However, the selection of the mixing pump model will be severely limited by the water storage capacity of the pool. If a low-power mixing pump is installed in a large-capacity pool, the mixing effect will not be ideal. Sustainable Development Strategy of Energy Conservation in my country
Secondly, most of the current filter performance test platforms have relatively single functions, and can only complete some basic performance tests. From the water injection, sand addition, and stirring of the pool before the test, to the flushing and drainage of the pipeline after the test, there is no integration. This will virtually increase the difficulty of the test operation

The invention discloses an agricultural filter comprehensive performance testing platform, and belongs to the technical field of agricultural machinery performance testing. The agricultural filter comprehensive performance testing platform includes a platform water adding, sand adding and rinsing system, a sediment mixing system, a filter performance testing system and a drainage system. The agricultural filter comprehensive performance testing platform is a multi-functional, high-precision, easy-to-disassemble integrated filter comprehensive performance testing device, can simultaneously achieve the functions of water tank water injection, sand adding, mixing, pipe rinsing and rapid drainage, and completes the detection of flow passing capacity and a clean pressure drop performance indexof a filter; and at the same time, the filter turbidity and the removal rate of the solid particle concentration can be tested for the testing of different water quality including sand-laden water, reclaimed water and brackish water of different concentrations, and the filter capacity of the filter is tested.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery performance testing, in particular to an agricultural filter performance comprehensive testing platform. Background technique: [0002] With the increasingly serious situation of agricultural water competition, agricultural irrigation has gradually changed from traditional flood irrigation to water-saving irrigation integrating fertilizer and water. Modern scientific water-saving irrigation technology can not only alleviate a series of environmental problems caused by groundwater overexploitation, but more importantly, it can provide water and nutrients regularly and quantitatively according to the water consumption in the growth period of plants, which improves the yield per unit area of crops and fruit quality. social and economic benefits. Micro-irrigation systems have high requirements on water quality. For example, the flow channel or orifice size of drip irrigation emitters...
