemble a micro-irrigation system, distributes pressurized water to the field, and moistens the soil near the root of the crop with a small flow through the irrigator. One of the characteristics of the micro-irrigation system is that the water flow rate of the emitter is very small, so the outlet hole of the dripper is very small, generally only about 0.7-1.1mm, so the Achilles heel of the micro-irrigation system is that it is easily blocked by dirt in the water; the micro-irrigation The second characteristic is that the irrigation uniformity of the system is high. In addition to being affected by the system design, the irrigation uniformity of the system is mainl...
