(b) in mixed water tank outside, establish again a self-loopa mixing pump, the water inlet of described self-loopa mixing pump is communicated with the bottom of described mixed water tank, the water outlet of self-loopa mixing pump is communicated with the top of described mixed water tank, the work of self-loopa mixing pump is in harmonious proportion evenly the mixed water in mixed water tank, makes mixed water can not produce precipitation.
(c), before on-test, the dense mixed water for preparing in advance concentration known is poured in mixed water tank into to the operation water pump assembly; Pre-configured certain density dense mixed water is poured in mixed water tank, open the first switching ball and flow control valve on mixed water water inlet pipe, the dense mixed water prepared in advance mixes with the clear water in the water pump assembly pipeline, obtains the now flow of dense mixed water by the flowmeter on mixed water water inlet pipe; According to formula: mixed water concentration=(concentration of the flow of dense mixed water * dense mixed water)/(flow of the flow+water pump assembly of dense mixed water) of the test needed, obtain in sprinkling irrigation test needed mixed water concentration in the pipeline of shower nozzle place, start the test shower nozzle is carried out to the test of hydraulic performance.
(d) after having tested, inject clear water in mixed water tank, operation self-loopa mixing pump cleans mixed water tank, after mixed water tank has cleaned, remaining water in mixed water tank is poured out outside case.
In above-mentioned steps, when the mixed water capacity in mixed water tank be less than mixed water tank capacity 1/10 the time, again in mixed water tank, fill into the mixed water for preparing in advance same concentration, with warranty test, continue to carry out.
In above-mentioned steps, in order to understand in time the volume of mixed water in mixed water tank, can on described mixed water tank, establish a transparent water gauge.
In above-mentioned steps, described mixed water tank bottom surface determined by the piping flow of the water pump assembly of sprinkling irrigation test use apart from the vertical distance H of the water pump assembly pipeline center line of described sprinkling irrigation test use, when the piping flow of the water pump assembly of sprinkling irrigation test use is 0～7m
3During/h, the vertical distance H of the water pump assembly pipeline center line of the described sprinkling irrigation test of described mixed water tank bottom surface distance use is for being more than or equal to 0.8m, and the piping flow of testing the water pump assembly of use when sprinkling irrigation is 7～15m
3During/h, described mixed water tank bottom surface is between 0.6m to 0.8m apart from the vertical distance H of the water pump assembly pipeline center line of described sprinkling irrigation test use, when the piping flow of water pump assembly is greater than 15m
3During/h, the vertical distance H of the water pump assembly pipeline center line of the described sprinkling irrigation test of described mixed water tank bottom surface distance use is for being less than or equal to 0.6m.
In above-mentioned steps, after in test, completing, will mix fast the mixed water that water tank cleaned and discharge outside case, at described mixed water tank bottom, be provided with drainpipe, drainpipe is provided with the second switch ball valve, can by opening described second switch ball valve, the water in mixed water tank be discharged outside case fast.
In above-mentioned steps, spill in test site in order to prevent mixed water, increase a mixed tank lid in described mixed tank top, when the self-loopa mixing pump was worked, mixed tank lid can prevent effectively that mixed water from spilling in test site.
The technique effect that the inventive method reaches: the method for setting up a mixed water tank by the water pump assembly outside in sprinkling irrigation test use, realized in indoor sprinkling irrigation process of the test to testing the convenient and reliable adjusting of mixed water concentration of current, for the real performance parameter of shower nozzle in actual response sprinkling irrigation process of the test provides test basis and adjusting.
